README
README.mdCentral intelligence unit
End goal: ESP32 that is Sena and Cardo Mesh compatible. Replaces Sena completely. Also, built in HUD inside of Goggles.
Status
The Sena Mesh 3 air protocol has been recovered from firmware by static analysis: frame format, packet subtypes, discovery and admission, routing, timing, audio packing, and the protected-record crypto.
- Mesh protocol static analysis — current reference, including the ESP32-C6 implementation requirements and the over-the-air capture plan.
- First-pass ESP32 feasibility — superseded baseline, kept for the FCC and firmware-distribution evidence.
tools/mesh3.py— clean-room reference implementation;python3 tools/mesh3.py verifyre-derives every published vector from the local image.firmware/— downloaded images, extracted components, andmanifest.jsonwith verified hashes.
Open items are capture-dependent, not static: the lower MAC/FCS boundary, the exact Speex submode, and the predicted Group Mesh network-ID truncation.
Development
Run npm install after cloning to install the Husky Git hooks. Before each
commit, the pre-commit hook runs cargo check-esp against every workspace
crate for the ESP32 target.
