The LiveLink Simulator (Develop → LiveLink Simulator) — “LiveLink Studio” — lets you simulate real-time communication between the user/app side and the device side, live and independently. Test your command and telemetry flow without physical hardware.
LiveLink Simulator with both sides live

LiveLink Simulator — the user/app side and device side connected over the secure relay, exchanging live traffic.

Two sides, one channel

The studio splits into two connected panes: Each side connects with its own ID (a user/session ID on one side, a device ID on the other) so you can watch traffic flow in both directions.

What you can do

  • Connect both sides and see live traffic in each log
  • Send a command from the app side as JSON — for example:
  • Send from device — reply with a payload, e.g. { "status": "ok", "value": 1 }
  • Use presets to load common command shapes
  • Add indicators in the Visualizer to map a command to a visual
  • Beautify the JSON logs for readability

When to use it

  • Validate your command/response format before touching hardware
  • Debug what the device should send to drive a widget
  • Demo the product’s behavior with no device connected
