Hi, I get this error response: error Run timeout each time I try run each of the commands (using Single_Tello_Test/tello_test.py script):

go 80 0 0 20 m1 or jump 80 0 0 20 90 m1 m2

this is my commands file:

command
mon
delay 1
takeoff
delay 5
go 80 0 0 20 m1
delay 5
land

and this is how the log looks like:

id: 0

duration: 1.662

I tried to increase and decrease the delays, didn't correct the behavior.

The delay command as much as I understand should be set according to the duration of the command execution mentioned in the log, am I right ?

I.e the delay should be >= of the duration of the command executed before the delay command am I right ? e.g:

duration of go 80 0 0 20 m1 command is duration: 15.183 so the commands should look like:

mon
delay 1
takeoff
delay 5
go 80 0 0 20 m1
delay 20
land

as the last delay command delay 20 where 20 >= 15.183, is that correct ?

I've already updated FW and calibrated IMU without any trouble.

I'm Getting the following error while running main.py

Traceback (most recent call last): File "main.py", line 14, in main() File "main.py", line 7, in main drone = tello.Tello('', 8889)

I don't know why with me it did but, my tello just broke because of your script. tello_state.py has ripped it. If I start my tello now it immediately turns off again. Help would be nice.

Where is this behavior documented (where a packet length not of 1460 is used to partition a frame)? I'm having trouble finding any official sources which talk about the protocol.

Hi, I'm unable to get the Single_Tello_Test working with my Tello EDU drone. This works fine with my older original Tello.

Here's the transcript:

Thanks.

as mentioned earlier, install.bat and install_manual.bat closes the cmd prompt after admin rights. I have manually tried installing all dependencies, but I need h264decoder to be built. Any suggestions?

Hello!

I would like to perform the simplest Hello World test from the very beginning using Python programming language. It appears that I have to run Python on a desktop/notebook but I have a few elementary questions since the documentation didn't illustrate the steps (at least for my understanding):

1. Do I connect my desktop/notebook to the drone using the right USB cable to the drone and then run the corresponding Python program?
2. I do not have 192.168.10.x in my LAN. My subnet is completely different. What are the steps and limitations in changing the drone's IP address?
3. Is the tello package (that I need to import for my custom Python efforts) the single tello.py file in this repository?

I am sure that these questions have answered many, many times but sadly owing to my inability to find these answers anywhere I had to resort to raising them here. My apologies.

Thanks for your guidance in helping me get the minimal Hello World up and running. I simply need some detailed instructions on establishing a development environment (any platform will do - Windows, Linux/Ubuntu, Raspberry Pi OS, etc.). Appreciate your patience in reading this plea for help.

Kind regards.

How can I read frame from tello udp.When I used djıtellopy 1.5 ı get very low fps.Please help me.And ı get this error; [h264 @ 0000025498d6df80] error while decoding MB 17 34, bytestream -12 [h264 @ 0000025498dbbc40] error while decoding MB 42 8, bytestream -9 [h264 @ 00000254992168c0] error while decoding MB 3 25, bytestream -8 [h264 @ 0000025498d6d840] error while decoding MB 47 43, bytestream -8

Hi, I got this error to run .\Tello_Video_With_Pose_Recognition\main.py after running the .\Tello_Video_With_Pose_Recognition\tello_pose.py

cv2.error: OpenCV(3.4.2) C:\projects\opencv-python\opencv\modules\dnn\src\caffe\caffe_io.cpp:1121: error: (-2:Unspecified error) FAILED: fs.is_open(). Can't open "model/pose/mpi/pose_iter_160000.caffemodel" in function 'cv::dnn::ReadProtoFromTextFile'

Can you help me?

Hello,

I am trying to use this SDK with a Tello EDU connected to a separate AP, but the video socket bound to port 1111 never seems to get any data.

The receive socket bound to 8889 is able to get responses, and I can send commands without issue.

This is my code:

import time
from tello import Tello

drone = Tello('', 8889, tello_ip='192.168.2.108')

drone.send_command('battery?')
time.sleep(0.5)
print(drone.get_response()) # 72

frame = None
while frame is None:
    frame = drone.read()
    print(frame) # None
    time.sleep(0.5)
    

print(frame)

drone.read() always returns None when connected to the external AP, but it works fine and returns data when the Tello is acting as its own hotspot.

~~Should video feed to work with a separate AP? Is it a limitation of the SDK, or a configuration error on my end?~~

Edit: My question is in the FAQ:

Q8:Can Tello EDU transmit video streams externally in station mode (send ap 'ssid' 'password' command for Tello EDU)?

A8:This feature is currently not supported.

Hi, I would like to have Tello connect to an existing WiFi network in my building as opposed to connecting to the network that the drone generates. Is that possible to set up? I'm flying over long distances indoors, and the signal strength falls quickly, even if I use one extender.

Hello, this project seems good, but when I run the code, there is serious video latency, the image will blur for 2 seconds and restore and blur again with the error below can anyone helps?

The Tello SDK documentation mentions that the Tello EDU returns an "ok/error" response for the "emergency" command. https://dl-cdn.ryzerobotics.com/downloads/Tello/Tello%20SDK%202.0%20User%20Guide.pdf

However, I see that my EDU drone doesn't return an "ok" response even though it emergency lands appropriately.

Is this a known issue?

I can't download the file "pose_iter_160000.caffemodel", so I found the file on the Internet and copied it to the document. But when I ran the project, it couldn't work.
