I noticed that there is an iOs app for setting time on AudioMoth using a chime but that it requires firmware version to be 1.5.0. Where do I find this firmware version to evaluate it? Thanks!

The case was tilted back just slightly for a small amount of water to collect and cover the microphone opening on the case.

I have my AudioMoth configured to sleep 5 seconds and record for 55 seconds from 4am to 8am every morning. I end up with 240 files to evaluate each taken every minute. However, today, for the first time, I had files of 5.3 MB size from 4am to 5:30am and then every file after 5:30am of completely varing sizes and some zero bytes. When I load the files after 5:30am, they are all different lengths of time.
