Good day,

 

I'm getting "null" when requesting the drones serial number [serialNumber = s;]? Please advise. I'm using the DJI Mini SE and DJI Air 2S, with DJI MSDK 4.16 (Android).

 

Sample:

Mobile-SDK-Android/FlightHubView.java at e0a9b92611ff3a1deb2976fba8d6cafe4548488d · dji-sdk/Mobile-SDK-Android (github.com)

 

Aircraft aircraft = (Aircraft) DJISampleApplication.getProductInstance();
            if (null != aircraft.getFlightController()) {
                flightController = aircraft.getFlightController();
                flightController.getSerialNumber(new CommonCallbacks.CompletionCallbackWith<String>() {
                    @Override
                    public void onSuccess(String s) {
                        serialNumber = s;
                    }
                    @Override
                    public void onFailure(DJIError djiError) {
                        ToastUtils.setResultToToast("getSerialNumber failed: " + djiError.getDescription());
                    }
                });
            }

  Please try the latest 4.16.2 version. Are you able to see the serial number in DJI FLY app?

  That method appears to be asynchronous - the attribute "private String serialNumber;" doesn't get set since the data is not properly available, hence the 'null'. Is there an easier way to access the serialNumber value outside the asynchronous method's scope?

  There is no other way. I think this is the property of the serial number. Once the aircraft is connected with the MSDK, each component is connected afterwards, you have to asynchronously get the flightController object and its serial number.
