     Referring to  FIG.  1   , the electronic device  101  in the network environment  100  may communicate with an electronic device  102  via a first network  198  (e.g., a short-range wireless communication network), or at least one of an electronic device  104  or a server  108  via a second network  199  (e.g., a long-range wireless communication network). According to an embodiment, the electronic device  101  may communicate with the electronic device  104  via the server  108 .

     The processor  120  may execute, for example, software (e.g., a program  140 ) to control at least one other component (e.g., a hardware or software component) of the electronic device  101  coupled with the processor  120 , and may perform various data processing or computation. According to one embodiment, as at least part of the data processing or computation, the processor  120  may store a command or data received from another component (e.g., the sensor module  176  or the communication module  190 ) in volatile memory  132 , process the command or the data stored in the volatile memory  132 , and store resulting data in non-volatile memory  134 .

     The auxiliary processor  123  may control at least some of functions or states related to at least one component (e.g., the display module  160 , the sensor module  176 , or the communication module  190 ) among the components of the electronic device  101 , instead of the main processor  121  while the main processor  121  is in an inactive (e.g., sleep) state, or together with the main processor  121  while the main processor  121  is in an active state (e.g., executing an application). According to an embodiment, the auxiliary processor  123  (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., the camera module  180  or the communication module  190 ) functionally related to the auxiliary processor  123 . According to an embodiment, the auxiliary processor  123  (e.g., the neural processing unit) may include a hardware structure specified for artificial intelligence model processing.

