Gyro streaming 1hz

Malar

I can stream gyro data 25hz per second,Is there any way I can stream gyro data 1hz per second.
My second question is if I set my output rate 25hz per seconds, is there any way I can average each axis(x,y,z) data, and bring it to 1hz per second for streaming.

Eric

Use a timer filter with a 1000ms period.  

You can compute the average but you will have to compute it over each axis individually.  Furthermore, the average is a running average so you must periodically reset the average.

Thanks Eric, if possible could you please provide sample coding for timer filter with gyro stream.

See the documentation.

Thanks Eric. I tried but no results. Could you please check .

try {
    gyroModule = mwBoard.getModule(Bmi160Gyro.class);
} catch (UnsupportedModuleException e) {
    e.printStackTrace();
}

gyroModule.configure()
        .setOutputDataRate(OutputDataRate.ODR_25_HZ)
        .setFullScaleRange(FullScaleRange.FSR_500)
        .commit();
AsyncOperation<RouteManager> routeManagerResultGyro = gyroModule.routeData().fromAxes()
        .process(new Time(Time.OutputMode.ABSOLUTE,1000))
        .stream(GYRO_STREAM_KEY)
        .commit();
routeManagerResultGyro.onComplete(new AsyncOperation.CompletionHandler<RouteManager>() {
    @Override
    public void success(RouteManager result) {
        result.subscribe(GYRO_STREAM_KEY, new RouteManager.MessageHandler() {
            @Override
            public void process(Message msg) {
                final CartesianFloat spinData = msg.getData(CartesianFloat.class);
                Log.i(TAG, String.format("Gyroscope: %s", spinData.toString()));


            }
        });
    }
});

gyroModule.start();

At a glance, the code looks fine so try overriding the failure function to see if anything is returned there

Malar

I have tried with failure function still, running perfectly but no error or no result.

    @Override
    public void failure(Throwable error) {
        Log.i("Failure", error.getMessage());
    }
});

Result:

The only thing I can think of is to move the start function into the CompletionHandler, otherwise the code works fine for me.
