M5StickCPlus2: want to know how to wake up from deep sleep
-
Basically, I'm trying to develop something like Amazon Dash Button, which works with local wifi.
In order to do so, power consumption is very critical because M5StickCPlus2 does not seem last long without power charger.
So I'm trying to deepSleep from Power Class (https://github.com/m5stack/M5Unified/blob/master/src/utility/Power_Class.hpp) to save power.
But I cannot figure out a way to wake up at will (not waking up in the period I designate), by pressing btnA, for example.
Or perhaps if the btnA works as a power button so that pressing it powers it up.
Could anyone help me out?

@felmue Thanks! It seems to work well.
