This question was asked about the 2015 Senior Soaring Championships

There is a contest in the early part of March Seniors in Florida approx.. 65 glider

If the new update is out will there be a problem if some have the update and some don't.

Flarm Response:


Yes, you are correct, that would be a problem. Devices with the old firmware cannot communicate with the new firmware. From the next firmware release, we will make sure that the protocol changes automatically at the changeover date. Unfortunately that was not possible for this update.

For this contest, I would recommend that nobody updates their devices until after the contest.

Since this update was scheduled before the last one, and the instruction is very specific, my bet is that on April 1st your unit will display a message like "I am not working" and mean it.
