:) good. basic stuff works :)

hmmm... looks familiar... i think MS Bluetooth keyboard/mouse
also do not respond to "browse" command. Could you please try
to "search" for the specific service?

% sdptool search --bdaddr m123_bdaddr [--tree] SERVICE

where SERVICE one of the following:

	SP DUN LAN FAX OPUSH FTRN NAP GN HID CIP

or you also can use UUID, i.e 0x1002

please try "search" and let me know if it works. if that does
not work then you somehow should know RFCOMM channel number :)

well, something on Palm *is* responding to our request and
tells us that nothing about services :)

everything looks great. if you can establish baseband connection
(and you can) than its not a radio problem anymore. both devices
can send and receive data thus the problem is somewhere else.
