Some work was needed to configure linux to recognize the keyboard and mouse. Intel Compute Stick can use BT keyboards During POST and in BIOS: https://www.intel.com/content/www/us/en/support/articles/000017249/intel-nuc.html https://www.intel.com/content/www/us/en/support/articles/000016213/intel-nuc.html You do need USB keyboard and mouse to pair BT devices with the Stick. Recent "enterprise" level systems have pretty full network support in "BIOS" with "Wake on WAN" so updates can be force fed to cubicle farms. Since BTLE is used by some two-factor authentication schemes (e.g., for proximity to a portable device), I expect it is inevitable that some form of BT will appear on enterprise devices, probably a small BT/HID stack similar to what USB dongles provide so they can configure systems so USB is not available. -- George N.
