Re: ESP32-S3 RMT RX truncating IR signals - need help


I can't immediately find any fault with the code. Do you have a LA or scope trace of the signal you're receiving?


I don't have a logic analyzer available right now, but I can provide more context. I'm transmitting RC6 code 0x2401 using an Arduino with IRremote library. The transmitted signal ...

The issue is that my transmissions are being truncated - I should get 22-24 symbols for complete RC6 frames but I'm only receiving 19-20 symbols before it cuts off. I've tried increasing buffer sizes ...
