Hi,

Thank you for your response!

I do see the power source voltage that you mention, however, it always reads 94 mV.
It does not change when I connect or disconnect the USB cable, or after charging.

Here is the answer from Asset Tracker developers

The firmware doesn't provide battery status / percentage. However, in object 3 (device obj) we set voltage level.

[Power Source Voltage 307]

More information can be found under https://docs.nordicsemi.com/bundle/ncs-2.7.0/page/zephyr/connectivity/networking/api/lwm2m.html

Kind regards,

Hello,

Does the device show correct sensor data for e.g. temperature in Coiote? What does the logs of the Thingy:91 say, could you please provide these?

Thanks.

Kind regards,
Øyvind
