[SOLVED] a question about Crazyflie2.0 take off

Dear All:
I am sorry to bother you ! After running a python sample code Flow_Deck.py, Crazyflie2.0 doesn't take off and it just stay on the ground, I am not sure what is the reason behind this. Could you give me some suggestions on how to fix such problem?
I have checked my crazyflie2.0 environment configuration and setting parameters in Ubuntu16.04, there are no problems related to hardware and software installation, however, the crazyflie2.0 could not take off.
Best Regards

Hi,
After the discussion you have had by mail with Kimberly, it seems that your flow deck is not detected by the Crazyflie since its identification memory is not programmed.
The quickest way to solve this problem would be to program the memory yourself, since you seem to have a python development environment working it should be quite easy.
I attach to this post a version of the firmware that disables BLE (this is required to program the deck memory). You should flash it using the client as described in the getting started guide.
Then you can run the python file I also attach to this post, if it works out you should see an input similar to:
Code: Select all
$ python3 write-ow-flow2.py
This example will not work with the BLE version of the nRF51 firmware (flashed on production units). See https://github.com/bitcraze/crazyflie-clients-python/issues/166

Dear Dr. arnaud:
I am really thanking for you big help! After following your good codes and instructions, my crazyflie2.0 can take off and fly with flow deck.
