Arduino & ESP8266 HTTP GET Response handling

Question

I'm successfully connecting my server but I can't handle the response data. esp8266.find("+PID,") doesn't work. My loop code is below:

void loop() {
  String cmd = "AT+CIPSTART=\"TCP\",\""; //make this command: AT+CPISTART="TCP","192.168.88.35",80
  cmd += DST_IP;
  cmd += "\",80\r\n";
  esp8266.print(cmd);
  //wait a little while for 'Linked'
  delay(3000);

  //This is our HTTP GET Request change to the page and server you want to load.
  cmd = "GET /~atolye/wifiModule.php?id=123 HTTP/1.0\r\n";
  cmd += "Host: 159.122.115.70\r\n\r\n";
  esp8266.print("AT+CIPSEND=63\r\n");
  if(esp8266.find(">")) {
    //Send our http GET request
    Serial.println("SENDING THE REQUEST");
    esp8266.print(cmd);
    if(esp8266.find("+IPD,")) {
      Serial.println("\r\nIPD FOUND");
      if(esp8266.find("\"1")) {
        int value = esp8266.read()-48;
        Serial.println("\r\nVALUE FOUND");
        Serial.println(value);
        esp8266.println(value);
      }
    } else {
      Serial.println("\r\n!! IPD NOT FOUND");
    }
  }
  else {
    Serial.println("\r\nERROR > DOESN'T EXIST");
  //Something didn't work...
    esp8266.print("AT+CIPCLOSE\r\n");
  }

}

And this is the output: As you can notice, IPD NOT FOUND executes before RESPONSE arrives. What should I do to catch that data? Thanks in advance.

Answer 1

The problem was not about response time. Assume there is a TCP connection opened via AT+CIPSTART, and a request which is 42 chars long, as shown below:

GET / HTTP/1.0\r\nHost: 77.223.129.195\r\n

Before executing one should set CIPSEND to char count. Problem is, \\r\\n are counted as 1 byte each, shouldn't be counted 2 chars. Request consists of 4 chars 42-4 = 38.

AT+CIPSEND=38\r\n

Excluding 2 bytes solved the problem and successfully displayed before the code checks if there are any "+PID,"s.
