I'm quite a beginner to Wireshark and I got problem using it, I searched the wireshark wiki but seems no promising results. Hopefully I can get some help here.
I am trying to analyze the network traffic between LG smart watch and Android phone, which all go through bluetooth channel. Now I have got the network traffic log file and I can view it by running wireshark <log_file_name>. Problem is how can I extract and retrieve data, or even just remove the bluetooth header and get the original network layer packet, because I can parse the IP layer packet but bluetooth packet is not what I want and what I understand.
