ESP8266 Community Forum

- Wed Feb 21, 2018 12:10 pm #74105 To add a little feature on already done Arduino project I'm using ESP8266-01 module. To trigger the event, it says I need to make a POST or GET web request to: https://maker.ifttt.com/trigger/overhea ... TTi0oo0vRl. (Key changed)
How can I do this by using AT commands of ESP01?
I tried:

Code: Select all#include<SoftwareSerial.h>
SoftwareSerial ESP(3,4); //rx tx
#define DEBUG true
String Host_name = "*****";
String password = "********";
char inv='"';
void ResetConnect();
void triggerIFTTTAPI();
void setup() {
  ESP.begin(9600);
  Serial.begin(115200);
  pinMode(7, INPUT_PULLUP);
  Serial.println("Ready press button");
}
void loop() {
  if(digitalRead(7)==LOW)
  {
    triggerIFTTTAPI();
    Serial.println("End of program");
  }
void triggerIFTTTAPI()
{
  String start="AT+CIPSTART"; //command to establish connection
  start+="=";
  start+=inv;
  start+="TCP";
  start+=inv;
  start+=",";
  start+=inv;
  start+="maker.ifttt.com";
  start+=inv;
  start+=",";
  start+="80";
  start+="\r\n";
  sendData(start, 3000, DEBUG);
 
  String cipsend="AT+CIPSEND=100";
  cipsend+="\r\n";
  sendData(cipsend, 2000, DEBUG);
 
  String request = "GET /trigger/overheat/with/key/c8OXo1RPwep9TTi0oo0vRl";
  request+=" HTTP/1.1\r\n";
  request+="Host: maker.ifttt.com";
  request+="\r\n";
  request+="Connection: close";
  request+="\r\n\r\n\r\n\r\n";
  sendData(request,7000, DEBUG);
}

String sendData(String command, const int timeout, boolean debug)
{
  String response = "";

  ESP.print(command);
 Serial.println(command);

  long int time = millis();

  while ( (time + timeout) > millis())
  {
    while (ESP.available())
    {

      // The esp has data so display its output to the serial window
      char c = ESP.read(); // read the next character.
      response += c;
    }
  }

  if (debug)
  {
    Serial.print(response);
  }

  return response;
}

}


I didn't write code for connecting ESP8266 to WiFi as it automatically connects.
But I had no luck. I might just be plain wrong about this.
What is the right way to do this?
Thank you.
