Serial Port Utility Pro

Powerful SERIAL PORT utility in Unity3D for Android, Linux, Mac OS, and Windows.
This is an 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.
Implemented at a reliable OS level without using the C # .NET serial communication class.
Applications: M2M, IoT, PLC, Amusement Control, FA, Hobby Device, Deep learning, FPGA UART.

  • Implement Computer-to-Computer communication in Unity easily via serial ports.
  • Implement Computer-to-Microcontroller(Arduino, Ftdi, Microchip, ESP32, mbed, 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, MacOS, Android and Linux.
  • 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 class or Dictionary class.
  • 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.
  • Support Modbus for industrial systems.
  • Support VR HMD(Meta Quest)
