A2DP Audio over PCM

Question: Does the Sterling-LWB support A2DP audio CODEC over PCM output? Answer: Response below. A2DP defines the protocol and procedures to deliver "high-quality" mono or stereo audio from a Source (e.g. phone or computer) to a Receiver (e.g. headphones or stereo) over ACL channels. A2DP is supported via HCI.   ACL uses L2CAP at the Link Layer shown on Page 11 (and 16) of the attached A2DP spec.   In contrast, "Bluetooth's (narrow band voice) Audio" uses SCO channels.  SCO data is streamed instead of framed, so no distinction exists between SCO logical transports and logical links:  SCO operates over PCM or HCI (CPU intensive).   There is no support for A2DP over PCM.   More on ACL/SCO is found in Section 1.1.X at  https://en.wikipedia.org/wiki/List_of_Bluetooth_protocols#Asynchronous_…
