Serial Communication plugin for Unity3D

Plugin extends C# API SerialPort.GetPortNames()

Main features

• Supports desktop platforms: macOS (+editor) and Windows (+editor)
• List all active serial ports
• Provide port name, description, hardware id

Compiling

• Plugin: see README.md from Unity native plugin repository
• Sample: Tested in Unity 2018.2.5

Usage

var ports = new SerialPorts();
// get ports count
var portsCount = ports.GetPortsCount();
// get first port info
var firstPort = ports.GetPortAt(0);
// search port by name
var arduino = ports.GetPortByName("/dev/cu.usbmodem14C1");
if (arduino.IsValid) {
    Debug.Log(arduino);
} else {
    Debug.Log("arduino not found");
}

Output example

Ports count: 3
Port #0: PortInfo '/dev/cu.serial0' 'n/a' 'n/a'
Port #1: PortInfo '/dev/cu.Bluetooth-Incoming-Port' 'n/a' 'n/a'
Port #2: PortInfo '/dev/cu.usbmodem14C1' 'Arduino (www.arduino.cc) Generic CDC' 'USB VID:PID=2341:0043 SNR=7543932383535160C1C1'
Port #3: PortInfo <Invalid>
