While SoundCheck’s built-in Bluetooth message steps address the majority of use cases, there are some additional controls for specific applications, such as ‘man-in-the-middle’ connection or controlling AVRCP volume. You can access these from the command line. Let’s take a look.

If you haven’t already installed the driver for your bluetooth device, you’ll need to do this first. Make sure you select the correct driver for your device. I already have my driver located here on my local C-drive.

I am using a BTC4148A, so I will use the command name “btcutil”. This name depends on your device so check the documentation for your device to make sure you are using the appropriate name. 

Copy the file path, and now  let’s run it from the command line. 

To view the current settings, you can either use the command “–list” or “/l”.

A list of available commands is in the documentation, or you can use the command “–help” or “/?”. These are all the commands available to use with the device.

Now let’s enable  “Man in the Middle” using the command line utility. If we check the current status, we can see it’s set to zero, or off. Now I’ll switch it on using the command “/mm ON” and if we go back and check the settings again, you can see that it’s now set to 1 which means this function is now enabled.

Another useful tool is controlling the AVRCP volume. This lets us control the volume of a paired bluetooth speaker.

I’ll use the query command for the interface to scan for bluetooth devices. And I’ll set it to run for 5 seconds. 

The interface has discovered my Bluetooth speaker so I’ll copy the Bluetooth address and pair it. 

Now you can see it is paired, and we can change the AVRCP volume using the command “/av” and setting the volume between zero and 15, let’s set it to 10.

And, if we check the configuration, you can see the AVRCP volume is now set to 10.

So that’s how you can gain control over additional Bluetooth functionality through the command line. Give it a go, and contact Listen support if you need any additional help.
