Serial Port Utility Pro

Powerful Serial port utility in Unity3D for Android, Linux, Mac OS, and Windows.
This is extended plugin for Unity that gives developers an easy to use powerful computer communication solution.
When you use this plugin, you can spend time on important other works.


The connection of devices should become more straightforward.
Applications: M2M, IoT, PLC, Amusement Control, Hobby Device, Deep learning, FPGA UART.

  • Implement PC-to-PC communication in Unity easily via serial ports.
  • Implement PC-to-Microcontroller(Arduino, Ftdi, Microchip, Cypress, Silicon Labs, etc.) communication in Unity easily via serial ports.
  • This plugin can specify the unique ID of a device and can run a device. The stable systems development is possible.
  • Support cross-platform with Windows, Mac, and Android.
  • This plugin does native processing asynchronously and is optimizing to Unity.
  • An event-driven function for data reception. By this, the design of software becomes very easy.
  • There is a system which puts a JSON type into the variable of a class directly.
  • In this plugin, after carving a character string automatically, these are converted to List<string> or Dictionary<key, string>.
  • The native code implements I/O. Late and heavy processing “.NET – System.IO.Ports” is unnecessary.
  • Error detection by physical disconnection of a device.
  • USB, PCI, EmbeddedUART physical interface supported.
  • Bluetooth SPP (Virtual COMPort) supported.
  • TCP Serial Port Emulator (Server mode and Client mode) supported.


  • Unity 5.5 and above, Unity 2017.x, Unity 2018.x (It can be used for both Personal and Pro.)
  • Windows 7 and above (32-bit and 64-bit)

  • Linux OS -> We will support in the future, it will be released in early 2019.
  • Android 4.1(Jelly Bean) and above
  • SerialPort Device(USB, RS-232C, RS-485)
  • Bluetooth Device
  • Ethernet, Wi-Fi (TCP/IPv4)
