[SOLVED] Problem with the Crazyflie

[Liveunderwater]

Yes, now I get the same error in the console everytime I connect.

@liveunderwarter
I interpret it that you are able to find the Crazyflie when you press connect button e.g. "radio://0/10/250k" turns up? And when you try to connect to it you get the error in the console?
It looks like some firmware and cf-client incompatibility but the strange thing is that you can't connect to the bootloader which you managed before? That makes me think there is a HW problem so try pressing on the radio chip (the chip located closest to the blue antenna) when connecting. It might be a bad solder or crack in the solder on the radio chip.

Here is the Output from the Console when the Fly connects.

Code: Select all

SYS: Crazyflie is up and running!

Sorry, I was a bit unclear. Could you paste the text from the windows terminal that the application launches in instead?

Great, thanks.

Could you paste the text from the windows terminal when you try to update the firmware? Just click Initate cold boot and power on the Crazyflie.

This is very strange.

It indicates that it managed to connect to the bootloader but doesn't get the right information back. Since there been no changes to the bootloader I don't see how this could happen...

[tobias]

KOschi, do you have access to any other operating system or maybe other computer? It might be an issue with the VMware usb backend so we would like to take that out of the picture.

[KOschi]

yeah i can try my desktop computer when i am home. Im posting my results then.
