Hello @nxt518 Have you found a better way?

Since they all have to be low to wake up do you mean the last pin to go low? I don't think that would be stored in any registers. Ok, well it sounds logical what you say, but I find it strange that this is not mentioned in the description of API esp_sleep_get_ext1_wakeup_status it mentions that it ...

If the mode is ESP_EXT1_WAKEUP_ALL_LOW then don't you already know that they are ALL LOW? Well, I need to Know which pin cased the wakeup when going LOW. I know I can do it the other way around using "ANY_HIGH" but that's the way the hardware is setup... and esp32 documentation does not mention tha...

Hello, I am configuring 2 pins (GPIO32,33) as ext1 wakeup source from deep sleep with mode = ALL_LOW (i.e wakeup when both pins are LOW), the chip wakes up as expected when the configured pins are both LOW, but I have a problem I always get 0 as a return from esp_ext1_wakeup_status() trying to know ...
