Without this, breathing and heart-rate reports were 2× the true value. Added a comment tying the constant to the callback rate gate. 3. **Removed disabled probe-injection infrastructure** — dropped the forward declaration, the `CSI_PROBE_INTERVAL_MS` define, six static variables (`s_probe_timer`, `s_probe_tx_count`, `s_probe_tx_fail`, `s_ap_bssid`, `s_ap_bssid_known`), and three functions (`csi_send_probe_request`, `probe_timer_cb`, `csi_collector_start_probe_timer`). None were reachable. `csi_inject_ndp_frame()` reverted to the original ADR-029 stub. Can be revived from this commit's parent if needed. 4. **Cleaned `sdkconfig.defaults`** — removed the SPIRAM prose and commented-out `# CONFIG_SPIRAM is not set` line. Kept only the live `CONFIG_ESP_WIFI_EXTRA_IRAM_OPT=y` with a concise rationale. 5. **Bumped firmware version 0.6.1 → 0.6.2** and added four `[Unreleased]` CHANGELOG entries covering the SPI cache crash fix, the `filter_mac` / `node_id` clobber defense, the sample-rate correction, and the `write_flash` command-form revert. Net: +39 / -128 across six files. Validation in this devcontainer: - Static sanity on modified C files: braces balance (csi_collector.c 59/59; edge_processing.c 96/96), zero dangling references to removed probe-injection symbols. - Rust workspace tests and Python proof not executed here — cargo not installed and pip blocked by PEP 668. Deferring hardware build + flash + miniterm verification to @ruvnet's COM7 per his offer in the review comment.

The primary flash command was already correct. +- **Firmware: SPI flash cache crash under high CSI callback pressure** (RuView#396, #397) — ESP32-S3 nodes crashed in `cache_ll_l1_resume_icache` / `wDev_ProcessFiq` after ~2400 callbacks when the promiscuous filter admitted DATA frames at 100–500 Hz. Fixed by narrowing the filter mask to `WIFI_PROMIS_FILTER_MASK_MGMT` (~10 Hz beacons), adding a 50 Hz early callback rate gate (`CSI_MIN_PROCESS_INTERVAL_US`) that drops excess callbacks before any processing work, and enabling `CONFIG_ESP_WIFI_EXTRA_IRAM_OPT=y` as defense-in-depth. Stability validated with a 4-min-per-node soak. +- **Firmware: `filter_mac` / `node_id` clobber by WiFi driver init** (#232, #375, #385, #386, #390, #397) — `g_nvs_config` can be corrupted during `wifi_init_sta()` on some devices (confirmed on `80:b5:4e:c1:be:b8`), reverting `node_id` to the Kconfig default and producing garbage MAC-filter reads in the CSI callback (100–500 Hz). New `csi_collector_set_node_id()` API called from `app_main()` **before** `wifi_init_sta()` captures both fields into module-local statics (`s_node_id`, `s_filter_mac`, `s_filter_mac_set`). `csi_collector_init()` now runs a canary that distinguishes "early≠g_nvs_config" (corruption confirmed) from a no-op match. All CSI runtime paths use the defensive copies exclusively. +- **Firmware: `edge_processing` sample rate mismatch** (#397) — `estimate_bpm_zero_crossing()` was called with a hard-coded `sample_rate = 20.0f`, but MGMT-only promiscuous delivers ~10 Hz. Breathing and heart-rate reports were 2× too high. Corrected to `10.0f` with an explicit comment tying it to the callback rate. +- **`provision.py` esptool command form** (#391, #397) — ESP-IDF v5.4 bundles `esptool 4.10.0`, which only accepts `write_flash` (underscore). Standalone `pip install esptool` v5.x accepts both forms but prefers `write-flash`. #391 switched to `write-flash` which broke the documented ESP-IDF Python venv flow; #397 reverts to `write_flash` (works with both esptool 4.x and 5.x) with an inline comment warning future maintainers not to "re-fix" it. +- **`provision.py` esptool v5 dry-run hint** (#391) — Stale `write_flash` (underscore) syntax in the dry-run manual-flash hint now uses `write-flash` (hyphenated) for esptool >= 5.x. The primary flash command was already correct. - **`provision.py` silent NVS wipe** (#391) — The script replaces the entire `csi_cfg` NVS namespace on every run, so partial invocations were silently erasing WiFi credentials and causing `Retrying WiFi connection (10/10)` in the field. Now refuses to run without `--ssid`, `--password`, and `--target-ip` unless `--force-partial` is passed. `--force-partial` prints a warning listing which keys will be wiped. - **Firmware: defensive `node_id` capture** (#232, #375, #385, #386, #390) — Users on multi-node deployments reported `node_id` reverting to the Kconfig default (`1`) in UDP frames and in the `csi_collector` init log, despite NVS loading the correct value. The root cause (memory corruption of `g_nvs_config`) has not been definitively isolated, but the UDP frame header is now tamper-proof: `csi_collector_init()` captures `g_nvs_config.node_id` into a module-local `s_node_id` once, and `csi_serialize_frame()` plus all other consumers (`edge_processing.c`, `wasm_runtime.c`, `display_ui.c`, `swarm_bridge_init`) read it via the new `csi_collector_get_node_id()` accessor. A canary logs `WARN` if `g_nvs_config.node_id` diverges from `s_node_id` at end-of-init, helping isolate the upstream corruption path. Validated on attached ESP32-S3 (COM8): NVS `node_id=2` propagates through boot log, capture log, init log, and byte[4] of every UDP frame. diff --git a/firmware/esp32-csi-node/main/csi_collector.c b/firmware/esp32-csi-node/main/csi_collector.c index a67134a34..6beb99631 100644 --- a/firmware/esp32-csi-node/main/csi_collector.c +++ b/firmware/esp32-csi-node/main/csi_collector.c @@ -102,9 +102,6 @@ static uint8_t s_hop_index = 0; /** Handle for the periodic hop timer.
