Crazyradio PA not picking up Crazyflie 2

[accentronix]

I have a crazyflie 2 which works perfectly with my android device via bluetooth but I can not connect it the crazyflie to my pc via the Crazyradio PA. The Crazyradio PA drivers is installed but when I open the pc bitcrazy client and click on 'Connect' it does not pick up anything. When I click on 'Scan' it still does not pick up anything.

I am using a windows machine.

Is there an easy way to upgrade the Crazyradio PA firmware instead of by using python?

Which Windows version do you use?

What problems do you have with flashing the Crazyradio firmware using Python?
