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.
