Really? Both netconn_recv() and netconn_send() call api_msg_post() which pends on conn->mbox, and that conn (& mbox) is the same for both threads. So when tcpip_thread posts to that mbox, it's unknown which call (recv or send) has finished. > sure for "select"). You can also use another socket to send, > but don't bind it to 1900/udp...
