For a little project I'm doing I needed a way to do Bluetooth LE with my Netduino Plus, and I found the nRF8001 by Nordic.
Turns out it's a nice chip with good documentation (as most Nordic stuff tends to have).
However, I found out there wasn't a .NET library written for it yet!
So I decided to write one and put it on GitHub for everyone to use, because I can't imagine other people aren't interested in using this great BLE device.
It may be a little premature, seeing how most functionality isn't implemented yet, but I'm expanding this library every time I need more functionality from the nRF8001. For now at least, it is possible to get the device initialized and connect to a peer device.
I hope someone can make good use of it!
