A new firmware update has been released for all FLARM devices. The new firmware improves the Alert Zone (AZN) alarm behavior, adds a new test for audio out (for installers), and increases the maximum allowed supply voltage to 32 V in PowerFLARM Core, to support additional aircraft types.
Make sure that your FLARM device is updated at least every 365 days as part of the aircraft continuing airworthiness. Failure to do so might render the device inoperable (until it’s updated).
The new firmware, together with the release notes, can be downloaded here.
