In order to make it easy for users that have a Raspberry Pi to test out our headless client we prepared an SD-card image that is ready to use out of the box. The image is based on the Raspbian distribution, more specifically the Wheezey version that can be downloaded from this torrent.

We haven't removed anything from the image, just added our own stuff. So you can still log in and used the Raspberry Pi as you would with the Raspbian Wheezy image, but as an added feature you can also use our stuff. If you would like to re-create the SD-image with your own Wheezy image then have a look at what we did.

The changes made to the SD-card is mostly based of the contributed instructions from the hacks section.

The SD-card image can be downloaded here:

• Bitcraze Raspian image 0.1 torrent (preferred)
• Bitcraze Raspian image 0.1 direct download (limited to 6 simultaneous downloads)

Size: 2 GB
User: bitcraze
Pass: crazyflie

There's a list of what's added:

• UDEV rules for access to the Crazyradio and NRF bootloader
• crazyflie-pc-client and crazyradio-firmware pre-cloned
• pyusb and pygame
• UDEV rules to automatically launch the cfheadless client when Crazyradio is plugged in
• Driver for the Xbox 360 wireless controller and automatic start of the utilities
• Mercurial

First of all you have to write the image to the SD-card. There are good instructions on how to do this here.

First of all you need to set up what controller and link settings you are using. This is done by editing the two files in the folder /home/bitcraze named controller.conf and link.conf. They should only contain one row each.

To fly first insert the USB controller, then power on the Crazyflie and lastly insert the Crazyradio. This will start the cfheadless client and connect to the Crazyflie. In a few seconds you sould be ready to fly.

To quick either power off the Crazyflie or pull-out the Crazyradio.

In order to restart flying you have to pull-out the Crazyradio dongle and insert it again.

Try to pull-out and insert the Crazyradio. Then wait up to 10 seconds before you try to control the Crazyflie.

If you see the LED on the Crazyradio blinking green, then it's connected. If it's blinking red it means that it cannot connect to the Crazyflie.
