# bridge-serial

ESP32 ESP-NOW bridge with **USB/serial** uplink to the Pi (GPIO UART). Sync loop only — no asyncio, no Microdot.

```
bridge-serial/
  src/
    main.py       # entry
    settings.py   # /settings.json on device
```

Deploy:

```bash
cd bridge-serial
python ../led-tool/cli.py -p /dev/ttyUSB0 --src -r -f
```

No `--lib` required. Match `serial_baudrate` on the ESP and Pi (e.g. `921600`).
