IR - Transmit Result differs from Received Result

[lattitude]

I am using a Send and a matching Receive IR Modules using 2 Arduino Uno. I am trying to replicate a Remote using the Arduino. The Remote generates the following on the monitor

“Protocol=NEC Address=0x80 Command=0x4 Raw-Data=0xFB047F80 32 bits LSB first Gap=3276750us Duration=67500us”

But the Receive Module generates this

“Protocol=NEC Address=0xDF Command=0xFE Raw-Data=0x1FE20DF 32 bits LSB first Gap=3276750us Duration=67850us”

This my send code

#include <IRremote.h>

IRsend irsend =2;

void setup() {

  Serial.begin(9600);

  Serial.println("IR Transmitter Ready");

}

void loop() {

  // Send a sample NEC code (e.g., 0xFB047F80)

  irsend.sendNEC(0xFB047F80, 32); // 32-bit NEC code

  Serial.println("IR Signal Sent");

  delay(2000); // Wait 2 seconds before sending again

}

This my Receive code

#include "IRremote.hpp"

#define IR_RECEIVE_PIN 2

void setup() {

  Serial.begin(9600);

  IrReceiver.begin(IR_RECEIVE_PIN, ENABLE_LED_FEEDBACK);  

}

void loop() {

  if (IrReceiver.decode()) {

    IrReceiver.printIRResultShort(&Serial);

    IrReceiver.resume();

  }

}

Can anyone help here?

Got it - Sorry -

You are using two different library versions which handle the signal differently. Update the transmitter library to 4.3 version and use the library example simplesender.ino for correct syntax.

kmin - I changed the libraries to match and it still did not work, however I did notice in another post that they had used ‘irsend.sendNECRaw(0xxxxxxxxx, 32);’ and when I changed the send to NECRaw it worked, So thank you for your assistance in this matter as it is appreciated.

Yep, if I remember well they flipped the NEC protocol between those libraries, so you need to have both on new library and get new received signal.
