Your iPad and Bluetooth Devices
On the iPad, you can use Bluetooth to communicate wirelessly with a compatible Bluetooth headset or to use an optional wireless keyboard. Such accessories are made by Apple and many others.
To ensure that the iPad works with a device, it has to be wirelessly paired, or coupled, with the chosen device. If you’re using a third-party accessory, follow the instructions that came with that headset or keyboard so that it becomes discoverable, or ready to be paired with your iPad. Then turn on Bluetooth (on the Settings screen) so that the iPad can find such nearby devices and the device can find the iPad.
In the figure, an Apple Wireless Keyboard and the iPad are successfully paired when you enter a designated passkey on the keyboard. You won’t need a passkey to pair every kind of device, though. You can’t, for example, enter a passkey when pairing the iPad with a wireless speaker. Bluetooth works up to a range of about 30 feet.
You know Bluetooth is turned on when you see the Bluetooth icon on the status bar. If the symbol is white, the iPad is communicating wirelessly with a connected device. If it’s gray, Bluetooth is turned on in the iPad, but a paired device isn’t nearby or isn’t turned on. If you don’t see a Bluetooth icon, the setting is turned off.
To unpair a device, select it from the device list and tap Forget this Device.
The iPad supports stereo Bluetooth headphones, so you can now stream stereo audio from the iPad to those devices.
The iPad can tap into Bluetooth in other ways. One is through peer-to-peer connectivity, so you can engage in multiplayer games with other nearby iPad, iPhone, or iPod touch users. You can also do such things as exchange business cards, share pictures, and send short notes. In addition, you don’t even have to pair the devices as you do with a headset or wireless keyboard.
You can’t use Bluetooth to exchange files or sync between an iPad and a computer. Nor can you use it to print stuff from the iPad on a Bluetooth printer (although the AirPrint feature handles that chore in some instances). That’s because the iPad doesn’t support any of the Bluetooth profiles (or specifications) required to allow such wireless stunts to take place.
