Hi to all,
I published my project on playground:
http://www.arduino.cc/playground/Code/2B

It is a simple communication protocol between python and arduino...

Hope it helps,
Marco Sangalli

Hi,
open 2 console (A,B)

(A) rfcomm connect 0 (do not use bind)
(B) minicom -s

From console (B) setup serial port and speed, then exit the dialog and go to "EXIT" and press enter
Now you can test if serial works or not...

I will find a solution for sketch...

Regards,
Marco

Hi,
I successfully uploaded the HEX file to ArduinoBT on Ubuntu Feisty
You have to configure and use the "rfcomm0" (I tried with higher port but it fails to upload)

Press reset button on ArduinoBT and upload the file (use uisp under tools folder):
./uisp -v=4 -dpart=atmega168 -dprog=stk500 -dserial=/dev/rfcomm0 -dspeed=115200 --upload if=<FILE.hex>

About sketch, you can create a symlink to ttyUSB0 like:
cd /dev
ln -s rfcomm0 ttyUSB0

Best Regards,
Marco Sangalli

I'm using arduino Bt with Linux... without problems...
