What is Bluetooth?

Bluetooth is a short-range wireless technology used to connect computers, mobile phones, keyboards, stereo, and other electronic equipment. When two Bluetooth enabled devices are connected to each other, this is called pairing. For security purposes, it is usually required to enter or verify an access code during the pairing process. Devices can usually be connected up to 10 meters (32 feet) away.

Typical Bluetooth Devices

If you have an iPhone or iPad, there are several basic types of Bluetooth devices that work with your equipment.

Many types of audio and visual equipment such as dock stations, stereo, portable speakers, and TV’s.

Car kits that can provide both hands-free calling and listen music to car stereo systems via Bluetooth connectivity.

Since Bluetooth is a short-range network, the connection will be lost if you move the iPhone too far from the device, which for most accessories is about 32 feet (10 meters). Once the connection is lost, most devices will automatically reconnect when they are within range of the iPhone. If you disconnect the device, it must be connected again before it connects to your iPhone.
