Unrecognized file format with 6LoWPAN Analyzer with PCAP #9

andreyferriyan commented 6 years ago

Hi, I try to make simulation using cooja. This is my specification:

  1. I create one rpl-border-router using sky mote
  2. I create 3 hello-world sky mote

I try to running 6LoWPAN Analyzer with PCAP. Everything is working fine and I can see the information from the radio messages. But after I save the file to pcap, wireshark or tshark cannot read it.

I try to fix it with pcapfix but I don't know if it is the right fix or not.

sim3.zip fixed_sim3.zip

Thank you for providing the files. sim3.zip (sim3.pcap) is a text file not a pcap file.

$ file sim3.pcap
sim3.pcap: ASCII text

$ head -n 5 sim3.pcap

Did you use "Save to file" menu on the radio logger tool in order to make a pcap file for your simulation? I got a similar file by that operation.

In fact, you don't have to do that. A pcap file is automatically generated with a file name starting "radiolog". You'll find some pcap files by the following command on the root directory of your contiki-ng repository.

$ find . -name radiolog\*.pcap

Could you try this command to see if you have pcap files?

Yeah, you right. I'm sorry. Yes, I got the pcap files on build folder.

Thank you.
