Volume Control

The BluetoothA2DPSink provides the possibility to set the volume by calling the setVolume method. This is also used for adjusting the volume via AVRC.

We provide different implementations of the VolumeControl which have different properties:

You can select an alternative implementation the following way:

#include "BluetoothA2DPSin.h"

BluetoothA2DPSink32 a2dp_sink;
SimpleExponentialVolumeControl vc;

void setup() {
  a2dp_sink.set_volume_control(&vc);  
  a2dp_sink.start("BTExpVolume");  
}

void loop() {
}
