Common Operations

Running in Development

bun run tauri dev

This command does the following in parallel:

  • Starts the Vite/SvelteKit dev server on http://localhost:1420
  • Compiles the Rust backend (first run takes several minutes)
  • Opens the Tauri application window

The frontend supports hot module replacement — changes to .svelte and .ts files appear immediately without restarting. Rust changes require a recompile, which Tauri handles automatically but takes longer.

First build warning: the initial cargo build downloads and compiles all Rust dependencies including GStreamer bindings. This can take 5–15 minutes depending on your machine. Subsequent builds are fast due to incremental compilation.

Building for Production

TauriOne of Tauri's dependencies, libc (a C standard library), is forward compatible but not backward compatible

The demo laptop has an old verison of linux so you need to use docker to build the app if you want to use it in it.

sudo docker run --rm \
    -v $(pwd):/app \
    -v tauri-cargo-cache:/root/.cargo/registry \
    tauri-ubuntu2204

For building the app in linux for the demo laptop use the command:

Testing Without Rover Hardware

You do not need a physical rover to develop or test the UI. The backend includes a full simulator.

Video Feeds

Fake camera

fake_camera_gstreamer/ — a GStreamer-based test source that sends H.264 RTP streams on the expected UDP ports (4500, 4501, 4502). It can be run from by running the following command from erc-software-basestation/fake_camera_gstreamer/

cargo run --bin fake_camera_gstreamer

Stream from Webcam

To test the video feed with your webcam open a terminal and use the following command.

gst-launch-1.0 v4l2src ! videoconvert ! x264enc tune=zerolatency bitrate=800 speed-preset=ultrafast ! rtph264pay ! udpsink host=127.0.0.1 port=4500

Dummy data streams (rover telemetry)

Once the app is running, go to /settings and use the simulator controls:

  • Start dummy general stream — starts the full multi-stream simulator sending fake IMU, GPS, arm, drive, and sensor data to the app over UDP. Use this to test all telemetry UI at once.
  • Start dummy IMU stream — starts an IMU-only stream with no jitter or packet loss. Use this for isolated IMU component testing.
  • Stop dummy general/IMU stream — stops whichever simulator is running.

The simulator runs inside the Rust backend so it works regardless of whether a rover is connected.

Connecting to the Rover

TODO

The base station listens for incoming UDP packets on 0.0.0.0:9000
