CONTROLLING METHOD FOR COEXISTENCE OF DUAL MODES, WI-FI CHIP, AND COMMUNICATION DEVICE

A controlling method for coexistence of dual modes, including: when a Wi-Fi chip in a station (STA) mode needs to switch from a first signal channel to a second signal channel, sending, by the Wi-Fi chip in an access point (AP) mode, a control message to an external device, where the control message indicates that the Wi-Fi chip is in an absent status within a preset period of time, thus enabling the external device to stop transmitting data to the Wi-Fi chip based on the control message within the preset period of time; within the preset period of time, switching the Wi-Fi chip to work in the second signal channel; and when the preset period of time ends, switching the Wi-Fi chip back to work in the first signal channel.
