Scan, connect, and interact with many Bluetooth Low Energy devices at once. Design visual workflows that run on real hardware. Simulate, document, and ship — all from a single elegant app.
Signal Hub treats every BLE connection as a first-class citizen. Scan the room, connect to multiple peripherals in parallel, and switch between them without losing context. Read, write, and subscribe to characteristics with one click — and watch traffic stream in real time.
Drag, drop, and connect nodes to compose any BLE flow — handshake, OTA, telemetry, edge cases. Each node is a real BLE action. Hit run, and Signal Hub executes the entire workflow against your device, with full visibility into every step.
Organize devices, workflows, and notes into workspaces. Each one is a self-contained context — switch projects with a click. Share a workspace with a teammate and they pick up exactly where you left off.
Connect a workflow to physical hardware in seconds. Pick a discovered peripheral, bind it to a node, and watch the workflow drive the device for real — no scripts, no fixtures, no detours through a terminal.
The built-in BLE simulator stands in for any peripheral. Mock services, characteristics, and responses — including the gnarly edge cases that real hardware refuses to reproduce. Build, test, and demo your workflows before the prototype hits your desk.
Export any workflow as a high-resolution PNG, a screen recording, or a compact summary — ready to drop into a PR, a spec, or a customer report. Documentation becomes a by-product of building, not a chore.
Workflows rendered at retina resolution, ready for documentation, PRs, or slide decks.
Record a live run with all device traffic overlaid. Perfect for demos and bug reports.
Every workflow run produces a structured summary — steps, timing, results, errors.
Concurrent connections, workflows, simulator, export — all in motion. The fastest way to feel what Signal Hub actually does.
Signal Hub is in private beta on macOS. If you spend your days talking to BLE peripherals, we'd love to hand you the keys.
