Error not connecting - Exception: Did not receive a state packet from the Tello

[Hook12aaa]

I honestly don't know what I did differently this entire setup worked last time. Dependencies:

• I have a lan cable and a wifi card. The wifi card is connected to the tello drone
• DJITelloPy
• CV2

This was just a hack to attempt to connect the drone. ` from DJITelloPy import Tello import cv2.cv2 as cv2 drone = Tello() drone.connect()

def screen_shot(drone): drone.streamon() frame_read = drone.get_frame_read() for i in range(100): img = frame_read.frame grey = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY) frame_read.stop() return img

cv2.imwrite("../capture.jpeg",screen_shot(drone))

`The error I got and yes the drone was connected to the computer. I wish I knew why

[INFO] tello.py - 424 - Send command: command [INFO] tello.py - 441 - Response command: ok Traceback (most recent call last): File "C:\Users\anton\Documents\cross-colab\drone-project\OpenCV-drones\test.py", line 4, in drone.connect() File "C:\Users\anton\Documents\cross-colab\drone-project\OpenCV-drones\DJITelloPy\enforce_types.py", line 45, in wrapper return func(*args, **kwargs) File "C:\Users\anton\Documents\cross-colab\drone-project\OpenCV-drones\DJITelloPy\tello.py", line 529, in connect raise Exception('Did not receive a state packet from the Tello') Exception: Did not receive a state packet from the Tello`

Disable your firewall for the flight duration. To do this on PC: -Go to Control Panel -Go to System and Security -Go to windows defender and disable it

Be warned that if you disable the private windows defender your drone may be on public

For mac: edited /etc/pf.conf and add lines like these: pass in proto udp from any to any port 11111 pass in proto udp from any to any port 8889 pass in proto udp from any to any port 8890 You'll still need to disable and re-enable PF after that (sudo pfctl -d; sudo pfctl -E) so you would still need admin access.

^^ as mentioned by someone on ticket #71 This all comes from ticket #71

What are the steps to fix if running on a VM? Tried disabling firewall. Did not work.

turning off the firewall did not work for me on windows 10, using python 3.7 ... I still get the exception "Did not receive a state packet from the Tello"
