The author's reported result and independent confirmation are separate checks. - AI involvement - Reported models: Claude. Tools: Flutter, Rust, MediaCodec, ffmpeg. The writeup below describes the work attributed to AI. - Reported result - Partial. This is the directory's source-based outcome classification. - Independent confirmation - Not reported. - Human work and limitations - The project explicitly avoids geofence defeat and secret key extraction, focusing on structural analysis and interoperability for owned hardware. ### Original sources ## What was done Reverse-engineering and interoperability software enabling direct app-to-bird communication with the DJI Phantom 3 Professional, utilizing a pure-Dart DUML implementation and a Rust control core. The awto-dji project provides interoperability software to communicate directly with a DJI Phantom 3 Professional. The architecture consists of a Flutter application featuring a pure-Dart DUML codec and a Rust-based direct-control core. Reverse-engineering analysis has focused on structural analysis of the protocol, including telemetry scanning and public-airspace safety gates. The project documents a discrepancy in FPGA command ID numbering, where firmware dispatcher traces do not reconcile cleanly with APK command sets. Recent development includes a live H.264 video decoder, though it remains untested against a real NAL stream from the aircraft. The author reports that video decode issues were traced to a capture-completeness gap rather than a pipeline bug, as the stream lacked SPS/PPS/IDR frames. Additionally, the project investigated DJI Assistant 2 debug mechanisms, finding that debug mode can be accessed via launch arguments, though it is not yet confirmed if this enables P3 support. The project maintains a [README](https://raw.githubusercontent.com/awto-au/awto-dji/HEAD/README.md) and extensive documentation of its reverse-engineering efforts.
