[0037] Please refer to Figure 4 , in an embodiment of the present invention, the classic Bluetooth device is a mobile phone, and the device supporting Bluetooth Low Energy (BLE) audio is a headset. The multi-functional gateway is a multi-mode wireless system that supports both classic Bluetooth and Bluetooth Low Energy (BLE) audio. An A2DP connection is established between the mobile phone and the multi-functional gateway. The mobile phone serves as the sound source and sends audio information to the multi-functional gateway.
