All about Bluetooth
YOU PROBABLY KNOW Bluetooth® best for cool, futuristic-looking devices
that some people use to talk hands-free on their cell phones. But there are
more than a billion Bluetooth-enabled devices in the world today, and they
extend well beyond the realm of mobile phones.
Bluetooth Wireless Technology allows different compatible electronic
products, such as your laptop and your PDA, to communicate wirelessly over
short distances. As a result, Bluetooth is popping up all over the place—in
cars, homes, businesses and even hospitals.
In short, Bluetooth means the various computers, wireless phones,
entertainment systems and accessories in your life are becoming more
convenient—and less messy—to use. You can now quickly send files to a
printer, easily connect a keyboard to your computer, play music through
your stereo from across the room, show favorite pictures from your laptop
on a TV or play video games enthusiastically, all without the disorder and
restrictions of wires.

How do you get connected?
Connecting two compatible Bluetooth-enabled devices is called pairing.
It’s generally a simple process that involves little setup. For detailed instructions, check the manual specific to each device. Many Bluetooth-enabled
devices are completely universal, so your devices can communicate with
others regardless of the manufacturer.
The only restriction is that devices must have the same profile in order
to communicate. There’s a profile for each type of function, and many profiles
can exist on a single device. A hands-free profile (HFP) would be found in
mobile phones and headsets; the Advanced Audio Distribution Profile (aka
A2DP) allows you to play music from your mobile phone through your stereo
or computer speakers. If you have a question about the profiles for a specific
device, it’s best to refer to its manual. A
