On Windows 11 (and on Windows 10), Bluetooth is a short-range networking technology that allows you to connect compatible devices (such as headphones, speakers, mice, and keyboards) to your computer wirelessly.
Although, for the most part, you never have to worry about the version of the Bluetooth adapter you use. Sometimes, to use a specific feature, you must have a particular version that includes a specific technology. For instance, your computer must have Bluetooth 4.0 with Low Energy (LE) support if you want to use the Nearby sharing feature to send files and links to nearby devices.
If you need to know the wireless adapter version, you can quickly find out by checking the company’s support website or the system information.
Check Bluetooth version on Windows 11 (and 10)
To check the Bluetooth version on Windows 11 or Windows 10, use these steps:
Search for Device Manager and click the top result to open the app.
Expand the Bluetooth category.
Right-click the Bluetooth adapter and select the Properties option.
Click the Advanced tab.
Under the “Bluetooth Radio Information” section, check the “Firmware Version” field and note the LMP (Link Manager Protocol) version number.
- Check the LMP version using the table below to determine the Bluetooth version on Windows 10.
In this case, the LMP has the #4, so the version is “Bluetooth 2.1 + EDR.” Here’s a table with the available Link Manager Protocol versions, which you can use to confirm the actual Bluetooth version:
|3||Bluetooth 2.0 + EDR|
|4||Bluetooth 2.1 + EDR|
|5||Bluetooth 3.0 + HS|
Once you complete the steps, you will know the adapter version you have on your computer. If you find out that your device doesn’t have a specific version with a required feature, you can always get an inexpensive USB Bluetooth adapter from Amazon.
