2. Priority to use Wi-Fi or Bluetooth according to demand.
If you need to use Wi-Fi urgently, it is recommended that you turn off bluetooth first. If you need to use bluetooth urgently, it is recommended to turn off Wi-Fi first to avoid interference, and give priority to completing the current tasks.
