## What it is
The W3C Web Bluetooth Community Group's repository hosting the Web Bluetooth specification, which defines JavaScript APIs for websites to securely communicate with Bluetooth Low Energy (BLE) devices. It includes the spec source, use cases, security requirements, implementation status, and links to samples and demos.

## Use cases
- connect to BLE heart rate monitors from a web page
- control Bluetooth toys or robots from the browser
- read sensor data from IoT devices in a web app
- check which browsers support the Web Bluetooth API
- learn how to pair Bluetooth devices securely on the web
- build a web-based BLE device flashing tool

## When to choose
- you are implementing the Web Bluetooth API in a browser
- you want the authoritative spec and security model for web Bluetooth access
- you need reference material, samples, or implementation status for BLE web apps

## When to avoid
- you need a Bluetooth stack or driver for a native app
- you need Bluetooth Classic (non-BLE) support
- you need a JavaScript polyfill or runtime library rather than a specification
- your target browsers do not implement the API

## Facets
- artifact type: learning-resource
- maturity: active
- function: sdk, security, documentation
- domain: web-development, iot, apis, hardware
- platform: browser
- tags: web-bluetooth, bluetooth, ble, w3c, specification, web-api, gatt, web-server
