Since devices with Bluetooth wireless technology communicate using radio waves, they do not need to be in direct line-of-sight. Bluetooth devices must, however, be within 10 metres (33 feet) of each other, although the connection may be subject to interference from obstructions such as walls or from other electronic devices.
Paired devices can connect to your tablet when Bluetooth is switched on. Other devices can detect your tablet only if the Bluetooth settings view is open.
Do not pair with or accept connection requests from unknown devices. This helps to protect your tablet from harmful content.
If you want to share your photos or other content with a friend, send them to your friend's device using Bluetooth.
You can use more than one Bluetooth connection at a time. For example, while using a Bluetooth headset, you can still send things to another device.
The passcode is only used when you connect to something for the first time.
If you no longer have the device with which you paired your tablet, you can remove the pairing.
