I would love to see a light sleep mode. It's the last piece I am missing to create truly energy-saving software for the ESP32.

I understand. What I am looking for is some sort of hibernation or light sleep. Is there a light sleep mode for the ESP32? This is documented for the ESP8266, but this is undocumented for the ESP32. It's only mentioned in the ESP32 Datasheet, Espressif Systems, August 25, 2016.

When the ESP32 wakes up after a deep sleep, it performs a reset. How can I make the ESP32 continue after a wake up? Is there a wake stub example that restores the CPU state?
