On Windows 10, Bluetooth is a short-range networking technology that allows you to connect compatible devices (such as headphones, speakers, mice, and keyboard) to your computer wirelessly.
Although for the most part, you never need to worry about the version of the Bluetooth adapter you’re using. Sometimes in order to use a specific feature, you must have a particular version that includes a specific technology. For example, starting with Windows 10 version 1803 (April 2018 Update), your device must have a Bluetooth 4.0 with Low Energy (LE) support if you want to use Nearby sharing feature to send files and links to nearby devices.
If you need to know the adapter version on your computer, you can quickly find out checking the company’s support website, or just checking your system information.
How to tell the Bluetooth adapter version number on Windows 10
You can use these steps to find out the adapter version number of your Bluetooth:
Search for Device Manager and click the top result.
Expand the Bluetooth category.
Right-click the Bluetooth adapter, and select Properties.
Click on the Advanced tab.
Under “Firmware,” make a note of the LMP version number.
After completing the steps, check the LMP number using the list below to find out the actual Bluetooth version:
|3||Bluetooth 2.0 + EDR|
|4||Bluetooth 2.1 + EDR|
|5||Bluetooth 3.0 + HS|
If you find out that your computer doesn’t have a version with the required feature you need, you can always get an inexpensive USB Bluetooth adapter from Amazon.
