Parameters

The crazyflie’s parameters are directly mapped and connected to the corresponding ROS2 parameters.

Get a list of all parameters by writing:

ros2 param list /cf0

in the terminal. What each parameter does can be found on the official bitcraze documentation.

Note

The parameters are not initialized when a crazyflie is connected, as this would require to poll hundrets of parameters. Therefore ros2 param get .. will not work until a parameter is set. To find out the default value of the parameter use the crazyflie client or investigate the source code.

For setting parameters you can use the following command:

ros2 param set /cf0 <parameter_name> <value>

this will not only set the node’s parameter but also update the parameter on the crazyflie.

Note

For the webots simulation there is no parameter server implemented yet. Therefore when using webots crazyflies parameters cannot be set or get.
