Shows how to control real Bluetooth Low Energy (BLE) devices from the browser using navigator.bluetooth.requestDevice to discover services and characteristics and read/write values (example: writing FF 00 FF to an RGB lamp to change color and reading battery level). Demonstrates reverse‑engineering an official mobile app to reproduce its BLE protocol, driving a small Bluetooth drone from a progressive web app, and using beacons that broadcast a beacon URL for proximity. Reviews BLE Low Energy limits (Bluetooth 4.0/4.1: range, speed, power) and current browser support and permission model.
