     BACKGROUND 
     Field 
     The present disclosure relates to an information processing device, a control method, and a recording medium. 
     Description of the Related Art 
     With regard to a communication system where an information processing device such as a smartphone or the like and a communication device such as a printer or the like perform communication, there is known an information processing device that performs connection processing where an external device to which the communication device is to be connected is decided, and the external device and the communication device are connected. Japanese Patent Laid-Open No. 2013-219430 describes a user device that connects an access point and a printer in accordance with the connection status of the user device and the access point. 
     Generally, in a case where a printer is already connected to an access point by connection processing having been performed where the printer and access point are connected, the user device does not need to perform reconnection processing. However, the device described in Japanese Patent Laid-Open No. 2013-219430 can execute connection processing to connect the printer and access point, even though the printer and access point are already connected. Accordingly, the device described in Japanese Patent Laid-Open No. 2013-219430 can unnecessarily use resources by executing connection processing. 
     SUMMARY 
     What is needed is to suppress unnecessary use of resources occurring due to executing processing to connect an external device and communication device in a case where the communication device is connected to the external device. 
     A control method of an information processing device that communicates with a communication device includes accepting a connection processing instruction to connect the communication device with at least one external device, and performing processing to execute newly, in a case that the connection processing instruction is accepted and the communication device is not connected to any external device, the connection processing wherein a case that the connection processing instruction is accepted and the communication device is connected to at least one external device, the connection processing is not executed newly. 
     Further features will become apparent from the following description of exemplary embodiments with reference to the attached drawings.

The display unit  108  includes light-emitting diodes (LED), a liquid crystal display (LCD), or the like, and displays data and notifications of the state of the information processing device  101 . A soft keyboard including numeric input keys, mode setting keys, an OK key, a cancel key, a power key, and so forth, can be provided on the display unit  108  to enable user input to be accepted via the display unit  108 . 
     The communication unit  109  is a component that connects to the communication device  151 , an access point  131 , or the like, to execute data communication. The communication unit  109  connects to an access point (omitted from illustration) within the communication device  151 , for example, thereby enabling communication between the information processing device  101  and the communication device  151 . The communication unit  109  can directly communicate with the communication device  151  by wireless communication, or can communicate via an external device that exists outside of the information processing device  101  and the communication device  151 . The external device includes an access point that exists outside of the information processing device  101  and the communication device  151  (access point  131 , etc.), and a device that is not an access point but can relay communication. 
     Examples of wireless communication standard (format) include, but are not limited to, Wireless Fidelity (Wi-Fi®) and Bluetooth®. Examples of the access point  131  include, but are not limited to, devices such as a wireless local area network (LAN) router. 
     In the present embodiment, an arrangement where the information processing device  101  and communication device  151  directly connect without going through an external access point will be referred to as “direct connection”. An arrangement where the information processing device  101  and communication device  151  connect via an external access point will be referred to as “infrastructure connection”. The information processing device  101  transmits print jobs for the communication device  151  to print, via the communication unit  109  in the present embodiment. Jobs that are transmitted are not restricted to print jobs, an can include scan jobs for the communication device  151  to perform scans, setting commands to change settings of the communication device  151 , and so forth. 
     The short-range wireless communication unit  110  is a component that wirelessly connects to devices, such as the communication device  151  and so forth, at close distance to perform data communication and performs communication using a different communication standard from the communication unit  109 . The short-range wireless communication unit  110  is connectable to a short-range wireless communication unit  157  within the communication device  151 . Bluetooth® Low Energy is used as the communication standard (format) for the short-range wireless communication unit  110  in the present embodiment. That is, the short-range wireless communication unit  110  includes a Bluetooth® Low Energy unit. 
     The Bluetooth® Low Energy unit includes a microprocessor that processes wireless communication and a wireless communication circuit that transmits/receives data by wireless communication. The microprocessor includes RAM and flash memory. Accordingly, the short-range wireless communication unit  110  is used to receive later-described advertisement information, and for Generic Attribute Profile (GATT) communication by the short-range wireless communication unit  157 . GATT is a profile governing reading and writing (transmission/reception) of information in the Bluetooth® Low Energy standard. The communication standard of the short-range wireless communication unit  110  is not restricted to Bluetooth® Low Energy, and, for example, near field communication (NFC) or Wi-Fi Aware™ can be used. 
     The communication device  151  is the communication device according to the present embodiment. The communication device  151  includes ROM  152 , RAM  153 , a CPU  154 , a print engine  155 , a communication unit  156 , the short-range wireless communication unit  157 , and so forth. 
     The communication unit  156  includes an access point to connect to devices, such as the information processing device  101  and so forth, as an access point within the communication device  151 . This access point can connect to the communication unit  109  of the information processing device  101 . The communication unit  156  can directly communicate with the information processing device  101  by wireless communication, or can communicate via the access point  131 . As previously indicated, examples of communication standards include Wi-Fi®, Bluetooth®, and so forth. The communication unit  156  can include hardware to function as an access point, or can use software to function/operate as an access point. 
     The short-range wireless communication unit  157  is a configuration that wirelessly connects to devices such as the information processing device  101  and so forth at close distance. Bluetooth® Low Energy is used as the communication standard of the short-range wireless communication unit  157  in the present embodiment. Accordingly, the short-range wireless communication unit  157  is used to transmit later-described advertisement information to receive Bluetooth® Low Energy connection requests, and for GATT communication with the short-range wireless communication unit  110 . 
     An input interface  158  is an interface that accepts data input and operation instructions from a user via an operating unit (omitted from illustration) such as a physical keyboard or buttons, a touch panel, or the like. At least part of a later-described display unit  160  and the operating unit can be integrated so that, for example, output from a screen and accepting operations from the user are performed on the same screen. 
     An output interface  159  is an interface that performs control so that the display unit  160  can display data and notifications regarding the state of the communication device  151 . The display unit  160  includes LEDs, an LCD, or the like, and displays data and notifications of the state of the communication device  151 . A soft keyboard including numeric input keys, mode setting keys, an OK key, a cancel key, a power key, and so forth, can be provided on the display unit  160  to enable user input to be accepted via the display unit  160 . 
     The RAM  153  is made up of SRAM, DRAM, or the like, that requires a backup power source. The data in the RAM  153  can be kept by a primary battery for data backup, which is omitted from illustration. In this case, the RAM  153  can store important data, such as program control variables and the like, in a non-volatile manner. A memory area for storing settings information of the communication device  151  and management data and the like of the communication device  151  is also provided to the RAM  153 . The RAM  153  also is used as a main memory and a work memory for the CPU  154 , to serve as a reception buffer to temporarily save print information received from the information processing device  101  or the like, and to save various types of information. 
