I'm new to the RFDuino. I recently bought one and I downloaded the Arduino 1.5.2 IDE, the RFDuino 2.2.2 Library, and the drivers for the USB Serial Port. However, whenever I try to choose the board in the Arduino 1.5.2, the RFDuino is not an option. I thought, maybe I just need to plug it in and try, but that didn't work either. Any thoughts on why it won't show up?
