"Right now, the Arduino isn’t reading serial data from the BLE module, it’s pretty much working as a pass-through for whatever the BLE module says. It reads the value of three of the BLE’s GPIO’s to control each color of the LEDs. In the future, it should read serial commands from the UART and have a big list of awesome things that it’ll do. Naturally."
