How to check a Bluetooth device version in 🪟 Windows 11
To check your Bluetooth version Windows 11 computers use, open Device Manager from the Start menu and find your adapter properties. This built-in tool shows the exact LMP (Link Manager Protocol) version number under the Advanced tab, which tells you whether your hardware supports Bluetooth 4.0, 5.0, or a newer release.
Here’s how to check your Bluetooth device’s firmware version in Windows 11.
With Bluetooth enabled in Windows, open Device Manager.
Open the Start menu , type Device Manager into the search box, and select the matching result under Best match.
Once Device Manager opens, click on Bluetooth to expand that category.
With the Bluetooth category expanded, right-click on your Bluetooth device (for example, Intel(R) Wireless Bluetooth(R)) and choose Properties. This is shown below.
In the properties window that appears, select the Advanced tab. Look for the LMP (Link Manager Protocol, the underlying standard your hardware uses) entry inside the Firmware or Firmware version section.
This listing will display your Bluetooth device's firmware version.
Consult the chart below to help identify the version and its associated capabilities.
