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.
