What is Bluetooth and how does it work?

Bluetooth is a way for your devices to talk to each other wirelessly over a short distance. Like headphones connecting to your phone, or a keyboard connecting to your computer. Once you pair them the first time, they remember each other and connect automatically.

Bluetooth is a wireless technology that lets devices communicate without cables. It works by sending radio signals between devices that are close to each other. About 30 feet. Once you pair two devices for the first time, they remember each other and connect automatically when you turn Bluetooth on. Bluetooth is designed for short-distance, low-power communication, which is why it works well for headphones, speakers, watches, and fitness trackers.
