Bluetooth Virtual Sniffer (btvs.exe)

The Bluetooth Virtual Sniffer allows the user to view live HCI traces in the Frontline Protocol Analysis System, in the Ellisys Bluetooth Analyzer, or in Wireshark.

Note

Wireshark is recommended.

Bluetooth virtual sniffer command line options

btvs.exe [-Address 127.0.0.1] [-Mode Frontline|Ellisys|Wireshark]  [-Port 24352] [-Remote off|on] [-Service 1|2|3]

    Address     (Ellisys mode only) Specifies the IP address of the machine
                    running Ellisys Bluetooth Analyzer. (Default: 127.0.0.1)

    Mode        Optionally specify whether btvs.exe should generate traces
                    for Frontline, Ellisys, or Wireshark.

    Port        (Ellisys or Wireshark only) Specifies the UDP listen port of the
                    Ellisys Bluetooth Analyzer injection API\Specifies the TCP port
                    for Wireshark. (Default: 24352)

    Remote      (Wireshark only) Specifies whether Wireshark will be on the same machine
                    or run remotely. Off will try to start Wireshark on the same machine. (Default: off)

    Service     (Ellisys mode only) Specifies the HCI Injection Service.
                    1: Primary. 2: Secondary. 3: Tertiary. (Default: 1)

All of these usages require opening a command prompt or Powershell console and navigating to btvs application inside the extracted BTP folder.

Wireshark operation

Assumes Wireshark is installed.

  1. Run btvs.exe using the command prompt\PowerShell console:
    btvs.exe -Mode Wireshark
  2. If Wireshark is installed, Wireshark will automatically open.
    Otherwise, manually start Wireshark and provide the default TCP pipe as the interface:
    wireshark -k -i TCP@127.0.0.1:24352

Usage for Wireshark on separate machine

  1. Run btvs.exe using the command prompt\Powershell console:
    btvs.exe -Mode Wireshark -Remote on
  2. Run wireshark and pass in the ip address of the first machine and chosen port via command line parameters:
    wireshark -k -i TCP@<ip address>:<port>
    Note: port defaults to 24352

Ellisys Bluetooth Analyzer operation

Assumes Ellisys is installed.

Tool configuration

  1. In Tools->Options in the Ellisys Bluetooth Analyzer, enable HCI injection services on the Injection API tab.
  2. Configure recording options in Record->Recording options in the Ellisys Bluetooth Analyzer. If only HCI traces are desired, uncheck all of the options under Wireless Capture.

Ellisys usage

  1. Start Ellisys Bluetooth Analyzer.
  2. Select the HCI Overview (injection) overview tab.
  3. Click Record.
  4. Run btvs.exe in Ellisys mode on the machine to be traced:
    btvs.exe -Mode Ellisys
    a. Optionally, if the Ellisys Bluetooth Analyzer is running on a different machine, or if the listen port in Ellisys was changed, provide the Address or Port on the command line (see Command Line Options, above).

Frontline Protocol Analysis System operation

Assumes Frontline is installed.

Frontline Protocol Analysis System usage

  1. Run btvs.exe -Mode Frontline on the same machine using the command prompt\Powershell console.
  2. Click the Start Capture button (Red button on the tool bar).
  3. Click View->Frame Display to show HCI traces.
