Hi, I have a Udoo X86 running Windows 10. On this platform I run a Unity 2017.3 program, communicating with the onboard Arduino (Intel Genuino) via the SerialPort. The problem is, that communication from Unity to Arduino is working flawlessly, but Unity is not receiving any data from the Arduino. I get TimeoutException [..] at System.IO.Ports.WinSerialStream.Read (no matter how long I set the timeout value). Strangely, if I test the setup with RealTerm, I do get the correct values from the Arduino. (And needless to say, when I run the Unity program on my PC with an Arduino Uno connected, it works without any problems). I have tested with baud rates 9600 and 115200, but to no avail. Any ideas on what might be the problem?
