# Holy Stone H120D: reconstructing drone Wi-Fi control and video traffic

> Holy Stone H120D research maps the drone’s Wi-Fi command, camera and video exchanges using APK decompilation, packet captures and ARM library disassembly. It documents UDP 8080 control frames, UDP 8088 camera commands and H.264 video on TCP 8888, with Python clients and an Arduino controller sketch.

## Requirements & limits

- **Prerequisites:** A Holy Stone H120D drone and connection to its Wi-Fi network; Python 3.8+ for the scripts.
- **Prerequisites:** ffplay is required for the live video example; Arduino Nano 33 IoT is used by the autonomous controller sketch.
- **Limits:** Variable joystick-axis control over Wi-Fi remains untested at high confidence.
- **License:** No licence file in the repository.
