# Radiotap Decoder in Java #
http://bertrandmartel.github.io/radiotap-decoder-java/
Last update 04/05/2015
Will decode any radiotap formatted byte array according to specification in http://www.radiotap.org
Following field will be implemented later:
* VHT field type decoding
* MCS field type decoding
* FHSS field type decoding
* AMPDU field type decoding
USAGE
The following usage show how to parse a pcapng file (from Wireshark) that contains Packet with Radiotap headers.
You can use
* the jnetpcap library
* my own lib in http://bertrandmartel.github.io/pcapng-decoder-java/ (pcapng-decoder-java)
You dont have to take the jar to you it is already in lib folder
COMMAND LINE SYNTAX
``java -cp ../lib/pcapngdecoder-1.0.jar:radiotapdecoder-1.0.jar fr.bmartel.radiotapdecoder.main.DecodeMain -f ../radiotap_file/exemple.pcapng -v``
-f : input file
-v : verbose, will show all section parsing content
This exemple is launched from release folder
PROGRAM SYNTAX
``byte[] radioTapData = packet.getPacketData();``
``RadioTap radioTap = new RadioTap(radioTapData);``
You can then look at all fields that are in the radiotap data with ``radioTap.getRadioTapFlagList()``
Go check ``fr.bmartel.protocol.radiotap.inter.IRadiotapFlags`` interface to see all list.
``radioTap.getRadioTapFlagList().getRadioTapData()`` will give you all the data you can grab according to flags above.
Go check ``fr.bmartel.protocol.radiotap.inter.IRadiotapData`` to see all data available.
