Hello! I have Nexus 4 with original Android 4.3, everything stock. I tried to use Torque Pro (latest version) with my Nexus 4 and ELM 327 (mini) with my Passat B5 1.8T but it didnt works correctly. Nexus is pairing with OBD device, but cant connect with my car (blue car indicator is flashing and I think its something like connection timeout?). Second question is that i must all the time pairing my OBDII with Nexus 4 when I restart program, is this possible to constant pair or its normal and all the time i must repeat the "1234" code? Thanks for anwser.
