Getting Bluetooth LMP version via Powershell - powershell

Question

I have taken a look at CIM_NetworkAdapter, Get-NetAdapterAdvancedProperty CIM_LogicalDevice, Win32_PnPDevice and more.
How can I go about grabbing the LMP version of a Bluetooth adapter from its "Bluetooth Radio Information" in its advanced properties?
Is this possible in Regedit -or any other way?
EDIT,
ANSWER:
Here's a modified version of an answer I received on Reddit from u/ChaosTheoryRules
$BTDevices = Get-PnpDevice -Class "Bluetooth"
Foreach ($device in $BTDevices) {
$BTDeviceProperty = Get-PnpDeviceProperty -KeyName "DEVPKEY_Bluetooth_RadioLmpVersion" -InstanceId $device.InstanceID
If ($BTDeviceProperty -And $BtDeviceProperty.Data) {
$bluetoothVersion = Switch ($BTDeviceProperty.Data) {
0 { '1.0b' }
1 { '1.1' }
2 { '1.2' }
3 { '2.0 + EDR' }
4 { '2.1 + EDR' }
5 { '3.0 + HS' }
6 { '4.0' }
7 { '4.1' }
8 { '4.2' }
9 { '5.0'}
10 { '5.1' }
11 { '5.2' }
default { "UKNOWN" }
}
}
}
Write-Host $bluetoothVersion

I don't have the equipment to test, so I can only provide some reference documentation.
You can use BluetoothGetRadioInfo and the structure BLUETOOTH_RADIO_INFO to get relevant information lmpSubversion.

hbf=BluetoothFindFirstRadio(&btfrp, &hbr);
