HoloLens Bluetooth Ports
I'm facing the problem, that I can't use the SerialPort Class in my WSA UWP HoloLens app, to read bluetooth input, because the Unity compiler complains the following, when I'm trying to build:
error CS0234: The type or namespace name 'Ports' does not exist in the namespace 'System.IO' (are you missing an assembly reference?)
Any help about fixing this is, or alternatives is greatly appreciated.
Thank you in advance,
