摘要 文中首先介绍了蓝牙协议栈中的主机控制器接口(HCI),服务发现协议(SDP)及逻辑链路控制与适配协议(L2CAP),并通过一个具体的嵌入式蓝牙数据传输系统,实现了这些协议。文章给出了该系统的硬件框图、软件的总体设计模块(主机控制器接口模块﹑服务发现模块和数据传输模块)、以及软件设计流程,最终实现了两个蓝牙模块之间的无线数据传输。 HCI, SDP and L2CAP in Bluetooth protocol stack are described first, which are implemented by a specific embedded Bluetooth system for data transmission. This paper also gives the hardware frame chart, software module (the module of HCI, the module of service discovered, module of data transmission) and software flow chart of the system. Finally, the wireless data transmission between the two Bluetooth modules is achieved.
