# BLEFYI

> Comprehensive Bluetooth Low Energy reference for embedded engineers, IoT developers, and product designers. Covers BLE SoC chips, Bluetooth versions 4.0-6.0, GATT profiles and services, beacon protocols (iBeacon, Eddystone), mesh networking, manufacturers, use cases, interactive tools, glossary, and guides. 15 languages supported.

## Data Scope
- BLE SoC chips with full specs (processor, memory, GPIO, radio, power, security, multi-protocol)
- Bluetooth versions 4.0 through 6.0 with key features and spec documents
- GATT profiles and services with UUID, characteristics, and version requirements
- Beacon protocols: iBeacon, Eddystone, AltBeacon with advertising format details
- Bluetooth Mesh topology: node types, provisioning, relay, proxy, friend
- BLE chip manufacturers with SDK info and developer portals
- Use cases: wearables, smart home, industrial IoT, healthcare, asset tracking
- Interactive tools: chip selector, GATT browser, power estimator, range calculator, UUID generator, packet builder
- BLE technology timeline
- Glossary and in-depth guides
- Side-by-side chip and version comparisons

## URL Patterns
- Append `.md` to any URL for plain-text markdown format.
