Hello,

I did a flight this evening - everything went out absolutely perfect,  but after flying 15 mins or so I had the problem that there was absolutely no more climbing possible although I was far below max flight level.
When I lowered the drone for almost landing hight, I saw that the height  indicator was below zero and I was only able to climb until zero-then  the drone stopped.
I never had this before. I was updating the flysafe database a few  minutes before the flight, but I think this should should not cause the  problem.
I think it might be a prob with dji fly app 1.5.0 (iOS) which I used the first time for flight. I never had this problem with 1.4.8. Latest firmware is installed.
All other things like gimbal, yaw .... worked perfect.

Did anyone else have the same prob?

Did you restart your iPhone?

Yes I did after downloading flysafe and during the climbing problem!

Yes, somebody also had the same problem:

iPhones are made for non-tech people. iPhone owners are thus not supposed to handle anything technical.

Like a drone!

Hello, I described the exact same problem here: https://forum.dji.com/forum.php?mod=viewthread&tid=253146&page=1&extra=#pid2597782
except that I have an Android phone, not an iPhone.

- We both are in Europe
- We both had just updated the database maybe 15 minutes before.

The symptoms were exactly the same.

I hope this is not something that is going to be frequent.

Should this happen again to me in the future, I'll try not to freak out and test two things:
1) try to manually adjust the maximum altitude setting, in case it got "re-set to zero" internally;
2) try to initiate an automatic RTH and see if it climbs, but in this case caution will be needed, in case the drone starts to fly towards home without climbing first.

Those are good things to test if you ask me.

This was not what caused the incident
Your flight data shows that the drone never reached it's maximum height limit and it was never reset.

I know, but something weird happened, that shouldn't have happened, so we shouldn't assume a normally operating system. It's conceivable that for some reason, the software internally changed the maximum altitude to zero, even though without user input, and without showing it in the settings (or on screen). At least, it's maybe worth a test, in lack of better explanations...

No, it's not.
If your max altitude limit was set to zero, that would have shown in your flight data.
But it didn't.
What showed was something like 1300 ft if I remember correctly.

And if it had reset to zero, there would have been warning messages all over your data to say that the drone was exceeding the max altitude limit.
But there were no messages about that.

Same problem here after 4:00

So the bug - if it is a DJI Fly app bug - is still present in v1.5.1 :-(

I only understand a little spanish, but if I'm not mistaken, the app detected a firmware version mismatch? So it prevented the drone from climbing, and after landing it prevented it from taking off again, until "power-cycled"?
This would at least mean that after a single occurence, the issue should not happen again on subsequent flights. And maybe, since the issue always happened right after updating the FlySafe zones, we should remember to power-cycle the drone after updating the database, and before flying...

For what it is worth a Google translate of the transcript

I don't understand spanish either but was trying to understand what is going on from the automatic english subtitles.
Maybe it was a problem with Fly Safe or app update but here it is the film with the same issue.

I confirm the bug.

In log we can see error message about motor firmware mismatching.

For those curious, I had an issue a few days ago where it also seemed my  Mini2 refused to climb up to a higher altitude at some point.  There  are some similarities (and some differences) in my case.

Similarities include:

• Drone  was flying normally, except: at some point, it seems it just stopped  accepting stick input commands to gain any more altitude.
• Once  it stopped climbing it was at roughly "0" altitude (within a few feet  below or above) but it never got much higher or lower than "0" once the  problem started.
• It was able to hover, and fly horizontally,  as normal, it just would not climb higher to gain altitude, no matter  how I tried.  I hit RTH and it did not climb then either.
• I  had just done an update to the Fly Safe database (and aso updated  Firmware) immediately before this flight (within an hour of flight,  maybe less).
  

Differences include:

• It was cold outside - below freezing.  Some nearby reporting stations indicated -4°C to -6°C.
• I launched from the edge of a high cliff, then flew out over terrain that was much lower.  Most of the flight was at negative altitudes relative to the launch point.   The drone was able to climb up to roughly the "0" altitude of the  launch point, but it would not climb up further -- most critically, it wouldn't go up the  additional ~20 feet necessary to clear some trees between the drone's  position and the safe landing area/RTH point.
• Batteries got  critically low as I kept trying to get the drone to ascend that last 20  feet (repeatedly). I tried to get the drone close to me, even tough trees  were in the way.  I managed to fly between some of the trees in  the last few moments, and got it pretty close.  But with the battery just  about exhausted, the drone crashed in some small bushes about 20 feet  short of the landing point (and below the landing point altitude), on the face of  the cliff.  It is now stuck there, about 20 feet down a cliff, just  beyond my ability to reach it safely, in snow and bushes.  It has now  been out in sub-freezing, cold and wet conditions for 6 days. I may or  may not be able to recover it safely (I will consider attempting  recovery after the snow melts, in the next couple days -- in about 6  months, it should be easy to climb down, but I'm not trying it in snow  and ice).  I'm sure being out in those conditions are not going to be  good for it, it may be (probably is) a total loss.
  

If you are interested in more details, here's the thread: Lost my Mini 2. Not sure why. Too cold?

Good call I was thinking the same thing, I am new to all of this and have seen mine update at least once before going out to fly.

I am still writing procedures for use, will add ' Check for updates, if it updates reboot everything, Drone, Phone, Controller before flight'

Thanks

I know I’m late but I’ve just had the exact same problem now
(31st may 2022)
I updated the fly safe a few minutes before flying and I had been flying fine for 15 minutes and then I was 400 meters away doing some low flying over long grass and suddenly my DJI mini 2 wouldn’t climb!
I tried RTH and that didn’t work it just beeped and said returning but didn’t move
I was on 22 percent and had to sprint across a field with long grass and before I got there I moved it forward towards me because I was still about a meter above the grass and I had my left stick fully up as I flew towards me the drone started going down and crashed into the long grass
Luckily it was fine and by that point I was within 30 meters and saw where it went down but strange it’s still a thing and it must definitely be related to the fly safe being updated before flight
And I restarted my Mini 2 and it worked as normal very annoying and strange
It was only up
I could go down, move around and yaw normally

Another example of the fail to climb after FlySafe DB update... There is a definite pattern here.

Did you reboot the drone after the fly safe database update?

For the sake of adding to this thread, this happened to me too. Was about 500 metres away across the river from my house. Hadn't used my drone in several months so it had requested a firmware update first before flying. Had to get my wife to rush across in the car to get the drone back as it was too low to clear obstacles if I was going to fly it home. It otherwise had a good signal, could fly in every other direction besides climbing/up. Return to home function did not work. Adjusting the maximum height down and up didn't work.
Thankfully it had enough battery that she got there in time or I would have lost the drone.

THAT is an awesome wife to go and chase down the drone for you!  : )
