Introduction
SemBeacon is a demonstrator application that scans for semantic Bluetooth Low Energy (BLE) beacons and visualizes the linked data they advertise on a map, making it easier to explore location-aware semantic data in the field. Developers, researchers and IoT enthusiasts may want SemBeacon to inspect SemBeacon-compliant broadcasts, simulate beacon behavior, and test integrations with personal data accounts. The app combines a multi-format scanner, a flexible beacon simulator with example scenarios, and a mechanism to broadcast a user WebID from a personal data provider, so you can both consume and emit linked data for experiments and demonstrations.
Key Features
⭐ Multi-format scanner: detects SemBeacon, AltBeacon, iBeacon, Eddystone-URL, Eddystone-UID and Eddystone-TLM broadcasts.
⭐ Automatic SemBeacon retrieval: fetches semantic linked data advertised by beacons and prepares it for visualization.
⭐ Map visualization: plots discovered beacon data on a map to explore spatial context and metadata.
⭐ Beacon simulator: simulate one or more beacons of types such as AltBeacon, iBeacon, SemBeacon and Eddystone for testing.
⭐ Example scenarios: load default IoT 2023 examples to quickly start experiments and demonstrations.
⭐ WebID broadcasting: log in to a personal data provider to broadcast your WebID from the app for identity-linked tests.
Advantages
✅ Practical for development and research, offering immediate tools to inspect and prototype semantic beacon use cases.
✅ Broad protocol support simplifies testing across common beacon formats without extra hardware changes.
✅ Built-in simulator and example scenarios accelerate proof-of-concept work and classroom demonstrations.
✅ Visual map output and automatic data fetching make it easier to relate linked data to physical locations.
Disadvantages
❎ Designed as a demonstrator rather than a polished consumer product, so the interface focuses on functionality over user-friendly polish.
❎ Requires a BLE-capable device and some familiarity with linked data concepts to get the most value from the tool.
Development Team
SemBeacon was developed by Maxim Van de Wynckel, a PhD student at the Vrije Universiteit Brussel, and targets researchers and developers working with semantic IoT beacons and linked data experimentation.
