ESP8266 Community Forum

- Wed Apr 04, 2018 1:19 pm #75143 I converted a working nRF24l01 RX sketch from the Arduino Uno platform to the ESP8266 and in my serial monitor I see the following and I am not sure how to troubleshoot it. The program compiles fine.

wdt reset

- Wed Apr 04, 2018 4:18 pm #75149 wdt reset is normally caused by some process in the loop taking too much time like something waiting for the nRF24l01 before proceeding.

On the esp8266 it is important that the wifi underlying processes get a chance to execute. This happens naturally once per loop or you can explicitly put small delay or yield functions in the loop.
