    This class was removed when DJI changed the SDK. See the Drone Mission example.

    Hello Erel!

    I run the app. In Samsung S7 Edge. The problem is the screen are inverse and can't rotate. All apps do is no android problem. Rotation is enable.
    But the djidemo (both) are inverted and is imposible to rotate (fixed)
    What can i do?

    Thanks

    The demo sets the orientation to the standard landscape orientation. You can change it with the #SupportedOrientations attribute.
    For further discussion please start a new thread.

    Why have you removed the "ReferenceOnly" attribute? Which version of B4A are you using?

    I've installed 7.8 version.
    For Erel, because don't compile with the parameter.

    Read now it's that it's required release 8. I update and try.
    thank

    You must add such information when you say that you are running the example. We cannot guess which changes you made to the example...

    Hi,
    after following all the steps successfully, I can not make the app connect with the drone.

    The DJI app connects.

    Can you tell me what I have to do to make it connect?

    thank you

    SUPER COOL! Question? Can you control the camera with this? Specifically I want to change the shutter speed and then capture an image programmatically. In essence, I want to create an true automatic exposure bracketing routine with more control than the built in disaster lacking any imagination.

    These kind of things will really inspire a programmer. Sure, I could make an app to fly the Drone but photography and cinematography is why we fly. creating a beautiful HDR (High dynamic range) photograph requires exposure bracketing. from what i read of DJI's version, they change the ISO to create the AEB. I want to not only change the shutter speed but change the number of exposures to infinity if I choose. So essentially:

    • Take and image at the current Shutter speed
    • Drop 1 f stop and take another image
    • drop 2 f stops and take and image
    • Drop 3 f stops and take an image
    • drop 4 f stops and take an image
    • return to original shutter speed
    • add 1 f stop take and image
    • add 2 f stops and take and image
    • add 3 f stops and take and image
    • add 4 f stops and take and image
    • alet me that it is finished.
