CoreBluetooth cannot discover Windows computers

I am working on a project that involves Bluetooth. I tried to use CoreBluetooth for that but it couldn't discover both of my Windows devices. Interestingly, using IOBluetooth to scan for devices, can discover the Windows computer. However, I want to use one consistent code base for my project and sending data over to another device using bluetooth without pairing(RFCOMM and L2CAP both require pairing).
