I've noticed a strange behaviour in the last versions of Bluez (at least >= 4.19) when retrieving services via the DBus method in org.bluez.Device.DiscoverServices: the XMLs returned by this DBus call have the "value" attribute of _every_ "uuid" element set to "0x0019", for the records with 16-bit uuids. 128-bit uuids are not correctly represented too, seeming to be 4-bytes right-shifted. When performing service discovery via sdptool with the --xml parameter the output is correct. I'm attaching two examples for the two cases I experienced this in Bluez 4.19 shipped with OpenSuse 11.1, and in Bluez 4.25 packaged for Ubuntu 8.10 (unofficial) at http://ppa.launchpad.net/blueman/. This does not happen in Bluez 4.12 shipped with Ubuntu 8.10 I'm posting here this report as I didn't find a Bluez bug tracker and the bug seems to be distribution-independant Thanks for your attention Daniele Benucci -- Grabel's Law: 2 is not equal to 3 -- not even for large values of 2.
