more on builtin bluetooth

so the external bluetooth dongle is now working for PAN.

But lets look @ the built-in one a bit more.

I see that it uses /system/bin/sdptool to configure.

And that in init.rc, it does somethings like setup HFAG (Handsfree audio gateway), HSAG (Headset), OPUSH (share business cards and such), PBAP (Phone book profile).

So it should be possible to extend this with DUN (Dial-up networking), NAP (for networking), PANU (personal area network).

Sure enough, after doing the sdptool adds for the new services, they show up. I’m not sure if this is sufficient or not.
