Simulator and USB Dongle

I am working on an App that connects to a BLE service running on a raspberry pie. Right now I am side loading the App all the time for testing. I was wondering if the simulator can use a common usb dongle to communicate with such a service or if it only works with the nRF52 DK as described in

In case a common USB dongle does not work, do you need the hole nordic development kit or is a specific dongle from nordic enough?
