Hi Simon,

Thanks, that clears a lot!

So to resume, a netconn_close() should always be follows by a
netconn_delete(). A close without delete makes no sense at all?

Then this should work (theoretical)

    while (1)
        conn = netconn_new_with_callback(NETCONN_TCP,
        err0 = netconn_bind(conn, NULL, 0);
        err1 = netconn_connect(conn, &remote_ip, 7);
        err2 = netconn_close(conn);

And after the close and delete all buffers are freed and no pending TCP
packets are there to resend or ports locked? Returning from close (or
delete) means completely finished? Not needed to wait.
