Hello,

could you please attach full flight log?

This is not normal for sure, but it depends at which time the event is occurring. Is it when you are really flying?
Or when you are accessing the unit from your computer.

If it is second case then this could be caused by a communication problem between unit and computer. But if it is first case then it will have an impact on all GeoLink features.
For example if hitted by electrostatic discharges it could temporarily disable communication between GeoLink and Spirit unit. And this would then mean that it would randomly not work.

This event could be displayed always when GeoLink data transmission to unit are missing for over 2 seconds.

If there is event with Red triangle in the log then it is important error and Flight log will save to the unit. So then you can view it as Previous flight.
Unfortunately I have no log file from you, only this screenshot. So I can't tell you any other detail.

First I recommend to verify if it is happening really during flight or just when you are accessing Spirit Settings.

Do you have the latest Spirit Software and firmware installed?
