Hello All,

I've been having an issue with my Air 2s. Many times during Return To Home, it will stop, climb a few seconds, proceed going forward again, then repeat the behavior over and over.

This happens in all lighting conditions, all temperature conditions, and all humidity conditions.

At first, I thought that my after-market propellers may be causing the issue, but re-installing the DJI propellers made no difference.

Sometimes it helps by putting the drone in Sport Mode (disables obstacle avoidance), sometimes it doesn't.

Does anyone know what the problem could be?

Thanks

Several thoughts occur to me.if
1) RTH has been considered to be a separate flight mode and it may switch OA on, have you tried literally switching OA off in the app?
2) are the OA lenses clean?
3) try taping over the forward looking sensors so that they literally can not see. I don't know what problems that might create within that drone so exercised caution when first launching the drone.

Hi,

From your description it seems that the OA senses a false obstacle.
This will stop the forward motion, climb few meters and start flying forward again, repeating....

In RTH the OA is automatically set to ON, even if OFF selected in the menu.
Selecting Sport mode does not do the trick, as in RTH OA is always ON.

If this happens in all lightning conditions than its a serious problem, but most of the time it only happens when flying into the sun direction, or many reflection into the lens.

Try again and test in several RTH headings.


If you like post your flightlog for this issue.
cheers

What you've described is typical of obstacle avoidance being triggered by a low, bright sun.
Was the RH into the sun?

Selecting sport mode makes no difference, because no matter what flight mode you have selected your drone will always RTH in RTH mode.

I have not tried turning OA off completely, the OA lenses are clean, and I have not tried taping the sensors.. I'll give that a try and post an update after my next flight. Thank you

Sometimes RTH faces the sun, sometimes it does not. This behavior even occurs at night. It happens in all lighting conditions.

JJB* mentions in post 3 that switching OA off, presumably via the app, will have no effect because it is always on during RTH irrespective of any setting.
Taking that to be true I think taping over the sensors is your only other physical test.

Incidentally the flight log might indicate if the drone is responding to a detected object so posting the flight log is a good idea. But I have never really paid attention to that in logs since I very rarely use OA at all and don't have an air drone of any sort.

Thanks for all that info. Next time I fly, I'll do a flight with multiple RTH headings and post a log

Two simple ways to confirm whether it is caused by Obstacle Avoidance is ...
If you see this happening again, cancel RTH and fly the drone yourself.
Change direction 10° or 20° and see if the issue continues or only happens on one particular heading.
or
Disable Obstacle Avoidance in your app settings and see if you can fly the drone normally on the RTH heading.
