!IMPORTANT!

If the tool reports that it is "Working" for more than 30 seconds, then please plug it back into the vehicle and the original issue should be resolved without further action.

Preface

Clear voice capture is a Qualcomm-owned proprietary algorithm that cancels echo and noise picked up by the microphone in the vehicle. If your BlueBus did not come with the cVc license installed, or you want to make sure it is enabled, then this tool is for you.

It is avaiable for Windows (64-bit only, so no XP), macOS (64-Bit -- Requires macOS 10.15 or newer), and Linux.

macOS / Linux First Run

If this is the first time you're running the firmware tool on macOS or Linux, you will need to use the Terminal app to run the the follow command:

macOS

 chmod +x ~/Downloads/BlueBus_CVC_Tool_macos

Linux

 chmod +x ~/Downloads/BlueBus_CVC_Tool_linux

Install Process

First, plug the BlueBus into your machine and open the Clear Voice Capture tool.

Let the tool load up and then select the BlueBus COM port / device path from the selection dropdown. If you have multiple options, unplug the BlueBus and refresh the list, the one that is no longer there will be the one to select once you plug the BlueBus back in.

Select Device

Let the tool report the serial number of the unit, then click "Apply cVc"

Apply

Once the tool reports Successfully Applied License!, you are done!

Great Success

Troubleshooting

The tool reported an error

Try again or contact support@bluebus.dev if the issue persists.

If you're not seeing any options when you click "Select Device..." or if the option you have returns a "Timeout" error, please try the troubleshooting steps below.

macOS

  1. Try another cable. Many USB Micro-B cables are "Charge only", meaning that the data lines are missing, making it useless for data communcation.

  2. If your BlueBus has Phillips screws on top, slightly loosen them off so you can better seat the USB cable.

Windows

  1. Try another cable. Many USB Micro-B cables are "Charge only", meaning that the data lines are missing, making it useless for data communcation.

  2. If your BlueBus has Phillips screws on top, slightly loosen them off so you can better seat the USB cable.

  3. Check the Device Manager

    1. Windows 10: Right Click Start > Device Manager
    2. All other versions: Hold the "Windows Key" on the keyboard then hit r. In the box that pops up, enter devmgmt.msc and hit enter
    3. Disconnect the BlueBus and reconnect it. If the screen DOES NOT refresh itself, then there is an issue with the USB cable.
    4. If the screen does refresh, look for any entry that might say FT232R or USB Serial Converter. If you see either of these entries, you need to download and install the drivers. I recommend the "setup executable" linked for Windows.
    5. After installing the drivers, reboot and try again.
