In an implementation, the execution subject may include the first device. The first device and the second device may be different electronic devices.

It should be noted that the Bluetooth connection between the first device and the second device may be established by any Bluetooth connection method in the related art, which is not limited herein.

In an implementation, establishing the Bluetooth connection between the first device and the second device includes: broadcasting a fifth data packet to the second device, receiving second indication information sent by the second device, and establishing the Bluetooth connection between the first device and the second device. The fifth data packet carries an identification of the first device, and the second indication information is used for instructing the first device to establish the Bluetooth connection with the second device.

In an implementation, establishing the Bluetooth connection between the first device and the second device includes: receiving a sixth data packet broadcasted by multiple candidate devices, determining the second device from the multiple candidate devices, and establishing the Bluetooth connection between the first device and the second device. The sixth data packet carries identifications of the multiple candidate devices. For example, a candidate device list can be displayed on a page of the first device, and the second device can be determined from the multiple candidate devices based on a selection operation on the second device in the candidate device list from a user.

In some examples, the fifth data packet carries a capability (CAP) identification indicating whether the first device supports a fast wireless connection, the sixth data packet carries a CAP identification indicating whether the candidate device supports a fast wireless connection. For example, if both the first device and the second device support the fast wireless connection, step S102 and subsequent steps can be executed. On the contrast, if the first device and/or the second device does not support the fast wireless connection, an original wireless communication process can be executed.

In an implementation, establishing the Bluetooth connection between the first device and the second device includes: scanning Bluetooth devices within a surrounding area of the first device, paring the first device with a second device if the second device is scanned, and establishing the Bluetooth connection between the first device and the second device if the first device and the second device are successfully paired.

In an implementation, the second device is configured as a client of an AP created by the first device, i.e., the second device is configured as a station (STA). Alternatively, the second device is configured as a group client of a group created by the first device. The second data packet carries a MAC address of the second device, a supplicant nonce, and a CAP identification of the second device, and so on.

For example, the third secret key may include a group temporal key (GTK). The third secret key may be generated by any key generation method in the related art, which is not limited herein.

In an implementation, generating the third secret key may include: splicing the MAC address of the first device and a group nonce (GNonce) to obtain a first spliced result, and generating the GTK based on the first spliced result and a group master key (GMK). It should be noted that GNonce is a random number generated by the first device. ANonce and GNonce are different random numbers.

In some examples, key derivation may be performed for the GMK based on the first spliced result to obtain the GTK. It should be noted that the key derivation may be performed for the GMK by using any key derivation method in the related art. The key derivation method may include a pseudo-random function (PRF).

The execution order of the step of sending the first data packet to the second device and the step of receiving the second data packet sent by the second device are not limited herein.

Or the first data packet may be sent to the second device after the second data packet sent by the second device can be received.

At step S103, a wireless connection between the first device and the second device is established. The establishing of the wireless connection does not include an interaction process of handshake messages.

It should be noted that the handshake messages may include handshake messages defined by any wireless communication protocol in the related art, such as the four-way handshake messages.

In an implementation, establishing the wireless connection between the first device and the second device includes: creating a wireless access point, or creating a group and setting the first device as an owner of the group; receiving an authentication request message (Auth Request for short) sent by the second device; sending an authentication response message (Auth Response for short) to the second device; receiving an association request message (Assoc Request for short) sent by the second device; and sending an association response message (Assoc Response for short) to the second device.

In this way, transmission of the first data packet and the second data packet can be performed through the Bluetooth connection between two devices. That is, two data packets can be shared between the two devices through the Bluetooth connection, so that the interaction process of handshake messages can be omitted during the establishing of the wireless connection, thereby facilitating reducing the number of message interactions and shortening consumption time of the message interactions, and thus shortening the time of the establishing of the wireless connection and improving the efficiency of the establishing of the wireless connection.

FIG. 14 illustrates a block diagram of an electronic device according to an embodiment.

As shown in FIG. 14, the electronic device 300 includes: a memory 310, a processor 320, and a bus 330 connected different components (including the memory 310 and the processor 320). The memory has computer programs stored thereon, when the processor 320 executes the computer programs, the wireless communication method of the embodiments of the disclosure is implemented.

The bus 330 represents one or more of several types of bus structures, including a memory bus or a memory controller, a peripheral bus, a local bus of a graphics acceleration port, a processor, or any bus structure of multiple bus structures. For example, these architectures include but are not limited to an industrial standard architecture (ISA) bus, a microchannel architecture (MAC) bus, an enhanced ISA bus, a video electronics standards association (VESA) local bus, and a peripheral component interconnect (PCI) bus.

The electronic device 300 typically includes various electronic device readable media. These media can be any available media that can be accessed by the electronic device 300, including volatile and non-volatile media, removable and non-removable media.

The memory 310 may also include a computer system readable medium in the form of volatile memory, such as random access memory (RAM) 340 and/or a cache memory 350. The electronic device 300 may further include other removable/non-removable, volatile/non-volatile computer system storage media. For example, the storage system 360 can be used to read and write non-removable, non-volatile magnetic media (not shown in FIG. 14, commonly referred to as “hard disk drive”). Although not shown in FIG. 14, a disk driver for reading and writing a removable non-volatile disk (such as “floppy disks”) and an optical disk driver for reading and writing a removable non-volatile optical disk (such as CD ROM, DVD ROM, or other optical media) can be provided. In these cases, each driver can be connected to the bus 330 through one or more data media interfaces. The memory 310 may include at least one program product having a set of (e.g., at least one) program modules configured to perform the functions of the embodiments disclosed herein.

A program/utility 380 having a set of (at least one) program modules 370 may be stored in, for example, the memory 310. Such program modules 370 include, but are not limited to, an operating system, one or more application programs, other program modules, and program data, each or some combination of which may include an implementation of a network environment. The program module 370 typically performs the functions and/or methods described in the embodiments disclosed herein.

The electronic device 300 can also communicate with one or more external devices 390 (such as keyboard, pointing device, display 391, etc.), as well as with one or more devices that enable users to interact with the electronic device 300, and/or with any device that enables the electronic device 300 to communicate with one or more other computing devices (such as network card, modem, etc.). This communication can be performed through an input/output (I/O) interface 392. Moreover, the electronic device 300 can also communicate with one or more networks (such as local area network (LAN), wide area network (WAN), and/or public network, such as the Internet) through a network adapter 393. As shown in FIG. 14, the network adapter 393 communicates with other modules of the electronic device 300 through the bus 330. It should be understood that although not shown in the figure, other hardware and/or software modules can be used in conjunction with the electronic device 300, including but not limited to microcode, device drivers, redundant processing units, external disk driver arrays, RAID systems, tape drivers, and data backup storage systems.

The processor 320 performs various functions and data processing by executing the programs stored in the memory 310.
