Hello,
I'm trying to send a string from an arduino gsm board to an labview server. From arduino board i think everythink is ok, i specified ip adress and port number, the problem is that it can't connect to the labview server and i don't have any more ideas where can be the proble.
I tryed with hercules to listen o port and it works fine, i received the data from arduino.
I leave here the code i used and the VI for server.
