What Is Bluetooth?
Bluetooth
is a type of radio communication. Bluetooth
devices
can find
and communicate with each other without using any wires.
Bluetooth
devices
(such as Bluetooth Phone Modules and
speakerphones) communicate through a common link that the two
devices share.
A Bluetooth device can
seek
other Bluetooth devices and determine
which ones are open. An
open
device is one that is awaiting a link. A
Bluetooth device can then
link
—establish an active connection—to
the device and begin exchanging voice signals or other data with it.
