Bluetooth is a short range wireless technology which enables wireless data transmission between two Bluetooth enabled devices located nearby each other.
There are many different types of Bluetooth enabled devices you can add and pair to your PC, such as mobile phones, wireless headsets, speakers, fitness trackers, mouse, keyboard, etc...
Bluetooth accessories sometimes require a minimum Bluetooth specification (version) in order to work with full functionality.
This tutorial will show you how to see which Bluetooth version you have on your Windows 10 and Windows 11 PC.
It is required to turn on Bluetooth to see which version is it.
Open Device Manager (devmgmt.msc).
Expand open Bluetooth. (see screenshot below step 3)
Perform one of the following actions: (see screenshot below)
- Double click/tap on the Bluetooth radio device (ex: "Intel(R) Wireless Bluetooth(R)").
- Right click on the Bluetooth radio device (ex: "Intel(R) Wireless Bluetooth(R)"), and click/tap on Properties.
Click/tap on the Advanced tab, and look for the LMP (Link Manager Protocol) listing in the Firmware or Firmware version area. That number (ex: "10.256") tells you what LMP version (ex: "10") you have on your device. (see screenshot below)
Find your version number (ex: "10.256") on the table below to map your LMP version (ex: "10") to its Bluetooth Core Specification number (ex: "5.1"). That's the highest core specification your device fully supports. Accessories with higher specifications may still work, but with reduced functionality.
