Spinning the physical web with android and bluetooth 5
summary
Shows that Bluetooth beacons actually broadcast tiny packets with Eddystone URL frame and telemetry fields, includes working Android code using Bluetooth LE scanner and advertiser APIs, and explains distance estimation via path loss (RSSI vs calibrated txPower) with numbers and caveats. Demonstrations include BBC micro:bits acting as beacons (dinosaur demo that operates live) and a phone advertising as a beacon. Claims Bluetooth 5 gives ~4× range and higher throughput and cites ABI Research’s ~500M beacons/year forecast.
