Hi there,

Our Crazyflie suddenly stopped working and now we can't seem to fly at all. I don't believe it was dropped or otherwise mishandled but we are unable to fly it at all right now. For reference, we are running the crazyflie virtual machine on a PC and a PS3 controller is connected thru one of the USB ports.

However, I believe the problem is in the Crazyflie itself. When we turn it on, all the lights flash briefly and then the blue light stays on. None of the motors spin at all. When we try to connect to the quadcopter at this point, we are never able to establish a connection.

Would really appreciate some fast help on this,

Hi,

So none of the motors spin during the start-up self-test? Did you try to update the firmware at some point? It sounds like this might be the case. Try to re-flash the firmware using the bootloader and see it it helps.
