[0074] In order to enable those of ordinary skill in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0075] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0076] In the technical solutions of the present disclosure, the acquisition, storage, use, processing, etc. of data all comply with the provisions of relevant laws and regulations.

[0077] Figure 1 It is a flowchart of a wireless communication method shown according to an exemplary embodiment. As Figure 1 shown, the wireless communication method of the embodiments of the present disclosure includes the following steps.

[0078] S101, establish a Bluetooth connection between the first device and the second device.

[0079] It should be noted that the execution subject of the wireless communication method in the embodiments of the present disclosure is an electronic device. For example, it may include a mobile phone, a notebook, a desktop computer, a vehicle-mounted terminal, a smart home appliance, a wearable device, etc. Among them, the wearable device may include a wrist-worn device (such as a smart watch, a smart bracelet), a head-worn device, a foot-worn device, etc. The wireless communication method in the embodiments of the present disclosure may be executed by the wireless communication device in the embodiments of the present disclosure. The wireless communication device in the embodiments of the present disclosure may be configured in any electronic device to execute the wireless communication method in the embodiments of the present disclosure.

[0080] In one implementation manner, the execution subject may include a first device, and the first device and the second device are different electronic devices.

[0081] It should be noted that establishing a Bluetooth connection between the first device and the second device may be implemented by using any Bluetooth connection method in the related art, and no further limitation is made here.

[0082] In one implementation manner, establishing a Bluetooth connection between the first device and the second device includes broadcasting a fifth data packet to the second device, where the fifth data packet carries the identifier of the first device, and receiving the second indication information sent by the second device, where the second indication information is used to instruct the first device to establish a Bluetooth connection between itself and the second device, and establishing a Bluetooth connection between the first device and the second device.

[0083] In one implementation manner, establishing a Bluetooth connection between the first device and the second device includes receiving sixth data packets broadcast by multiple candidate devices, where the sixth data packet carries the identifier of the candidate device, determining the second device from the multiple candidate devices, and establishing a Bluetooth connection between the first device and the second device. For example, a list of candidate devices may be displayed on the page of the first device, and the second device is determined from the multiple candidate devices based on the user's selection operation on the second device in the list of candidate devices.

[0084] In some examples, the fifth data packet carries the CAP (Capability) capability identifier indicating whether the first device supports fast wireless connection, and the sixth data packet carries the CAP capability identifier indicating whether the candidate device supports fast wireless connection. For example, if both the first device and the second device support fast wireless connection, step S102 and its subsequent steps may be continued; otherwise, if the first device and / or the second device does not support fast wireless connection, the original wireless communication process may be executed.

[0085] In one embodiment, establishing a Bluetooth connection between a first device and a second device includes scanning for Bluetooth devices in the surrounding area of the first device. If the second device is scanned, the first device and the second device are paired. If the pairing between the first device and the second device is successful, a Bluetooth connection between the first device and the second device is established.

[0086] S102, based on the Bluetooth channel between the first device and the second device, send a first data packet to the second device and receive a second data packet sent by the second device, where both the first data packet and the second data packet are used for wireless communication between the first device and the second device.

[0087] It should be noted that there are no excessive limitations on the first data packet and the second data packet.

[0088] In one embodiment, the first device serves as the creator of a wireless AP (Access Point) or the owner of a group (Group Owner). The first data packet carries the connection password of the wireless network, the channel where the first device is located, the SSID (Service Set Identifier) of the wireless network, the MAC (Media Access Control) address of the first device, the IP (Internet Protocol) address assigned to the second device, ANonce (Access Point Nonce), the third key, the capability identifier of the first device, etc.

[0089] In one embodiment, the second device serves as a client of the wireless access point created by the first device, that is, the second device serves as a STA (Station), or the second device serves as a client of the group created by the first device (Group Client). The second data packet carries the MAC address of the second device, SNonce (Supplicant Nonce), and the capability identifier of the second device, etc.

