Core Ink Wake Up button from Deep Sleep
alexylem last edited by
Can't get my M5 Core Ink to wake up from deep sleep using a button :
esp_sleep_enable_ext0_wakeup(GPIO_NUM_5, LOW); // EXT buton esp_deep_sleep_start();
It goes to deep sleep but does not wake up from button. It does wake up from an RTC timer though.
I also tried holding power pin without success:
gpio_hold_en((gpio_num_t) POWER_HOLD_PIN); gpio_deep_sleep_hold_en();
Thanks for your help!

only so called RTC_GPIOs can wake ESP32 from deep sleep. Unfortunately GPIO_NUM_5 is not one of them.
Please check out page 15 - Pin description of the ESP32 datasheet.
