and I saw that crazyfiles 2.0 can read parameters and easily logg data using PC client like below capture image.

but, I can't connect notebook PC supproted by bluetooth 4.0+ with crazyflie 2.0.
Anything cannot be shown in scanned list... even I have used VM, Bitcraze VM 0.6...
Bluetooth Carzyfile have "드라이버 오류" means to "driver error" like below caputre image.

How can I connect PC client with my crazyflie 2.0 and logg data?
Is it nessesary to buy the Crayradio 2.4GHz radio USB dongle?
