"Android Wear iBeacon development"
summary
Explains how iBeacon over Bluetooth Low Energy works on Android 4.3+ (API 18) and how Android 5+ scan APIs add ScanFilter, ScanSettings and advertising so phones and Wear can act as transmitters on capable devices (Nexus 6/9). Shows beacon payload (manufacturer prefix, 16‑byte UUID, 2‑byte major, 2‑byte minor, 1‑byte tx power), background scanning patterns, permission and adapter setup, and the tradeoff between battery and detection latency (100 ms vs ~4.5 s). Notes practical uses (mall notifications, indoor navigation) and warns against using beacons for security-critical actions.
