Firmware Updates

advanced

Overview

WVC units support over-the-air (OTA) firmware updates for both the base station and the wireless knob via the LF Audio AuralSync app. Updates deliver new features, signal analysis improvements, and bug fixes. Both Wi-Fi and Bluetooth update paths are supported.

Checking for Updates

  1. Open the LF Audio AuralSync app and connect to your unit.
  2. Tap on the device tile to open its detail view.
  3. If an update is available, an orange notification banner will appear at the top of the screen showing the current and new firmware versions, along with release notes. You can also verify your current firmware version at any time:
  • On the knob: Hold the top button → Device Info → Hardware Info
  • In the app: Open the device → firmware version is listed in the device info section

Setting Up Wi-Fi (Required for OTA Updates)

Wi-Fi credentials must be entered in the app before performing OTA updates. You only need to do this once per unit.

  1. In the AuralSync app, open your device settings.
  2. Enter your Wi-Fi SSID and password in the Wi-Fi fields.
  3. Tap Save / Confirm.

    The unit connects to 2.4 GHz Wi-Fi only. If you do not have a 2.4 GHz network nearby, you can temporarily enable a Wi-Fi hotspot on your phone and use those credentials.

Updating the Base Station

  1. In the AuralSync app, tap the firmware update notification on your device.
  2. Select Install via Wi-Fi.
  3. The unit will connect to your Wi-Fi network and begin downloading the update.
  4. A progress indicator and ETA timer are shown both in the app and on the unit's display.
  5. Once complete, the unit automatically restarts. No manual action is required.
  6. After restart, re-open the device in the app to confirm the new firmware version.
    Note

    The WVC-PRO has two CPUs (primary and secondary). Both are updated automatically in a single OTA process — the primary CPU updates first, then pushes the update to the secondary. The WVC-PRO 6-Channel has a third CPU (daughtercard) that is also updated automatically.

Updating the Wireless Knob

The knob receives its firmware update through the base station's WiFi connection:

  1. In the AuralSync app, tap the knob firmware update notification.
  2. The base station shares its WiFi credentials with the knob wirelessly.
  3. The knob connects to WiFi and downloads the update directly.
  4. Progress is shown on the knob display.
  5. Once complete, the knob restarts automatically.
Note

The knob must be connected to a base station with valid WiFi credentials to receive updates. If you have an RTC, it can also update independently using saved WiFi networks.
