摘　　要：蓝牙是一种低成本、高可靠性的无线传输技术,蓝牙通信是实现PDA上GPS导航定位的首要环节。本文首先对GPS实时数据进行一定分析;然后详细介绍了Visual C# 2005环境下GPS与PDA蓝牙通信的实现流程,包括资源参数配置、打开串口、通信读写操作和关闭串口四个过程;继而基于PDA平台开发了相应的程序,实现了本文提出的GPS与PDA间蓝牙无线通信。实验结果表明,本文所述方法正确、可靠,适用于GPS与PDA间蓝牙通信。Bluetooth is a low-cost and high-reliability transmission technique. Bluetooth wireless communication is the first step of realizing the GPS navigation on PDAs. In this paper, the GPS data is analyzed first. Then, the realization flow of the Bluetooth wireless communications between GPSs and PDAs is introduced in detail. The flow contains four processes： configuring the serial port, opening the serial port, reading the communication resources and closing the serial port. Finally, a communication method of wireless Bluetooth is designed and realized. The proposed approach is operational, and it is suitable for the Bluetooth communications between GPSs and PDAs.
