Recording issue, fails to start recording
Hi there, I have managed to use many audimoths and have got them to record on schedule.
I now have two that just fail to start recording. I have done software updates, firmware updates and even manually flashed the firmware too. It seems like something else is wrong. Tried different memory cards, all formatted first, new batteries etc. Once set in custom mode, just get the green flashing led approx every 2 seconds. At the time of scheduled recording, it give a single long green flash then returns to the two second interval flashing led. I wondered if you have ever come across this, these units have been used previously in the field. I was asked to try and get 6 units working. I have now got 4 working but these last two are being stubburn. Many thanks, Sean
Hi Sean, Flashing both LED together indicates an SD card write error. I wonder if this is what your AudioMoth is doing and the red LED has also failed. When you reflash the firmware using the USB HID route, both LED should light for about 2 seconds whilst the AudioMoth restarts. If you only see a green LED then, there is definately a problem with the red LED. An SD card write error can be caused by SD cards taking high current (we only use SanDisk Extreme cards), low batteries, or a hardware issue due to corrosion. It sounds like the third cause might be the problem here.
