I have a problem with my device. The construcion have a six relays conected to ESP8266-12F module. When plug-in connector to 230V Socket and device start-up I see and heare spike on GPIO (especialy IO0 and IO2).
Below I attached short video. This short movie show what is wrong with GPIO when system reset or boot.
Code: Select all
import uos, machine import gc gc.collect()
