Hi!

Have you looked at the reboot script in the crazyflie-firmware repo? That is doing exactly what you need.

Probably you have installed an older version of the cflib. Could you check that with:

Code: Select all

pip freeze | grep cflib
And show the output here.

Also, which firmware version are you using on your crazyflie?

your cflib seems to be after this reboot functionality has been implemented....

So I tried it with firmware 2019.01 and cflib version 0.1.11 (which is the last version feature will work on). It works fine for me.

Could you reinstall the cflib to the latest release?:

Code: Select all

pip3 install cflib==0.1.12.1
and then please try again. Also make sure that radio://0/10/2M/E7E7E7E710 is indeedd the right address for your crazyflie.
