I've created this simple tello code:
from djitellopy import Tello
tello = Tello()
tello.connect()
tello.takeoff()
tello.move_left(100)
tello.rotate_clockwise(90)
tello.move_forward(100)
tello.land()
However, every time I try to run the code, the drone light is yellow, even when I've connected to its wifi and I get this error:
Exception: Command 'command' was unsuccessful for 4 tries. Latest response: 'command'
I had the same problem.
Then I connected the app and there was a need to activate the drone through the app. After that, I could connect the PC to the drone and take off / land.
