本文介绍了通过Winsock接口使用蓝牙的编程方法，适用于所有基于套接字的编程。给出了服务器和客户端的操作流程及代码示例，服务器创建套接字、绑定通道、监听连接；客户端创建套接字、连接服务器并收发请求。

Using Bluetooth through Winsock interfaces is common to all socket-based programming.
The server creates the socket, binds it to a given RFCOMM channel, exports the SDP record advertising this channel, and then listens for incoming connections. The following code example shows how this is done.

SOCKET s = socket(…);
bind(s, …);
listen(s, …);
for(; ;){
SOCKET s2= accept(s, …);
SpinThreadsForConnection(s2);
}

The client then creates the socket, connects it to the server using a known server channel obtained from the SDP query or a UUID of the target service, and then starts sending and receiving requests. The following code snippet demonstrates how this is done.

SOCKET s = socket(…);
connect(s, …);
send(s, …);        // send request
recv(s, …);        // get response
closesocket(s);    // done
