Is there a way to check the firmware version so that I know if have to upgrade it?
Hi, There is a readme file for the Flash software here - https://github.com/OpenAcousticDevices/Flash - that describes how you can check the CRC of the current flash contents:
> ./flash -c /dev/tty.usbmodem1421
Flash CRC: 4393
The returned value will match that of the firmware that you have installed. The CRC of the up to date AudioMoth 1.1.0 firmware is 4393.
no being a programmer can someone advise if the command line comes after the C:\ prompt
Yes, you'll need to download the software in the link and run it from the C:\ prompt.
