Bluetooth ETL parse (BTETLParse.exe)

The Bluetooth ETL parse tool extracts HCI traces from ETL files containing compressed Bluetooth data.

This tool is meant for parsing ETL files collected using the Bus tools for Windows Repo on GitHub.

Tracefmt is a way to parse additional logs from the ETL file.

ETL parse command line options

Usage: btetlparse [-cfa <output_cfa_filename>] [-hci <output_hci_filename>]
[-pcap <output_pcap_filename>] [-pcapng <output_pcapng_filename>]
[<input_etl_filename>] [<additional_input_etl_filenames>]

    -cfa through -pcapng flags parse the etl file into different file types.

    -cfa <filename>         Data file readable by Frontline protocol analyzers.

    -hci <filename>         Data file in plain text format.

    -pcap <filename>        Data file readable by Wireshark protocol analyzers.
        
    -pcapng <filename>      Data file readable by Wireshark protocol analyzers.

    <input_etl_filename>    The is the filename of the ETL file we are trying to parse.
                                Default is c:\temp\btetw.etl

    <additional_input_etl_filenames>    BTETLParse can parse multiple ETL files at a time.

ETL parse Usage example

Move the ETL file collected by Bus tools for Windows Repo on GitHub to the same folder as BTETLParse within the extracted BTP package. Then run:

• btetlparse -cfa BthTracing.cfa -hci BthTracing.hci -pcap BthTracing.pcap -pcapng BthTracing.pcapng BthTracing.etl from a command prompt/PowerShell console

This command parses BthTracing.etl into all available filetypes. See Command Line Options above for descriptions of each file type.