     The ROM  152  stores fixed data, such as control programs executed by the CPU  154 , data tables, OS programs, and so forth. The control programs stored in the ROM  152  in the present embodiment perform software execution control such as scheduling, task switching, interrupt processing, and so forth, under the embedded OS stored in the ROM  152 . The CPU  154  is a system control unit. The CPU  154  controls the overall communication device  151  by executing programs, and activating hardware, and so forth. 
     The print engine  155  performs image formation on a recording medium, such as paper or the like, using a recording medium such, as ink or the like, based on information saved in the RAM  153  or a print job received from the information processing device  101  or the like and outputs printing results. The print job received from the information processing device  101  or the like at this time includes a large amount of transmission data requiring high-speed communication, so reception is performed in the present embodiment using the communication unit  156  that can handle higher-speed communication than the short-range wireless communication unit  157 . 
     Memory, such as an external hard disk drive (HDD), a secure digital (SD) card, or the like, can be mounted to the communication device  151  as an optional device. Information saved in the communication device  151  can be saved in this memory. 
     The connection mode of the communication device  151  according to the present embodiment is set by later-described connection setting processing, and the communication device  151  performs communication with the information processing device by a connection arrangement based on the set connection mode. In the communication device according to the present embodiment, in a case of performing connection by infrastructure communication, an infrastructure connection mode is set as the connection mode. In a case of performing connection by direct connection, a direct connection mode is set as the connection mode. 
     The information processing device  101  operates as a master device in the present embodiment and the communication device  151  operates as a slave device. Although an example is illustrated where the information processing device  101  and communication device  151  share processing, this sharing arrangement is not seen to be limiting, and other arrangements can be used. 
     Processing for transmitting advertisement information and receiving a Bluetooth® Low Energy connection request in the Bluetooth® Low Energy standard will now be described. The short-range wireless communication unit  157  operates as a slave device in the present embodiment, so the short-range wireless communication unit  157  performs the above processing for transmitting and receiving. 
     The short-range wireless communication unit  157  performs communication using GATT communication (Bluetooth® Low Energy communication), where a 2.4 GHz frequency band is divided into 40 channels (channel 0 through 39). Of these, the 37th through 39th channels are used for transmission of advertisement information and reception of Bluetooth® Low Energy connection requests, and the 0th through 36th channels are used for data communication following Bluetooth® Low Energy connection. 
       FIG.  2    illustrates the power consumption for transmitting advertisement information using a single channel, broken down into processes. The vertical axis represents the power consumption of the short-range wireless communication unit  157  and the horizontal axis represents time. Tx 205  indicates the total amount of power consumed in processing of broadcasting advertisement information (hereinafter referred to as “transmission processing”), and Rx 206  indicates the total amount of power consumed in processing of keeping the receiver enabled to receive Bluetooth® Low Energy connection requests (hereinafter referred to as “reception processing”). 
     Transmission power  202  indicates the peak power consumption by transmission processing. Reception power  203  indicates the peak power consumption by reception processing. Microprocessor operation power  201  indicates the peak power consumption in a case where the microprocessor within the short-range wireless communication unit  157  is operating. The microprocessor operates before, during, and after Tx 205  and Rx 206  because the microprocessor needs to be active beforehand in order to execute or stop transmission/reception processing. 
     In a case where transmission of advertisement information is performed using multiple channels, the power consumption increases proportionately to the number of channels transmitting advertisement information. In a state where the short-range wireless communication unit  157  is in a power saving mode, with the microprocessor not operating, sleep power  204  is the peak power consumption of the short-range wireless communication unit  157 . The short-range wireless communication unit  157  thus performs transmission processing using a predetermined channel, and thereafter performs reception processing for a predetermined amount of time using the same channel, awaiting for transmission of a Bluetooth® Low Energy connection request from the information processing device  101 . In a case of having received a Bluetooth® Low Energy connection request from the information processing device  101 , the short-range wireless communication unit  157  establishes a Bluetooth® Low Energy connection, and performs GATT communication with the information processing device  101 . 
     The short-range wireless communication unit  157  performs advertisement information transmission processing and reception processing three times for each channel, stops the microprocessor from operating, and then goes into a power saving state for a predetermined amount, as illustrated in  FIG.  3   . A combination of advertisement information transmission processing and reception processing at a predetermined channel will be referred to as an “advertisement”, hereinafter. Also, a time cycle of transmitting advertisement information at a predetermined channel, i.e., the time cycle from transmitting advertisement information on a certain channel till transmitting the advertisement information on the same channel the next time, will be referred to as an “advertising cycle”. The number of times that advertisement is repeated from the advertisement the first time until going to the power saving state can be any number that is less than or equal to three. 
     The information processing device  101  and the communication device  151  in the present embodiment perform mutual authentication and pairing processing to realize reading and writing of data by GATT communication. GATT communication is communication where the information processing device  101  serves as a GATT client and the communication device  151  serves as a GATT server to read and write information from the information processing device  101  to the communication device  151 , using a GATT-based profile. The communication device  151  is configured such that reading and wiring of information by GATT communication is not permitted in a state where pairing has not been performed between the information processing device  101  and the communication device  151 . Thus, for example, a situation can be avoided where an unpaired information processing device  101  and communication device  151  perform communication, thus preventing information stored by the communication device  151  unintentionally being acquired by the unpaired information processing device  101 . 
     Pairing processing will now be described in detail. First, in a case where a later-described printing application is activated, and an initial screen (home screen) is displayed by the printing application on the display unit  108 , the information processing device  101  begins searching for advertisement information including certain device information. Examples of the certain device information include a universally unique identifier (UUID) or media access control (MAC) address or the like of a device (a printer or the like) corresponding to the printing application. 
     Upon receipt of the advertisement information including the certain device information, the information processing device  101  transmits a Bluetooth® Low Energy connection request (CONNECT_REQ) to the device that transmitted the advertisement information (the communication device  151  in this case), and establishes a Bluetooth® Low Energy connection between the devices. In a case where pairing with the communication device  151  has not yet completed, the information processing device  101  displays a screen on the display unit  108  prompting the user to perform pairing. 
