Hi Product Hunt 👋 I'm excited to launch Signal Hub today! Signal Hub started from a frustration I kept running into while working with Bluetooth Low Energy (BLE) devices. Existing tools were great for manually inspecting devices, but as soon as I needed to test repeatable scenarios, coordinate multiple devices, simulate peripherals, or document complex workflows, I found myself writing custom scripts or juggling several tools. I built Signal Hub to make BLE testing and automation visual. With Signal Hub, you can: • Scan and connect to multiple BLE devices simultaneously • Build visual workflows that run on real hardware • Simulate BLE peripherals before prototypes are available • Automate repetitive testing tasks without writing code • Export workflow diagrams, screenshots, and video documentation It's designed for firmware engineers, mobile developers, QA teams, hardware startups, and anyone working with Bluetooth LE products. This is the first public launch, and I'd love to hear your feedback: • What BLE tools are you using today? • What's the most painful part of your BLE testing workflow? • What features would make Signal Hub more useful for your projects? Thanks for checking it out, and I'm happy to answer any questions!
