I'm unable to connect to INAV

If you can't connect the RubiQ drone to INAV, you may have the incorrect version or drivers installed.

This article applies to RubiQ 1.0, RubiQ 1.5 and RubiQ 2.0 (Taranis Q X7).

For help connecting RubiQ 2.0 (Taranis X9 Lite) to the RubiQ Configurator, click here.

If you have trouble connecting to INAV:

Look in the top left corner to make sure you have downloaded the correct version.

  • Early RubiQ’s with the vertical red and black bullet motor connectors are only compatible with version 1.6.2.
  • More recent RubiQ’s with the horizontal yellow motor connectors will only work with version 1.9.3.

Both versions must be downloaded directly from rubiq.edventures.com. If INAV is downloaded directly from the Google Chrome store, it will eventually become incompatible with RubiQ’s firmware as it auto-updates.

If you still have trouble connecting to INAV:

Check to make sure the port dropbox in the top right is set to the correct option.

The exact name of the port depends on the computer being used. Common names include USBtoUART and COM3. Click the Connect button to restart the connection process.

If your computer is not recognizing your board:

Download the VCP drivers directly from the following links:

  • Download: Windows 7-current
    • Right-click the file and select extract all. This will bring up a sub-menu asking you to select a destination for the extracted files.
    • Press the extract option at the bottom. From there a new file window will appear containing multiple files.
      • Select the application file called CP210xVCPInstaller_x86 for 32-bit operating systems.
      • Select the application file called CP210xVCPInstaller_x64 for 64-bit operating systems.
    • Proceed through the onscreen prompts and various windows until the installation is complete.

To determine if your PC is 32- or 64-bit, open your Control Panel > System > and look for the line item System Type. This will dictate if you are using a 32 or 64-bit OS.

  • Download: Mac
    • Double-click the file to begin unzipping the file. A new .DMG file will appear.
    • Double-click the .DMG file to begin the installation process.
    • Proceed through the onscreen prompts until the installation is complete.

Once you’ve downloaded, unzipped and installed the driver, restart INAV and unplug and plug RubiQ back into the computer.

The VCP driver facilitates the connection between RubiQ and your computer’s ports. It should auto-select the correct port once it has been downloaded.

If you have downloaded the drivers and still cannot connect:

Try a different USB cable. RubiQ needs a data USB cable to connect to INAV. Some USB cables are charging-only. These cables deliver only power and are not able to establish a connection between RubiQ’s flight controller and the INAV configurator.

If you are still unable to connect:

Please attempt a manual port selection.

  • Click on the drop-down menu in the upper right of INAV and sekect the Manual Selection option. A new box will appear to the left that begins with Port:.
  • Enter /dev/tty.SLAB_USBtoUART.
  • Unplug and plug RubiQ back into the computer.
  • Click Connect in the upper right.
