No, HFP (Hands Free Protocol) is just intended for speech and is limited to 8KHz. Then A2DP
(Advanced Audio Distributiion Protocol) is intended for audio and is
able to transport audio with high sound quality (up to 48KHz sample
rates).
So far, I did not found a way to influence this from the
SDK or any other BlueSoleil tools (see also the thread about this issue
that I will post after this one); agreement about the A2DP parameters,
like CODEC, Sample rate, and sub bands is handled by lower levels of the stack.
