Add kvaser-bridge Kvaser WebSocket bridge
Update tray.py Self signed cert for wss Update bridge.py IP display on UI Ws server Support socketcan for Linux Kvaser-ws bridge Tkinter gui Introduce a new kvaser-bridge tool that bridges a Kvaser CAN adapter to a virtual serial port speaking the slcan/Lawicel protocol. Update tray.py Update config.py Simplify CAN and websocket init In the React app, consolidate DBC cache handling and initialize the WebSocket service only after the DBC is loaded (keeps cleanup on unmount). These changes simplify startup behavior and avoid attempting privileged network commands from the bridge process. CAN decode fallback, signed ID support

DAQ Radio pecan dashboard
13+
```
14+
15+
## Prerequisites
16+
17+
- Python 3.10+
18+
- [Kvaser CANlib SDK](https://kvaser.com/download/)
19+
- tkinter (included with most Python installations)
20+
21+
## Install
22+
23+
```bash
24+
pip install -r requirements.txt
25+
```
26+
27+
## Run
28+
29+
```bash
30+
python src/main.py
31+
```
32+
33+
A small window appears with:
34+
- **Channel** - select which Kvaser CAN channel to use
35+
- **Bitrate** - CAN bus bitrate (default 500k)
36+
- **WS URL** - WebSocket URL of the dashboard (default `ws://localhost:9080`)
37+
- **Start/Stop Bridge** - toggle the connection
38+
39+
Click **Start Bridge** to begin streaming CAN frames to the dashboard.
40+
41+

46+
47+
# Windows
48+
pyinstaller build.spec
49+
```
