How to Turn On Bluetooth in Windows 10 or 11 and Pair Devices

Bluetooth is a short-range wireless technology standard that is in many of our daily devices. It’s named after King Harald Bluetooth, who united the disparate Danish tribes into a single kingdom. Bluetooth is one standard for our keyboards, mice, headsets and microphones. Laptops and mobile devices often come with Bluetooth pre-installed, older machines and desktops will often need a USB dongle or PCIe card installed to take advantage of this useful technology.

So how can we connect our Bluetooth devices to a Windows PC? How can we manage them? And how can we quickly connect in Windows 11? We’ll answer those questions in this how to.

How to Turn on Bluetooth and Pair Devices

4. Turn on a Swift Pair compatible device and make it discoverable.

5. Move the device near the Windows 11 device.

6. Click on the Connect button in the notification to pair and connect.

7. Your Swift Pair device is now connected and can be managed just like any other Bluetooth device.

Managing Bluetooth Devices

In the Bluetooth and Other Devices dialog we can find devices grouped by their function. Mouse, Keyboard and Pen inputs, Audio and Other. As we have connected a Bluetooth headset, we can find it under Audio.

1. Select the appropriate device from its group. Here we click on our headset. By default we can see the device’s battery and connection status.

The Bluetooth Connection Process

How Bluetooth devices connect at a human level is incredibly simple. We have two devices that we wish to connect. We set them both as discoverable and they will find each other. From there we pair the devices so that they can work together, we can also trust the devices so that they automatically connect when we power up our computer. But under the hood, Bluetooth is doing a lot of work for us.

  • Inquiry: Two Bluetooth devices, strangers to each other. One will make an inquiry to try and discover the other. The sender will send the inquiry and the receiver will listen to the request and respond with basic information such as its address and possibly name.
  • Connecting: The two devices will form a connection using the address of one another, addresses that were gained during the enquiry. Here devices will often need to be paired in order to be used. Keyboard will require us to type in a code, mice / joypads / headsets should auto-connect.
  • Connection: Devices will mainly go into an active mode, where they transmit and receive data. Some devices may go into “sniff” mode, a power saving mode where they will listen for connections.There are also “Hold” and “Park” modes where devices can go to sleep, waiting for a connection.