The display module  160  may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. According to an embodiment, the display module  160  may include a touch sensor adapted to detect a touch, or a pressure sensor adapted to measure the intensity of force incurred by the touch. 
     The audio module  170  may convert a sound into an electrical signal and vice versa. According to an embodiment, the audio module  170  may obtain the sound via the input module  150 , or output the sound via the sound output module  155  or a headphone of an external electronic device (e.g., an electronic device  102 ) directly (e.g., wiredly) or wirelessly coupled with the electronic device  101 . 
     The sensor module  176  may detect an operational state (e.g., power or temperature) of the electronic device  101  or an environmental state (e.g., a state of a user) external to the electronic device  101 , and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment, the sensor module  176  may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor. 
     The interface  177  may support one or more specified protocols to be used for the electronic device  101  to be coupled with the external electronic device (e.g., the electronic device  102 ) directly (e.g., wiredly) or wirelessly. According to an embodiment, the interface  177  may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface. 
     A connecting terminal  178  may include a connector via which the electronic device  101  may be physically connected with the external electronic device (e.g., the electronic device  102 ). According to an embodiment, the connecting terminal  178  may include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector). 
     The haptic module  179  may convert an electrical signal into a mechanical stimulus (e.g., a vibration or a movement) or electrical stimulus which may be recognized by a user via his tactile sensation or kinesthetic sensation. According to an embodiment, the haptic module  179  may include, for example, a motor, a piezoelectric element, or an electric stimulator. 
     The camera module  180  may capture a still image or moving images. According to an embodiment, the camera module  180  may include one or more lenses, image sensors, image signal processors, or flashes. 
     The power management module  188  may manage power supplied to the electronic device  101 . According to one embodiment, the power management module  188  may be implemented as at least part of, for example, a power management integrated circuit (PMIC). 
     The battery  189  may supply power to at least one component of the electronic device  101 . According to an embodiment, the battery  189  may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell. 
     The communication module  190  may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device  101  and the external electronic device (e.g., the electronic device  102 , the electronic device  104 , or the server  108 ) and performing communication via the established communication channel. The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module  190  may include a wireless communication module  192  (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module  194  (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network  198  (e.g., a short-range communication network, such as Bluetooth™ wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network  199  (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module  192  may identify and authenticate the electronic device  101  in a communication network, such as the first network  198  or the second network  199 , using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module  196 . 
     The wireless communication module  192  may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module  192  may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module  192  may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module  192  may support various requirements specified in the electronic device  101 , an external electronic device (e.g., the electronic device  104 ), or a network system (e.g., the second network  199 ). According to an embodiment, the wireless communication module  192  may support a peak data rate (e.g., 20 Gbps or more) for implementing eMBB, loss coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or a round trip of lms or less) for implementing URLLC. 
     The antenna module  197  may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device  101 . According to an embodiment, the antenna module  197  may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the antenna module  197  may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network  198  or the second network  199 , may be selected, for example, by the communication module  190  (e.g., the wireless communication module  192 ) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module  190  and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module  197 . 
     According to various embodiments, the antenna module  197  may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band. 
     At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)). 
     According to an embodiment, commands or data may be transmitted or received between the electronic device  101  and the external electronic device  104  via the server  108  coupled with the second network  199 . Each of the electronic devices  102  or  104  may be a device of a same type as, or a different type, from the electronic device  101 . According to an embodiment, all or some of operations to be executed at the electronic device  101  may be executed at one or more of the external electronic devices  102 ,  104 , or  108 . For example, if the electronic device  101  should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device  101 , instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device  101 . The electronic device  101  may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device  101  may provide ultra low-latency services using, e.g., distributed computing or mobile edge computing. In another embodiment, the external electronic device  104  may include an internet-of-things (IoT) device. The server  108  may be an intelligent server using machine learning and/or a neural network. According to an embodiment, the external electronic device  104  or the server  108  may be included in the second network  199 . The electronic device  101  may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology. 
     The Bluetooth device may be controlled through an electronic device that is connected 1:1 and has completed pairing. For example, in the case of a Bluetooth device for media play, media control is possible through only the electronic device in which the pairing has been completed. 
     When another electronic device attempts to control the Bluetooth device paired with the electronic device, an inconvenience of disconnecting the existing pairing connection between the Bluetooth device and the electronic device and performing pairing again between the other electronic device and the Bluetooth device is caused. 
       FIG.  2    illustrates an environment including an electronic device, a first external electronic device, and a second external electronic device according to an embodiment of the disclosure. 
     Referring to  FIG.  2   , a wireless environment  200  may include the electronic device  101 , a first external electronic device  210 , and a second external electronic device  220 . The electronic device  101  may correspond to the electronic device  101  of  FIG.  1   . 
     According to an embodiment of the disclosure, the electronic device  101  may communicate with the first external electronic device  210 . The first external electronic device  210  may be a device capable of providing media content. For example, the first external electronic device  210  may correspond to a Bluetooth speaker and an audio video navigation (AVN) device in a vehicle. The communication may refer to a connectionless communication based on a BLE. For example, the electronic device  101  may transmit an advertising packet including a control command for media content to the first external electronic device  210 , before transmitting an advertising packet including a protocol data unit (PDU) of CONNECT_REQ to the first external electronic device  210 . The media content may refer to multimedia content playable in the first external electronic device  210 . The media content may at least include a song, a video, and a picture. The control command may include a command for media content controlled by the first external electronic device  210 . For example, the control command may correspond to a command for indicating any one of a volume up, a volume down, play next song, play previous song, play current song, and pause current song for media content. For another example, the electronic device  101  may receive an advertising packet indicating a result of a control command for the media content from the first external electronic device  210 . The advertising packet may include information for indicating whether the control command for the media content is performed by the first external electronic device  210  or the first external electronic device  210  rejects the control command. 
     According to an embodiment of the disclosure, the electronic device  101  may transmit and receive a BLE packet to and from the second external electronic device  220 . The second external electronic device  220  may correspond to an indoor positioning system (IPS) device for identifying a position of the external device (e.g., the electronic device  101 ) in an indoor area. The BLE packet may correspond to an advertising packet. For example, the BLE packet may be an advertising packet corresponding to a protocol data unit (PDU) of advertising extended indications (ADV_EXT_IND). The second external electronic device  220  may identify the position of the electronic device  101  in response to receiving the advertising packet from the electronic device  101 . For example, the second external electronic device  220  may identify whether the electronic device  101  is included in a predetermined area from the second external electronic device  220  based on the advertising packet. 
     According to an embodiment of the disclosure, the first external electronic device  210  may communicate with the second external electronic device  220 . The communication may be a BLE communication. For example, the first external electronic device  210  may transmit a data packet of a first signal to the second external electronic device  220 . The first signal may include information for determining whether to perform a control command received from the electronic device  101  based on the position of the electronic device  101 . The information for determining whether to perform the control command received from the electronic device  101  may be referred to as Bluetooth authentication information. The first signal may include information requesting to identify whether the electronic device  101  is included within a predetermined area from the second external electronic device  220 . The second external electronic device  220  may transmit a data packet of the second signal to the first external electronic device  210  in response to the first signal. The second signal may include information indicating whether the electronic device  101  is included within a predetermined area from the second external electronic device  220 . In other words, the second signal may include information indicating a Bluetooth authentication result of the electronic device  101 . For example, when the electronic device  101  is identified as being located outside the predetermined area, the second external electronic device  220  may transmit the second signal indicating a failure of the Bluetooth authentication to the first external electronic device  210 . For another example, when the electronic device  101  is identified as being located within the predetermined area, the second external electronic device  220  may transmit the second signal indicating a success of the Bluetooth authentication to the first external electronic device  210 . 
     According to an embodiment of the disclosure, the second external electronic device  220  may identify the position of the electronic device  101 . The second external electronic device  220  may receive advertising packets corresponding to a protocol data unit (PDU) of the ADV_EXT_IND from the electronic device  101 , and identify the position of the electronic device  101  based on the received times and the received strengths at which the packets are received. The second external electronic device  220  may determine whether the electronic device  101  is Bluetooth authenticated based on the identified position of the electronic device  101 . For example, when the position of the identified electronic device  101  is identified within the predetermined area, the second external electronic device  220  may identify the electronic device  101  as a Bluetooth authenticated device. For another example, when the position of the identified electronic device  101  is identified outside the predetermined area, the second external electronic device  220  may identify the electronic device  101  as a Bluetooth unauthenticated device.

