Summary.md

Drone Communication Protocol Specification (Model: FLOW-UFO / Similar)

1. Wi-Fi Network

  • The drone acts as a Wi-Fi access point (SSID varies by model).
  • Default IP address of the drone: 192.168.1.1
  • Accepts only one client device at a time.

2. Control Communication

  • Protocol: UDP

  • Port (Destination): 7099

  • Command Packet Format: 2 bytes

    • Example: 01 01 (Confirmed to trigger takeoff)

  • Client (Phone/App) sends this packet to the drone to initiate commands.

  • Drone (192.168.1.1) sends telemetry-like responses (11-byte UDP packets) to the client on dynamic ports.

3. Video Stream

  • Protocol: RTSP over TCP
  • Port: 7070
  • Stream URL: rtsp://192.168.1.1:7070/webcam
  • Codec: MJPEG (Motion JPEG)
  • Resolution: 640x384
  • Frame Rate: ~21.4 fps
  • Color Format: yuvj420p

4. Video Notes

  • The stream may experience packet drops or skipped frames over Wi-Fi.
  • RTSP negotiation begins with standard OPTIONS/SETUP requests to /webcam.
  • Compatible with tools like FFplay, VLC, OpenCV, and FFMPEG.

5. Port Scan Observations

  • Open TCP Ports:

    • 8080 (possibly HTTP interface, not used for video)
    • 7070 (RTSP stream)

  • Closed Ports: 554, 8554, 8888, etc.

6. Tools Used for Analysis

  • Traffic Capture: PCAPdroid (Android)
  • Analysis: Wireshark (macOS), Nmap, FFplay
  • Command Replay: Python UDP sockets
  • Video Playback: VLC, FFplay, OpenCV
