Therefore, turn off the Wi-Fi direct connection between the current historical Wi-Fi device and the Wi-Fi direct connection initiating device whose interaction heat is less than the first threshold. Connect the link to save the power of the wifi direct connection initiating device and the current historical wifi device. When the interaction between the wifi direct connection initiating device and each current historical wifi device is less than the second threshold and greater than or equal to the first threshold, it indicates that the interaction frequency between the wifi direct connection initiating device and each current historical wifi device is moderate, and the wifi direct connection initiating device and each current historical wifi device have a moderate interaction frequency. The usage rate of the Wi-Fi direct link between the current historical Wi-Fi devices is low, and the continuous activation will consume a lot of power between the Wi-Fi direct connection initiating device and each current historical Wi-Fi device, so the sleep interaction heat is less than the second threshold and greater than or equal to the first The Wi-Fi direct connection link between the Wi-Fi direct connection initiating device and each current historical Wi-Fi device at the threshold value will wake up the dormant Wi-Fi Direct connection link when there is an interaction requirement, which further saves the power of the Wi-Fi Direct connection initiating device and each current historical Wi-Fi device. .

Step S103: Send an instruction to the peer wifi device supporting wifi direct connection through the direct link with the peer wifi device supporting wifi direct connection, so that the peer wifi device supporting wifi direct connection executes the instruction.
