For Windows#

Download#

Go to Releases on GitHub and download the file named windows.zip.

Extract#

Extract the downloaded zip file to a location of your choice.

Launch#

After connecting to Tello, launch Scratch3-Tello.exe, which is contained in the extracted folder.

Once launched, click the Extensions button in the lower-left corner and select the “Tello” extension. The blocks for programming Tello will appear.

Troubleshooting#

If Tello does not take off after running the takeoff block, commands from other blocks may be queued and waiting to execute. Running the “Reset command queue” block should resolve the issue.
