如何通过蓝牙发送一个文本文件？能解决，给多少分都行！
最好能调用系统的蓝牙模块。

------解决方案--------------------
是沙发吗？好像是！
你描述的不是很清楚，我大概说下。
使用蓝牙通讯可以直接调用winsock访问蓝牙的协议站，就是简单的WSAXXX,send,recv；
另外一种方式是通过蓝牙专用的虚拟串口驱动，用DeviceIoControl访问com驱动,
createfile,writefile,readfile

------解决方案--------------------
最简单的办法是当串口来处理
------解决方案--------------------
蓝牙连上然后用socket啊很简单的么系统的蓝牙模块好像也有相关的东东
你看看 btdrt这个模块什么的吧
------解决方案--------------------
socket需要一个客户端还需要一个服务器，增加工作量。可以用OBEX

C/C++ code
