Getting RC model - MSDK 4

Hi, I am trying to get the model of the current connected RC.

Using MSDK 4 latest version, I am getting the DISPLAY_NAME key value, and comparing it to the ENUMs that start with the keyword DisplayName in RemoteController class (ex. "DisplayNameDJIAir2s").

The problem is, some RC do not support getting the DISPLAY_NAME, I am getting NULL value when getting that key, so I can't identify the connected RC model.

My code for getting the DISPLAY_NAME of RemoteController:

KeyManager.getInstance().addListener(RemoteControllerKey.create(RemoteControllerKey.DISPLAY_NAME), (o, o1) -> {
                String name = (String) o1;
                Logger.i(TAG, String.format("DISPLAY_NAME name: %s", o1));
                model = SupportedRemoteControllerModel.fromName(name);
            });

What am I doing wrong? Is there any other way to get the DISPLAY_NAME or maybe getting the Model of the connected RC?

  Which RCs are unable to use RemoteControllerKey.DISPLAY_NAME?

  Using the following method, you can obtain the name of the remote control. KeyManager.getInstance().getValue(RemoteControllerKey.create(RemoteControllerKey.DISPLAY_NAME), new GetCallback() { @Override public void onSuccess(@NonNull Object o) { String name = (String) o; Log.d("RemoteController", "DISPLAY_NAME: "+name); } @Override public void onFailure(@NonNull DJIError djiError) { Log.d("RemoteController", "onFailure: "+djiError.getDescription()); }});

  As I mentioned in the original post, I am getting NULL value with some controllers:

  "The problem is, some RC do not support getting the DISPLAY_NAME, I am getting NULL value when getting that key, so I can't identify the connected RC model."

  I understand your issue. After you change `addListener` to `getValue`, you will be able to retrieve the name of the remote control correctly. It has been tested and performs well on RM500 and other remote controls.

  I get NULL value when using getValue.

  When using addListener, I get nothing at all, the callback is not called.

  This is different from the results of my test. I was able to get the name through getValue on both the DJI Smart Controller and DJI Smart Enterprise Controller.

  Works for you and also works on other controllers we have.

  But on that specific Smart controller we get null value.

  Must be a faulty device, I will try reset to factory settings. Thank you!

  If the issue persists, perhaps you could record a video for us to visually assess the situation.
