- 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
