My two SCK2.1 do not (or no longer?) charge when off - only when sensing. By this I mean the light indicating battery charging/state isn’t visible/on when the device is off and it is plugged in to a powered USB port.
I’m putting “no longer” in brackets because I’m not 100% sure they ever did - but I thought they used to.
Or is it charging when off… but provides no indicator light?
I feel maybe my assumptions or memory is wrong. I’ll do some further testing and update.
Assuming the SCK2.1 can charge while off and the indicator light should come on…
I first suspected it may have been interference on my part with customizing the firmware but I’ve reverted to SAM 0.9.8 and the problem persists.
Am I correct the SAM firmware controls the battery behaviour, not the ESP?
There’s been some issues with charging in the past. One discussion/documentation I came across notes that “it is probably worth trying with another USB cable”.
I have tried multiple cables and multiple power supplies (e.g., PC, 2A power supply) and none seem to work when the device is off.
I’ll get back regarding further testing.
