Hi there!
found this obduino thing going and tought... I have a bluetooth OBD scanner with ELM327 chip. loking around shematics I connected ELM's 18 and 17 pins to Arduino Tx and Rx, but all I get is ISO9141 Init..... Failed.
i have not put it in car, just bench testing, could it be that it fails to connect because it is not connected to car? (Yes, I added +12v to OBD reader)
or it is not enough to just connect tx and rx?
I cannot add pictures
thanks
