/*************************************************************
此文件函数主要是蓝牙发射器接口处理
1、关于AG对讲功能使用说明：
发射器需要通过user_emitter_cmd_prepare接口来给接收器发送命令,例如：
(1)发射器主动发起通话
user_emitter_cmd_prepare(USER_CTRL_HFP_CALL_LAST_NO, 0, NULL)
(2)发射器主动关断通话
user_emitter_cmd_prepare(USER_CTRL_HFP_CALL_HANGUP, 0, NULL)
(3)接收器来电接听
user_emitter_cmd_prepare(USER_CTRL_HFP_CALL_ANSWER, 0, NULL)
