Well they're not 'Arduino' functions but ESP-IDF functions are accessible within the Arduino framework. They will work fine in Arduino IDE, for example. I forgot to mention you'll need this though: #include "driver/rtc_io.h" Just tried with your advice on GPIO12, no change. With 12 ws2812b neopixel...

Drive the data in pin HIGH on sleep. //on wakeup rtc_gpio_hold_dis(rgb_data_pin); //on sleep digitalWrite(rgb_data_pin,HIGH); rtc_gpio_hold_en(rgb_data_pin); //keep it high in deep sleep I guess you'll need to make sure it's a RTC GPIO. Thank you for this remark. Are those commands working on ardui...

Hi All, I'm working on a little project involving an ESP32 devboard, powered on 4*AA 2400mA NiMH batteries, and equipped with neopixels (12 of them), and a capacitive soil sensor. The idea is simple, have the best autonomy with those components. In order to do so, the ESP32 only wakes once every hou...
