Tello EDU Mission Pad Accuracy / Vision

My Tello EDU finally arrived. I'm super excited that Tello EDU allows for swarming, hoping to design some great drone choreography.

The big breakthrough is the mission pads. I need to be able to say go to X Y Z and have it actually go there.
The result, so far, is ... underwhelming. Most of the time it doesn't see the mission pads, and if it does, it's not particularly accurate in where it goes. And if it doesn't see the pad already, it just gives up with an error message.

Who here has had luck with getting mission pads to work consistently? Any tricks?

From searching, it looks like there's no way to get the downward camera stream, so I can't see what information Tello EDU is getting. Is that correct?

Also, is there a way to point the App (either Tello or Tello EDU) at an IP address? I'd like to leave Tello EDU set up to automatically connect to my AP and still be able to control it and see video through the App.

Thanks for your help!

I'm interested in this too. I have thought about it. One way to try would be as follows:

  1. Setup a wifi network, BSSID name is not important, lets call it tello-dev
  2. IP address subnet of this wifi network would need to be 192.168.10.0 with a mask of 255.255.255.0
  3. Wifi router (or anything else) can't have the IP Address of 192.168.10.1, this must be reserved for the tello EDU
  4. Connect laptop to tello EDU network, using SDK commands get tello to connect to tello-dev wifi network
  5. Confirm tello has the ip address 192.168.10.1
  6. Connect phone(running official tello/tello EDU apps) to tello-dev wifi network
  7. Assign IP address of phone(running official tello/tello EDU apps) to 192.168.10.2 with a mask of 255.255.25.0
  8. Run tello/tello EDU apps on phone to see if it will connect to tello

One thing to note, you can have the tello EDU connected to a wifi network and not have it in SDK/command mode. ie: the tello boots up and connects to a wifi network, the yellow light is flashing quickly to indicate ready to receive mode. Only after issuing the SDK mode command to the tello does the light turn green. I think because of this, as long as one can replicate the tello peer-to-peer wifi network with a regular wifi network then it should allow the app to connect and fly the tello as usual...

I will try this soon myself. Let us know how you go!

Cheers,
ph2t,

Oh this is absolutely fantastic!!! @Marcochan would you be willing to share some of how you made this? I have soooo many questions!

How did the drones keep track of the mission pads? I didn't see any failures in the video.
How did you lay out the mission pads? What pattern worked?
Are you calling specific Mission Pad numbers, or just whichever one is closest? (-2)
Were you using "curve?" - if so, how? I have yet to get it to execute without error-ing out?
Were you controlling the LED? The blinking looked good.
Would it be possible to share some of the code, or at least the commands you used to get such great motions?
Thank you so much for your great work!!
