Getting (EMI) Electromagnetic Interference with "release/v4.4/examples/peripherals/gpio/generic_gpio"

Postby Kunjan » Tue Nov 23, 2021 10:07 am

Since three months I am trying to resolve EMI (Electromagnetic Interference) with gpio example. I connected 4 relays with esp32 and operated those relays with switches(Load). While switching ON the FAN which is part of my main switchboard then connected switches also randomly getting ON/OFF.

Please help me to get rid out of this.

What does your hardware look like; are you trying to power the relay coils directly from the ESP32 for example? EMI typically is not a software issue, but it would also be good if you could post your code as well.
