Device discovery/pairing issue w/ BlueZ on Debian

Device discovery/pairing issue w/ BlueZ on Debian

[Clemens Vasters]

I’ve got a cheap Bluetooth car diagnostics dongle (OBD-2, ELM327) that
gets discovered by and pairs with Windows 8, Windows Phone 8, OSX
Mountain Lion, iOS 6, and Android Jelly Bean.

I can’t get it to be either discovered or paired with BlueZ on Debian
Wheezy on my Notebook (bare metal, ThinkPad W510) or Raspbian Wheezy
on the Raspberry Pi. On the latter I even went so far to pull the
source for BlueZ 5.8 and install it from source. No dice.

I’m pretty puzzled about this. How would I go about debugging or,
rather, what data do I need to gather (and how) for someone to help me
with this.


Thanks
Clemens

If this isn't the right list for this sort of question, could someone
point me to a more appropriate one?

Your description of the problem is a little vague. Which tools did you
use on BlueZ 5.8 to attempt to discover/pair with the device? Which
errors did you see (if any)?

Wheezy comes with kernel 3.2 so BlueZ 5 is no option there (at least on stock
kernel).
