Over the Christmas break I was trying to get a Crazyradio dongle working as a communications gateway for an IoT project I was building.
I hit a few problems getting the CrazyRadio dongle to work in my application. But, as it came with a Crazyflie Nanocopter and I had spent a bit of time looking at the communications protocol.....
I used a Netduino 2+, elecfreaks joystick (with mods), Seeedstudio base shield and thumb joystick.
Next steps are to add support from "trimming" and advanced flight modes.
