Why is my BLE Notification callback never called on Windows 8

I have a Bluetooth LE device with customizable specifications that send notifications to an Android device very accurately.

However, notifications are not accepted in Windows 8.1. I can open a connection to a device with CreateFile()

, turn on alerts with, BluetoothGattSetDEscriptorValue()

and register a callback function with no problem BluetoothGattRegisterEvent()

. However, the callback function used is never called unless I permanently set the "Values" value manually to keep the connection live using something like this:

while(1){
    Sleep(1000);

    // Write characteristic using BLuetoothGattSetCharacteristicValue()
}

      

        
        
        
      

    

Should it work like this? How can I call a callback when notifications are activated without having to manually initiate a connection?
