Fig. 4 shows a flowchart of a method P100 for establishing a wireless communication connection according to an embodiment of the present description. The method P100 for establishing a wireless communication connection is applied to the system 001 for establishing a wireless communication connection. The system 001 for establishing a wireless communication connection may perform the method P100 for establishing a wireless communication connection provided in this specification. Specifically, the master device 200 and the target slave device 302 may read an instruction set stored in their local storage media and then execute the method P100 for establishing a wireless communication connection provided in this specification according to the specification of the instruction set. In the method P100 shown in fig. 4, the optical signal is transmitted by the master device 200, received and recognized by the target slave device 302. The method P100 may comprise:

s120: the master device 200 emits the optical signal to the preset range around the master device 200.

Specifically, step S120 may be performed by the processor 220 of the main device 200. As described above, the optical signal may carry data information, and the data information may be transmitted between the master device 200 and the target slave device 302 through the optical signal, so as to obtain identity information of both parties. In particular, the data information may be authentication data. The authentication data may be randomly generated data by the master device 200 for authenticating the target slave device 302. The target slave device 302 may recognize the authentication data and transmit to the master device 200, and the master device 200 may determine the target slave device 302 from the at least one slave device 300 according to the authentication data. The authentication data may be random numbers, random words, etc. The authentication data may also be a device identifier of the master device 200, and the target slave device 302 may obtain the device identifier of the master device 200 from the optical signal, thereby confirming the identity of the master device 200.

Step S120 may include:

s122: the master device 200 initiates the wireless communication connection and generates the authentication data.

Specifically, the master device 200 may initiate the wireless communication connection under a preset operation. The master device 200 may have a bluetooth connected switch. The preset operation may be to turn on a switch of the bluetooth connection. For example, when the master device 200 is a smart phone, the preset operation may be an operation in which the user enters a bluetooth setting of the master device 200 and opens a bluetooth connection. When the main device 200 is another electronic device, the preset operation may be that the user turns on a bluetooth switch or a bluetooth switch button of the main device 200, or the like.

S124: the master device 200 generates the optical signal corresponding to the authentication data based on a preset encoding rule and transmits the optical signal to the preset range.

Specifically, the master device 200 may store the encoding rule and/or the corresponding relationship between the optical signal and the authentication data in advance. Wherein the encoding rule may include encoding at least one of an illumination, a color, a frequency, and a flicker frequency of the light signal based on the authentication data. The master device 200 may obtain encoded data of the optical signal corresponding to the authentication data according to the encoding rule and/or the corresponding relationship between the optical signal and the authentication data, send the encoded data of the optical signal to the optical transmitting module 240, and generate the optical signal according to the encoded data of the optical signal by the optical transmitting module 240 to transmit the optical signal to the preset range.

S130: the target slave device 302 receives an optical signal emitted by the master device 200 to a preset range around, and determines authentication data in the optical signal.

The target slave device 302 is the device to which the master device 200 is to connect. The user may bring the target slave device 302 close to the master device 200 such that the target slave device 302 is within the preset range of the master device 200. The target slave device 302 is within the preset range of the master device 200 to receive the optical signal. The authentication data in the optical signal is identifiable by a target slave device 302 located within the preset range. The optical signal may be received by the optical receiving module 380 of the target slave device 302. Specifically, the target slave device 302 may initiate the wireless communication connection under a preset operation. The target slave device 302 may have a bluetooth connected switch. The preset operation may be to turn on a switch of the bluetooth connection. For example, when the target slave device 302 is a smart phone, the preset operation may be an operation in which the user enters a bluetooth setting of the target slave device 302 and opens a bluetooth connection. When the target slave device 302 is another electronic device, the preset operation may be that the user turns on a bluetooth switch or a bluetooth switch button of the target slave device 3020, or the like.

After the target slave device 302 starts the wireless communication connection, the light receiving module 380 of the target slave device 302 starts to receive the light signal. Specifically, step S130 may be: the target slave device 302 parses the optical signal based on a preset decoding rule, determining the authentication data. The target slave device 302 may store the decoding rule and/or the corresponding relationship between the optical signal and the authentication data in advance. The decoding rule corresponds to the encoding rule. The decoding rule may include parsing the light signal based on at least one of an illumination, a color, a frequency, and a flicker frequency of the light signal. The target slave device 302 may decode the received optical signal according to the decoding rule and/or the correspondence between the optical signal and the authentication data.

It should be noted that the optical signal is only generated within a preset range, and the optical signal can be received and identified only when the target slave device 302 is within the preset range. When the preset range is exceeded, the optical signal is invalid or attenuated, and correct authentication data cannot be identified. The light receiving module 380 of the target slave device 302 may face the light emitting module 240 of the master device 200 to ensure that the transmission of the optical signal is not obstructed.

S140: the target slave device 302 broadcasts the target broadcast data to the outside. Wherein the target broadcast data includes the authentication data.

The target broadcast data may be a directional broadcast or a non-directional broadcast. The target broadcast data can be received by the master device 200. The target broadcast data may include not only the authentication data but also a device identification of the target slave device 302. When the device identification of the master device 200 is included in the authentication data, the target broadcast data may be a directed broadcast transmitted to the master device 200. When the authentication data does not include the device identifier of the master device 200, but only includes random data for identity authentication, the target broadcast data may be an undirected broadcast carrying the random number.