     In a case where the user has instructed execution of pairing, the information processing device  101  transmits a pairing request to the communication device  151  using the security manager protocol (SMP) in the Bluetooth® Low Energy standard. Communication between the devices is performed by SMP until pairing is complete. Upon receiving the pairing request, the communication device  151  displays a PIN code display screen  400 , as illustrated in  FIG.  4 A , on the display unit  160 . The PIN code display screen  400  displays a PIN code  401  and a cancel button  402  to cancel the pairing processing. 
     Upon transmission of the pairing request, a PIN code input screen  410 , as illustrated in  FIG.  4 B , is displayed on the display unit  108 . The PIN code input screen  410  displays a PIN code input region  411 , an OK button  413 , and a cancel button  412 . The PIN code input region  411  is a region to accept input of the PIN code  401  by the user. The OK button  413  is a button to transmit the input PIN code  401  to the communication device  151 , and the cancel button  412  is a button to cancel the pairing processing. When the OK button  413  is pressed in a state where the PIN code  401  is input to the PIN code input region  411 , the information processing device  101  transmits information including the input PIN code  401  to the communication device  151 . The information processing device  101  determines whether the PIN code  401  included in the received information matches the PIN code  401  displayed in the PIN code display screen  400 , and if determination is made that these match, permits the information processing device  101  to pair. 
     More specifically, the communication device  151  transmits a link key created by a predetermined method based on the PIN code  401  to the information processing device  101  using SMP in the Bluetooth® Low Energy standard. Thus, the link key is stored in each of a storage region that the information processing device  101  has (ROM  104  or the like) and a storage region that the communication device  151  has (ROM  152  or the like). This completes pairing, and thereafter, Bluetooth® Low Energy communication is permitted among the devices. Once the pairing is completed, the information processing device  101  hides the PIN code display screen  400  from display, and returns to displaying the original screen. 
     After paring is complete, when the information processing device  101  transmits a GATT communication request to the communication device  151 , the link key saved in the storage region at the time of pairing processing is notified to the communication device  151 . Upon receipt of a GATT communication request, the communication device  151  compares the link key saved in the storage region at the time of pairing processing with the notified link key, and confirms whether the device issuing the GATT communication request is a device with which pairing has been completed. 
     In a case where confirmation has been made that the device has been paired with, the communication device  151  starts reading and writing of information with the information processing device  101  by GATT communication. Accordingly, once pairing processing with the communication device  151  is completed, the information processing device  101  can execute GATT communication with the communication device  151  without the user having to input the PIN code anymore. 
     Although an arrangement has been described above where the user inputs the PIN code  401  displayed in the PIN code input region  411  on the PIN code input screen  410 , this arrangement is not restrictive. For example, the PIN code  401  can be fixed, i.e., the user cannot optionally change, information that is stored in the information processing device  101  at the time of installing the later-described printing application. Thus, the PIN code  401  is provided to the communication device  151  even without user input. The timing of starting the pairing processing is not restricted to the above arrangement either, and, for example, can be a timing at which the user instructs printing via the printing application, or a timing before Bluetooth® Low Energy connection is performed in a later-described connection setting processing, or the like. 
     The processing of the communication device  151  to set a network state (connection setting processing) will now be described. This connection setting processing is processing to set the order in which the communication device  151  will be connected to other devices, such as the information processing device  101  and so forth. In the present embodiment, in a case of connecting to other devices in the above-described infrastructure connection, the infrastructure connection mode is set to the communication device  151  by the connection setting processing. In a case of connecting to other devices in the above-described direct connection, the direct connection mode is set to the communication device  151  by the connection setting processing. 
     At least two different communication standards are used for communication in the connection setting processing according to the present embodiment. A description will be provided regarding an arrangement where the short-range wireless communication unit  110  and short-range wireless communication unit  157  perform communication by Bluetooth® Low Energy in the present embodiment. Note that in the present embodiment, the short-range wireless communication unit  157  functions as an advertiser (or slave) that broadcasts later-described advertisement information, and the short-range wireless communication unit  110  functions as a scanner (or master) that receives the advertisement information. The communication unit  109  and communication unit  156  communicate by wireless LAN (Wi-Fi®) in this description. 
     The information processing device  101  uses a predetermined application stored in the ROM  104  or external storage  106  or the like to perform connection setting processing. The predetermined application is an application that sets an access point for the communication device  151  to connect to, causes the communication device  151  to print image data, document data, or the like within the information processing device  101 , and so forth, and hereinafter will be referred to as a “printing application”. The printing application can include other functions besides the function of setting an access point for the communication device  151  to connect to and printing functions. For example, the printing application can include functions to scan a document set in the communication device  151  in a case where the communication device  151  has a scanning function, functions for performing other settings of the communication device  151 , functions for confirming the state of the communication device  151 , and so forth. 
       FIG.  7    is an example of a screen displayed on the display unit  108  when the printing application is started. The user can use the communication device&#39;s  151  functions, such as printing a desired image or performing settings of the communication device  151 , via a startup screen  700 . Upon detecting that a printer setup button  703  has been pressed, the information processing device  101  starts connection setting processing. The communication device  151  transitions to a connection setting mode to perform connection setting processing regarding the communication device  151  in the present embodiment. 
     The connection setting mode is a mode that the communication device  151  is set to when a connection mode is to be set to the communication device  151 , and is set to the communication device  151  in a case where the user has performed a predetermined input at an operating unit that the communication device  151  has, or the like. Once in the connection setting mode, the communication device  151  starts transmission of advertisement information via the short-range wireless communication unit  157 . The timing at which the communication device  151  starts transmission of advertisement information is not restricted to the above-described arrangement, and can be at a timing at which the power of the communication device  151  is turned on, the timing at which a predetermined operation is performed to enable the Bluetooth® Low Energy function, or the like, for example. In this case, the connection setting processing is performed at the communication device  151 , so there the communication device  151  does not need to be set to the connection setting mode. 
       FIGS.  5 A and  5 B  is a flowchart illustrating connection setting processing that the information processing device  101  according to the present embodiment performs. The processing in the flowchart in  FIGS.  5 A and  5 B  is realized by the CPU  103  reading out a program stored in memory, such as the ROM  104  or the like, to the RAM  105  and executing the program. Note that the processing illustrated in the flowchart in  FIGS.  5 A and  5 B  is started in a case where the printer setup button  703  is pressed in a state where pairing between the information processing device  101  and communication device  151  is completed. It is also assumed that the communication device  151  has already transitioned to the connection setting mode at this time. 
