Remotely wake up ESP32 from Deep Sleep
Posted: Wed Feb 28, 2024 6:33 pm
From all that I have read there seems to be only four(4) ways to wake an ESP32 once it is in Deep Sleep mode:
single GPIO, multiple GPIO, touch and timer.
What I would like to do is remotely wake a MCU from Deep Sleep.
Does anyone know how to do this or is it even possible? I suspect the answer will be No!, but perhaps someone knows of a way to do this.
In my case my MCU's are only about 20 ft apart so I will be able to 'hard wire' the trigger from the SENDER mcu to the RECEIVER mcu.
All suggestions or comments are most welcome.
Thanks!
