Batteries in my devices have all been expiring quicker than I’d expect, but I had no idea why.
I recently started working on a new device and noticed it would keep changing to Spread Factor 12. I then looked at all the existing devices and found they had all changed to Spread Factor 12.
Hunting around a bit more, I found you can edit the data rate (DR) for ADR enabled devices in the service profile by setting max and min DRs. I have never edited this before and have always left both values as their defaults of zero. When left at the default of zero, I am assuming this will make the devices transmit at SF12? If that’s the case, should the defaults be zero and five?
