I am having the exact same issue as ShadowMars. I tried uninstalling the USB drivers, switching to a different USB port (2.0. 3.0, 3.1—I should note I am using the Vive Pro Kit), and uninstalling other Bluetooth devices (USB dongle), but none of these solved the problem. Trying to Enable Bluetooth Communication only makes the app display the error message every time (Bluetooth Service Error: BT-112). I noticed that this feature broke only recently, and I'm guessing it might be related to SteamVR update. I'd be looking forward to some insight from anyone more knowledgeable on the subject.
