CAMERA_DOWNWARD Tello (non-EDU)

[Ruben.D]

HI, I've been trying to find out why I get an error in low light environments and the tello drifts off its path.

I have found out that the tello uses a time of flight sensor, which I tested and it's pretty accurate. The second way it does position hold is through the second downward facing camera.
Is there any way to get access to it in python?? I'm using the djitellopy library and the command listed on github doesn't work with my Tello.

set_video_direction(CAMERA_DOWNWARD) is undefined it says in PyCharm.

I'd appreciate if someone could help!

djitellopy has no function set_video_direction()

But you can use the generic send_command_with_return() function as described here: Tello - DJITelloPy API Reference

Switching to the downward facing camera would be like:
drone.send_command_with_return("downvision 1")

Please let us know, if it also works with non-EDU.

Thank you, I'll give it a try. Hoping it works on mine

Does anyone have an example of images capture from the down camera? Or even what the specs are for that camera?

You can see it here: SDK 3.0 for Tello EDU

Hi, unfortunately the non-EDU version sends back an unknown command message for downvision. I don't know why it wouldn't be possible to work on the non-EDU. I wish they would add that feature through a software update but probably won't happen.
