Bluetooth Research

I'm deciding to use Bluetooth as the wireless data transmitting and receiving to the Smartphone. First of all, i already decided the hardware that i should used. Below are the bluetooth hardware that used for my PPG interface with the smartphone:

1. Arduino Uno R3, which you can find here, http://www.myduino.com/index.php           route=product/product&path=37&product_id=271
2. Xbee Shield for Arduino, which you can find here as well, http://www.myduino.com/index.php?route=product/product&path=40&product_id=108
3. Bluetooth Bee, this is the link, http://www.myduino.com/index.php?route=product/product&path=50_56&product_id=105
