OcuSync Link setChannelNumber on Mobile SDK Version 4.12 is not working

[paddy0489]

OcuSyncLink Set Channel Number is not working and receives e.g "OcuSync set channel number: 2455 error: Param Illegal".

Mobile SDK Version 4.12

Tested Drones:

• Mavic 2 Zoom : :x:
• Phantom 4pro v2.0 :x:
• Phantom 4 Standard (Lightbridge) :heavy_check_mark:
• Mavic Pro :heavy_check_mark:

Pre Configuration:

• Set Channel Bandwidth bandWidth to Bandwidth10MHz or Bandwidth20MHz.
• Set Frequency Band frequencyBand to FREQUENCY_BAND_2_DOT_4_GHZ or FREQUENCY_BAND_5_DOT_8_GHZ.
• Set Channel Selection Mode to ChannelSelectionMode.MANUAL.

Action:

• on 2.4Ghz Band: set channel between 2401 and 2477
• on 5.8Ghz Band: set channel between 5725 and 5849

Result:

• e.g "OcuSync set channel number: 2455 error: Param Illegal".

...
mOcuSyncLink.setChannelBandwidth(bandWidth, new CompletionCallback() {

    @Override public void onResult(DJIError djiError) {
        if (djiError != null) {
            Log.e(DEBUG_TAG, "set Channel Bandwidth: " + bandWidth.name() + " error: " + djiError.getDescription());
        } else {
            Log.d(DEBUG_TAG, "set Channel Bandwidth: " + bandWidth.name() + " accept");
        }
    }
});
...
...
mOcuSyncLink.setFrequencyBand(frequencyBand ,new CommonCallbacks.CompletionCallback() {
    @Override
    public void onResult(DJIError djiError) {
        if (djiError != null) {
            Log.e(DEBUG_TAG, "set frequency band " + djiError.getDescription());
         } else {
            Log.d(DEBUG_TAG, "set frequency band " + frequencyBand.name() + " accept");
        }
    }
});
...
...
mOcuSyncLink.setChannelSelectionMode(ChannelSelectionMode.MANUAL, new CommonCallbacks.CompletionCallback() {
    @Override
    public void onResult(DJIError djiError) {
        if (djiError != null) {
            Log.e(DEBUG_TAG,"channel selection mode set manual error: " + djiError.getDescription());
            }
        }
});
...

...
mOcuSyncLink.setChannelNumber(channel, new CommonCallbacks.CompletionCallback() {
    @Override
    public void onResult(DJIError djiError) {
        if (djiError != null) {
            Log.e(DEBUG_TAG,"OcuSync set channel number: "+ channel +" error: "+  djiError.getDescription());
        } else {
            Log.d(DEBUG_TAG,"OcuSync Channel accept: " + channel);
        }
    }
});

Dear Customer,

Thank you for contacting DJI. Have you checked the getChannelNumberValidRange before setting it?

Thanks,

Luce Luo DJI Dev Team

[paddy0489]

The Array integers contains [-1,-1] Why does this interface receives -1 ?

mOcuSyncLink.getChannelNumberValidRange(new CommonCallbacks.CompletionCallbackWith<Integer[]>() {
@Override
        public void onSuccess(Integer[] integers) {

        }
 @Override
        public void onFailure(DJIError djiError) {
           
        }
});
