+ | |||
+ | -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)/ | ||

If you need any additional setup to get your controller working, you can add a similar udev-rule for that to take care of everything upon plugging in the controller as well. | ||
:!: **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. | :!: **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.

+ | ...your controller may very well have already started automatically per the udev rule you created above and could be working correctly and currently is in use. Make sure your wireless xbox controller is powered on and connected (green arc showing), turn on your crazyflie and then plug in your crazyradio. | ||
