Bluetooth feature in RDKFeature Descriptions
Audio Output SourcesBluetooth audio may be different than HDMI audio (e.g. secondary audio program, application sourced audio such as Pandora, voice navigation audio, etc).
Audio Output RoutingDetail PCM audio routing to Bluetooth A2DP SRC, It uses H/W accelerations, S/W processing, RMF involvement on streaming audio/video contents.
Audio EncodingDetail SBC (sub-band coding) and aptX encoding (Bluetooth chip, in software, or in SoC hardware).
Audio Output MutingThe Bluetooth audio output may be muted independently of other audio outputs (e.g. HDMI)
Audio Input (Settop as AD2P SNK)Using RDK device speakers over bluetooth i.e transmitting audio input back to a speaker connected with RDK device.

Audio Output SourcesBluetooth audio may be different than HDMI audio (e.g. secondary audio program, application sourced audio such as Pandora, voice navigation audio, etc).
Dual DecodeSupports ability to simultaneously output one audio stream to HDMI and a different audio stream to Bluetooth
Power ControlIn future, the power state of each Bluetooth connected device and the Bluetooth subsystem can be controlled
Audio/Video Remote Control Profile (AVRCP)Controller (Remote Control) sends mute and volume commands to target. AV/C commands are defined by the 1394 trade association

Bluetooth Architecture

Bluetooth Manager and Bluetooth HAL [BTRCore] is that Bluetooth Manager implements the BT HAL [BTRCore] API.  Then BT HAL [BTRCore] integrates and manages the BlueZ stack though the D-BUS interface.