     In S 501 , the CPU  103  detects reception of advertisement information issued from the communication device  151 , via the short-range wireless communication unit  110 . At this time, the CPU  103  confirms whether the advertisement type included in the received advertisement information is ADV_IND or ADV_DIRECT_IND permitting a connection request to the communication device  151 . In a case where this type of advertisement information has been received, the CPU  103  deems advertisement information to have been received. This advertisement information can be continuously emitted by the communication device  151 , or issuing can be started in a case where the communication device  151  detects a predetermined user operation to enable Bluetooth® Low Energy communication at an operating unit that the communication device  151  has, or the like. 
     In S 502 , the CPU  103  transmits a Bluetooth® Low Energy connection request to the communication device  151  via the short-range wireless communication unit  110 , establishes a Bluetooth® Low Energy connection between the short-range wireless communication unit  110  and communication device  151 , and starts GATT communication. In step S 503 , the CPU  103  acquires network information of the communication device  151  by GATT communication via the short-range wireless communication unit  110 . The network information of the communication device  151  is information indicating whether the communication unit  156  of the communication device  151  is connected to an external access point and whether the access point function within the communication device  151  is enabled (connection status information). 
     If the access point function within the communication device  151  is enabled, connection can be made between the access point function within the communication device  151  and other devices, such as the information processing device  101  (connection enabled state). The network information of the communication device  151  also, for example, includes information of the access point to which it is connected (service set identifier (SSID), MAC address, Internet Protocol (IP) address, passwords necessary for connection, and so forth). The network information of the communication device  151  can be, for example, flags indicating whether the communication unit  156  of the communication device  151  is connected to an external access point and whether the access point function within the communication device  151  is enabled. 
     In S 504 , the CPU  103  acquires the network information of the information processing device  101 . The network information of the information processing device  101  includes information of the connection status between the communication unit  109  that the information processing device  101  has and the external access point of the information processing device  101 . Specifically, the network information of the information processing device  101  includes whether the communication unit  109  is connected to an external access point, whether the communication unit  109  is connected to an internal access point in the communication device  151 , whether the communication unit  109  is not connected to an access point, and so forth. In a case where the communication unit  109  is connected to any of the access points, the network information of the information processing device  101  also includes information of the access point to which the communication unit  109  is connected (SSID, MAC address, IP address, passwords necessary for connection, and so forth). 
     In S 505 , the CPU  103  references the network information of the communication device  151  acquired in S 503 , and determines whether the connection mode of the communication device  151  has been set. Specifically, in a case where the communication unit  156  is connected to an external access point or other external devices, or the internal access point function within the communication device  151  is enabled, the CPU  103  determines that the connection mode of the communication device  151  has been set. 
     In a case where the communication unit  156  is not connected to an external access point, and the internal access point function within the communication device  151  is not enabled, the CPU  103  determines that the connection mode of the communication device  151  has not been set. The reason is that if the infrastructure connection mode is set to the communication device  151 , the communication unit  156  is connected to an external access point, and if the direct connection mode is set to the communication device  151 , the internal access point function within the communication device  151  is enabled. 
     The CPU  103  can determine whether the connection mode of the communication device  151  is set by a different method at this time. For example, in a case where the communication unit  156  is connected to an external access point, an external device other than the information processing device  101  or the communication unit  109 , the CPU  103  may determine that the connection mode of the communication device  151  is set. In a case where the communication unit  156  is not connected to any of these, the CPU  103  can determine that the connection mode of the communication device  151  is not set. The reason is that if the infrastructure connection mode is set to the communication device  151 , the communication unit  156  is connected to an external access point, and if the direct connection mode is set to the communication device  151 , the communication unit  156  is connected to an external device other than the information processing device  101  or the communication unit  109 . 
     In a case of the CPU  103  determining that the connection mode of the communication device  151  is set, the flow advances to S 506 . In a case of determining that the connection mode of the communication device  151  is not set, the flow advances to S 508 . 
     In S 506 , the CPU  103  references the network information acquired in S 503  and S 504 , and determines whether the communication unit  109  and the communication unit  156  can communicate. In a case where the communication unit  109  and the communication unit  156  are connected to the same external access point or the communication unit  109  is connected to the internal access point within the communication device  151 , the CPU  103  determines that the communication unit  109  and the communication unit  156  can communicate. In a case where the communication unit  109  and the communication unit  156  are connected to different external access points, the CPU  103  determines that the communication unit  109  and communication unit  156  cannot communicate. 
     In a case where the internal access point within the communication device  151  is enabled, but the communication unit  109  is not connected to this access point, the CPU  103  determines that the communication unit  109  and communication unit  156  cannot communicate. In a case where the CPU  103  determines that the communication unit  109  and communication unit  156  can communicate, the connection setting processing ends. In a case where “cannot communicate” is determined, the flow advances to S 507 . 
     In S 507 , the CPU  103  sets the network state so that the communication unit  109  and communication unit  156  can communicate. In a case where the communication unit  156  is connected to an external access point, the CPU  103  connects the communication unit  109  to the access point to which the communication unit  156  is connected. In a case where the internal access point within the communication device  151  is enabled, the CPU  103  connects the communication unit  109  to the internal access point within the communication device  151 . In a case where connection information necessary for connection to the access point to which connection is to be made is already stored in the storage region of the information processing device  101 , the CPU  103  uses this connection information to connect the communication unit  109  to the access point without user operations at this time. A case where connection information is already stored in the storage region of the information processing device  101  is, for example, a case where the information processing device  101  previously connected to this access point or a case where connection information is stored in the network information received in S 503 . 
     In a case where connection information necessary for connection to the access point to which connection is to be made is not stored in the storage region of the information processing device  101 , the CPU  103  displays a screen for accepting input of connection information on the display unit  108 , and accepts input of connection information from the user. A case where connection information is not already stored in the storage region of the information processing device  101  is, for example, a case where the information processing device  101  has never connected to this access point before or a case where connection information is not stored in the network information received in S 503 . 
     In a case of accepting connection information from the user, the CPU  103  connects the communication unit  109  to the access point using the input connection information. The CPU  103  can receive connection information of an access point to which the communication unit  156  is connected or connection information to connect to the internal access point within the communication device  151  from the communication device  151  by GATT communication via the short-range wireless communication unit  110 . This arrangement enables the communication unit  109  to be connected to the access point without accepting input from the user in a case where connection information necessary for connection to an access point to be connected to is not stored in the storage region of the information processing device  101  beforehand. In a case where input of connection information is necessary due to OS restrictions for example, even though where connection information necessary for connection to the access point to which connection is to be made is already stored in the storage region of the information processing device  101 , input of connection information can be accepted from the user. 
