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 ?

As stated in Flash App, fimware 1.5 and upper implement persistent configuration (settings remain even when power is lost). Is this feature available only on some hardware version ? I've tried with removing batteries from an AudioMoth 1.0.0 (firmware 1.6.0) and it looses its configuration. ie. continuous red LED and 'fast' flashing green LED whens switched to Custom mode. As I have 1.1.0 and 1.2.0 models, I will try on these hardware versions when I retrieve them.

Hi the Team When analyzing the .wav of one of my AudioMoths I found only 'scratching' sounds. File names, timestamps and file lengths are correct, so just looking at the file list, everything seems normal. I could track back the moment when it ceased to record sound on 3-may-2020 at 06:03:21. The file begins with recorded sounds, then the noise only for 3 seconds, sound again for half a second, then noise the rest of that file and all the subsequent files. Image attached. I suspected batteries and SD card so I made different tests changing batteries and swapping SD cards. Same thing either in custom or default mode. So I came to the conclusion that the problem comes from the AudioMoth itself, possibly from the analog part ? It's an AudioMoth from Round 5 (ID: 24CE97035AA4F124). It's twin brother still runs fine and well and they both have been used in a similar way for one and a half year. Firmware is 1.2.1. Sampling rate 192 kHz and Gain 2. That night was dry with no wind and temperatures in the 9-12 degrees C. As it was the Dawn Chorus Day, another audio recording was being conducted from the exact same place. There was no special sonic event at this time. Are there some other tests I could do ? Or do we have to declare this AudioMoth dead ? Could it be sent for repair, or at least for analysis ? Thanks.

Hi Using the flash application I downloaded firmware 1.4 to upgrade from 1.3. Progress bar goes to a 'firmware successfully installed' but then the AudioMoth is not recognized anymore by any of the apps (flash, time and config). The procedure with the paperclip to go again to flash mode worked so I could triy several times, including with a newly downloaded .bin Had to revert to firmware 1.3 and then I could configure as usual. Could I have missed anything in the manipulations ? Pierre
