You can generally tell what devices will work with each other by looking at them logically. You wouldn’t be able to pair a mouse with a camera, since the camera isn’t designed to be controlled by the mouse. On the other hand, it would make sense to connect a headset to a mobile phone, since they are designed to work together.

Connecting a hands-free headset to a mobile phone. Connecting wireless mice, keyboards, and printers to laptops and other computers. Connecting portable media players and smartphones to speakers and car stereos. Wirelessly connecting video game controllers to computers and game consoles.

For example, if you wanted to connect a headset to your smartphone, you would put the headset into the discovery mode (refer to the documentation), and then search for discoverable devices on your smartphone.

When connecting a Bluetooth device to a computer, you may need to install the drivers for the device. This is usually done automatically, though the device may have come with a driver installation disc. You can also download drivers from the manufacturer’s website. There is no general “Bluetooth driver”, only drivers for specific devices. If you want to connect a Bluetooth device to a desktop PC, chances are the desktop PC does not have Bluetooth functionality. You will need to purchase and install a Bluetooth USB dongle in order to connect devices to the PC. Most laptops and virtually all Macs have Bluetooth support built-in. [1] X Research source
