Anyone know what this means??

I see this too and not sure either. Signal STR still looks good when it happens too. Maybe it is just switching freq in the band and that is what log shows when it does.

Temp loss of signal - prob a second that was so quick you never noticed in flight

Maybe, but zero signal errors in the log when that shows in log too. Also just feet away from RC. I have seen hundreds of signal errors and disconnects and not seen that in the log either. So who knows.

I wish DJI would chime in and let up know what it means. It seemed when I was flying, my mavic seemed to stop for a second. So I dont know. I wasn't going fast when it happened and my signal was great all throughout the flight.
