Description:

The issue is that I can successfully stream PPI values using the Polar SDK library with Verity Sense, but I'm having trouble with PPG streaming using mApi.startOhrStreaming().

The relevant code is provided below:

private void PPIStreaming(String sensorID) {
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
        mApi.startOhrPPIStreaming(sensorID)
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(
                        new io.reactivex.rxjava3.functions.Consumer<PolarOhrPPIData>() {
                            @Override
                            public void accept(PolarOhrPPIData ppiData) throws Exception {
                                for (PolarOhrPPIData.PolarOhrPPISample sample : ppiData.samples) {
                                    Log.d("SENSOR","value:"+sample.ppi);
                                }
                            }
                        },
                        new io.reactivex.rxjava3.functions.Consumer<Throwable>() {
                            @Override
                            public void accept(Throwable error) throws Exception {
                                Log.e("PPI", "PPI stream failed. Reason: " + error);
                            }
                        },
                        new io.reactivex.rxjava3.functions.Action() {
                            @Override
                            public void run() throws Exception {
                                Log.d("PPI", "PPI stream complete");
                            }
                        }
                );
    }
}

The questions are as follows:

1. How can PPG streaming be used in Java with Polar SDK?
2. How should I define PolarSensorSetting in Java for use with the Polar SDK in java? I'm having trouble understanding how to use mApi.startOhrStreaming() for PPG streaming. Do you have any insights or suggestions on what might be causing this issue?
