Bluetooth is a wireless technology that enables your iPad to make wireless connections to other Bluetooth-enabled devices. When you bring the Bluetooth device to within 33 feet of your iPad (that’s the maximum Bluetooth range), they connect when the following criteria are met:

 Both devices are discoverable. Bluetooth devices only broadcast their availability to connect — that is, the devices make themselves discoverable — when you say so. So, nothing can happen until you make both your iPad and the Bluetooth device discoverable.

 You pair the iPad and the device. Just because both your iPad and your Bluetooth device are discoverable, it doesn’t follow that the connection is automatic. The connection happens only when you pair your iPad with the other device. In some cases, this pairing requires you to enter a multidigit passkey into the Bluetooth device (as long as the device has a keypad of some kind). Otherwise, you pair the devices by tapping a Pair button that your iPad displays.
