VitalBLE delivers 4.5 Mbps throughput - a 67x improvement over standard implementations:
- Before: 81KB in 10 seconds (0.067 Mbps)
- After: 81KB in ~150ms (4.5 Mbps)
- Ultra-High Performance: 4.5 Mbps BLE data transmission
- Windows Native: C++/WinRT implementation with JNI bridge
- Configurable UUIDs: Heart Rate Service by default, fully customizable
- Modern Testing: JUnit 5 test suite with comprehensive coverage
- Production Ready: Maven library with JaCoCo code coverage
- Easy Integration: Simple Java API with singleton pattern
