How many hours can we work with a fully charged battery?

The advertised capacity of the battery is 2800mA, but I don't trust the technical specification from AliExpress I divide by 2: 1400 mA.
The technical specification of the bluetooth module announces 7.3mA in connection, I round it up to 10mA and I add the consumption of the CL +/- 30mA for a total of 40mA: 1500/40 = 37 Hours

I don't know how long the internal PSION battery can last with the screen on?

Thanks
Olivier

37 hours with one charge is great.

Can you leave an option to users to change the comms setup parameters?

Yes, but i have not tested.
I imagine that in this case you must first change the parameters of the BT module with the AT commands.

Yes I am talking about the bluetooth comms setup with at commands.

It will be complicated, you change a parameter in an AT command, then you go to the CL setup to change it too, and so on.
