DasBluetooth, a Submarine Radar for Nearby Bluetooth

Field notes

The interface models Bluetooth Low Energy activity as a submarine console, exposing heading, depth, contacts, ripples, signal thresholds, packet counts, and a device log. It offers a fake-device demo alongside movement alerts, screen wake, and audio controls. The page states that it runs client-side and does not exfiltrate data, while also acknowledging that Chrome’s private radio cannot be opened by the site and that live scanning is not currently available.
