How Bluetooth works

Understand pairing, range, interference and common limitations.

1. Bluetooth creates a short-range radio link between compatible devices after pairing.
2. Walls, the human body, distance and crowded 2.4 GHz radio traffic can weaken the connection.
3. Different profiles carry audio, keyboard input, file data or other functions; not every device supports every profile.
4. For connection problems, remove the pairing, restart both devices and pair again at close range.

Follow the official instructions for your device or service. Back up important data before changing settings or attempting repairs.
