# DongLoRa Mux (Rust)

USB multiplexer daemon — lets multiple applications share one DongLoRa
dongle simultaneously.

## What It Does

- Owns the USB serial connection exclusively
- Exposes a Unix domain socket (and optional TCP) speaking the same
  COBS-framed protocol
- RxPacket frames broadcast to all connected clients
- StartRx/StopRx reference-counted across clients
- SetConfig locked once set (single client can change freely)
- Automatic dongle reconnect on hot-plug
- No panics — enforced by clippy deny lints

## Running

```sh
just run                                    # start the mux daemon
just verbose                                # start with verbose logging
just run -- --tcp 5741 --port /dev/ttyACM0  # with options
```

## Depends On

- [clients/rust](../../clients/rust/) — the `donglora-client` library
  (protocol types, COBS framing, device discovery)
