Bluetooth wireless technology enables wireless connections between electronic devices within a range of 10 metres (33 feet). A Bluetooth connection can be used to send pictures, video clips, text, business cards or calendar notes to other devices using Bluetooth technology, for example, computers.
Since devices using Bluetooth technology communicate using radio waves, your phone and the other devices do not need to be in direct line-of-sight. But the connection can be subject to interference from obstructions, such as walls, or other electronic devices.
Several Bluetooth connections can be active at the same time. For example, if your phone is connected to another phone, you can also transfer files to another compatible device at the same time.
