Project Status
Last reviewed: 2026-07-11.
The main firmware builds and runs on the EMW3165. The current implemented surface includes:
- Wi-Fi setup, saved networks, captive portal, and station/AP fallback
- Embedded HTTP UI and shared status/settings API
- MQTT 3.1.1 telemetry and Home Assistant discovery
- Browser-based F411 application updates with staged rollback
- Read-only Bluetooth access to capabilities, status, scans, and saved networks
- Complete stock backup and restore of F411 internal flash and external SPI flash
The automated baseline is 10 host C suites, the web UI tests/build, and the 21-check live-device smoke test. See Development and Testing for commands and coverage.
Bluetooth exposes four read-only operations. Join, settings, reset, and other mutations remain locked because the BI201 service accepted connections and writes without an authorization prompt during bench testing. They should not be enabled until Rewair has an authenticated application session. Firmware OTA will remain Wi-Fi-only. See Bluetooth Transport.
Normal upload, install, reboot, and health confirmation have passed on the bench. Destructive tests for power loss during copying and forced trial-boot rollback remain pending. See Firmware Updates.
The internal-flash and SPI-flash backup/restore paths have validation and size/checksum guards, but the combined Step 0 workflow does not yet have a documented full stock backup → Rewair install → stock restore round-trip on a disposable unit. Complete that before treating recovery as field-proven.