[0090] It should be noted that if the first device is the owner of the group, the connection password of the wireless network includes the password for joining the group created by the first device. ANonce is a random number generated by the first device, and SNonce is a random number generated by the second device. There are no excessive limitations on the third key. For example, the third key is used for multicast communication and / or broadcast communication between the first device and multiple second devices. For example, the third key may include GTK (Group Temporal Key). To generate the third key, any key generation method in related technologies can be used to implement it, and there are no excessive limitations here.

[0091] In one embodiment, generating a third key may include concatenating the MAC address of the first device and the GNonce (Group Nonce) to obtain a first concatenation result, and generating a GTK based on the first concatenation result and the GMK (Group Master Key). It should be noted that the GNonce is a random number generated by the first device, and the ANonce and GNonce are different random numbers.

[0092] In some examples, the GTK may be obtained by performing key derivation on the GMK based on the first concatenation result. It should be noted that the key derivation of the GMK can be implemented by any key derivation method in related technologies, and the key derivation method may include a PRF (Pseudo-Random Function).

[0093] It should be noted that the execution order of sending the first data packet to the second device and receiving the second data packet sent by the second device is not overly limited. For example, after sending the first data packet to the second device, the second data packet sent by the second device is received, or after receiving the second data packet sent by the second device, the first data packet is sent to the second device.

[0094] S103, establish a wireless connection between the first device and the second device, where the process of establishing the wireless connection does not include the interaction process of handshake messages.

[0095] It should be noted that the handshake message may include handshake messages defined by any wireless communication protocol in related technologies. For example, it may include a Four-Way Handshake message.

[0096] In one embodiment, establishing a wireless connection between a first device and a second device includes creating a wireless access point or creating a group with the first device as the owner of the group, receiving an Authentication Request (Auth Request) message sent by the second device, sending an Authentication Response (Auth Response) message to the second device, receiving an Association Request (Assoc Request) message sent by the second device, and sending an Association Response (Assoc Response) message to the second device. It can be understood that the process of establishing a wireless connection includes the interaction process of two Auth messages (i.e., Auth Request and Auth Response) and the interaction process of two Assoc messages (i.e., Assoc Request and Assoc Response).

[0097] In one embodiment, establishing a wireless connection between a first device and a second device includes installing a first key and a third key. It should be noted that the first key and the third key are different keys, and no excessive limitation is imposed on the first key. For example, the first key is used for unicast communication between the first device and the second device. For example, the first key may include a PTK (Pairwise Temporal Key). For the relevant content of generating the first key, reference can be made to the following embodiments and will not be elaborated here.

[0098] In some examples, establishing a wireless connection between a first device and a second device includes installing a PTK and a GTK.

[0099] S104, perform wireless communication between the first device and the second device based on the first data packet and the second data packet.

[0100] In one embodiment, performing wireless communication between a first device and a second device based on the first data packet and the second data packet includes extracting first target data required for wireless communication from the first data packet and the second data packet, and / or generating first target data based on the first data packet and the second data packet, and performing wireless communication between the first device and the second device based on the first target data. It should be noted that no excessive limitation is imposed on the first target data. For example, it may include the first key, the third key, the IP address of the first device, the MAC address of the first device, the IP address of the second device, the MAC address of the second device, etc.

[0101] It should be noted that, based on the first data packet and the second data packet, the generation of the first target data can be implemented by any wireless communication method in the related art, and no excessive limitation is imposed here.

[0102] In one implementation, before performing wireless communication between the first device and the second device, it further includes receiving an ARP (Address Resolution Protocol) request message (abbreviated as ARP Request) sent by the second device, and sending an ARP response message (abbreviated as ARP Response) to the second device. Among them, the ARP request message carries the MAC address of the second device, and the ARP response message carries the MAC address of the first device. Thus, through the interaction process of two ARP messages (i.e., ARP Request and ARP Response), the MAC addresses of the first device and the second device can be shared between the two devices.
