I bought eighteen AudioMoth 1.2.0, but unfortunately eight of them do not work correctly.
Before using them we updated the firmware from 1.7.0 to 1.8.1 with AudioMothFlashApp 1.4.1. and we used AudioMothConfigurationApp 1.9.1. with the configuration you find in the file: LIFE ALPYR.config.
We use 128GB Sandisk Extreme Pro SD.
When I set the AudioMoth to CUSTOM, the red light stays on and the green one flashes. The AudioMoth does not record anything. As a matter of course I checked the batteries and they are OK. The manual says that the red light stays on if the AudioMoth cannot find the recording period settings. I tried to record by setting the AudioMoth to DEFAULT and it records, but produces files with an incorrect date (01/01/2098). I attach the CONFIG.txt file that I find after the test on DEFAULT. Could please help me?
