摘　　要：蓝牙是一种基于ISM频段的无线短距离通信技术,已经广泛应用在多种民用产品中。蓝牙耳机和音频网关作为蓝牙技术的典型应用,使人机语音接口可以从通信终端分离,从而增加了通话中用户的活动半径和灵活性。本文给出了以CSR公司BlueCore2-External芯片为核心的蓝牙耳机和音频网关开发方案,指出了在软硬件开发中应注意的一些问题。着重介绍了在蓝牙开发中应严格遵循的蓝牙规范和其中专门用于指导蓝牙耳机、音频网关开发的headset剖面。最后给出例子,简要说明高层应用程序建链的运行流程和具体实现。Bluetooth is a kind of short distance wireless communication technology which has already been applied in many civilian application fields. Bluetooth headset and audio gateway as typical Bluetooth applications free the manmachine interface from communication terminal, which result in the increase of move radius and flexibility during calling. In this paper, the development solution to headset and audio gateway based on BlueCore2-Externa from CSR is offered. At the same time, pointing out some problems which should be paid attention to during hardware and software development. The Bluetooth specification which should be obeyed strictly during Bluetooth development and headset profile which especially guides the headset and audio gateway development are emphatically introduced. In the end, we have an instance to briefly explain how the application in the high layer implements the connection.
