Without knowing which BT module you are using it will be a little difficult to help, but. As mentioned above using the BlueSMiRF board and some jumper wires you can attach

  • 5v to PWR
  • (-) to GND
  • tx to RX - I
  • rx to TX - O

If you have a specific BT module you are working with update your question and we can try to be more helpful.
