some bluetooth fun for long afternoon

i'm toying with my palm m125 and bluetooth sdio card.
connecting/disconnecting works fine, and i had only one crash on palm,
which is kind of miracle comparing it to 1.0 version of palm stack,
which i used before and which crashed nearly on every occasion. now i
have latest revision 1.7 from palm website.

i paired them without problem, but sdptool browse does not return
anything. have a look below. fun is that RFCOMM channels on palm seems
to be assigned to applications rathen than to common profiles, it seems,
because by trying i found out that channel 1 is bluechat (simple
chatting application) and channel 2 is blueboard (drawing sharing
application). can't find channel for obex :(