     Referring to  FIG.  3   , the first external electronic device  210  may include a processor  310 , a memory  320 , a communication circuit  330 , a speaker  340 , and a display  350 . 
     The processor  310  within the first external electronic device  210  may be operatively coupled to the memory  320  configured to store instructions. The processor  310  within the first external electronic device  210  may be operatively coupled to the communication circuit  330  used for communication with an external electronic device (e.g., electronic device  101 ). 
     According to an embodiment of the disclosure, the processor  310  within the first external electronic device  210  may broadcast an advertising packet to establish a communication link between the first external electronic device  210  and an external electronic device (e.g., the electronic device  101  and/or the second external electronic device  220 ). For example, the advertising packet may be used by the electronic device  101  and/or the second external electronic device  220  to scan the first external electronic device  210 . The PDU of the advertising packet broadcast may correspond to ADV_IND. 
     According to an embodiment of the disclosure, the processor  310  within the first external electronic device  210  may establish a communication connection with the second external electronic device  220  through the communication circuit  330 . For example, the first external electronic device  210  may establish a communication connection with the second external electronic device  220  by receiving an advertising packet including a PDU of CONNECT_REQ from the second external electronic device  220 . 
     According to an embodiment of the disclosure, the processor  310  within the first external electronic device  210  may receive an advertising packet including a control command from the electronic device  101  through the communication circuit  330 . The control command may include a command for media content playable in the first external electronic device  210 . For example, the control command may correspond to a command for indicating any one of a volume up, a volume down, play next song, play previous song, play current song, and pause current song for media content. 
     According to an embodiment of the disclosure, the processor  310  within the first external electronic device  210  may identify whether to process the control command in response to an advertising packet including the control command. Since the first external electronic device  210  is a step before establishing a Bluetooth connection with the electronic device  101 , the first external electronic device  210  may identify processing of the control command based on whether the electronic device  101  is Bluetooth authenticated. For example, when the electronic device  101  that has transmitted the control command is a Bluetooth authenticated device, the processor  310  may control media content according to the control command. When the electronic device  101  that has transmitted the control command is a Bluetooth unauthenticated device, the first external electronic device  210  may bypass the control command. 
     According to an embodiment of the disclosure, the processor  310  within the first external electronic device  210  may transmit a first signal requesting Bluetooth authentication to the second external electronic device  220  through the communication circuit  330 . As described above, since the first external electronic device  210  has established a Bluetooth connection with the second external electronic device  220 , the first signal may correspond to a data packet. The first signal may at least include information for requesting Bluetooth authentication of the electronic device  101 . For example, the first signal may include a media access control (MAC) address for specifying the electronic device  101 . 
     According to an embodiment of the disclosure, the processor  310  within the first external electronic device  210  may receive a second signal including a Bluetooth authentication result from the second external electronic device  220  through the communication circuit  330 . Since the first external electronic device  210  has established a Bluetooth connection with the second external electronic device  220 , the second signal may correspond to a data packet. The second signal may at least include information capable of indicating whether the electronic device  101  is Bluetooth authenticated. For example, the second signal may include 1 bit. For example, when the electronic device  101  is a Bluetooth authenticated device by being included in a predetermined area from the second external electronic device  220 , the 1 bit may correspond to a logic value of 1. For example, when the electronic device  101  is a Bluetooth unauthenticated device by being included outside the predetermined area from the second external electronic device  220 , the 1 bit may correspond to a logic value of 0. 
     According to an embodiment of the disclosure, the processor  310  within the first external electronic device  210  may identify whether the control command is performed based on the second signal and broadcast an advertising packet indicating a result of the execution. For example, when the electronic device  101  is a Bluetooth unauthenticated device, the processor  310  may discard the control command and broadcast the advertising packet including information indicating the discard. For another example, when the electronic device  101  is a Bluetooth authenticated device, the processor  310  may perform the control command and broadcast the advertising packet including information indicating the execution. The electronic device  101  may identify whether to perform a control command on the media content received from the first external electronic device  210  by receiving the advertising packet. 
     According to an embodiment of the disclosure, the processor  310  within the first external electronic device  210  may provide media content. For example, the processor  310  may output an audio signal of the media content through the speaker  340 , and may display a visual object of the media content through the display  350 . According to various embodiments of the disclosure, the media content may be received from another electronic device. For example, the first external electronic device  210  may establish a Bluetooth connection with the other electronic device different from the electronic device  101 . For example, the other electronic device may correspond to a device that most recently completed a Bluetooth connection with the first external electronic device  210 .

