Autonomous Flight using NavData

[tkasidakis]

Hello to everyone.
I would like to run an autonomous flight for the parrot drone using navdata.

For example i would like to take off at a specific altitude but instead of using time.sleep() i would like to continuously checking the altitude and break when the desired altitude reached.

root@ubuntu:/home/ubuntu# python3 parrot.py
Traceback (most recent call last):
File "parrot.py", line 8, in
print(parrot_drone.navdata.demo)
AttributeError: 'NavData' object has no attribute 'demo'

I am receiving this.

Am i doing something wrong with the navdata.

I fully undertand the docs but it seems that the code doesn't understands me.
