Please refer to FIG. 2, which is a diagram of an embodiment of the present invention. A pairing connection diagram of two electronic devices with wireless direct connection. The electronic devices 5A and 5B in FIG. 2 are electronic devices having a wireless direct connection function, and the electronic devices 5A and 5B have a control unit and a wireless communication module as in the electronic device 5 in FIG. 1 . Device 5 will not be described here. As shown in FIG. 2, at time 0-t1, the electronic device 5A executes the search procedure and issues a heuristic request P1 to the electronic device 5B on the first channel of the social channel, and determines whether a heuristic response corresponding to the heuristic request is received. For example, the heuristic request P1 issued by the electronic device 5A includes the identification information of the electronic device 5A and the identification information of the electronic device 5B, but is not limited thereto. At time 0-t1, the electronic device 5B executes the listening program on the channel 6 and the channel 11, respectively. Since the electronic device 5B does not execute the listening program on the first channel, the electronic device 5A is not received. The heuristics issued by Channel 1 require P1.

At time t1-t3, the electronic device 5A is respectively on channel 6 and Channel 11 issues a probe request P1, and the electronic device 5B executes the listening program on the eleventh channel, and the first channel executes the search program. Since the electronic device 5A issues the probe request P1 on the eleventh channel, and the electronic device 5B does not execute the listening program on the eleventh channel, the electronic device 5B does not receive the probe request P1 of the electronic device 5A. Therefore, the electronic device 5A and the electronic device 5B cannot complete the pairing.

At time t3-t4, the electronic device 5B performs a search procedure on the first channel. The sequence also issues a heuristic request P1 and determines whether a heuristic response P2 corresponding to the heuristic request P1 is received. Since the electronic device 5A is currently performing the listening procedure and is also located on the first channel, the electronic device 5A will receive the heuristic request P1 from the electronic device 5B and respond to the heuristic request P1 to issue the heuristic response P2.

When the electronic device 5B issues the probe request P1 and receives the corresponding probe response P2, the electronic device 5A and the electronic device 5B complete the pairing connection, but not limited thereto.

It should be noted that the electronic device 5A or the electronic device in this embodiment When the device 5B performs a search or a listening program, the execution time of the first channel is greater than the execution time of the sixth channel and the eleventh channel. Electronic device 5A and electronic device The execution time of the first channel is increased, and the probability that the electronic device 5A and the electronic device 5B are successfully paired on the first channel is also increased. Therefore, the pairing time of the electronic device 5A and the electronic device 5B can be reduced. In an embodiment, when the execution time of the first channel increases, the execution time of the sixth channel or the eleventh channel is also reduced, but not limited thereto. For example, if the control unit 11 increases the execution time of the first channel by the electronic device 5A by 10 milliseconds, the total execution time of the sixth channel and the 11th channel will be reduced by 10 milliseconds, but not limited thereto. In the embodiment of FIG. 2, the first channel is a specific channel, and the sixth channel and the eleventh channel are non-specific channels, but are not limited thereto. In another embodiment, the channel 6 or the channel 11 may be a specific channel, and the channel in the social channel that does not include the specific channel is a non-specific channel.

As shown in Fig. 3, the flow starts in step S31, setting one of the channels of the social channel to a specific channel, and proceeds to step S32. For example, the electronic device 5A sets one of the first channel, the sixth channel, or the eleventh channel as a specific channel. In an embodiment, the specific channel may be set by the user or the electronic device 5A has been set at the factory, but is not limited thereto. In an embodiment, in order to accelerate the pairing connection time of the electronic device 5A and the electronic device 5B, the specific channels of the electronic device 5A and the electronic device 5B are generally set to the same channel.

In step S32, the electronic device 5A sets the preset by the control unit 11. Set the schedule and proceed to step S33. The preset timetable is used to determine the execution time of each social channel when the electronic device 5A performs the search/listening process. For example, the control unit 11 sets the execution time of the first channel, the sixth channel, and the eleventh channel, respectively, when the search/listening program is executed. It should be noted that, in the preset schedule set by the control unit 11, the execution time of the specific channel may be greater than the execution time of each non-specific channel. In an embodiment, when the search unit 11 executes the search program and the listening program, the execution time corresponding to the same social channel may be the same or different.

In step S33, the electronic device 5A determines the search according to the preset schedule. The execution time of each social channel at the time of finding/listening the program, and proceeds to step S34.

In an embodiment, the execution order of the first channel, the sixth channel, and the eleventh channel may be performed according to the specification of the wireless direct connection, or may be performed according to a preset sequence, but is not limited thereto. For example, the control unit 11 sets the specific channel to have the highest priority, so the specific channel is preferentially executed when the search/listening program is executed, but is not limited thereto.

In step S34, the electronic device 5A determines whether a corresponding message is received. number. When the electronic device determines that the corresponding signal is received, the process proceeds to step S35; otherwise, the process returns to step S33. For example, when the electronic device 5A executes the search process, the control device 11 determines whether a corresponding heuristic response is received. In another embodiment, when the electronic device 5A is executing the listening program, the control device 11 determines whether a corresponding heuristic request is received.

In step S35, the electronic device 5A determines to complete with another electronic device. Paired connection. For example, when the electronic device 5A performs a search procedure on the first channel to issue a heuristic request to the electronic device 5B, and receives a probe response sent by the electronic device 5B, the control unit 5 determines that the electronic device 5A and the electronic device 5B complete the pairing.
