Serial ports for Tauri 2 apps

Desktop COM/tty ports, USB-serial adapters on Android, and serial over TCP or Bluetooth LE — including on iOS.

What you get

One API everywhere
Open, stream with watch(), read/write, line settings, modem lines, hotplug, auto-reconnect.
Modems built in
A native AT command queue with structured results, URCs, SMS (PDU) and GSM 07.10 / 27.010 CMUX.
Android without Java libraries
USB-serial drivers in Rust (FTDI, CP210x, PL2303, CH34x, CDC-ACM, …).
Network and radio transports
tcp://host:port to a serial bridge, ble://<id> to Nordic UART devices.
Rust backend
The same operations from your Tauri backend through the managed SerialPort state.
Generated reference
Every method, type, Tauri command and permission, built from the sources on each release.

Open a port, watch it, write to it

List the ports, open one and stream incoming data with watch(). Binary data, AT commands and auto-reconnect use the same port object.

Quick start Upgrading from v3

main.ts

import { SerialPort } from "tauri-plugin-serialplugin-api";

const ports = await SerialPort.available_ports();   // { "/dev/ttyUSB0": { type: "USB", vid, pid, … }, … }

const port = new SerialPort({ path: Object.keys(ports)[0], baudRate: 115200 });
await port.open();

const handle = await port.watch({
  onData: (text) => console.log("rx", text),
  onDisconnect: (reason) => console.log("gone:", reason),
});

await port.write("hello\n");

await handle.unwatch();
await port.close();
