Hello,

 

I can't read the information about the obstacles distances. This is my code:

PerceptionManager.getInstance().addObstacleDataListener(value -> {
    objectsAboveLiveData.postValue(value.getUpwardObstacleDistance());
    objectsBelowLiveData.postValue(value.getDownwardObstacleDistance());
    if (value.getHorizontalObstacleDistance().size() != 0) {
        objectsInfrontLiveData.postValue(value.getHorizontalObstacleDistance().get(0));
        objectsBehindLiveData.postValue(value.getHorizontalObstacleDistance().get(1));
    }
});

Do I need to enable a type of obstacles avoidance? I really just want to know how distant they are. I have tried with the motors, on, off, and while the aircraft was flying. The information I have is always 0.0 for the up and down sensors, and null for the front and back.

Drone: DJI Mini 3 Pro; Remote Control: DJI RC Pro; SDK: msdk v5.3.0

Thank you

  mini3pro currently MSDK5.3.0 does not support obtaining obstacle avoidance data, so the value you get is 0 or null

  Any news about it? Having the same problem.

  Really not good this hidden limitations in MDSK. I see in other topics that supposedly we don´t have this kind of limitation

  I see that DJI Fly can get avoidance data.

  A similar situation happened to me with a Mavic 3 Enterprise

  PerceptionManager.getInstance().getRadarManager().addObstacleDataListener(data ->
  Log.d(Const.TAG, "radarObstacleDataListener: " + data.toString()));

  The app gives me the following response in the logcat:

  radarObstacleDataListener: ObstacleData{horizontalObstacleDistance=[], upwardObstacleDistance=0, downwardObstacleDistance=0, horizontalAngleInterval=0}

  These values never change and the only time they are generated is when you start the application.

  Should these values change if I move my hand closer and further away from the sensors?
