A missing "\r\n" after the "HTTP/1.1"?

Yes and another missing \r\n at the end (assuming the println function actually sends \r\n and not just \r or \n).
The GET request needs to end with 2 \r\n, otherwise the server won't do anything, as in your case.

- Thu Feb 26, 2015 1:35 am #10761 Now I get a bad request page.

How do I know what the AT+CIPSEND length should be?

Code: Select all+IPD,1452:HTTP/1.1 400 Bad Request

- Sat Feb 28, 2015 4:06 pm #11003 Finally got this working. I just kept changing the CIPSEND length 1 at a time until it worked. This makes no sense to me but it works.

Code: Select all  mySerial.println("AT+CIPSEND=46");

      flag = 2;
    }

    if (ledState == HIGH && flag == 2)
    {
      Serial.println("Sending GET request...");
      ledState = LOW;
      mySerial.println("GET http://www.daqduino.com/update/index.htm");

- Sat Feb 28, 2015 4:30 pm #11005 That count makes sense. Your string is 44 chars. CR and LF (because of println) make it 46.
