# 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。