     In S 508 , the CPU  103  references the network information acquired in S 503 , and determines whether the communication unit  109  is connected to an external access point. In a case where the communication unit  109  is connected to the network via an access point, the communication unit  156  connects to the same to establish an infrastructure connection between the devices. The reason is that generally, while Internet communication over wireless LAN cannot be performed with a direction connection, Internet communication over wireless LAN can be performed if the access point relaying the communication is connected to the Internet by infrastructure connection. Another reason is that the information processing device  101  and communication device  151  can communicate with other devices connected to the access point used for relaying communication in an infrastructure connection. 
     In a case where the communication unit  109  is not connected to an access point, there is a high possibility that there is no external access point near the devices, so establishing a direct connection between the devices is desirable. Accordingly, in a case where the CPU  103  determines that the communication unit  109  is connected to an external access point, the flow advances to S 509  to confirm whether infrastructure connection can be executed between the information processing device  101  and communication device  151 . In a case where determination is made that the communication unit  109  is not connected to an external access point, the CPU  103  determines that a direct connection is appropriate for connection between the information processing device  101  and the communication device  151 , and the flow advances to S 515 . 
     In S 509 , the CPU  103  requests, by GATT communication via the short-range wireless communication unit  110 , the communication device  151  for a list of external access points that the communication unit  156  can connect to. The requested list is a list of information for identifying external access points that the communication unit  156  can connect to like, for example, the information for identifying external access points being SSIDs or the like. In S 510 , the CPU  103  acquires, from the communication device  151  by GATT communication via the short-range wireless communication unit  110 , the list of external access points that the communication unit  156  can connect to. 
     In S 511 , the CPU  103  determines whether an external access point to which the communication unit  109  is currently connected is included in the list acquired from the communication device  151  in S 510 . That is, the CPU  103  determines whether the external access point to which the communication unit  109  is currently connected is an external access point to which the communication unit  156  can connect. In a case of determining that the external access point to which the communication unit  109  is currently connected is included in the list, the CPU  103  judges that infrastructure connection is appropriate for connection of the information processing device  101  and communication device  151 , and the flow advances to S 512 . In a case of determining that the external access point to which the communication unit  109  is currently connected is not included in the list, the CPU  103  determines that direct connection is appropriate for connection of the information processing device  101  and communication device  151 , and the flow advances to S 515 . 
     In S 512 , the CPU  103  displays a screen on the display unit  108  to accept selection of whether to use the external access point that the communication unit  109  currently is connected to for the infrastructure connection between the information processing device  101  and communication device  151 , and accepts selection from the user. The CPU  103  then determines whether to use the external access point that the communication unit  109  is currently connected to for the infrastructure connection between the information processing device  101  and communication device  151 , based on the results of the accepted selection. 
     In a case of the CPU  103  determining to use the external access point that the communication unit  109  is currently connected to for the infrastructure connection between the information processing device  101  and communication device  151 , the flow advances to S 514 . In a case of the CPU  103  determining not to use the external access point that the communication unit  109  is currently connected to for the infrastructure connection between the information processing device  101  and communication device  151 , the flow advances to S 513 . 
     In S 513 , the CPU  103  prompts the user to select, from external access points to which the communication unit  156  can connect, an access point for the infrastructure connection between the information processing device  101  and communication device  151 . The CPU  103  displays a screen for the selection based on the list acquired in S 510 , and accepts selection of an access point from the user. If authentication processing such as inputting a password or the like is necessary for connection to the selected access point, the CPU  103  also accepts input of the password from the user. 
     In S 514 , the CPU  103  transmits a command for setting the communication device  151  to the infrastructure connection mode to the communication device  151  by GATT communication via the short-range wireless communication unit  110 . In a case where the processing is performed after the “Yes” determination in S 512 , the CPU  103  transmits information of the external access point to which the communication unit  109  is currently connected to the communication device  151  by GATT communication via the short-range wireless communication unit  110 . The information of the external access point to which the communication unit  109  is currently connected includes, for example, SSID information of the access point, password necessary to connect to this access point, and so forth. Connection information to connect to the external access point to which the communication unit  109  is currently connected is also stored in the storage region of the information processing device  101  at the time of connection of the communication unit  109  to this access point. 
     In a case where connection information to connect to the external access point to which the communication unit  109  is currently connected is not stored in the storage region of the information processing device  101 , the CPU  103  displays a screen on the display unit  108  for accepting input of the connection information. Input of the connection information to connect to the external access point to which the communication unit  109  is currently connected is accepted from the user, and the input information is transmitted to the communication device  151 . The CPU  103  does not have to accept input of connection information even if the connection information is not stored in the storage region of the information processing device  101  if the external access point to which the communication unit  109  currently is connected does not require password authentication. 
     In a case where the processing is performed after S 513 , the CPU  103  transmits information of the access point selected by the user in S 513  the communication device  151  by GATT communication via the short-range wireless communication unit  110 . Information of the access point selected by the user in S 513  includes, for example, the SSID of the access point, the password input in S 513 , and so forth. The processing of S 514  transitions the communication device  151  to the infrastructure connection mode. 
     In S 515 , the CPU  103  transmits a command for setting the communication device  151  to the direct connection mode to the communication device  151  by GATT communication via the short-range wireless communication unit  110 . Specifically, the CPU  103  requests the communication device  151  by GATT communication via the short-range wireless communication unit  110  to enable the access point within the communication device  151 . The processing of S 515  transitions the communication device  151  to the direct connection mode. 
     In S 516 , the CPU  103  uses the connection information to connect to the internal access point within the communication device  151  to connect the communication unit  109  to the internal access point within the communication device  151 . In a case where the CPU  103  does not have the connection information to connect to the internal access point within the communication device  151 , the CPU  103  receives it from the communication device  151  by GATT communication via the short-range wireless communication unit  110 . In a case where the connection information to connect to the internal access point within the communication device  151  is previously stored in the storage region of the information processing device  101 , the CPU  103  uses it to perform connection. 
     An arrangement can also be made where the CPU  103  displays a screen on the display unit  108  to accept user input of the connection information to connect to the internal access point within the communication device  151 , and accept input of the connection information. A configuration can also be made where the connection information to connect to the internal access point within the communication device  151  is included in the network information of the communication device  151 , and the CPU  103  references the network information acquired in S 503  to perform connection. After executing the processing in S 514 , the CPU  103  ends the connection setting processing. In a case where the connection setting processing ends, the CPU  103  disconnects the Bluetooth® Lowe Energy connection between the short-range wireless communication unit  110  and the communication device  151 . 
