Hi guys,

Can i use Crazyradio dongle as COM port to PC ?

According to wiki's install guide of Crazyradio, computer recognizes the dongle as "libusb-win32 devices".

I want to make MFC program to communicate with Crazyflie instead of using conventional Crazyflie PC client. And when dongle is connected as COM port, i think it's easier to manage communication.


I desperately need your advices. Thank you.

Hi,

Quick answer is no, you can use MFC but then you have to talk to the dongle with LibUSB or WinUSB, two libs that allows to talk to the USB device directly. This is not that hard and the protocol is documented on our wiki.

Having the dongle seen as a serial port is possible but you would have to program it. That is even more complex as it require to program the dongle 8051 microcontroller and serial port over usb is not super easy to get working correctly.

Tell me if you need help understanding the USB protocol. With the right lib re-implementing a simple driver should be quite quick.

Regards.
