Problem running the motion flying example with the default crazyflie2.1

[noah2021]

Hi all,
I meet a similar problem illustrated in this post: viewtopic.php?t=3989.

I'm programming according to this tutorial: https://www.bitcraze.io/documentation/r ... commander/
I tried to make the crazyflie fly to 0.3m (Step 2), but it just stayed on the ground, and sometimes the propeller p4 stopped earlier than the other three motors. I'm using the default crazyflie 2.1 and no flow-deck or any other deck is used at this moment.

It's ok to use my Android app to make it fly, and it seems the thrust is not enough if I use the script.

Can anyone help me with that? Thank you.

The autonomous flights need some form of positioning system like the flow deck. The internal sensors are not enough.
