Update the Vector Vario

We are constantly improving the Vector Vario’s embedded software, whether to add new features, enhance existing functions, or fix issues. It is strongly recommended to keep your Vector Vario up to date to benefit from the best performance..

Software version identifiers (e.g. v1.32c) follow a major.minor(beta) structure:

  • The first number identifies majorchanges in the software (e.g., v1.00, followed by v2.00);
  • The second number identifies minorchanges, with improvements or new features (e.g., v1.00, then v1.01 and v1.02);
  • It may be followed by a letter identifying a test version (beta), which is released before the final version (e.g., v1.32b is released before v1.32c, and both are released before the final version v1.32).

From the Vector Vario Configurator :

  • Connect your Vector Vario to the Configurator;
  • Go to the Additional settings tab > Connected Device Information > Firmware Version.

From a config.vv file:

  • Switch off your vario;
  • Take the microSD card out from the back of the Vario and access it on a computer, tablet, or smartphone;
  • Open the config.vv file and find the line starting with FirmwareVersion.

From an IGC file:

  • Open an IGC file generated by your Vario in a text editor;
  • Find the line starting with HFRFWFIRMWAREVERSION.

Via Bluetooth (BLE) :

  • Connect your Vector Vario to the Configurator;
    • If a new stable version is available online (and you are connected to the internet), a message will prompt you to open the update window.
    • If you are using a beta version and a new beta or stable version is available online, the same message will appear.
    • You can also open the update window manually via:
      Additional Settings > Connected Device Information > Firmware version > Change Firmware.
  • In the update window, select the version you want to install from the dropdown menu.
  • Click the Start button. The file is first transferred to the Vario (blue LED, less than 2 minutes), then installed (purple LED, less than 10 seconds).

Via the micro SD card: :

  • Download an update file from the Update files (manual download) section below;
  • Copy the file (without renaming it) to the root of the microSD card;
  • Insert the card into the powered-off Vector Vario, then turn it on;
  • The update will run automatically (purple LED, less than 10 seconds), then the Vario will power off.
  • Turn the Vector Vario back on and check the installed version to confirm that the update was successful.

Notes:

  • It is possible to install a version older than your current one.
  • Previous versions remain available online as long as they remain compatible with the Configurator.
  • You can also update via BLE while offline by selecting “Other” in the update window, choosing a file from your device, and following the update process.
...

  • Stable version that incorporates and officially validates all modifications made in the beta versions.
  • Improved landing detection.
  • Multi-flight management (successive takeoffs and landings).
  • IGC log accessible via BLE transfer immediately after landing, without having to power off and restart the vario.

Vector Vario v2.00e (27/04/2026) :

  • Improved overall vario accuracy and lower noise.
  • Improved wind calculation.
  • Improved landing detection.
  • Improved GNSS accuracy.
  • Fixed a bug when recording GNSS coordinates in IGC files occurring between 0° and 1°S latitude and 0° and 1°W longitude.
  • Fixed a bug where the Vector Vario did not account for changes to the simulator’s double/triple beep delay when playing sounds from the Configurator.

Vector Vario v1.34c (28/03/2026) :

  • On pro versions, fix a bug concerning GNSS position when turning off CSV log (switching then automatically to an IGC log).

Vector Vario v1.34b (24/03/2026) :

  • Increase in overall autonomy (> +3 hours).
  • Improved estimation of the remaining battery capacity.
  • Enhanced GNSS settings (removal of a delay in position reporting).
  • Improved landing detection.
  • Factor of 10 applied to the experimental ΔTdew indicator on XCTrack to display smaller variations.

Vector Vario v1.33 (11/02/2026) :

  • Validation of the new features introduced in version v1.33b.

Vector Vario v1.33b (12/01/2026) :

  • Improved air temperature responsiveness by compensating for measurement inertia.
  • Added multiple external data fields in XCTrack to display the Vector Vario configuration using the latest version https://dev.xctrack.org/prod-123ed437a5ab336801288139f9e307cc07cf710d-1766158177.apk (please visit the page of applications).
  • Experimental: transmission of the calculated theoretical cloud base altitude to XCTrack.
  • Experimental: transmission of the calculated ΔTd° (dew point temperature variation) to XCTrack to explore its behavior in thermals and within the boundary layer.
  • Added the external command AUTOSHUTOFF=ON to enable automatic vario shutdown after 45 minutes of inactivity.

Vector Vario v1.32 (10/01/2026) :

  • Validation of the new features introduced in version v1.32b.
  • Improved thermal calibration for airspeed measurement.
  • IGC filenames are now based on UTC date and time.

Vector Vario v1.32b (01/12/2025) :

  • Log IGC – Data recording now works as a black-box system, with flight data saved and signed until the very last second, whatever happens to the Vector Vario.
  • Log IGC – Added attitude parameters (heading, roll, and pitch) to the set of data already recorded every second (position, altitude, wind direction and speed, netto, IAS, total G-force, air temperature, and humidity).
  • Algorithm – Correction of the aerodynamic influence of the harness on average airspeed.
  • Algorithm – Experimental! Added support for rigid wings (hang gliders & Swift).
  • System – Added the extra command AIRCRAFT=x to adapt the algorithm to different aircraft (default value x = 0 for paragliding, x = 1 for hang gliding, x = 2 for Swift).
  • System – Added the extra command LED=x to control LED brightness (x between 0 and 100).
  • System – Added the extra command GNSSLED=x to provide feedback on GNSS fix status. With x = BI (default), the LED switches instantly between red and green to indicate the current fix status. With x = TRI, an additional orange color is used to indicate between 1 and 28 fixes during the last 30 seconds. In other words, orange means the GNSS fix is valid, but waiting for green is recommended if your flight validation requires 20 seconds of fix before takeoff. In flight, orange may also indicate rare situations where GNSS fix quality is degraded, which may affect the algorithm.
  • System – Added the extra command BLECHECK=x to enable (x = ON, default) or disable (x = OFF) the 4 clicks required for BLE connection. Note that without this confirmation, someone could connect to your powered-on Vector Vario and modify its settings without you noticing.
  • Pro Version – Added a fast triple beep (after the startup beeps) to confirm that Log Pro has started correctly.
  • LED color during clicks is now white instead of yellow, to clearly distinguish it from the orange now used for GNSS reception.
  • Long-press duration for powering the Vector Vario on/off is reduced to 2 seconds.
  • XCtrack – possibilité d’afficher les valeurs de roulis et tangage dans les Données Externes 5 et 6 en utilisant la release https://dev.xctrack.org/prod-3536115dc81d0c50799de7a39c490895d153b37a-1764308789.apk
