Where can I find the information about Heltec ESP32 LoRa V2 RTC GPIOs?
I need this information to be able to make a sketch with External Wake Up from Deep Sleep.
The Espressif ESP32 Dev Kit V1 has RTC to GPIOS: 0,2,4,12,13,14,15,25,26,27,32,33,34,35,36,39
For the Heltex ESP32 LoRa V2 I tested some pins as 36, 39, etc… and they didn’t work for External Wake Up from Deep Sleep.
