Method Detail

onDataReceivedImpl

protected void onDataReceivedImpl(byte[] fft,
                                  int layersCount,
                                  float[] dBmArray,
                                  float[] ampArray)

Description copied from class: DbmHandler

Implement your own data conversion.

Specified by:

onDataReceivedImpl in class DbmHandler<byte[]>

Parameters:

fft - any data

layersCount - layers count

dBmArray - array of normalized (in range [0..1]) dBm values that should be populated by you. Array size is equals to layersCount value.

ampArray - array of amplitude values that should be populated by you. Array size is equals to layersCount value.

This values affect the appearance of bubbles. If new amplitude value is greater than previous value and normalized dBm value is greater than 0.25, bubbles will appear on screen. In case if amplitude is less than previous value, exponential smoothing (Holt - Winters) used for smoothing amplitude values.
