Creating Bluetooth Low Energy Apps
summary
Live demos use Apache Cordova with a custom BLE plugin to scan, connect, read and write a real light bulb service (UUID FF10) and its switch characteristic (FF11), with about a hundred lines of JavaScript that actually toggle the bulb. Code handles ArrayBuffer/Uint8 parsing, supports write vs writeWithoutResponse and startNotification for heart rate streams. Also shows TI SensorTag buttons, Estimote iBeacons and iBeacon ranging, URI Beacon/Physical Web examples and Node.js libraries (noble/bleno) — all working end to end.
