Sleeping State Suggestions #22

Open adamsimecka opened 2 years ago

adamsimecka commented 2 years ago

The device does not appear to automatically go into PretendSleeping if the device is in a deep sleep mode. This means that if the device is sleeping and it is then plugged in, the device does not charge (according to Blackcofee). If it is possible, I believe we should trigger PretendSleeping as soon as a charging voltage is detected - although that might be a challenge since the device is in deep sleep and may not be able to execute those instructions from that state.

Similarly, the device does not appear to go into a normal deep sleep automatically from a PretendSleeping state. Meaning, if I am charging the device and it is in the Pretend Sleeping state, but then I unplug it without waking it up, it seems to remain in the PretendSleeping state which likely will cause severe battery drain.

While in normal deep sleep all keys in column 1 will wake the device. While in PretendSleeping state, only the reset (*) key will wake the device. This can be confusing for the user if there are different waking rules depending on the state.

A suggestion to the issues above, would be to map one of the physical buttons to force it into a deep sleep like the way it is done on the LilyGo T-display factory test example. I don't know if that would solve the problem of the battery supposedly not charging while in deep sleep.

Aye, it doesnt need to pretend sleep, we should just remove that and have it actually sleep

Yes. I completely agree. The original issue was during a time that Blackcoffeexbt was having issues with charging while sleeping. I believe those have been resolved. So, we should not need pretend sleeping any longer.
