The bluetooth communication was between an application of a normal user and the device. I used hcidump from the same user. Now that I use hcidump as root I get all the traffic. Silly mistake. I would propose to put some text in the man page of hcidump about using the command only as root. Maybe it should be installed in sbin instead of bin. -- fr.gr.
