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. The image version 2015.3 is based on Raspbian version 2015-02-16 available on the RaspberryPi website.

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 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 (version 2015.3 and onward is compatible with Raspberrypi 2):

• Bitcraze Raspbian image 2015.3 (torrent) (direct download) (mega)
• Bitcraze Raspbian image 0.3 (torrent) (direct download)
• Bitcraze Raspbian image 0.2 (torrent) (mega)
• Bitcraze Raspbian image 0.1 (torrent) (mega)

If you already have a running raspbian system no need to download the image, connect your raspberrypi and run the following command to install all packages and dependencies. We are generating the official that way. You must be logged with the 'pi' user to launch the command:

curl https://raw.githubusercontent.com/bitcraze/bitcraze-raspberry-pi/2015.3/bitcraze_raspberrypi.sh | sh

Size: 4 GB
User: pi
Pass: raspberry

(version before 2015.3 had bitcraze/crazyflie as username/password)

There's a list of what's added:

• UDEV rules for access to the Crazyradio and NRF bootloader
• crazyflie-pc-client pre-cloned at latest stable version
• pyusb
• 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

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/pi 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 should be ready to fly.

To quit 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.

Check logfile /tmp/cfheadless.log for messages

You will have to edit the /root/bin/xbox file to contain the following to get the RedOctaine xbox360 (1430:f801) controller to work:

#!/bin/sh
if test "$ACTION" = "add"
then
/usr/bin/xboxdrv --device-by-id 1430:f801 --type xbox360 --axismap X2=X1,Y2=Y1,X1=X2,Y1=Y2 &
else
killall -9 xboxdrv
fi
