Your iPad or iPad mini is configured to use a wireless technology called Bluetooth, which enables you to make wireless connections to other Bluetooth-friendly devices. For your iPad or iPad mini, this includes Bluetooth headsets, keyboards, speakers, and printers.
In theory, connecting Bluetooth devices should be criminally easy: You turn on the Bluetooth feature on each device — in Bluetooth jargon, you make the device discoverable — bring them within 33 feet of each other, and they connect without further ado. In practice, however, there’s usually at least a bit of further ado (and sometimes plenty of it).
Clipping is a handy way to collect important slides you want to go back to later.
