    You are saying the camera command fails? Do you get an error message or can you post a screenshot / screen recording?

    I better explain what I want to realize.

    I want to take a video footage during a long flight pad.

    First I explain the complete manual approach no missions or flight plan.

    I set the camera Exposure mode to Shutter Priority, shutter speed 1/60, automatically the Aperture will be changed continuously during the complete footage to the best exposure.

    To freeze this setting I hit  the Data phone screen button “Exposure Lock”

    This exposure must be used for the complete video, this to avoid visual exposure level changes in the footage.

    To realize this via a mission:

    Unfortunately  “Camera Auto exposure Lock”  does not work, there are aperture changes during the complete footage.

    Thank you for your feedback

    It seems like you should issue the Camera Exposure Mode command before setting Camera Shutter Speed. Beyond that, when the Auto Exposure Lock command runs, I assume the mission keeps going without an error message? Is this on Android or iOS? Do you have access to the other platform to see if it is OS dependent?

    Problem is not solved.

    There are no error messages during the mission.

    OS is Android.

    If I hit the “Exposure lock” button on the Dronelink app on my data phone it toggles from highlighted to dark. Highlighted means ON.

    “Camera Auto exposure lock”  Enable, Enable means exactly the same as ON, please confirm.

    If I send a Mission Command “Camera Auto exposure lock” Enable is 100% will the AE button highlight?  important question.

    The problem of Video Footage with permanent exposure changes is not professional.

    How does Dronelink solve this problem?

    Do you have a user’s  manual?

    Do you have a video tutorial explaining  the usage of “Camera Auto exposure lock” commands

    Thank you in advance

    Yes, enabled means on.

    No user manual right now. The commands are just meant to be an automatic way to do the things that are possible manually through the UI. My first thought would be the command is actually succeeding, but the UI just isn't reflecting the change. The problem is you say that you continue to see the aperture change. One last thing to check would be to turn if off in DJI Go / Fly, run a mission that just performs this single command. Then go back to Go/Fly and see what the UI reports.

    Thank you Jim,

    Simple UI test.

    On the Data phone the Exposure Lock is not activated, the AE “lock”mini logo is not  highlighted.

    On the Datphone I activate manually the AE function, the AE “lock” logo is highlighted.

     

    On the Data phone the Exposure Lock is not activated, AE “lock” logo is not  highlighted.

    I execute a Mission Enable ”Camera Auto Exposure  Lock” on the data phone nothing changed

    My conclusion: the command Enable ”Camera Auto Exposure  Lock” is not working.

    To be sure can you do the same test on a Android Dataphone .

    Thank you in advance

    Not sure what you mean by Data phone. I meant to do the test between the UI in the DJI native app versus Dronelink before and after the command was issued. I can test it again myself, but it worked when we originally released the feature so it may be OS and Drone specific. Also, it will be a while before we will get around to testing it and at the moment no one else is reporting this issue.

    Data Phone = Mobile Device running the Android app

    The test is relative simple, you do not have to fly outdoor or start the motors I can do it in +- 2 minutes. If you follow my test description in the previous post.

    I never have had problems with DJI, Litchi and other programs since more as 2 years.

    The Dataphone is a “ONE plus version 6” it appears in the recommended list of Litchi.

    I will not go in details, but Using “Camera Auto Exposure lock” is really TOP, without makes it extra complex to handle, and compared to Litchi, Dronelink offers the best solution  .  .  .  if it works.

    I hope you change your mind.

    If someone ells is reading this, please help me I will really appreciate this.

    Best regards

    Francis

    We are committed to looking into it, I just can't give you a timeframe.

    I was able to reproduce and fix this issue. Will be available with the 1.7.2 release. Thanks for reporting it!
