Has anyone else run into an issue after adding the lines esp-idf the WiFi status LED no longer works properly?
Just troubleshooting one of mine and realized none of them are flashing the WiFI connection LED anymore when they lose connectivity. On my ESP32 boards the LED is internally connected to GPIO2 and can’t be changed from that GPIO.
status_led:
pin:
number: GPIO2
inverted: true
