Bluetooth operation
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 headset and
communication 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 to use the 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 head-
phones.
AVRCP
Based on the GAP Profile, it uses a Controller (CT) - PDA, computer mobile phone etc., that
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, Remote Controller with LCD.
