ELM 327 Bluetooth OBD2

[Benjamin Deering]

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.