     After the processing in  FIGS.  5 A and  5 B  ends, and connection with the communication device  151  has been established by the connection form in accordance with the connection mode that the communication device  151  has been set to, the information processing device  101  can transmit jobs to the communication device  151  via the established connection. For example, the information processing device  101  can display a screen to select an image to be printed on the display unit  108 , and in a case where selection of an image and an instruction to execute printing have been accepted from the user, a print job is generated and transmitted to the communication device  151  via the established connection. Accordingly, the information processing device  101  can cause the communication device  151  to execute printing. 
       FIG.  8    is a flowchart illustrating connection setting processing executed by the communication device  151  according to the present embodiment. The processing illustrated in the flowchart in  FIG.  8    is realized by the CPU  154  reading out a program stored in memory, such as the ROM  152  or the like, to the RAM  153  and executing the program. Processing illustrated in the flowchart in  FIG.  8    is started upon transition to the connection setting mode in a state where pairing between the information processing device  101  and the communication device  151  has completed. 
     In S 801 , the CPU  154  enters an advertising state, which is a state where advertisement information is broadcast by the short-range wireless communication unit  157  every predetermined time period. The term “broadcast” refers to transmitting information over a certain range, without specifying a target of the transmission of information. 
     Next, in S 802 , the CPU  154  determines whether a Bluetooth® Low Energy connection request has been received from the information processing device  101  via the short-range wireless communication unit  157 . In a case where the short-range wireless communication unit  157  has received a Bluetooth® Low Energy connection request, the CPU  154  performs the processing in S 804 . In a case where the short-range wireless communication unit  157  has not received a Bluetooth® Low Energy connection request, the CPU  154  performs the processing in S 803  to determine whether a predetermined amount of time has elapsed after having transitioned to the connection setting mode (whether timed out). In a case where the process has not timed out, the CPU  154  repeats the processing of S 802 . In a case that the process has timed out, the CPU  154  ends the connection setting processing. 
     In S 804 , the CPU  154  temporarily stops transmission of advertisement information via the short-range wireless communication unit  157  to establish a Bluetooth® Low Energy connection and perform GATT communication. The reason is that the short-range wireless communication unit  157  cannot establish a Bluetooth® Lowe Energy connection and transmit advertisement information at the same time. In a case where the short-range wireless communication unit  157  can establish a Bluetooth® Low Energy connection and transmission of advertisement information at the same time, this processing does not have to be executed. That is, the CPU  154  can continue transmission of advertisement information via the short-range wireless communication unit  157 . 
     In S 805 , the CPU  154  then establishes the Bluetooth® Low Energy connection between the short-range wireless communication unit  157  and the information processing device  101 , and starts GATT communication via the short-range wireless communication unit  157 . In S 806 , the CPU  154  transmits the network information of the communication device  151  to the information processing device  101  by GATT communication via the short-range wireless communication unit  157 . As previously described, if an arrangement has been made where the network information of the communication device  151  is included in the advertisement information emitted from the short-range wireless communication unit  157 , this processing is not necessary. 
     Next, in S 807 , the CPU  154  determines whether a request for a list of external access points to which the communication unit  156  can connect has been received from the information processing device  101  by GATT communication via the short-range wireless communication unit  157 . In a case of the CPU  154  determining that a request for the list has been received, the flow advances to S 808 . In a case it is determined that a request for the list has not been received, the flow advances to S 809 . The CPU  154  can wait a predetermined amount of time between S 806  and S 807 , taking into consideration the amount of time required for the processing performed by the information processing device  101 . 
     In S 808 , the CPU  154  searches for external access points that the communication unit  156  can connect to, and generates a list of external access points that the communication unit  156  can connect to. The CPU  154  executes the search for external access points that the communication unit  156  can connect to by detecting beacons based on Wi-Fi® communication using the communication unit  156 . After generating the list, the CPU  154  transmits the generated list to the information processing device  101  by GATT communication via the short-range wireless communication unit  157 . If a list of external access points that the communication unit  156  can connect to has previously been generated, the CPU  154  can transmit the already-generated list to the information processing device  101  without searching for the external access points that the communication unit  156  can connect to. 
     In S 809 , the CPU  154  determines whether a command for setting the communication device  151  to the communication mode has been received from the information processing device  101  by GATT communication via the short-range wireless communication unit  157 . In a case where it is determined that the command has been received, the CPU  154  performs the processing in S 810 . In a case where it is determined that the command has not been received, the CPU  154  performs the processing of S 811  to determine whether a predetermined amount of time has elapsed after having started GATT communication (whether timed out). In a case where it is determined that the process has not timed out, the CPU  154  repeats the processing in S 809 . In a case where it is determined that the process has timed out, the CPU  154  performs the processing in S 812 . 
     In S 810 , the CPU  154  sets the connection mode of the communication device  151  based on the command that has been received. In a case where the received command is a command to set the communication device  151  to the infrastructure connection mode, the CPU  154  transitions the communication device  151  to the infrastructure connection mode. Specifically, the CPU  154  registers the access point (access point  131  in this case), indicated by the SSID stored in the received command, as the connection target of the communication device  151 . After registration of the access point, the CPU  154  uses the connection information stored in the command to connect the communication unit  156  to the access point  131 . 
     In a case where connection is successful, the infrastructure connection between the information processing device  101  and the communication device  151  via the access point  131  is established. Setting the communication device  151  to the infrastructure connection mode means that communication can also be performed with other information processing devices subsequently connected to the access point  131 . The CPU  154  can notify the information processing device  101  by GATT communication whether connection to the access point  131  has been successful. A configuration can be made where, in a case of receiving a notification from the communication device  151  that connection to the access point has failed, the information processing device  101  re-executes the connection setting processing. 
     In a case where the received command is a command to set the communication device  151  to the direct connection mode, the CPU  154  transitions the communication device  151  to the direct connection mode. Specifically, the CPU  154  sets the internal access point function within the communication device  151  to be enabled, so as to be in a state where the information processing device  101  can connect to the internal access point within the communication device  151 . In a case where a connection request to the internal access point within the communication device  151  is accepted from the information processing device  101 , the CPU  154  permits this, and the information processing device  101  is thus in a communicable state via the communication unit  156 . Setting the communication device  151  to the direct connection mode enables the internal access point within the communication device  151 , so even after the connection with the information processing device  101  is disengaged, communication can be performed with other devices by performing a direct connection with those devices. 
