Issue with Windows Bluetooth Device Enumeration #860

KumarShankar92 · 2023-10-19T14:27:50Z

Description:
I am encountering an issue with my Windows application where it is not providing accurate information about connected Bluetooth devices. Even when there is only one connected device, the application is listing numerous devices, and the "connected" field is empty.

Here are some key details about the problem:

Operating System: Windows 10
Bluetooth Device Enumeration: The application is displaying a long list of devices, including "Bluetooth LE Generic Attribute Service," "T2 Avrcp Transport," "Intel(R) Wireless Bluetooth(R)," and others, even when there is only one connected device. The "connected" field is not providing the correct information.
output:
[
{
device: null,
name: 'Bluetooth LE Generic Attribute Service',
manufacturer: 'Microsoft',
macDevice: null,
macHost: null,
batteryPercent: null,
type: '',

@KumarShankar92 can you run the following code in Powershell and post the output here?

Get-CimInstance Win32_PNPEntity | select PNPClass, Name, Manufacturer | fl

The data systeminformation gets should be exactly what you see in this command.

Btw: connected: null means (like all null values in systeminformation) that we have no information about that. Thank you in advance.
