Bluetooth is a short-range wireless technology standard operating at 2.4 GHz. It enables data exchange between devices within 10-100 meters. Named after Harald "Bluetooth" Gormsson, a 10th-century Danish king who united warring factions. Modern Bluetooth 5.0+ offers speeds up to 2 Mbps, improved range, and reduced power consumption compared to earlier versions.
Bluetooth Classic is used for continuous data streaming — audio to headphones, file transfers, and keyboard/mouse connections. Bluetooth Low Energy (BLE) is optimized for devices that send small amounts of data periodically — fitness trackers, heart rate monitors, smart home sensors, and beacons. BLE can run for months or years on a coin cell battery. The Web Bluetooth API primarily works with BLE devices.
BLE devices expose data through GATT (Generic Attribute Profile). Data is organized into Services (logical groupings like "Battery Service" or "Heart Rate Service") containing Characteristics (individual data points like battery level or heart rate value). Each service and characteristic has a unique UUID. Standard UUIDs are defined by the Bluetooth SIG, while manufacturers can define custom UUIDs for proprietary data.
Web Bluetooth requires Chrome, Edge, or Opera on desktop/Android. It is NOT supported in Firefox or Safari. On iOS, no browser supports Web Bluetooth due to Apple's restrictions. A secure context (HTTPS or localhost) is also required.
Probably not through this web test. Web Bluetooth primarily supports BLE (Bluetooth Low Energy) devices, not Classic Bluetooth audio devices. Headphones and speakers use Bluetooth Classic's A2DP profile, which isn't accessible through the Web Bluetooth API.
Yes. The Web Bluetooth API requires explicit user interaction — you must physically choose a device from a browser-managed dialog. Websites cannot scan for devices silently. Each connection requires fresh user consent. The API has strict security restrictions to prevent unauthorized access.
