Dear friends,

We have used a number of devices (26) in a field experiment, and after tagging all resulting files automatically with a code routine, I've realised that the file headers of all them contain the same AudioMoth ID, which does not correspond to any of the devices we have.

I attach a screenshot of the header of a random file as shown in Audacity. No matter which software/recording I use to read them the ID in the message is always the same (whereas the rest of the details, such as date, gain or battery seem to be consistent):

The device ID we keep getting in all files is: 0FE081F80FE081F0

Any idea of why we don't get the real ID of the devices in the header? It would be a very convenient feature to help us tag every recording with a unique code.

Many thanks!
