A new version of the AudioMoth firmware is now available. This is a small update which improves how the AudioMoth handles short sleep durations and WAV files close to the max file size. Make sure you're using the latest version before making a post in the support forum, as the issue you're having may have been fixed in a subsequent update. Download and apply the firmware to your devices using the AudioMoth Flash App.
