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。

[解决办法]
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

[解决办法]
最简单的办法是当串口来处理
[解决办法]
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
[解决办法]
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