     While an arrangement has been described where the internal access point within the communication device  151  is enabled in a case where the direct connection mode is set, this is not restrictive. For example, in a case of transmitting the communication device  151  to the direct connection mode, the CPU  154  can execute sequence control to perform connection by Wi-Fi Direct®. In this case, the CPU  154  performs negotiation with the information processing device  101 , and determines to enable the internal access point within the communication device  151  or to connect the communication unit  156  to the internal access point within the information processing device  101 , based on the results of the negotiation. In a case of deciding to enable the internal access point within the communication device  151 , this access point is enabled, and connection between this access point and the communication unit  109  is established. In a case of deciding to connect the communication unit  156  to the internal access point within the information processing device  101 , connection between this access point and the communication unit  156  is established. 
     In S 812 , the CPU  154  disengages the Bluetooth® Low Energy connection between the short-range wireless communication unit  157  and the information processing device  101 , and ends GATT communication. The short-range wireless communication unit  157  resumes transmission of advertisement information in a case where the Bluetooth® Low Energy connection is disengaged. 
     According to this arrangement, the information processing device  101  can set the connection mode of the communication device  151 , and can connect to the communication device  151  by the connection form in accordance with the connection mode that has been set. 
     Also, in the present embodiment, in a case where the connection mode of the communication device  151  has been set, the information processing device  101  connects with the communication device  151  by a connection form in accordance with the already-set connection mode, rather than setting the connection mode of the communication device  151 . The information processing device  101  automatically decides whether to perform settings of the connection mode of the communication device  151  based on network information acquired from the communication device  151 . Accordingly, in a case where the connection mode of the communication device  151  has been set, the information processing device  101  can omit the setting processing of the connection mode of the communication device  151 , thereby reducing the load on the information processing device  101 . This can also suppress a situation where another information processing device, which previously set the connection mode, cannot communicate with the communication device  151  due to the connection mode of the communication device  151  being changed. 
     There can also be usage cases where the user wants to change the connection mode of the communication device  151  due to, for example, a new external access point having been installed in the network environment of the communication device  151 , or the like. Accordingly, the communication device  151  can have an initialization function for resetting the connection mode that is set to return to the state where no connection mode is set. The user can change the connection mode of the communication device  151  to that corresponding to a new network environment after executing the initialization function, and then the above-described connection mode setting processing. 
     The details of connection setting processing are not restricted to the forms described above. For example, in S 501 , the CPU  103  is described as receiving advertisement information in a case of receiving an advertisement of a type where a connection request to the communication device  151  is permitted, but this is not restrictive. For example, in S 501  the CPU  103  can confirm detailed data contained in advertisement information other than the advertisement type. Specifically, in a case where information is included in the received advertisement information that the network status of the communication device  151  is not set, the CPU  103  can advance to S 502 . In this case, the CPU  103  does not have to deem the advertisement information as having been received in a case where the received advertisement information does not include information that the network status of the communication device  151  is not set. 
     There are also cases where the information processing device  101  receives advertisement information from multiple communication devices. In these cases, the CPU  103  detects reception of multiple sets of advertisement information that match the above conditions in S 501 . The CPU  103  can then display a screen illustrating a list of multiple communication devices corresponding to the multiple sets of advertisement information that have been received, such as illustrated in  FIG.  6   , after S 501 , and have the user select the communication device that the communication setting processing is to be performed on. 
       FIG.  6    illustrates an example of a screen displayed in a case where advertisement information has been received from three communication devices. In the screen illustrated in  FIG.  6   , the device names of each of the communication devices, and the device addresses (BD_ADDR) of the short-range wireless communication units that the communication devices each have, are shown so that the user can identify the communication devices. This information is included in the advertisement information transmitted from the respective communication devices. 
     The CPU  103  has been described as acquiring network information of the communication device  151  in S 503  by GATT communication with the communication device  151 , but this is not restrictive. For example, an arrangement can be made where the network information of the communication device  151  is included in the advertisement information transmitted by the communication device  151 , with the received advertisement information being referenced in the processing of referencing the network information of the communication device  151 . In this case, the processing of S 503  becomes unnecessary. 
     The CPU  103  has also been described in S 509  and S 510  as acquiring a list of external access points which the communication device  151  can connect to from the communication device  151 , while GATT communication between the information processing device  101  and the communication device  151  remains established, but this is not restrictive. For example, in S 509  the CPU  103  can temporarily release the Bluetooth® Low Energy connection after having requested the communication device  151  for a list of external access points that the communication unit  156  can connect to. In this case, after releasing the Bluetooth® Low Energy connection, the CPU  103  waits to receive advertisement information via the short-range wireless communication unit  110 , including information indicating that generating of the list of external access points that the communication unit  156  can connect to, has been completed. 
     In a case where the advertisement information is received via the short-range wireless communication unit  110 , the CPU  103  re-establishes the Bluetooth® Low Energy connection, and acquires the list of external access points that the communication unit  156  can connect to by GATT communication via the short-range wireless communication unit  110 . This is to secure as much time as possible for devices other than the information processing device  101  to be able to receive the advertisement information transmitted from the short-range wireless communication unit  157 . 
     In a case of having received a request for the list of external access points that the communication unit  156  can connect to, the communication device  151  starts to generate the list, but there are cases where generating this list takes time to complete. The short-range wireless communication unit  157  cannot transmit advertisement information while the Bluetooth® Low Energy connection is established. So, in the state where the Bluetooth® Low Energy connection is established, devices other than the information processing device  101  cannot receive advertisement information transmitted by the short-range wireless communication unit  157  as long as the communication device  151  is generating the list of external access points the communication unit  156  can connect to. Accordingly, temporarily releasing the Bluetooth® Low Energy connection, as described above, enables devices other than the information processing device  101  to receive the advertisement information being transmitted by the short-range wireless communication unit  157  while the communication device  151  is generating the list of external access points. 
     An arrangement can also be made where the short-range wireless communication unit  157  stops advertising while the communication device  151  is generating the list of external access points, even though the Bluetooth® Low Energy connection is released. According to this arrangement, devices other than the information processing device  101  cannot receive the advertisement information transmitted from the short-range wireless communication unit  157 , but electric power consumed by the short-range wireless communication unit  157  can be reduced. 
