bluetooth: The adapter now scans for Bluetooth Low Energy peripherals around it and reports what it finds to Device Manager, so devices are discovered at the site they are actually in rather than only near the node.
bluetooth: A discovered peripheral can be paired and then read from and written to through the adapter, including subscribing to updates it pushes. The adapter relays the full exchange, so a remote Bluetooth device behaves the same as a local one.
connectivity: A single link to the node now carries discovery and device traffic together, so adding Bluetooth did not add another connection to open or maintain.
