I purchased 2 AudioMoths V.1.1.0 (Round 9) which I received on March 10, 2020. Everything worked well until a few days ago with one of them (my AudioMoth AB-1) which just started producing 0 octet files. Two days ago I flashed it and reconfigured it, and made a shot test to check recording which it did - see in attached file. This morning, I brought both of them in to download the recorded files and found out that AudioMoth AB-1 has produced 0 octet files during the night. AudioMoth AB-2 is still working well.
I would appreciate some help to resolve this issue.
