Hi Freek, > I am trying to monitor the traffic between my linux system and an external > bluetooth system using the command "hcidump -i hci0 -w filename". I only catch > some traffic from the host to the external device, but nothing from the device > to the host. I analyze the file using wireshark. you need a newer Wireshark version. I remember it had some issues with correctly decoding the base packet types. Double check with btmon or hcidump that all traffic is actually in the file.
