Connecting to Crazyflie

The Crazyflie uses a 2.4 GHz radio to communicate. There is a USB dongle called the Crazyradio that is required to control the Crazyflie quadcopter.

If you are have a USB 3.0 port, you might run into this issue

Crazyflie Hover

To use the Crazyflie beta 'hover' mode, you will need to install the latest beta of firmware to the Crazyflie itself from

Once you have updated the Crazyflie firmware, to trigger the hover mode on, use the flightmode.althold param on the Crazyflie like this:

  @crazyflie.param.set_value('flightmode.althold', true)

Please note that the Crazyflie's interprets hover to mean "maintain altitude", not "stay in one place", so you will need to control horizontal positioning yourself.

To turn hover mode off:

  @crazyflie.param.set_value('flightmode.althold', false)

Once you turn hover mode off, the Crazyflie requires that you immediately apply thrust, or it will just drop like an unpowered PCB from the air. You have been warned...


Check out our documentation for lots of information about how to use Artoo.
