摘要：通过对蓝牙高级音频分发框架(A2DP)协议栈进行系统地分析，提出了一种基于消息机制的协议方案，在无A2DP框架的蓝牙1.1协议栈基础上实现了轻型的A2DP应用框架，并且利用嵌入式蓝牙开发平台，实现了基本的点对点蓝牙立体声音频数据的传输。-Abstract: The distribution of the fr a mework of the Bluetooth Advanced Audio (A2DP) protocol stack to carry out systematic analysis, a mechanism based on the news program of the agreement, the fr a mework in the absence of A2DP Bluetooth 1.1 protocol stack based on a lightweight application fr a mework A2DP, and the use of Bluetooth embedded development platform, to achieve a basic point-to-point Bluetooth stereo audio data transmission.
