Unable to take control - No bug, but technicall issue

Chino Chiang

Hei, I flew the same mission many times but after this week dronelink is unable to take control aftear elevating 4-5 metters when i start a mision. Doesnt matter which plan I choose or if I create a new plan, I get the same errror: unable to take control (without saying why?). I have been flying in a restricted area but I have a valid permit (and also imported to the aircraft). I have also accepted the liability conditions.

I'm flying a dji mini 2 in IOS(16.5.1) with drone link 4.6.0(259) kernel 4.6.0. I have dji fly 1.10.6(777) 

  1. The flight mode switch is not set to P / Normal  - No, is set to N(P)
  2. The drone is at or near the max altitude setting in the firmware - No. Flying at 7 metters, limit to 40
  3. The drone is at or near the max distance setting in the firmware - No. it doesnt take control even thought is at 200 m from the starting point
  4. The drone is in or near a no fly zone which has not been unlocked - Zone unlocked
  5. Multiple flight mode has not been enabled in the firmware - Not sure how to check that
  6. The drone does  not have a valid GPS fix, even for a brief period of time - It have. more than 12 satelites available

Also. I delete the data cache data from DJI fly, but nothing

Also, I can flight inside of dronelink and DJI fly app. Is just the mission who doesnt work...

Question: Where can i see why is not able to take control? It will be ideal to see a log file

These are my missions:

    The issue is the unlocks aren’t carrying over anymore for some reason, so presumably the only solution is to implement the unlock API from their SDK.

    If I would get a new account, could be this issue be gone

    This issue is not related to your Dronelink account. It is an issue with the firmware on the drone not allowing virtual stick control because of the NFZ unlock not carrying over to third-party apps using the DJI SDK.

    You can call it a bug, and we can call it a feature request (the only solution is to implement the unlock API from their SDK), but the end result is the same: you can't do what you want and we need to write more code to make it happen.

    You need to make that mission public {copy to a public repository), the mode switch on the controller needs to be in normal

    Try to help if I can. Which IOS Device ? Looks like your using the current production version and it should work as I used it on 13 different missions between May 20th to June 13th without issues with my iPad 11 Pro. Is the DJI Fly app still running in background ? If so it needs to be force closed once it has fully loaded and the GEO Zone checked in the app to make sure it’s in there. If you did unlock the DJI Geo zone it is still possible it may not work as some have mentioned sometimes it works and sometimes it doesn’t. Seems to be no reason why. You said you can fly manually with both apps but were you able to start the motors and fly the drone manually at that same location ? If it is an issue with the unlocking of a the GEO Zone areas that is controlled by DJI and DL has no control over that. Also the Unlocks are only good for 3 days so make sure it is set up for the day you fly. 

    If the strong winds let up here later today I will try to fly it but I don’t see any issue with the plan. It’s a very small simple map mission so I doubt that would affect the operation. Some thoughts and suggestions.

    1. The drone is in or near a no fly zone which has not been unlocked - Zone unlocked

    Other users have reported that if you have multiple zones unlocked, only the last one carries over to DL.

    Hei Milke. Thanks for your comment.

    - Im running in an iphone SE 2020. No problems til last week.

    - The DJI app is not running in the background.

    - I can fly the drone in the same location in both apps.

    - I re tried today and no suceess. 

    Hei Jim.
    - I only have one licence that is for multiple zones, but have always work so I dont see why randomly now it may have stop working. The drone have not add any impact nor electrical discharge.

    My big question to the people behind the code: Could you please indicate in future versions why Dronelink is not able to take control? or at least a log file where I can read that? At the moment is quite annoying to be honest.

    Thanks!

    Update: I have reinstall my phone, reinstall all apps, create a simpler plan and got a new licence for a year in DJI. Still, Dronelink is unable to take control after elevating 5-6 metters

    Probably the only solution is for us to actually implement the unlocks directly in Dronelink:

    Mmm that is not my problem as I could fly in restricted areas before.

    my question. Do you know if the DJI SDK change before version 1.10.1 to 1.10.4 of DJI app? 

    I just tried with another iphone (same versions) and it didn't work, so is not my phone neither

    If I would get a new account, could be this issue be gone? Or a reset of my actual account/ actually I have log out of the app. That may help. I will try tomorrow

    Thanks Jim!

    Then we have a bug no?

    I would just like to mention that I’m in a restricted zone that is surround by an authorisation zone (red and blue in DJI fly safe respectively).
