Cool. can you show me output of 'btconfig -vvvv' please?  The kernel code
attempts to DTRT by reading the features and constructing the best value
but maybe the features lie (it has been known though I haven't seen a
device that does that). I'm not sure but using this value may cause slower
data transfer in a congested bluetooth area since it reduces the options

The obexapp manpage has some information about extracting contacts, they
don't show up in the directory scans and I'm not sure which sync programs
work and how well as I've never investigated that (please let me know if
you get something working, we could add it to the guide)

Notes are just plain text files but the filename doesn't always come
through. If I send a note from a nokia phone to my laptop I just get
Nokia.txt appearing - for the other direction, the phone keeps a list of
notes someplace private. On a windows mobile phone you are just in the
'Bluetooth Share' folder and see whatever is there and I think filenames
are remembered.

in my /etc/rc.conf I use


and additionally you probably need to set the <Object Transfer> bit
0x100000 in the class of device setting as some Nokia phones filter the
inquiry results before displaying the list. I have:

        class: [0x12010c] Laptop Computer <Networking> <Object Transfer>

Oh, and of course you must be discoverable (enable inquiry scan)
