How to Check Bluetooth Versions on Windows 11

This guide explains how to find the Bluetooth version on your Windows 11 computer.

In our previous post, we showed you how to turn on or off Bluetooth, pair Bluetooth devices with Windows 11, fix common Bluetooth issues, and more.

Bluetooth is a wireless tool that links your computer to devices like headphones, mice, and keyboards. Many devices require a specific Bluetooth version to work correctly. Knowing your version helps you troubleshoot connection problems.

Why check your Bluetooth version?

You should check your version if your device is acting up or not connecting. It helps you see if your hardware is outdated or if you need to look for firmware updates.

What happens when done?

Once finished, you will have a specific LMP number. You can compare this number to our chart below to see exactly which Bluetooth standard your computer uses.
