I work for a library system that owns ten CrazyFlie 2.0s and ten CrazyRadio PAs. The quadcopters all work great, and nine of the CrazyRadios do, too. But the last radio dongle shows that it can see the CrazyFlie I am trying to connect to, but when I try to actually connect to it I get:

ERROR:cflib.crazyflie:Couldn't load link driver: Cannot find a Crazyradio Dongle

If I plug in a different dongle it connects and flies just fine, so it's definitely the radio that's the issue here. I tried to flash it with a new firmware, but in the first step when I try to switch it into bootloader mode, I get "Error! bootloader not started". I don't know where to go from here. Any suggestions?

Hi,

What operating system are you using? If linux it would be useful to see the output of 'dmesg' when connecting the Crazyradio.

Windows 10, unfortunately. I've got Cygwin installed, but I've never tried using the Crazyradio from there.

Can you see the dongle in the device manager? If so could you PM the serial number to me?

To get the serial number you can follow this documentation (it is written for Crazyflie but the procedure is similar for Crazyradio): https://wiki.bitcraze.io/projects:crazy ... al#windows
