BLUETOOTH


Bluetooth is a short-range wireless communications technology that replaces the cables connecting electronic devices. It uses the principle of device “inquiry” and “inquiry scan.” Scanning devices listen in on known radio frequencies for devices that are actively inquiring. When the scanner receives an enquiry, it sends a response with the information needed to forge a connection. It’s used for talking hands-free on a cell phone or listening to music or wireless headphones.
