I have implemented this code to read GPS coordinates and send them to a server. The coordinates appear on the serial monitor, but the server does not receive anything. Could this be more of a server problem? Or a mistake in this code?
Do you have any recommendations as to where my problem is? I would appreciate all and any help suggestions. Thank you very much!
