How to? Any way to display the battery status of my bluetooth devices?

[K_Meinhard]

Hi ,

I'm looking for a way to display the battery status of my bluetooth devices. I see no obvious candidate among the bluetooth functions or BTMonitor. Any tips?

No, the bluetooth library doesn't have an option to return that information.

BTW. when I do a echo %@btradioclass[0], I get this dialogue:

Something issue at my end?

Somewhere Windows has that information. It is shown in the Bluetooth Device panel in my tray under Show Bluetooth Network Devices. Any Idea what's the relevant function library?

No, same here.

A search on GitHub returned a couple of interest...

Here is a Powershell Script that says it will show Bluetooth Device Battery Level...

This Powershell Script shows me the battery remaining on my Bluetooth speaker...

Get-PnpDevice -FriendlyName "*Tribit XSound Go*" | ForEach-Object {
    $local:test = $_ |
    Get-PnpDeviceProperty -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' |
        Where Type -ne Empty;
    if ($test) {
        "To query battery for $($_.FriendlyName), run the following:"
        "    Get-PnpDeviceProperty -InstanceId '$($test.InstanceId)' -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' | % Data"
        ""
        "The result will look like this:";
        Get-PnpDeviceProperty -InstanceId $($test.InstanceId) -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' | % Data
    }
}

After running...

R:\>pshell r:\test.ps1
To query battery for Tribit XSound Go Hands-Free AG, run the following:
    Get-PnpDeviceProperty -InstanceId 'BTHENUM\{0000111E-0000-1000-8000-00805F9B34FB}_LOCALMFG&000F\8&495D9F9&0&F44EFD00C255_C00000000' -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' | % Data

The result will look like this:
80

It returns the same result as the Windows 10 GUI...

Thanks to all. I'll wade through the material...

I've found a working powershell command (all 1 line):

Get-PnpDevice -FriendlyName 'cherry' | Select-Object Class,FriendlyName,@{L="Battery";E={(Get-PnpDeviceProperty -DeviceID $_.PNPDeviceID -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2').Data}}

You'll have to know the "FriendlyName" of your BT device. When in doubt, try the manufacterer. It would ne nice to have that available in TCMD, too.

This worked for me under TCC:

Get-PnpDevice -Class 'Bluetooth' | ForEach-Object {
    $local:test = $_ |
    Get-PnpDeviceProperty -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' |
        Where Type -ne Empty;
    if ($test) {
        "Battery percentage of $($_.FriendlyName) is: ";
        Get-PnpDeviceProperty -InstanceId $($test.InstanceId) -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' | % Data
    }
}

 

[K_Meinhard]

Yes. that writes out the battery level of all attached BT devices. The one I cited gives you only those selected by FriendlyName.
