Gyro streaming 1hz

  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.

  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

  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:

  08-25 11:24:09.771 13615-13711/com.example.ram.rproaccelerometertest I/MetaWear: Connected

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