francescopace/espectre 3.0.0-rc2

v3.0.0-rc2 - Signed firmware, CSI capture controls, and standalone SDK builds

on GitHub

Highlights

• Verify browser downloads with signed catalogs; Native and ESPHome require signed OTA updates.
• Build all first-party frontends against extracted SDK bundles through ESPECTRE_SDK_ROOT.
• Select CSI capture profiles at build time and try experimental wifi_raw traffic on supported chips.
• Read selected diagnostics over Direct HTTP and MQTT, including frontend loop timing.

Firmware and sensing

• Native OTA uses the shared firmware catalog; rolling firmware and SDK manifests use channel names.
• Reject invalid CSI and report stale sensing as unavailable, preserving raw CSI framing.
• Add auto, lltf, and ht-vht capture profiles; 5 GHz detection remains uncharacterized. See CSI.md.
• wifi_raw requires auto or lltf and is disabled on ESP32-C6; ping remains the default.
• Allow custom IPv4 destinations for internal traffic generators. See SDK.md.
• Default station TX rates to 6.5 Mbps on classic ESP32 and Auto elsewhere, independently of sensing.
• Resume CSI after reassociation or roaming with retained IPv4 state, without requiring another GOT_IP event.
• Pin CPU clocks per target, reclaim Native IRAM, and save 6 KiB in the C++ raw CSI queue.

SDK and diagnostics

• Derive SDK versions from packaged metadata or integrator overrides, independently of firmware versions; missing or incomplete metadata uses 0.0.0.
• Move Improv Serial support outside the SDK and share command validators with ESPHome controls.
• Micro-ESPectre Direct validates JSON and parameters; non-empty bodies require the JSON media type.
• Share csi_hw_error_pps across C++ and MicroPython, and expose C++ frontend loop duration as loop_time_ms.

Web tools, builds, and maintenance

• Show the newest Release or Preview firmware on the home badge, and suggest replacement routes on 404 pages.
• Reduce benchmark HTTP traffic, recover stale SSE readiness, and report setup failures with diagnostic evidence.
• Update ESPHome to 2026.9.0, host dependencies, and website packages, including the Rollup security fix.
• Add dependency audits and quality reports; block releases on license violations, scanner failures, and applicable high, critical, or unscored CVEs.
• Store build packages, caches, and audit output under .cache/.

Breaking changes and migration

• Diagnostics without fields return a catalog; use explicit fields or ["*"] for values. Upgrade clients and firmware together. See API.md.
• OTA services, version comparison, release catalogs, and OTA types move from the SDK runtime to shared frontend code.
• Replace RuntimeFrontendController::quiesce_for_ota() with quiesce(); replace espectre_firmware_version() calls by supplying the application version through runtime interfaces.
• Remove RuntimeDiagnosticsSample::csi_classified_pps and csi_provenance_rejected_pps, plus diagnostics csi_classified_total and csi_estimate_length_mismatch_total.
• Remove TemporalCsiSampler counters duplicate_packets, missing_timestamp_packets, and gap_resets.
• Convert CONFIG_ESPECTRE_WIFI_TX_RATE_MBPS overrides to strings "0", "6", or "6.5", or remove them to adopt target defaults.
• Update saved CONFIG_ESPECTRE_DIRECT_HTTPD_TASK_PRIORITY overrides to adopt the new default of 1.
• Rebuild and flash Micro-ESPectre firmware before deploying the application, which now requires espectre_native_wifi.
• Use USB when switching between unsigned personal builds and signed official firmware. Matter still has no OTA. See SETUP.md.
