Hello Angus, Still not working but I found something, if I do a .SendTo inside the OnDataAvailable after the .ReceiveFrom, it works, no bind error, but in my program I have to pass the received data to some worker queue that take some seconds to produce the answer and then when it tries to .SendTo it produce the error. I tried to save the SrcSocket(sockaddr_in) from the .ReceiveFrom to reuse it with .SendTo but without success, still bond error. May be I need to do something more if I .SendTo outside OnDataAvailable ?
