摘　　要：蓝牙技术是近年来迅速发展的一项短距离无线通信技术.OBEX作为蓝牙协议栈中面向应用的会话层协议,提供了灵活的目标文件交换方式.本文研究了OBEX协议的原理及结构,仔细分析了OBEX层模块间的接口和数据流.并着重讨论了基于OBEX的文件传输应用的实现技术,最后介绍了作者开发的蓝牙设备间通过无线信道传输文件的一个实例.Recently, Bluetooth has become a very promising technique for short-ranged wireless telecommunication and the applications based on Bluetooth have become more and more popularized. OBEX (Object Exchange), a user-oriented protocol in Bluetooth stack, provides a united criterion for putting and getting data objects (File and Directory) simply and flexibly. In this paper, we analyze the inner mechanism and module classification of OBEX, and figure out the data flow process among different layers, especially the relationship between File Transfer and OBEX . In particular, we focus on the realization technique of 'File Transfer over OBEX' , such as the data flow of event and user driven, and introduce an instance of our approach to file transfer application through wireless media.
