# HFP | ||
|
||
本文基于HFP1.9 pdf,以及一些cfa和ellisys讲解 | ||
|
||
## 简介 | ||
|
||
HFP(Hands-free Profile),可以让蓝牙设备可以控制电话,如接听、挂断、拒接、语音拨号等,拒接、语音拨号要视蓝牙耳机及电话是否支持。 | ||
|
||
HFP定义了音频[网关](http://baike.baidu.com/view/807.htm)(Audio Gateway)和免提组件(Hands Free)两个角色: | ||
|
||
**AG**–该设备为音频(特别是手机)的输入/输出网关。通常指的是手机 | ||
|
||
**HF**–该设备作为音频[网关](http://baike.baidu.com/view/807.htm)的远程音频输入/输出机制,并可提供若干遥控功能。通常指的是耳机或者其他免提设备。 | ||
