I hate to break it to you but your thread title was rather misleading :) There is a difference between OBD and OBDII. Lots of older cars (I think predating year 2000) runs on OBD system which included my car.

btw. it isn't also OBDII which is used there. The ELM chip it the adapter is doing the biggest job, like checking the sent checksum from the OBDII interface ;)

Sure this could maybe not be the right place for asking that, but which output did you get when connecting the ELM327 device via serial connection?
Need the information to make my modules compatible to other devices.

Here is how to connect to your device using hcitool and python using pybluez:
1. Find out which bluetooth address your adapter has
Code:

hcitool scan
2. Launch the python console
Code:

python
3. import the pybluez modules
Code:

import bluetooth
3. create a bluetooth rfcomm socket
Code:

sock=bluetooth.BluetoothSocket( bluetooth.RFCOMM )
sock.connect((<btaddr>, 1))

4. get the message from the socket
Code:

sock.recv(2048)
5. close the connection
Code:

sock.close()
I expect something like: "\r\rELM327 v1.4\r\r>"
Can you confirm this?

I'm not too familiar with all the inner workings but the bottom line is that OBDII is incompatible with OBD and vice versa :). its somewhat a shame because it means that for car enthusiasts who have to much smaller sized budgets have to get appropriate and different equipment to suit what matters on hand.

For now I guess I don't have much of a choice but to use whatever software that is fully compatible with OBD and it only works under windows called efilive.
