Can you un-pair your device, and then re-pair after running the bind and
sdptool commands? I believe there's some early-setup that occurs; your
phone may be assuming that your computer cannot act as an rfcomm device,
and thus there may be a bit of confusion there.
Additionally, please confirm you only have one bluetooth device [hcitool
can tell you this, I think]. obdsim just assumes that the first
bluetooth device it can find is the one it should use, which may not
always be correct [although most folks only have one bluetooth device,

Yes, these are typical symptoms of it not-working. obdsim chatters every
10 seconds or so, saying how many samples it's produced. Zero indicates
that nothing's talking to it in any way it can recognise.
It might be good to check that obdsim isn't seeing something that it
just doesn't recognise; can you run obdsim with the logfile option, and
see what's in it?
