- Thu Sep 29, 2016 9:42 am #55866 I have a TSOP38238 IR receiver connected to a WROOM02 that is displaying the wrong codes. if I connect the IR receiver to an arduino uno and use IRLib, it works but using the IRremoteESP8266 library with the ESP does not. Does anyone know how I can fix this issue?

- Fri Sep 30, 2016 10:15 am #55913 You must be careful with Arduino libs that have internal timing parameters hardcoded. The ESP8266 is faster, more efficient, and Arduino code must yield to the background RF timeslice every 50mS.

Use a different libraryQ
