Meshtastic Device 1.2.49.5354c49 alpha

Hi,

I think this is the thread that pertains to this issue.
So perhaps it is the different voltage divider ratio than the TTGO?
Thanks

Heltec / lora-32 USB power sensing fixed

Hi ya’ll, I think I’ve probably fixed this one (will be in this weeks build). If you have one of these boards (I don’t currently - will again have one in June) and battery charge level is still not working after I make this new release (friday?), please reply in this thread with a serial log of the first 100ish lines after the device boots in the following two configurations: A battery is connected A battery is not connected

oh sorry! I just noticed this crucial comment here:

Additional context
Manufacturer did not documented battery recognition mechanism. After search and test here what we have:
battery_pin = GPIO37
ratio of voltage divider = 3.20 (R1=100k, R2=220k)

Describe the bug Due to lack of battery recognition and voltage reading hel…

Which I bet explains the problem you are seeing on your board. I think I’ll have to make a HELTEC_V2 hwmodel and use different R scalings (and different GPIO) for the board you have.
