Bitcraze Forums

I am a newbie to use drones for development. I followed all the instructions given on the Bitcraze website. First, I tried to use by connecting Crazyflie PA USB Dongle to Computer in Bitcraze VM. It always shows sate captured but when I try to connect, the following error:

Failed to attach the USB device Bitcraze Crazyradio PA USB Dongle [0053] to the virtual machine BitcrazeVM.

USB device 'Bitcraze Crazyradio PA USB Dongle' with UUID {6856186c-b132-4375-b020-43d5fe2a39e2} is busy with a previous request. Please try again later.

When I download cfclient software available for Windows, I updated the firmware. Now, when I tried to connect it again in BitcrazeVM, it is not shown. After the firmware update, only two blue LEDs M2 and M3 are ON. If I try to connect it with mobile for flying, it does not connect. If I press power button for a long time, only one blue LED start blinking.

What should I do to solve issues with BitcrazeVM and also why the Crazyflie 2.0 is not being controlled by firmware update.

I am using windows 10. To run cflient software, I run it in compatibility mode.

Any help in this regard is appreciated.

It looks like the client is working fine on Windows, but the flashing might have failed for some reason. If you re-program your Crazyflie, it should boot again.

One note: make sure you are choosing the ZIP file when updating the Crazyflie, the full zip is used, you should not extract it first.
