Just got my trial AudioMoths and don't understand the LED flashes that I am getting. I double-checked the configuration and this seems fine (8kHz sampling rate, schedule 00:00 to 23:59, gain 'low').
- one unit is flashing green every 2 seconds for 7 repeats, then a quick long green flash. This appears to be signaling a full micro-SD. I reformatted and it is behaving like the one below.
- one unit is flashing red at a similar interval, then after 5 repeats a short green flash and a pause of about 4sec, then red again.
if this one is switched to 'default' it resumes the same flashing sequence as above.
It would be good to update the 'getting started' with a full description of LED status indicators.
Just tested several Audiomoths in different housings. It is clear that disabling the LED doesn't have an impact on the clicks mentioned above. Like Andy stated, it is likely to be the writing to the SD cards. Unfortunately those clicks are much more present when put in a case. The plastic bag is intermediate and without any protection it is negligible.
Recording in tropical conditions require adding some housing. We hope this can be solved in the next batches....
