Hello bluez,
I own an Anycom GP-600 GPS Receiver. This receiver might have a broken
SDP stack. I use SuSE Linux 9.3.
When browsing the device using the sdptool browse command, it fails.
However when using Konqueror to browse the SDP-record on the same
distribution it works fine.
The difference between kde and sdptool browse seems to be, that kde uses
a 32 bit UUID, while the sdptool uses a 16 bit UUID.
Is there any chance that bluez could handle such trouble more gracefully
and issue a waring? I remember prior Bluez versions had been working
slightly better.
Below you find the dumps for browsing with KDE and sdptool.
Br,
Michael
Browsing with KDE seems to use 32Bit UUID:

it simply means that this device has no public browse group. That is not
a bug. Try "sdptool browse --l2cap <bdaddr>" and see if this works.
