I made a simple RFCOMM client, but fail to receive from (note that send works well). Here is the code : socket = bluetooth.BluetoothSocket(bluetooth.RFCOMM) socket.connect(("D8:A0:1D:56:3E:52", 1)) while True: data = socket.recv(6) for d in data: print(hex(ord(d))) Other...

如果TCP连接2小时(7200秒)内没有数据传输,则发送嗅探包,每隔75秒发送一次,共重试9次。9次对方都没响应,则表明此连接已死。(留个问题,这个时候socket会给fd发送什么信号??) 以linux为例: recv的man对返回值的介绍如下: RETURN VALUE These calls return the number of bytes received, or -1 if an error oc...
