My RFduino dev kit just arrived, and for my project I have to connect a few RFduinos via Bluetooth and light up certain LEDs attached to the RFduinos. If anyone could point me in the right direction as to where I can program them/how I can connect them, it would be GREATLY appreciated.


I am starting on a similar project (without the Dev Kit). Hooking the Bluetooth module to the RFduino is pretty straight forward, PWR to PWR, GND to GND, remember to cross the transmission wires: TX to RX & RX to TX.

In your void setup(), you need to start the connection:

Serial.begin(9600); // check your documentation to see the baud rate

In your void loop(), read or write to/from the bluetooth connection with serial write/read. Serial.read() or Serial.write()

Remember that Bluetooth is a communication protocol, not a controller. You don't mention WHAT you are connecting your RFduinos to using Bluetooth. You still need a controller capable of sending a signal to light up the LEDs using Bluetooth.

  • Thank you that is very helpful. I plan to use my iPhone as a controller, but I also want to make my own App. I don't want to use the pre-existing RFduino LED controller app. (the one on the app store) Dec 1 '15 at 18:33
  • Sweet! I'm doing the same thing with Android! However, life has put this project on hold for a while. Please keep me posted on your progress. Dec 1 '15 at 21:03
