Re: Upgrade via bluetooth failed and now is dead

Hi,

Is there only one blue LED blinking, or two? If you enter bootloader mode then both of the blue LEDs should blink.

Here's a Vine showing what it should look like. If you hold the button for too long only one LED will blink and the STM32 will go into DFU mode, which is not what you want.

Re: cfclient segmentation fault [SOLVED (workaround)]

Thanks for the info. It's strange that the Crazyradio works though. As far as I can see the code for finding the device is the same.

Could you try starting the client with and without the Crazyradio? Just to check if there's an issue when the device isn't found.

Re: cfclient segmentation fault

Hi, There's two things that comes to mind: Mixing 32bit and 64bit libraries: Check that you consistently have the same version (i.e if Python3 is 32bit then the dependencies should be as well) Issue with libusb/pyusb: There's a few different versions of these and the API changes between them. What v...

Re: Maker Faire Berlin Bitcraze meet-up

It's been a stressful day so we're a bit late on this. But after getting some recommendations at the fair we decided to join in on the Hackaday/VCF meetup here. We'll be hanging around wearing Bitcraze.io t-shirts so you can't miss us.

Re: Maker Faire Berlin Bitcraze meet-up

Great! We will meet up somewhere outside the fair, probably at a bar nearby :) Is it easy to get to Meltdown from Ostbahnhof?

Re: Control with UDP

Glad to hear that it's working. It would be great if you wanted to share your Matlab solution for ZMQ.

Re: Vicon Control of CF 2.0

Hi, Maybe you need to change the sign of one of the axis in your calculations. If you place the Crazyflie infront of you with the blue LED's closest to you and the front facing away (like in in this image ) the changes in axes are as follows: Roll is positive to the right Pitch is positive backwards...

Re: Crazyflie 2 with i2c Camera

Hi,

I think it's worth a try. The link is 2Mbit, in theory. But the bandwidth is lowered by re-sending and overhead. we don't have an exact number but the master thesis that Fred mentioned have test values for it. But you will not get 30 fps.

Re: crazy Flie sensor values are drunk! It's tilted 90 degrees

Hi,

Do you still have this issue? If so then could you flash the attached firmware and past the console output from the Crazyflie?
