Lo tengo que conectar en el arduino shield

Y esto es para comunicarlo desde linux ...

As seen in http://arduino.cc/forum/index.php?action=printpage;topic=101452.0

Una vez conectado, en linux:

Remove the pairing (ubuntu 12.04 LTS)
Reboot box
hcitool scan
rfcomm bind 0 00:12:02:28:71:34 1
screen /dev/rfcomm0 9600 #This will prompt you for the pairing password and I also noticed the LED went solid rather than blinky.
screen /dev/rfcomm0 9600
rfcomm release 00:12:02:28:71:134

run the following just once after boot, and note AT commands cannot be run after this is paired
hcitool scan
rfcomm bind 0 00:12:02:28:71:34 1
