Godot Engine - Tello Control Node

With this Addon you can control your Ryze/ DJI Tello Drone with Godot. It is also possible to read the telemetry with this Node.

Because godot does not support h264 there is no video or photo support. But i accept pull request if you want to implement it.

You can find the API documentation here under "Tello SDK"

Usage

Add the Tello Node to your project tree. To connect with the drone first connect to the wifi of the drone. After that you can call the start() method of the node.
