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.
The behaviour is the same when connected to a PC with the switch on USB/OFF. Solid red and flashing green.
LEDs go off wben the switch is changed and do not come back when switch is returned to USB/OFF position.
AM is not seen by the config app nor by the timesetting app.
This AM was used in March, last time on 2022/03/22 and the recordings were fine. Installed at home in a container and in protected place.
It was reconfigured a week/ 10 days ago and it seems everything went fine too.
Since then it has been kept indoor and it looks 'as new.
Is it possible to connect to the Config App with the switch in any position? This sounds like a hardware problem. Are there any obvious signs of corrosion?
