The bt_speaker_agent is a node for communicating with the BlueZ bluetooth stack on Linux. It publishes information about connected Bluetooth audio sources, sends commands to those sources, and controls pairing.
When pairing is initiated by sending the appropriate command, Kuri will become visible as a Bluetooth audio device. It does not require any PIN code or password to pair. Only one connected device at a time is supported.
