Flashing red and green

Hi, I have 3 audio moths which are not recording. 2 were recording before however do not record now. They are all flashing green and red at the same time. I've checked that the SD cards are working and battieries are full. Any help would be appreciated?

Flashing red and green typically means a SD card write error. Check that the SD cards are formatted as exFAT or FAT32, and then switch to DEFAULT. It should then make a recording. Can you confirm which firmware is installed on the AudioMoth.

Replying to

Great. We generally reformat to exFAT before deployment as deleting files doesn't free up the file allocation table on some operating systems (it just hides the files). The other reason for a red and green flash is that the device is configured but has no recording period specified. This means that it can't make a recording in CUSTOM mode (and so will flash red and green) while it can happily make continous recordings in DEFAULT mode.
