LilyGo T Call SIM800 software battery disconnect

Open daniel571 opened this issue 3 years ago • 2 comments

Hello, I have LilyGo-SIM800L-IP5306-20200811 Whenever I insert a charged battery the board start to run. I want to be able to stop the discharge from the battery to save its life. I tried by SW to stop the boost, I tried to press long press on the reset button and I tried to press two times in 1s and the board always return to run and waste battery.

How can I smartly disconnect the battery? Is there a way to tell the IP5306 to stop the boost until next press the reset button?

Thanks

Hello, I have the LilyGo-SIM800L IP5306 and it only comes up by pressing the reset button after changing the Lipo (18650) battery. Now I have designed a waterproof case for the T-Call (with external battery compartment) and want to boot it automatically after replacing the battery. Is this possible?

Thanks

Afaik it is only possible with the two T-Call version with AXP192 but not with the IP5306!
