RAK2171 battery values?


I want to setup an alarm to know when it needs to be charged. Unhappy tracker returns an absolute value and I’m unable to determine scale with real state of battery.
I checked all documentation about it on rak website but can’t find anything about it.
Would someone know how to interpret the numerical value returned by the tracker for battery level ?



Hi @vincen,
You have 1 byte for the battery status, check the documentation here:

You should interpret the battery as 20 - 20%, 65 - 65%, and so on.
