UART boards (CP2102 bridge) keep the serial port alive across ESP32 resets, so the mux never detected the board rebooting. Now the writer sends a keepalive Ping every 5s of idle and declares the dongle lost after a 2s timeout. On reconnect, saved radio config and RX state are re-sent to the dongle so connected clients continue working without re-establishing state.
DongLoRa Mux (Rust)
USB multiplexer daemon — lets multiple applications share one DongLoRa dongle simultaneously.
Install
cargo install donglora-mux
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)
- Single-instance enforcement via file lock (stale sockets auto-cleaned)
- Automatic dongle reconnect on hot-plug
- No panics — enforced by clippy deny lints
Running
donglora-mux # start the mux daemon
donglora-mux --verbose # start with verbose logging
donglora-mux --tcp 5741 --port /dev/ttyACM0 # with options
Depends On
