Added a counter that counts low battery level detections.
If there are 4 in a row we go to deep sleep.
The battery sense on the RAK4631 seems to be a bit unstable and may
generate 'false' low voltage readings.
My RAK4631 has been running for 7 days now with this fix.
It did 3 days without it.
I still do not have a T-Echo so on that board IT IS NOT TESTED.
(But I hope it will improve things there too)
Build tested on RAK4631 with battery and their solar panel box.
This is from the log:
17:40:30 102 [Power] Battery: usbPower=0, isCharging=0, batMv=4164, batPct=96
Note that mV reading and Pct is ok.
It does not detect being connected to USB and charging.
Also tested on TBEAM where it seems to be ok.
There still seems to be a problem with the FW for this board that it goes to
sleep for ever after running for a few hours.
However, disabled until someone with suitable hardware can test and report
back.
@slavino and @tschundler would you be willing to try it with your boards?
You'll need to uncomment the following line in configuration.h
// #define BATTERY_PIN 35 // A battery voltage measurement pin, voltage divider connected here to measure battery voltage
