FLARM uses a rolling release cycle, requiring an annual update. Each update can be applied anytime during a rolling one year period. This makes it easier to align FLARM firmware updates with the yearly aircraft maintenance. It is also in line with the maintenance care that a safety system requires. Each firmware version is valid for at least 12 months from the date it has been downloaded, after which it will stop to function.
As the update cycle is individual, no generic information is sent out on individual firmware updates and expiration dates. If you want to be notified about major and important updates, sign up to our newsletter on https://flarm.com.
We release new firmware updates normally at least twice per year. This is however not related to the 12 months update scheme. If we do changes that affect the interoperability between devices, this will be handled automatically by the firmware, and there is no need to update the firmware outside of the 12 months firmware validity. Most firmware changes are related to special configurations or developer requests, so normally it's advisable not to update outside the normal update scheme.
