Building a mobile location aware system with beacons
summary
Prototype builds a room-scale locator using off-the-shelf BLE beacons, an Android phone and the Estimote cloud to set proximity UUIDs; distance bands are immediate (2–3 ft), near (3–10 m) and far (up to ~70 m), BLE latency ~3 ms and battery life ~1.5 years. The demo uses the Estimote SDK, reads proximity identifiers, compares current vs previous distance to give cold/warm/hot feedback, handles emulator limits with a BLE USB adapter (Chris Larson library), and the game works.
