Problems with some examples

[Helge543]

Hey,

I'm totally new to DJITelloPy or drones in general. Right now I'm trying to do some of the examples which are provided to start. More specifically, I tried manual-control-pygame.py and simple.py.

When I used to try simple.py I wrote a main function like this:

from djitellopy import Tello

def main():
    tello = Tello()

    tello.connect()
    tello.takeoff()

    tello.move_left(5)
    tello.rotate_clockwise(90)
    tello.move_forward(5)

    tello.land()

if __name__ == '__main__':
    main()

but when I tried to run the program I got the following error message:

[INFO] tello.py - 107 - Tello instance was initialized. Host: '192.168.10.1'. Port: '8889'.
[INFO] tello.py - 422 - Send command: 'command'
[INFO] tello.py - 446 - Response command: 'ok'
[INFO] tello.py - 422 - Send command: 'takeoff'
[INFO] tello.py - 446 - Response takeoff: 'error'
[INFO] tello.py - 422 - Send command: 'takeoff'
[INFO] tello.py - 446 - Response takeoff: 'error'
[INFO] tello.py - 422 - Send command: 'takeoff'
[INFO] tello.py - 446 - Response takeoff: 'error'
Traceback (most recent call last):
...

It seems that there is a general problem with the takeoff()command because when I tried the manual-control-pygame.pyexample some things seem to work fine (connection worked well and I got images from the camera on a separate window) but also here, something seems to be wrong with takeoff() command.

Help would be very much appreciated!

EDIT: I tried a small delay with time.sleep(8) after the tello.takeoff() command

That gave me:

[INFO] tello.py - 422 - Send command: 'takeoff'
[INFO] tello.py - 446 - Response takeoff: 'ok'

But, however the next command after the takeoff throws the next error.

tello.move_left(5) is an invalid command. The minimum amount a tello can travel is 50 cm i.e. tello.move_left(50) is the minimum possible.

Apart from that try to turn on the light, the tello takeoff command takes longer in bad lighting or wind conditions.