The directed broadcast is a broadcast directed to a specific application or device, and the type of directed broadcast is for establishing a connection as quickly as possible. Such a message contains two addresses (the addresses are device identifications): the address of the broadcaster and the address of the originator. After receiving the directional broadcast message sent to the initiator, the initiator can immediately send a connection request as a response. The directional broadcast event must be repeated every 3.75 ms. This requirement allows the scanning device to scan only 3.75ms for messages to the targeted broadcasting device. Such a fast transmission would flood the broadcast channel with messages, which would result in other devices in the area not being able to broadcast to the originator.

The non-directed broadcast may include broadcast data and scan response data indicating that the current device may accept connection requests from any device.

S150: the master device 200 receives at least one broadcast data transmitted from at least one slave device 300.

The master device 200 may actively query and scan the surrounding slave devices 300. Each slave device 300 of at least one slave device 300 around the master device 200 may transmit broadcast data to the outside. The at least one slave device 300 corresponds to at least one broadcast data. Each of the at least one broadcast data may include therein a device identification of the corresponding slave device 300. The broadcast data may be non-directional broadcast data. Wherein the at least one slave device 300 may comprise a target slave device 302. The target broadcast data is included in the at least one broadcast data.

S160: the master device 200 determines target broadcast data from the at least one broadcast data.

When the device identifier of the master device 200 is included in the authentication data, the target broadcast data may be directional broadcast data for the master device 200, and at this time, the master device 200 can only receive the target broadcast data sent by the target slave device 302. And the main equipment determines the received broadcast data as the target broadcast data.

When the authentication data does not include the device identifier of the master device 200, but only includes random data for identity authentication, the target broadcast data may be an undirected broadcast carrying the random number. At this time, the master device 200 may receive at least one broadcast data transmitted from all of the at least one slave devices 300 around. The master device 200 may parse the at least one broadcast data, match the authentication data with the at least one broadcast data, and determine that the broadcast data including the authentication data is the target broadcast data.

S180: the master device 200 establishes the wireless communication connection with the target slave device 302 that transmitted the target broadcast data.

Step S180 may include:

s182: the master device 200 determines a device identification of the target slave device 302 based on the target broadcast data. As previously described, the device identification of the target slave device 302 is included in the target broadcast data.

S184: the master device 200 sends a connection request to the target slave device 302 based on the device identification of the target slave device 302, the target slave device 302 receives the connection request sent by the master device 200, and the master device 200 establishes the wireless communication connection with the target slave device 302.

After the master device 200 establishes the wireless communication connection with the target slave device 302, the master device 200 stores the device identifier of the target slave device 302, and the target slave device 302 stores the device identifier of the master device 200. The master device 200 and the target slave device 302 may then automatically connect.

The master device 200 may identify the authentication data. The target slave device 302 may determine the target slave device 302 from the at least one slave device 300 based on the authentication data. The authentication data may be random numbers, random words, etc. The authentication data may also be the device identification of the target slave device 302, and the master device 200 may obtain the device identification of the target slave device 302 from the optical signal, thereby confirming the identity of the target slave device 302.

Step S220 may include:

Specifically, the target slave device 302 may store the encoding rule and/or the corresponding relationship between the optical signal and the authentication data in advance. Wherein the encoding rule may include encoding at least one of an illumination, a color, a frequency, and a flicker frequency of the light signal based on the authentication data. The target slave device 302 may obtain encoded data of the optical signal corresponding to the authentication data according to the encoding rule and/or the corresponding relationship between the optical signal and the authentication data, send the encoded data of the optical signal to the optical transmitting module 340, and generate the optical signal according to the encoded data of the optical signal by the optical transmitting module 340 to transmit the optical signal within the preset range.

S230: the master device 200 receives an optical signal emitted by the target slave device 302 to within a preset range of the surroundings, and determines authentication data in the optical signal.

The master device 200 is located within the preset range of the target slave device 302 to receive the optical signal. The authentication data in the optical signal can be recognized by the master device 200 located within the preset range. The light receiving module 280 of the main device 200 may receive the light signal. Specifically, the master device 200 may initiate the wireless communication connection under a preset operation. The manner in which the master device 200 initiates the wireless communication connection may be the same as that described in step S122, and is not described herein again.

After the main device 200 starts the wireless communication connection, the light receiving module 280 of the main device 200 starts to receive the light signal. Specifically, step S230 may be: the master device 200 analyzes the optical signal based on a preset decoding rule, and determines the authentication data. The master device 200 may store the decoding rule and/or the corresponding relationship between the optical signal and the authentication data in advance. The decoding rule corresponds to the encoding rule. The decoding rule may include parsing the light signal based on at least one of an illumination, a color, a frequency, and a flicker frequency of the light signal. The master device 200 may decode the received optical signal according to the decoding rule and/or the corresponding relationship between the optical signal and the authentication data.

It should be noted that the optical signal is only generated within a preset range, and the optical signal can be received and identified only when the main device 200 is within the preset range. When the preset range is exceeded, the optical signal is invalid or attenuated, and correct authentication data cannot be identified. The light receiving module 280 of the master device 200 may face the light emitting module 340 of the target slave device 302 to ensure that the transmission of the light signal is not obstructed.

S240: the target slave device 302 broadcasts the target broadcast data to the outside. Wherein the target broadcast data includes the authentication data.

The target broadcast data may be a non-directional broadcast. The target broadcast data can be received by the master device 200. The target broadcast data may include not only the authentication data but also a device identification of the target slave device 302.

S250: the master device 200 receives at least one broadcast data transmitted from at least one slave device 300.
