which pin is used to send the infrared signal to the ESP32?

[vilioren56]

Tell me which pin can be used on ESP 32, I tried different commands are not sent, I use the latest version of the library.

#include <Arduino.h>
#include <IRremoteESP8266.h>
#include <IRsend.h>

const uint16_t kIrLed = 18;  // ESP8266 GPIO pin to use. Recommended: 4 (D2).

IRsend irsend(kIrLed);  // Set the GPIO to be used to sending the message.


void setup() {
  irsend.begin();
  Serial.begin(115200);

}

void loop() {
  Serial.println("Sony");
  irsend.sendSony(0xa8305E8, 24, 1);  // 12 bits & 2 repeats
  delay(2000);
  
}

You've told it to use GPIO18.

Look at https://www.google.com/search?q=ESP32+pinout&oq=ESP32+pinout and it should tell you where and what that pin does.

GPIO18 is totally fine to use on an ESP32. So is GPIO4. Make sure you're using a circuit similar to: https://github.com/crankyoldgit/IRremoteESP8266/wiki#ir-sending

  irsend.sendSony(0xa8305E8, 24, 1);  // 12 bits & 2 repeats

I just noticed this in your changed code.
The Sony protocol requires 3 messages to work, i.e. two repeats, not the one you have told it to do.
You want to use:

irsend.sendSony(0xA8305E8, 24, 2);

Also, how sure are you that it is a 24 bit message? The Sony protocol usually only has bit sizes of 12, 15, & 20.

I suggest you read through the code here: https://github.com/crankyoldgit/IRremoteESP8266/blob/master/src/ir_Sony.cpp

There is also a sendSony38() routine. That protocol uses a different frequency. 38kHz. It also requires 4 messages (i.e. 3 repeats).

If you omit the repeat argument, sendSony() and sendSony38() will default to the correct amount of repeats.

thank you to everyone who responded! It worked on pin 4, it's just that it is not correctly marked on the board, the board is marked incorrectly. Fixed the problem by going through all the ports
