I want to build a wearable device for a dancer using the Lilypad and I need to first send the programme from my Mac to the Lilypad board and then transfer the data read by sensors back to my Mac.

I have been using a hc-06 module very successfully. http://www.dx.com/p/hc-06-wireless-bluetooth-serial-pass-through-module-for-arduino-works-with-official-arduino-board-238364#.VLg153WjlIc

Connect pins to +5v, Gnd, and digital pins 0 and 1 (rx & tx).

Do not try to connect to USB and this at the same time, as communication will get garbled.
