You may refer to the following document to get this information:
We appreciate your comments and we are working to revise and update the information in the advisory.
We would like to mention that with Intel® PROSet/Wireless Software for Bluetooth® technology the version of the package you download will be the same as the driver version shown in Device Manager.
We encourage users to obtain the BT drivers from the OEM, and only use the generic version from Intel as a last resort.
I installed File name: WP-BT_17.1.1501.01_s64.zip
and Device Manager reports the driver version as 17.1.1501.512.
That's what I'm interested in.
Here is the equivalent link to Bluetooth software like the one you have for Wi-Fi software: Intel® PROSet/Wireless Software — Intel® PROSet/Wireless Software for Bluetooth® Technology
The "version" shown is the PROSet software package version, which differs slightly from the actual driver versions that show up in Device Manager. We can work on adding the more information regarding the driver version as well for each software package that we post on our support web pages to describe the wireless and Bluetooth software that we post to download center. Thanks for your feedback.
