I have the same issue. I'm also using an ESP32-C3, and I get ESP_SLEEP_WAKEUP_UNDEFINED (i.e. 0) as the reason for waking after deep sleep, instead of ESP_SLEEP_WAKEUP_GPIO (i.e. 7) when I push a button to wake it from deep sleep. It does wake up from deep sleep, but gives the wrong reason. // In se...

For RTC IOs you can use rtc_gpio_hold_en function. For digital IOs there is a RTC_CNTL_DG_PAD_FORCE_HOLD bit which forces all pads to hold their state. Hi ESP_Igrr, That sounds perfect! Could you please provide an example of how to set that bit on, for beginners like me? Pushing my luck, is there a...

Is there an equivalent comment in the Arduino IDE for ESP32? I'd love to set `RTC_CNTL_DG_PAD_FORCE_HOLD` to be on so that I can hold a non-RTC GPIO as HIGH while in deep sleep.

Or should I just bite the bullet and port everything over from Arduino IDE to ESP IDF?

Hey ESP_houwenxiang / woohooko

I think this is exactly what I'm looking for!!

Holding a non-RTC, GPIO pin's state while in deep sleep.

I know these posts are two years ago now, but did this feature end up getting implemented? I couldn't find it in the documentation.

Thanks so much!
Andrew

Hey davdav and ESP_houwenxiang Thanks for posting details. I have exactly the same problem, I believe. Did you get this working? Here's my setup: I have three non-RTC GPIO pins (16, 17, 18), and I want them to stay HIGH during deep sleep. I'm using Arduino IDE: ``` // Stop doing PWM. ledcDetachPin(1...
