I looked into this a few years ago for a personal project. One reason why BeaconDB only uses WiFi APs for geolocation, is because they are usually stationary (excluding mobile hotspots) and so their location, once identified, can be used as a reference point for triangulation. But the BLE beacons are by design small, portable and usually attached to a moving object. Since BeaconDB doesn't know whether a specific beacon is meant to be stationary or moving, its not safe to use it as a reference point for geolocation.
