DJI Ryze Tello PS3 Pad Controller

Web application displaying Ryze Tello's state and stream, allowing to control a drone with PS3 pad.

Application uses:

• Gamepad API
• socket.io: sending drone state / control commands
• JSMpeg: drone stream player using websockets
• ffmpeg

Running

0. Install ffmpeg.
   Install app dependencies:

1. Build app:

   yarn build
   yarn server:build
   

2. Connect to Tello's WiFi network.

3. Start server:

Help

To detect pad on Windows 10 I had to install ScpToolkit.

Todo
