I have two things about the Sleep Mode:
The Display sends no answer to the MCU if "sleep=0" is sent and the Display is awake.
The same applies the other way round:
If the Display is in sleep mode, it doesn´t send an answer to "sleep=1".
So it´s very hard to handle the sleep mode in the MCU program.
I would even like to see an Information like "going to sleep mode" as an information sent from the Display or "command not accepted, in sleep mode" as a reply from the Display.
thanks! v0.30 will fix it.
Sleep, thup and thsp has gone through several changes since 0.29.
