Trying to use an AudioMoth 1.2.0 that has been used troughout year 2021.
With switch on USB/OFF, when the 3rd battery is inserted, LEDs turn on: fixed red+ flashing green.
Attempted to set the time by playing chime from mobile app. Nothing happens.
When the switch positioned on CUSTOM, both LEDs go off.
Switch repositioned on USB/OFF or DEFAULT, LEDs still off.
Left for the the night with the switch on USB/OFF, next morning the batteries are completely drained (0% displayed on the charger).
This AM was configured with the same paremeters as a couple of others that are all behaving as expected. SD card has free space and tried with another SD known to work fine.
Is this a known behaviour ? Am I missing something ? Any clue to solve that ?
It would be worth trying to put it into the bootloader mode manually by connecting USB power (without batteries) whilst holding a paperclip on the programming pins. It won't show any LED in this mode but you will see it connect within the Flash App and that will then allow you to update the firmware.
