DEVLOG #26

I have completed, soldered, and tested the third and hopefully final PCB revision. Everything works, but the ground plane made soldering significantly more difficult than expected. Even with thermal reliefs around the solder pads, the plane acted like a heat sink, dissipating heat across the entire board.

The shift to a browser-centric approach is progressing: the Tauri desktop app and its associated release pipeline are being removed, while hardware control is being moved to a standalone “loopback crate.” This crate handles tasks such as device discovery, serial access, provisioning, flashing, OTA updates, and WASM integration. This work is currently ongoing.

The server now protects the /api/field and /ws/field endpoints using Bearer authentication and keeps auto mode offline until real data is available. An explicit simulated source is required for simulation.

mmWave transmission has been improved but still exhibits a sequence loss rate of 13.1%, causing the radar preflight to remain blocked. The causes of the remaining loss still need to be investigated, particularly regarding channel conditions, the startup process/ARP, and Wi-Fi airtime and scheduling. The calibration offset for “Phase 1” on RX3 also remains unresolved.

Next steps: fixing the RX3 offset, completing the migration to the browser/control setup, and re-running the radar preflight.
