Volume Control

The BluetoothA2DPSink class provides the possibility to set the volume by calling the set_volume 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() {
}
