Thanks for the comments. The setup.sh script should have taken care of those things, but it also has some errors that need to be fixed so it may not make those changes before it crashes.
I added some issues to the code last week and then fixed them. I should add some more. The biggest things right now are the work that [Team BOSSA] and [Team USB] will be doing. If you can help there at all, please do that. Specifically BOSSA needs to be compiled for windows and mac and I need the binaries.
One thing that can be done for the library is reorganization. Weirdly I'm terrible at figuring out how to group and organize things, which is reflected in my code and in my apartment (it's messy). I would say just poke around with the code and get to know it for now.
Also see this document for the rough idea on system operation. I don't have auto-pairing yet, which would be a nice feature. https://github.com/flutterwireless/FlutterWirelessLibrary/blob/master/extras/Flutter_diagram.pdf
There is an XML file adjacent to that pdf that can be edited at www.draw.io.
I will try to figure out what you guys can do and get back to you. If you can help with USB, please see that thread and download the materials there. Thanks!
