- | This installs the necessary dependencies for running the client, checks out the current development version from BitBucket and then switches to the branch containing the headless client. | ||

- | **Note**: If you used a Windows 7 PC and the cfclient GUI to create a customized .json file for your xbox controller and plan to copy it over to your Raspberry Pi here is some advice: | ||
- | |||
- | -save the new .json file as something different than the default, so you can recognize it easily. | ||
- | |||
- | -the new .json file is not located in the Program Files(x64)/ | ||
- | |||
- | -copy your new .json file into the correct RPi folder: / | ||
- | |||
- | -the cfheadless client on RPi may not recognize the same controller channel " | ||
- | |||
- | |||
- | **Note**: If you have more than one controller attached, you can select the one to use using the commandline parameter '' | ||

- | usage: cfheadless [-h] [-u URI] [-i INPUT] [-d] [-c CONTROLLER] | ||
- | [--controllers] | ||
- | |||
- | optional arguments: | ||
- | -h, --help | ||
- | -u URI, --uri URI URI to use for connection to the Crazyradio dongle, | ||
- | defaults to radio:// | ||
- | -i INPUT, --input INPUT | ||
- | Input mapping to use for the controller, defaults to | ||

- | -d, --debug | ||
- | -c CONTROLLER, --controller CONTROLLER | ||
- | Use controller with specified id, id defaults to 0 | ||
- | --controllers | ||
- | </ | ||
- | |||
- | **Note**: If you still have an old version of the headless client you'll need to manually change the URI of your Crazyradio from the default 1M to 250K (make sure the K is uppercase). If you want to use a custom configuration (other than '' | ||
- | |||
- | <code python> | ||

- | ===== Make the client startup automatically on Crazyradio plug in ===== | ||

- | Adjust your Crazyradio udev rule (e.g. ''/ | ||

- | :!: **Important** :!: Due to the current state of the client, you **must** make sure to first connect your controller and power up the Crazyflie before connecting the Crazyradio dongle and thus starting the client. If the client can't find either controller or Crazyflie, it will just hang and you'll have to re-plug the dongle again. | ||

- | Also, if xboxdrv can't be run without the sudo command, or there are other permissions issues with the xbox wireless usb controller, try adding the the xbox360 wireless receiver to a group that has root privileges. | ||

- | ===== Make your base station portable ===== | ||
- | |||
- | If you want to you can make your base station completely portable simply by using a portable USB power supply (e.g. the Anker3 10.000mAh) for powering the Pi. Putting everything into some case and attaching it somewhere on yourself (e.g. your belt) makes you completely mobile while piloting your Crazyflie :-) | ||
