Bluetooth allows you to connect external devices to your iPad that would otherwise not work with the pin connector at the bottom of the device, like keyboards, mice, and other peripherals. Since Bluetooth is disabled by default, this tutorial explains how to turn it on, or enable Bluetooth, on your iPad.
Follow these steps to enable Bluetooth and find devices to pair with your iPad:
Click on the "Home" button, and flick through Home screens until you find the "Settings" icon: then tap on it.If you decide that you want to turn off Bluetooth to save battery life, just follow the steps outlined above, and this time hit on the switch to turn it off; obviously, any external device that depends on Bluetooth to work with your iPad will no longer work until you manually re-enable Bluetooth.
