udev-serial

Usage

const udevSerial = require("udev-serial");
 
var serial = udevSerial({
  DEVNAME: true,
  ID_MODEL_FROM_DATABASE: /UART Bridge/,
  SUBSYSTEM: "tty"
}, {
  delay: 0,
  baudRate: 115200
});
 
serial.on("open", function() {
  console.log("port opened");
});
 
serial.on("data", function(data) {
  console.log(data.toString());
});

udevSerial(descriptor, [ opts ])

descriptor is an object used to match against udev events. It's keys may be a String, Number, RegExp or true/false. Note: Number is coerced using == as udev event values will always be strings.

opts.delay is the time in milliseconds that should be delayed from the udev event to opening the serial port.

opts.baudRate baud rate passed to the serial port constructor.

opts.wait if set to true udev-serial will not check current devices.

opts.noConnect if set to true udev-serial will not automatically connect.

opts.noReconnect is set to true udev-serial will stop the udev.monitor

opts.SerialPort Override SerialPort constructor. Used for testing.

opt.udev Override udev module. Used for testing.

CLI

Usage: udev-serial -v key=value,... {OPTIONS}

    --baud,  -b Baud rate for node-serialport

    --value, -v Set value to match udev events against
                example: --value DEVNAME=true

    --list,  -l List devices
                Can filter with -v

    --return,
             -r Key to return on match

    --json,  -j Return JSON (ignores -r)

CLI usage example

$ udevserial -r DEVNAME -v DEVNAME=true -v ID_MODEL=/duino/ -v SUBSYSTEM="tty" -l
/dev/ttyACM0
$
