What is Bluetooth visibility?

Bluetooth visibility refers to whether other devices can discover your computer when searching for Bluetooth devices. When Bluetooth is turned on and the Bluetooth panel is open, your computer will advertize itself to all other devices within range, allowing them to attempt to connect to your computer.

You can change the name your computer displays to other devices.

After you have connected to a device, neither your computer nor the device needs to be visible to communicate with each other.
