5.5 Bluetooth Dongles Notes

Bluetooth technology is a wireless technology that allows devices like computers, cell phones,
headsets and PDAs to communicate with each other. This communication facilitates data transfers
quite easily, and has heralded a new age in wireless computer and cell phone accessories. If you
have a computer and you want to use Bluetooth accessories with it (such as a printer, keyboard,
headset or mouse) then you will first need a Bluetooth adapter.

5.5.1 Use

The function of a Bluetooth adapter is to allow you to create a Bluetooth network for your computer
if it is not already Bluetooth-enabled. Once this network has been created, your computer will be
compatible with all Bluetooth-enabled wireless devices. Other uses of a Bluetooth dongle include:

z z Listening to Music: Bluetooth can be used to stream audio to headphones or even speakers.
These speakers or headphones will typically be battery-powered. By using such devices,
you can play music on your computer and listen in from another room.

z z Transferring Files: A Bluetooth connection between computers can be used to stream files.
By pairing two computers together, a shared folder can be established, allowing multiple
users access to a database. This makes it convenient to work on files that are frequently
updated.
z z Customizing your Phone: Unless your phone has had its usability crippled by your carrier,
you can send ringtones and wallpapers to your phone. This gives you the option to take
your own collection of pictures and music, and transfer them to your phone using the
software that is included and activated with your dongle.

z z Streaming Media: If you have the proper hardware, such as a TV that can interface with
a laptop or a Bluetooth-enabled TV receiver, you can activate a connection between your
main computer, with a dongle installed, and your TV or laptop. You can use this connection
to stream movies or pictures to your TV from your now Bluetooth-enabled computer.
z z Controlling Mechanical Devices: If you’re tech-savvy, it is possible to take advantage of
a Bluetooth reciever to engage physical switches. With the proper set-up, you can use a
Bluetooth dongle on your home computer to activate lights, sprinklers, cameras or other
such devices within a range of about 100 meters. Such a set up may require some technical
know-how and a good bit of solder.
