Has anyone else had this message
BRAKING NOW! RETURN STICKS TO MIDPOINTS FIRST.

What does it mean

Never seen that one, sorry and good luck.
Regards,
-d.

wonder if its related to CSC setting where the there is an option that says the sticks "innet/outter BREAKDOWN only"

This message sounds to me like the Mavic is braking on its own (e.g. maybe OA is causing a stop) and it wants you to center the sticks so you are not fighting this action.

check the log and see what happens on that flight? might be best to calibrate the controller just in case

Yes, I had those warnings for the first time today. The Mavic was flying into the direction of the sun and OA was tripping. Did not see it on the screen, only noticed it in Healthydrones.

It's the message you get when the Mavic senses an object close in front and applies braking.

No objects 300ft in the air !

Probably a brief false alarm or you were flying toward the sun.

Invisible alien spaceship in its path?

Then I can think of three possible explanations:

1. A bird or something else flew in front of your Mavic

2. The sun triggered the OA false alarm (this is common when flying into a low sun)

3. Completely false alarm

Not happened for a few days so must have been a blip in the system or like you say the sun or a bird,
Thank you guys.
