Hands-Free Profile (HFP)
Overview
The Hands-Free Profile (HFP) defines how two devices that support HFP will
interact on a point-to-point basis. With HFP, a headset or any other Hands-
Free embedded unit can connect wirelessly to a cellular phone to act as the
cellular phone’s audio input and output mechanism. HFP applied in this way
also allows typical telephone functions to be performed without the need to
access the actual phone. The Hands-Free AG (Audio Gateway) role can be
used as the source side of the HFP connection. It can be used to connect
with a Hands-Free device, like a Bluetooth headset.
Two roles are defined for this application:
An
Audio Gateway (AG)
is a device that is the source of the audio, both for
input and output. Cellular phones are a typical AG role device.
A
Hands-Free (HF) unit
is a device acting as an Audio Gateway’s remote
audio input and output mechanism. Units in an HF role also provide some
remote control capabilities over AG devices.
Create a Headset connection
Establish a connection using one of these techniques:
•
Windows system tray, Bluetooth icon
•
From My Bluetooth Places
•
Using the Bluetooth Setup Wizard
NOTE: Most Bluetooth headsets “ring” when a connection is
attempted; answer the ring to complete the connection and begin using
the headest as the audio input/output device for this computer.
Close a Headset connection
•
If the connection was established via the Bluetooth icon in
the Windows system tray; click the Bluetooth icon, select
Quick Connect, Headset and then select the device that is
providing the service (active connections have a checkmark
in front of them).
OR
•
No matter how the connection was created, in My Bluetooth
Places, right-click the service name and select Disconnect.