For example, the second signal may include information indicating whether a device (e.g., electronic device  101 ) corresponding to a MAC address included in the first signal is included in a predetermined area from the second external electronic device  220 . When the electronic device  101  is included in the predetermined area, the processor  410  may identify the electronic device  101  as a Bluetooth authenticated device and transmit a second signal including information indicating the identification to the first external electronic device  210 . When the electronic device  101  is not included in the predetermined area, the processor  410  may identify the electronic device  101  as a Bluetooth unauthenticated device and transmit a second signal including information indicating the identification to the first external electronic device  210 . 
     According to an embodiment of the disclosure, the memory  420  may store the MAC address of the Bluetooth authenticated device. The second external electronic device  220  may receive advertising packets for identifying direction from the electronic device  101  through the communication circuit  430 .

The processor  410  may identify received strengths of the advertising packet of the ADV_EXT_IND received through the first antenna  441  to the fourth antennas  444 . For example, the received strength of the advertising packet measured by the first antenna  441  may be the first strength. The processor  410  may estimate a distance at which the electronic device  101  is spaced apart from the first antenna  441  based on the first strength. For example, the received strength of the advertising packet measured by the second antenna  442  may be the second strength. The processor  410  may estimate a distance at which the electronic device  101  is spaced apart from the second antenna  442  based on the second strength. For example, the received strength of the advertising packet measured by the third antenna  443  may be the third strength. The processor  410  may estimate a distance at which the electronic device  101  is spaced apart from the third antenna  443  based on the third strength. For example, the received strength of the advertising packet measured by the fourth antenna  444  may be the fourth strength. The processor  410  may estimate a distance at which the electronic device  101  is spaced apart from the fourth antenna  444  based on the fourth strength. The processor  410  may identify an approximate position of the electronic device  101  based on the first strength to fourth strength. The processor  410  may form a circle by a distance estimated from each of the first antenna  441  to the fourth antennas, and identify that the electronic device  101  is located in an area in which four circles are common. Referring to  FIG.  4 B , the first antenna  441  to the fourth antenna  444  may form an area  440 . The area  440  may be referred to in various terms including an indoor positioning system (IPS) area, an authentication area, and a security area. The second external electronic device  220  may identify the electronic device  101  as a Bluetooth authenticated device in response to identifying that the electronic device  101  is located within the area  440 . In other words, when the electronic device  101  is located in the area  440 , the electronic device  101  may control media content of the first external electronic device  210  without exchanging advertising packets of CONNECT_REQ with the first external electronic device  210 .

For example, the advertising packets broadcasted in operation  510  may include a PDU of ADV_IND. 
     In operation  515 , the electronic device  101  may perform a scan for searching for a Bluetooth-connectable device. The electronic device  101  may perform a scan to identify an external device (e.g., the first external electronic device  210 ) at predetermined intervals. In operation  515 , the electronic device  101  may receive advertising packets broadcasted from the first external electronic device  210  while scanning.

