IRRemote on ESP32 modifies const array elements

Projects Programming

Hey y'all, I've had an Arduino Uno turning my AC on and off for a while now and I decided to switch to ESP32 to make a wireless system.

I wrote the simplest version of the Uno code to use on the ESP32 as a starting point and there is already an issue I can't solve.

I am using "sendPulseDistanceWidthFromArray" from the IRRemote library with specific values for my AC because this was the only way it worked when I first wrote the program.

The command looks like this

IrSender.sendPulseDistanceWidthFromArray(38, 3000, 1600, 400, 1100, 400, 400, tRawDataOn, 112, PROTOCOL_IS_LSB_FIRST, 0, 0);

And this is the tRawDataOn array variable

const IRRawDataType tRawDataOn[] = {0x126CB23, 0x7022400, 0x0, 0x4200};

After this failing to work, I attempted to decode the signal with the same receiver I used to get the codes from my remote and saw the following:

The remote's RawDataType array looks like this

uint32_t tRawData[]={0x126CB23, 0x7022400, 0x0, 0x4200}

When received

However, the ESP32's RawDataType array looks like this

uint32_t tRawData[]={0x126CB23, 0x0, 0x7022400, 0x0}

I'm trying to figure out what is causing this array shift or how to mitigate it.

This is the complete file

Code 
#define IR_SEND_PIN 4
#include <IRremote.hpp>

const IRRawDataType tRawDataOn[] = {0x126CB23, 0x7022400, 0x0, 0x4200};
const IRRawDataType tRawDataTimer[] = {0x126CB23, 0xF022C00, 0x340, 0x9500};

float temp = 30.00; //Testing

void setup() {
  IrSender.begin();
}

void loop() {
  if(temp > 28.00){
      IrSender.sendPulseDistanceWidthFromArray(38, 3000, 1600, 400, 1100, 400, 400, tRawDataOn, 112, PROTOCOL_IS_LSB_FIRST, 0, 0);
      delay(2000);
      IrSender.sendPulseDistanceWidthFromArray(38, 3000, 1600, 400, 1100, 400, 400, tRawDataTimer, 112, PROTOCOL_IS_LSB_FIRST, 0, 0);
      delay(5000); //Testing
  }
}

If you have any suggestions, even if they aren't a fix, please let me know. I am open to changing the whole program as long as it functions properly with my AC.

Not what you ask, but have a look. There is huge number of ac protocols decoded, ready to use.

I'll check it out and maybe refactor, thanks for the rec.