     In a case where determination is made in the determination in S 511  that the external access point to which the communication unit  109  is currently connected is not included in the list, the CPU  103  sets the communication device  151  to the direct connection mode, but this is not restrictive. For example, even in a case where determination is made that the external access point to which the communication unit  109  is currently connected is not included in the list, the CPU  103  can set the infrastructure connection mode. In this case, if determination is made that the external access point to which the communication unit  109  is currently connected is not included in the list, the CPU  103  displays a list of external access points to which the communication unit  156  can connect on the display unit  108  for the user to select one from the list. 
     The CPU  103  then transmits information of the external access point selected by the user to the communication device  151  by GATT communication via the short-range wireless communication unit  110 , as a command for setting the communication device  151  to the infrastructure connection mode. The CPU  103  can display on the display unit  108  a screen for accepting input of connection information for connecting to the external access point that the user has selected to accept input of connection information from the user. In this case, the CPU  103  stores the connection information that has been input, and transmits a command to set the communication device  151  to the infrastructure connection mode. Thereafter, the CPU  103  switches the connection destination of the communication unit  109  to the external access point that the user has selected. 
     The CPU  103  can use the connection information input as described above at this time. This enables the CPU  103  to set the communication device  151  to the infrastructure connection mode, while also communicating with the communication device  151  via the communication unit  109 . 
     In a case where determination is made that the external access point to which the communication unit  109  is currently connected is not included in the list, the CPU  103  can enable the user to select which of the infrastructure connection mode and the direct connection mode to set. In this case, the CPU  103  displays on the display unit  108  a list of external access points to which the communication unit  156  can connect, and a button for setting the direct connection mode. 
     In a case where the user selects one of the access points from the list, the CPU  103  sets the communication device  151  to the infrastructure connection mode where connection is performed via the selected access point. In a case where the button for setting the direct connection mode is selected, the CPU  103  sets the communication device  151  to the direct connection mode. 
     Setting processing regarding the connection destination of the communication unit  109  is performed using communication by the short-range wireless communication unit  110  in the present embodiment. Accordingly, the information processing device  101  can perform setting processing regarding the connection destination of the communication unit  109  without changing the connection destination of the communication unit  109 . 
     While a description has been provided regarding an arrangement in the above-described embodiment where the information processing device  101  connects to an internal access point within the communication device  151  for direct connection, this is not restrictive. An arrangement can be made where the communication device  151  connects to an internal access point within the information processing device  101 . In this case, the information processing device  101  transmits connection setting information containing the SSID and password for the internal access point within the information processing device  101  to the communication device  151  by GATT communication via the short-range wireless communication unit  110 . The communication device  151  uses the SSID and password for the internal access point within the information processing device  101  contained in the connection setting information that has been received to connect the communication unit  156  and the internal access point within the information processing device  101 . 
     While a description has been provided regarding an arrangement in the above-described embodiment where the two types of connection modes, infrastructure connection mode and direct connection mode, can be set by the connection setting processing, this is not restrictive. For example, the present embodiment can be applied to a device that is capable of just setting one of the infrastructure connection mode and direct connection mode. In this case, it is sufficient for the CPU  103  to determine in S 505  whether the communication device  151  has been set to a settable connection mode. More specifically, if the settable connection mode is the direct connection mode, it is sufficient for the CPU  103  to determine whether the internal access point function within the communication device  151  is enabled and whether the communication unit  156  is connected to an external device other than the information processing device  101 , or the communication unit  109 . 
     If the settable connection mode is the infrastructure connection mode, it is sufficient for the CPU  103  to determine whether the communication unit  156  is connected to an external access point. In a case where it is determined in S 505  that the connection mode of the communication device  151  has not been set, the CPU  103  performs processing to set the communication device  151  to a settable connection mode, regardless of the connection form of the communication unit  109 . More specifically, in a case where the settable connection mode is the direct connection mode, following determination that the connection mode of the communication device  151  has not been set in S 505 , the CPU  103  skips the processing in S 508 , and performs the processing of S 515  and thereafter. In a case where the settable connection mode is the infrastructure connection mode, following a determination in S 505  that the connection mode of the communication device  151  has not been set, the CPU  103  skips the processing in S 508 , and performs the processing of S 509  and thereafter. 
     While a description has been provided regarding an arrangement in the above-described embodiment where the connection mode that the communication device  151  is set to is decided in accordance with whether the communication unit  109  is connected to an external access point and whether the communication device  151  is capable of connecting to the access point to which the communication unit  109  is connected, this is not restrictive. For example, an arrangement can be made where one mode that a user selects from multiple types of connection modes is singularly set. In this case, following determination that the connection mode of the communication device  151  has not been set in S 505 , the CPU  103  performs processing to move the state of the communication device  151  to the connection mode selected by the user, regardless of the connection form of the communication unit  109 . 
     More specifically, in a case where the connection mode selected by the user is the direct connection mode, following a determination in S 505  that the connection mode of the communication device  151  has not been set, the CPU  103  skips the processing in S 508 , and performs the processing of S 515  and thereafter. In a case where the connection mode selected by the user is the infrastructure connection mode, following a determination in S 505  that the connection mode of the communication device  151  has not been set, the CPU  103  skips the processing in S 508 , and performs the processing of S 509  and thereafter. 
     In a case where advertisement information has been received in S 501 , for example, the CPU  103  can reference device information contained in the received advertisement information and determine whether the device that transmitted the advertisement information that has been received is a registered device. A registered device is a device registered by the information processing device  101  as a device that performs communication using the printing application. 
     In a case of registering a device, the CPU  103  saves device information of the device being registered in a memory such as the ROM  104  or the like. The CPU  103  determines whether the device that transmitted the received advertisement information is a registered device by comparing the saved information with the device information contained in the received advertisement information. 
     In a case where the CPU  103  determines that the device that transmitted the received advertisement information is a registered device, the processing of S 506  and thereafter is performed. The reason is the connection mode has most likely previously been set to the registered device since the device needs to be connected to the information processing device  101  in order for device registration to be performed. Accordingly, in a case where the device that transmitted the received advertisement information is a registered device, the CPU  103  can omit the processing of establishing a Bluetooth® Low Energy connection and the processing of executing GATT communication. 
     In a case where the result of determination in S 506  is No, the CPU  103  establishes the Bluetooth® Low Energy connection and acquires the network status of the communication device  151 . In a case where the CPU  103  determines that the device that transmitted the received advertisement information is not a registered device, the processing of S 502  and thereafter is performed.
