Error in Get/Put

Projects Networking, Protocols, and Devices

It probably does not like the CR/LF in the request, and no double quote. I would try this:

  mySerial.print("AT+HTTPPARA=\"URL\",\"http://winacro.com/script.php?value=");
  mySerial.print(value);
  mySerial.println("\"");

I have not tested it. I'm not sure if it needs a blank line like an ethernet request.
