ESP32 Forum

"I'm working on an ESP32-C6 project with ESP-IDF (version 5.4.1) to implement an IR remote receiver and transmitter for controlling my AC. The provided esp/v5.4.1/esp-idf/examples/peripherals/rmt/ir_nec_transceiver example is helpful for understanding RMT, but it only supports the NEC protocol. Since I'm unsure of my AC remote's exact IR protocol, I'm looking for guidance or a code example that can act as a universal IR receiver (to learn the signal) and transmitter (to send it) for common AC units. Any assistance would be greatly appreciated."

Arduino-IRRemote is very easy to use to identify the signal family. Once you know the protocol, I'd recommend using an ESP specific RMT-based IR library (eg Freenove, IRremoteESP8266) to get the best performance.

Thank you for your suggestion. The code is now running properly, and everything is working as expected.
