  • Staff

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.




Here's How:

1 Open Device Manager (devmgmt.msc).

2 Expand open Bluetooth. (see screenshot below step 3)

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.

4 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)

5 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.

Link Manager Protocol Version (LMP)​
LMP 0Bluetooth Core Specification 1.0b (withdrawn)
LMP 1Bluetooth Core Specification 1.1 (withdrawn)
LMP 2Bluetooth Core Specification 1.2 (withdrawn)
LMP 3Bluetooth Core Specification 2.0 + EDR (withdrawn)
LMP 4Bluetooth Core Specification 2.1 + EDR (deprecated, to be withdrawn)
LMP 5Bluetooth Core Specification 3.0 + HS (deprecated, to be withdrawn)
LMP 6Bluetooth Core Specification 4.0
LMP 7Bluetooth Core Specification 4.1
LMP 8Bluetooth Core Specification 4.2
LMP 9Bluetooth Core Specification 5.0
LMP 10Bluetooth Core Specification 5.1
LMP 11Bluetooth Core Specification 5.2


That's it,
Shawn Brink

I turn it off or on from "Quick Settings" but sometimes it (the button) doesn't work (I don't know why)? It's good if I turn it on or off in "Settings" but has problem with "Quick Settings". Sometimes when I turn it off (in "Quick Settings") my another BT device recognizes it as an turned on BT and ready to transfer device.

Great. Bluetooth Core Specification 4.2. Now my system feels antiquated! I'll have to look into seeing if I can upgrade it somehow!

    Maybe I'll make room somewhere and connect to the Dev channel if possible.
