" summary

Claim: browsers can control real BLE hardware. Uses the Web Bluetooth API (navigator.bluetooth.requestDevice) with Chrome/Opera/Samsung support and relies on BLE not classic Bluetooth — Bluetooth Low Energy — which vendors ship at about 10 million devices per day. Built demos: heartbeat monitor, Bluetooth printer, Philips- and custom RGB bulbs, an LED matrix, Lego car and a drone; tools: Bluetooth sniffer and decompiled APKs to reverse custom UUIDs and checksums. Most demos work live here though congestion sometimes breaks them.
