Recently in the process of debugging a bluetooth chip, encounter a problem is not very understand, I connected the two bluetooth headset, one of which is a walk A2DP transfer protocol, audio transmission format for SBC; Another walk SCO transfer protocol, audio transmission format for the ACC,
I searched the Internet and A2DP protocol transmission quality is better, but use the ACC format transfer audio sound will be better, so I feel strange, why the bluetooth headset at the time of production, why not at the same time support A2DP and ACC? Is that for the sake of what? Have a great spirit and clear?
