Using a Y cable in that way could also be dangerous though. I seem to recall seeing something about not using ELM327 with a plugged in computer, but you could try it with a meter first, then an expensive device. Thanks for testing, Ben. I guess the bluetooth version might be better, then, as the FR could be charged in the normal way via USB whilst logging via BT.

Jeff, I just went out and tested and the ELM327 does not charge my phone in host or device mode. It may be possible to use a Y usb cable to charge and talk to ELM327 at the same time if you need to log for longer than the FR battery will last. Using a Y cable in that way could also be dangerous though. I seem to recall seeing something about not using ELM327 with a plugged in computer, but you could try it with a meter first, then an expensive device.

ELM 327 Bluetooth OBD2
Has anybody tried their GTA0[24] with the above device? Regards Jeff ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: ELM 327 Bluetooth OBD2
I've used a usb ELM327 based scanner with my GTA02. I have successfully read codes, cleared codes, and watched sensors. I use this program: http://code.google.com/p/pyob2read/ but I strip out references to the graph library is I couldn't find it for GTA02. I cant seem to find my modified script or I would share it.

Re: ELM 327 Bluetooth OBD2
GTA02 seems to be able to supply a lot of power. I have used mine to charge a Petzl core battery. The charging was less important than using the GTA02 to reprogram the battery's internal regulator. It had no problem powering the ELM327, but I would hope that is getting the power from the car's electrical system.
