In my GPS tracker program for the AB02S I wanted to use the RGB led for my own purposes, so I set
LoraWan_RGB=0 and manually configured the led to glow red for error conditions.
All this worked perfectly, but when I took it outside on a cold day to test the tracking, the RGB led started flashing unexpectedly.
It seems to flash when Lora radio communication is happening.
This isn’t a problem for me as the finished device won’t get cold, but I thought you might want to know about this.
To reproduce this I put it in my freezer (in a plastic bag)
