We've released updates for the AudioMoth Flash App along with updates to all three official firmwares (Basic, USB Mic, and GPS Sync).
The Flash App can now use USB HID flashing to apply firmware to AudioMoths. This new flashing method is more robust than the previous serial flashing. The firmware updates add support for this too.
As well as new flashing methods the app is now able to operate with more than one AudioMoth application open. Previously the AudioMoth Flash App, Time App, and Configuration App would interfere with each other when all attempting to communicate with the same device.
Is there somewhere to see what changed with the GPS sync?
