SDK 3.0 for Tello EDU

Mike Shock · May 27, 2021

I've upgraded my Tello EDU to the firmware v02.05.01.17 (released 2021-05-18) and found out that now it reports that the version of the SDK is 3.0. Some new interesting and useful commands are available now not only for Tello Talent, but for Tello EDU as well.
You may read about them in the manual: https://dl.djicdn.com/downloads/RoboMaster+TT/Tello_SDK_3.0_User_Guide_en.pdf
I've tried some of them using the Tello gem for the Ruby programming language.

I like the "motoron" / "motoroff" commads - they're good for cooling the drone when it's on the ground while I'm testing a program.

Newbie here, I just started using djitellopy to learn how to program this drone. Outside of the new motor commands am I missing out of any new commands by not using the official sdk?

I think, only commands of the SDK 2.0 are implemented as methods in the DJITelloPy package. But it has a method 'send_command_with_return(str)'. With its help, you can send to your drone any command of the SDK 3.0.
For example: tello.send_command_with_return("motoron") or tello.send_command_with_return("reboot").
But you should have the v02.05.01.17 firmware version in your Tello EDU/Talent to execute SDK 3.0 commands.

Thank you! I did not know of that command.

hiya - I've just updated tello-asyncio with SDK 3 support if you fancy giving it a go...

eg the keep_cool.py example uses motoron/motoroff to switch motors on in the new low speed mode

Hey,

im the current maintainer of djitellopy.
This sounds very interesting. One major issue with the old EDU firmware had was not being able to stream video while in wifi station mode. I.e. when flying a swarm of drones having them all connected to one wifi AP it was not possible to stream video. Maybe this is now possible with the new `port info vedio` command? I will have to do further investigations.

Apart from that most of the new stuff seems to be robomaster tello talent related.

Its working great, still learning the ropes but anything that hasn't worked has been user error

Good news! I'll certainly try your library to control my Tellos.

Has anonye figured out how to use the command 'wifisetchannel xxx' for 5 Ghz Wifi, or whether it is possible to set the Tellomaster to 5ghz with it?
It is working fine for 2.4 Ghz but since there are only 14 channels at 2.4 ghz I would assume this command should be compatible with setting 5 ghz wifi as well. (Otherwise a placeholder for 3 digits would not make any sense for me)

Oh, and has anonye tried sending a video stream while being in Access Point Mode (by using the command 'port info vedio')? It would be amazing if the drone is finally capable of transmitting video through a Router.

This is fantastic, just hat I was looking for.

Do you have to use python for this? Can you use scratch? Might make it easier for my class.

You can use any language that has a library to send commands (text strings) via Wi-Fi by UDP protocol.
Scratch and Python are among them.
There's a DJI supported educational IDE, called "Mind+": RoboMaster TT - MindPlus wiki . You can download it from here: download
Maybe you'll find it useful...

Thanks you do good work.

Thanks for your sharing! I am new to tello programming. I want to know, can tello do a flip_backward when I call this function in djitellopy.py ( I use the normal tello, not edu and not talent )

I try to make a tello flip in this code, but failed:

tello = tello.Tello()
tello.connect()
tello.takeoff()
tello.flip_backward()

I am very appreciate that if you can answer my question, thanks a lot!

I'll try to do this with my Tello. It should work with all variants (T, TEdu, THero, TTalent). I only know that flips are not performed when the battery is low.

thanks very much!! I only use the app on my phone to make tello flip, not by programming in pycharm.

hello, here I have a news for you, finally we found that it's the floor which is too black and no pattern on it, after we just put some posters on the floor, it worked!
thank you ~~

This code works well:

tello = tello.Tello()
tello.connect()
tello.takeoff()
tello.flip_back() # the right name of the method, NOT flip_backward()
tello.land()

There's also a flip(direction) method that takes a one-character parameter: 'l', 'r', 'f', 'b' (as described in the SDK manual).
