Bluetooth Profiles
In order to use Bluetooth technology, devices must be able to interpret certain profiles.
This unit is compatible with following profiles.
GAP (Generic Access Profile)
HSP (Hands Set Profile)
HFP (Hands Free Profile)
GAVDP (Generic Audio/Video Distribution Profile)
A2DP (Advanced Audio Distribution Profile)
AVDTP (Audio/Video Distribution Transport Profile)
AVRCP (Audio/Video Distribution Remote Control Profile)
GAP
GAP is short for Generic Access Profile. This is a basic profile of Bluetooth wireless
technology.
HFP
HFP is short for Hands-Free Profile. This profile is used for hands-free phoning with the
devices featuring Bluetooth wireless technology.
HSP
HSP is short for Head Set Profile. This profile is used for connecting a headset and
for communicating terminal wireless technology.
GAVDP
This profile uses an Initiator (INT), a device (such as a portable player) that initiates a
signalling procedure to send a request to an Acceptor (ACP), - such as headphones etc.
Although this profile specifies signalling transaction procedures between two devices to set
up, terminate and reconfigure streaming channels, using GAVDP alone, it is required to use
GAVDP in combination with profiles that depend on this profile - the AVRCP and the VDP.
A2DP
Mobile phones and devices with A2DP high quality stereo bluetooth profile.
This profile is based on the GAVDP, and allows advanced audio to be transmitted (audio
streaming) from a Source (SRK) - such as a CD player, to a Sink (SNK), such as
headphones.
AVRCP
Based on the GAP Profile, this uses a Controller (CT) - PDA, computer mobile phone etc.,
which sends a command to a Target (TG) - TV, discman, headphone etc. The command can
be to Play, record, colour control, volume control etc., depending on the nature of the devices
involved and the scenario. The commands are transported by a new additional protocol,
called the Audio/Video Control Transport Protocol (AVCTP). Some scenarios defined are
Remote Control from a Separate Controller, Remote Control and Audio Stream Between Two
Devices, and Remote Controller with LCD.
