I received the audiomoth at the end of May. As I had someone from the bat conservation trust arriving I thought it would be a good time to set up. The instructions for set up are clear and although the device was placed three times in a known bat locality I did not get any files recorded. The green light flashes but the red light will flash briefly presumably to indicate a begining of a recording duration. I have also followed the instructions on the British Bat Survey webpage and played the tone but getting nothing. The batteries are fine. The SD card is he one supplied with the device and it is correctly formatted. It is probably something daft I am not doing. Any idea?
I have seen two posts on this forum regarding rechargeable batteries. I am currently thinking about investing in purchasing 1.2V Envee 2800mAH rechargeable batteries, as I will be creating much lesser electronic waste compared to purchasing regular alkaline batteries. Apart from operating at the lowest threshold for the Audiomoth's, has anyone used rechargeable batteries for a while now? How does it affect the performance? Did you have to replace them every few days? Any issues with writing data to the SD Card?