For example, in response to identifying the first external electronic device  210  in operation  515 , the electronic device  101  may provide a pop-up notification to a user through a display (e.g., the display module  160  of  FIG.  1   ). The pop-up notification may include a visual object indicating that the first external electronic device  210  is identified near the electronic device  101  and media played in the first external electronic device  210  may be controlled. For another example, the electronic device  101  may execute a predetermined application in response to the identification of an external device (e.g., a first external electronic device  210 ) providing media content. The predetermined application may be configured to display a user interface for media control of an external device (e.g., a first external electronic device  210 ) identified at a short distance of the electronic device  101 . The electronic device  101  may identify the occurrence of the media control event in response to receiving a user input requesting media control of the first external electronic device  210 . 
     In operation  525 , the electronic device  101  may broadcast advertising packets for identifying direction. The advertising packets for identifying direction may be packets including a PDU of ADV_EXT_IND. The advertising packets for identifying direction may include a constant tone extension (CTE). 
     In operation  530 , the second external electronic device  220  may calculate a signal position. The signal may correspond to advertising packets for direction identification broadcast from the electronic device  101 . According to an embodiment of the disclosure, the second external electronic device  220  may receive advertising packets for direction identification and perform IQ sampling based on the CTE. The second external electronic device  220  may obtain an angle of departure and/or an angle of arrival of the electronic device  101  based on the IQ sampling. According to an embodiment of the disclosure, the second external electronic device  220  may identify how far the electronic device  101  is located from each of a plurality of antennas based on the received strength of advertising packets for direction identification. The second external electronic device  220  may calculate the position of the electronic device  101  by using the obtained information on the angle of departure and/or the angle of arrival and the estimated distance based on the received strength. As a result of the calculation, when it is identified that the electronic device  101  is located within a predetermined area, the second external electronic device  220  may identify the electronic device  101  as a Bluetooth authenticated device and store the MAC address of the electronic device  101  as authentication information in the memory  420 . 
     In operation  535 , the electronic device  101  may broadcast an advertising packet for media control. The advertising packet for media control may include a new type of PDU. For example, the advertising packet for media control may include a PDU of NONCONN_CMD. The NONCONN_CMD may have a value of any one among the reserved bits of the PDU type field. For example, the NONCONN_CMD may have a “1001” value of the PDU type field. 
     In operation  540 , the electronic device  101  may transmit the first signal to the second external electronic device  220  in response to receiving advertising for media control. The first signal may include information requested to identify whether a device (e.g., electronic device  101 ) that broadcasts an advertising packet for media control corresponds to a Bluetooth authenticated device. For example, the first signal may include a MAC address of an advertising packet for media control. Since the first external electronic device  210  was already established a Bluetooth connection with the second external electronic device  220  for position identification of the electronic device  101 , the first signal may correspond to a data packet. 
     In operation  545 , the second external electronic device  220  may transmit the second signal to the first external electronic device  210  in response to receiving the first signal. The second signal may include information indicating whether the device (e.g., electronic device  101 ) that broadcasted an advertising packet for media control is a Bluetooth authenticated device. The second external electronic device  220  may identify whether a matching MAC address exists among the MAC addresses stored in the memory  420  based on the MAC address included in the first signal. For example, when a MAC address included in the first signal exists among the MAC addresses stored in the memory  420 , the second external electronic device  220  may identify a device (e.g., the electronic device  101 ) that broadcasted an advertising packet for media control is located within a predetermined area and is a Bluetooth authenticated device. The second external electronic device  220  may transmit the second signal including information indicating that the electronic device  101  is a Bluetooth authenticated device to the first external electronic device  210 . 
     In operation  550 , the first external electronic device  210  may broadcast an advertising packet for a media response. The advertising packet for media control may include a new type of PDU. For example, the advertising packet for media control may include a PDU of NONCONN_RSP. The NONCONN_RSP may have a value of any one of the reserved bits of the PDU type field. For example, the NONCONN_CMD may have a “1010” value of the PDU type field. The advertising packet for a media response may include information indicating whether a control command included in the advertising packet for media control broadcasted in operation  535  has been performed. For example, when the electronic device  101  has been identified as a Bluetooth authenticated device by including within the predetermined area, the first external electronic device  210  may perform the control command, and may include information indicating that the control command has been performed in the advertising packet for the media response.

       FIG.  7    illustrates a signal exchange diagram occurring in a wireless environment according to an embodiment of the disclosure. 
     Referring to  FIG.  7   , in operation  710 , the first external electronic device  210  may broadcast advertising packets. Operation  710  may correspond to operation  510  illustrated in  FIG.  5   . 
     In operation  715 , the electronic device  101  may perform a scan for searching for a Bluetooth connectable device. Operation  715  may correspond to operation  515  illustrated in  FIG.  5   .

     In operation  735 , the second external electronic device  220  may discard the authentication information. In order to enhance security, after identifying the electronic device  101  as a Bluetooth authenticated device, when a predetermined time elapses, the second external electronic device  220  may delete the authentication information. For example, even though the electronic device  101  is located within a predetermined area by receiving advertising packets for direction identification, authentication information on the electronic device  101  may be discarded when the predetermined time elapses. The predetermined time may vary according to user settings. The predetermined time may initiate from a time point at which the broadcasting is terminated when the electronic device  101  broadcasts advertising packets for direction identification.
