BluetoothHeadsetClient
次要真现HFP和谈&#Vff0c;次要真现拨打、接听、挂断电话&#Vff08;AG侧、HF侧&#Vff09;、切换声道罪能。

AG&#Vff08;Audio Gate&#Vff09;音频网关—音频方法输入输出网关 。
HF&#Vff08;Hands Free&#Vff09;免提—该方法做为音频网关的远程音频输入/输出机制&#Vff0c;并可供给若干遥控罪能。
正在车载蓝牙中&#Vff0c;手机侧是AG&#Vff0c;车载蓝牙侧是HF&#Vff0c;正在android源代码中&#Vff0c;将AG侧称为HFP/AG&#Vff0c;将HF侧称为HFPClient/HF。
