IoT: from zero to hero for web developers
summary
Shows how cheap BLE beacons (Eddystone) broadcast a URL that opens a web page which then uses Web Bluetooth in Chrome to read/write BLE characteristics and control an RGB LED — demoed end-to-end from beacon to browser control. Uses ARM mbed toolchain, Nordic nRF51/nRF52 boards and a JavaScript VM (JerryScript) that runs on ~64KB RAM (JS ~70x slower than C++ but sleeps aggressively), micro:bit accelerometer juggling demo, beacon battery claims (≈7 years @1Hz) and mbed usage stats (≈1.3M compiles/month).
