Some information on BLUETOOTH ®
Bluetooth® is an industrial specification for wireless personal area networks
(WPAN).
It provides a standard, inexpensive and safe method to exchange information
between different devices through a safe short-radius radio frequency.
Bluetooth® looks for the devices within a radius of a few dozen metres and if
these devices are covered by the signal, it allows them to communicate with
one another. These devices can be palm-held devices, mobile phones, perso-
nal computers, laptop computers, printers or digital cameras.
Bluetooth® technology does not have infinite resources and therefore can
connect only a definite number of devices at the same time.The resources it
consumes depends on the technology of the peripheral. For example, an MP3
player uses all the available resources to offer the best sound quality and so
often connection to other devices is not possible.
Advanced Audio Distribution Profile (A2DP)
This profile defines how high quality audio (stereo or mono) can be streamed
from one device to another over a Bluetooth ® connection. For example, music
streamed from a mobile phone to a wireless headset.
Hands-Free Profile (HFP)
This is commonly used to allow car hands-free kits to communicate with mo-
bile phones in the car.Most bluetooth ® headsets implement both Hands-Free
Profile and Headset Profile, because of the extra features in HFP for use with a
mobile phone. For example: last number redial, call waiting, voice dialing.
Headset Profile (HSP)
This is the most commonly used profile, providing support for the popular
Bluetooth ® Headsets to be used with mobile phones. It relies on SCO for
minimal controls including the ability to ring, answer a call, hang up and
adjust the volume.
Intercom Profile (ICP)
This is often referred to as the walkie-talkie profile. It is another TCS (Telephone
Control protocol Specification) based profile, relying on SCO to carry the
audio. It is proposed to allow voice calls between two Bluetooth ® capable
handsets, over Bluetooth ®
