Hi. nice program and just in time. I received my obdII BT dongle from dealextreme and tried it out with my n900 and pyobd.
Up till now I had little luck in connecting with my BT device.
after pairing the device, clicking "connect to ECU" and waiting for 30 seconds or so, I get the message "Error can't connect".

the last lines in the terminal output of pyobd (version 0.9.2-11) say:
...

does anybody have an idea what is wrong?
Thanks in advance,
Farid
