Install the Wireless-LAN feature from servermanager, and you should be able to install Wifi driver. As far as I know, Windows Server does not have Bluetooth stack built-in. It is impossible to use Bluetooth with Windows Server unmodified. There are patches which ports the Bluetooth stack from the non-Server version of Windows, but haven't tried myself.
The operating systems supported by this NUC are Windows® 7, 8.1 and 10. It will be necessary to use a generic Windows® driver.
