<![CDATA[M5stack CoreInk RTC/deepsleep not working on UIFlow2]]>Hi

I cannot make deepsleep with timer wakeup work even in its simplest form on the Core Ink. Considering this is a e-paper device I would say its one of the most basic features they would test during development.

A simple use case is a bitcoin price ticker that downloads once an hour or something. But not even this is now realistic on battery since deepsleep doesnt work.

Did anyone else make it work with UIflow2?

Plugged into USB it will wake instantly after sleep with timer reason set. It does not wait for timeout.
On battery it never wakes up. Powerbutton will wake it with reason power button.

hmm, works for me. Tested both: power off and deep sleep.

I created an example which might help you. You can find it in the UIFlow2 Project Zone: M5CoreInk_PowerOff_DeepSleep_Test_UIFlow2.3.2

Thanks
Felix
