Bluetooth profiles

[Andreas]

People with BT profiles tend to find all kinds of accessories and believe them to ve compatible with their player. Unfortunately, there's a bunch of BT profiles and they aren't cross compatible, so the manufacturers have to include them for them to work. The most common are:

A2DP (Avanced Audio Distribution Profile):
Basically means stereo audio over BT, used with BT headphones and such.

AVCRP (Audio/Video Remote Control Profile):
This allows for headsets with controls to control the player, as the profile name says.
