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 
 One of Tauri's dependencies, libc (the 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. The first time you build you have to build docker first: 
 sudo docker build -t tauri-ubuntu2204 . 
 For building the app in linux the subsequent times for the demo laptop use the command: 
 sudo docker run --rm \
 -v $(pwd):/app \
 -v tauri-cargo-cache:/root/.cargo/registry \
 tauri-ubuntu2204 
 You don't have to docker build every time, just the first time and if you change anything in the dockerfile 
 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. 
 Linux 
 gst-launch-1.0 v4l2src ! videoconvert ! x264enc tune=zerolatency bitrate=800 speed-preset=ultrafast ! rtph264pay ! udpsink host=127.0.0.1 port=4500 
 Windows 
 gst-launch-1.0 ksvideosrc ! 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 the address set on lib.rs, must set static address in laptop settings
