When creating a socket with the wip_create() (wiplib) or AT+WIPCREATE (wipsoft) just after the call of wipclose() (wiplib) or AT+WIPCLOSE (from wipsoft) of that socket (same address and port) , that created socket cannot function properly as expected because the socket closing needs time and is not immediate.
Workaround: The socket open call should not be called just after a socket close call: After a call to wip_close() or AT+WIPCLOSE to close a socket, a delay of one second is necessary before calling again the wip_create() or AT+WIPCREATE to open a new socket. If due to that asynchronous process the socket open call is too close to the socket close call and that issue is encountered, another workaround is to close and reopen that socket.
