Using Real Devices, Real Packets, and Real Open-Source Tools.

Bluetooth is much easier to understand when you start from a real device instead of a slide deck. In this session, we’ll take a small BLE-controlled RGB LED bar, reverse-engineer its services and characteristics, and observe how it reacts to reads, writes, and notifications. Using a Bluetooth scanner/explorer app and then a purpose-built .NET MAUI control app, I’ll show you how to move from “unknown device” to a clean, focused UI that controls real hardware. Along the way, we’ll explore practical BLE patterns and cross-platform abstractions using an open-source MAUI Bluetooth library, turning raw packets into something you can actually ship.

• Session format: Live demo–driven technical session
• Preferred duration: 45–60 minutes (content scales cleanly to either)
• Target audience: .NET / .NET MAUI developers with basic familiarity with C#; no prior Bluetooth experience required
• Technical level: Intermediate (concepts explained from first principles, applied to real-world scenarios)
• Live demos: Yes – reverse-engineering a real BLE device and building two MAUI apps (a generic BLE explorer and a device-specific control app)
• Hardware requirements: BLE-enabled laptop for the speaker; no special setup required for attendees
• Platform coverage: Android, iOS, macOS, Windows (via .NET MAUI)
• Code availability: All demo code and libraries shown are open source and will be available after the session
• First public delivery: Yes (newly updated session with a brand-new demo device)
• Recording-friendly: Yes
