This is super frustrating, there are old/different libraries and code all over the place (this site, tutorials vs. forum, github - how about one page, about getting started, with the most recent downloads and correct examples - and put that under the predominant "Tutorials" link on the main site, instead of having to hunt through the forums.
I started here: http://community.flutterwireless.com/t/getting-started-with-the-flutter-basic-and-flutter-pro/216
Then tried this: http://flutterwireless.com/tutorials/003.html
First problem is serial doesn't work, seems that after board programming then the COM port disappears
Tried the later examples anyway and then on compile I get: class Radio has no named member begin.
In the end all I really want to do is send button presses from one flutter to match output LEDs connected on another. But there is nothing that shows how to do that simply, and even the examples I can't get to work.
Using the latest IDE: 1.8.5
Loaded boards by adding the URL to boards manager
Loaded library exploding the Flutter_US.zip to the library's folder
This whole kickstarter thing isn't just about making a "thing" and putting it out there - there HAS to be good documentation and support for people to adopt and actually use it - which today is non-existent.
