When I open any of my bluetooth "*.cap" files with wireshark. Then Wireshark
never decodes the BTSDP information in my packets. 

All the HCI decoders and other stuff works fine but the BTSDP decoder never
works at the first packet open.

However I have found a workaround if I do the following sequence the BTSDP
module will be loaded:

1: duple click on the .cap file so wireshark opens the file.
2: choose file->open recent->[click the first entry (ie. the file which is
currently opened)]

now the BTSDP module starts decoding SDP information from the l2cap packets.

However it often complains about the SDP packets is malformed.

Of relevant information I can mention that the packet format I use for dumping
my information from the bt stack into the file is pcap formatted.

The same problem seems to be related for other dissectors (I have some
temporary dissectors for AVDTP, AVCTP and AVRCP) However I'm sure the problem
is not related to those dissectors because I have tried to remove them from the
plugins directory so their not loaded at all.

Can you please help and/or advice me how to solve this problem?

Regards,

Henrik Arendrup
