蓝牙仿真串口的研究与实现

Research and Implementation of Emulated Serial Ports in Bluetooth

蓝牙协议栈定义了一个称为RFCOMM的串行端口抽象。文中在给出一种具体的RF COMM多路复用实现的基础上 ,对比分析了独享与共享两种仿真串口的实现方法及实用特性 ,指出共享实现方式具有节约服务器信道并提高客户连接成功率的优点。最后给出了在Windows 2 0 0 0平台下SPP的具体实现框架 ,可对设计基于RFCOMM的应用提供指导。

The Bluetooth Stack defines a serial port abstract named RFCOMM. On the basis of an implementation of RFCOMM multiplex,this paper analyzes the implementation and utility property of the two kind (exclusive and shared) of emulated serial ports,pointing out that the shared mode not only saves the server channels for the server,but also enhances the success probability of the client's connection attempt. A detailed implementation frame of SPP on the Windows 2000 platform is also presented. This paper can serve as a guideline to the design of applications based on RFCOMM.
