Hi Alex, thanks, I will contact LabMaker. I have been trying several different SD cards, such as SanDisk extreme (256 Gb, 64 Gb and 32 Gb), and Samsung Evo (64 Gb). Have read many recommendations of SanDisk extreme 32 Gb, wherefore I bought it. Did not work with any of those. Thanks again, Diandra

Hi Alex. Thanks for your response. We already flashed the AudioMoth before and it did not make a difference. We ordered the Audiomoth at LabMaker last year. What else could we do? All the best, Diandra

Hi Alex, thanks so much for your response. I have done as you told, I connected the USB cable without batteries, but microSD card inserted. I do not get a red flashing but a slow, simultaneous flashing of both red and green. I doublechecked, no recording was found on the SD card. All the best, Diandra
