Windows test if BLE device is currenlty connected using SetupAPI in C

Question

I'm trying to discover if a Bluetooth Low Energy (BLE) device, that has been paired previously, is currently enabled using setupAPI in a C program with minGW compiler. At the moment I'm trying to use setupAPI SetupDiGetDevicePropertyW() function for property DEVPKEY_Device_IsPresent but the result is always true even if the BLE device is currently switched off. The property DEVPKEY_DeviceContainer_IsConnected produces an error code 1168. Does anyone have done something similar already?

The relevant console output for my device:

SPDRP_FRIENDLYNAME: Testdevice
The device is present.
Failed to get connn property: 1168
Failed to get paired property: 1168

The output has been generated by the following test c program.

#include <Windows.h>
#include <Setupapi.h>
#include <initguid.h>
#include <devpkey.h>
#include <devguid.h>

        if (hDevInfo == INVALID_HANDLE_VALUE)
