Bluetooth Wireless Technology
Bluetooth Profiles
The Bluetooth interface will first attempt to connect in Hands Free
mode to a cell phone, allowing 3.4 kHz telecom bandwidth. If this is
not available, it will attempt to connect in Wireless Headset mode to
any product, such as a laptop computer, that allows a Bluetooth
wireless audio connection. The Wireless Headset mode offers 20
kHz audio bandwidth.
BlueKeeper supports A2DP, Hands Free and Headset profiles with
BlueCore 5-Multimedia technology. In Headset mode, you will be
able to receive full bandwidth stereo audio from any cell phone that
supports A2DP.
While all phones and portables are different, typically if you connect
in cell phone Hands Free mode, you will have a mono full duplex
connection. If you connect to a music player, you will be in stereo
A2DP mode. Phone conversations have a limited bandwidth of 300-
3.4 kHz. Consult your cell phone or portable device for more de-
tails.
There are many profiles that may be used for Bluetooth communi-
cation. BlueKeeper is compatible with these three typically used in
cell phones and headsets:
A2DP (Advanced Audio Distribution Profile)
Headphone mode used for stereo music streaming.
30-20 kHz stereo, receive only, headphone mode
Headset
Facilitates mono, full-duplex audio between two
paired devices.
300-3.4 kHz mono, both directions
Hands-Free Similar to Headset profile but allows the receiving
device more control over the call such as volume,
accept/reject/end a call.
300-3.4 kHz mono, both directions
