Hi,
This is likely caused by your Crazyflie not being setup on channel 80 datarate 2M as configured in the script by the uri "radio://0/80/2M".

You can find your current Crazyflie radio parameters by connecting it with the Crazyflie client, the URI will be shown in the client. The connection parameter can be changes in the client in the menu "connect/configure 2.x", it is advised to at least set the datarate to 2M to improve radio performance.
