Not crash or flyaway - but what happened? Can we tell, or not?

[OurAngryBadger]

Was standing directly under Mavic 2, about 50-70 feet below it. Direct line of sight to the drone, no obstacles or power lines. The image feed went completely black and white and got the "no image signal, returning home" error. I still had full control of the drone with the sticks, and was able to guide it safely to a good landing spot. Before landing, I did try to move around on the ground, and also bring the drone closer to see if I could regain the signal, but it just absolutely refused to. I was using the smart controller.

Is there any way to tell what might have happened? This has me concerned for future flights that my mavic 2 might be defective.

I see early on in the log there was a cell deviation warning --- but that was early in the flight many minutes before the problem happened. I strangely don't see any other error messages in the log about the signal loss?

Nothing is shown in any of the logs that you had connection problems ... My guess is that Go4 crashed or at least some functionality did. And a battery deviation have no influence on the connection. Either can't I see anything about the "no image signal, returning home" error you said you saw.

The Go4 didn't outright crash, I only lost the image feed. I could oddly enough still see the telemetry data (?) update as I was flying it and the map position update. This was my fear that the log wouldn't produce anything to help us out.

Could a loose connection between the camera and drone cause this? I have less than 30 flights on this thing and no crashes so I'd be sad if there's a loose connection.

On another note... should I be concerned at all with this battery and the cell deviation problem?

Can't help out regarding loose connections to camera & possible effects coming from that unfortunately ... But looking at just this flight & the battery deviations, Airdata shows a very healthy battery, it couldn't have been a deviation warning coming from the Smart Controllers battery?

This from the MP2 battery ...

That situation has been reported a number of times with the SC. It seems to be an app problem on that platform.

Happens frequently to me - but only when I first start up has never happened in flight.

I always power up the SC first and then my M2P....if I do it in reverse order, I sometimes do not get the video feed. Go figure.

I would second that. Power on SC first then drone. And if you make multiple flights power cycle both devices.
