Two FW changes closing both Open Items in ADR-108:
1. POST /ota/recalibrate on port 8032 erases csi_cfg/gl_agc, gl_fft,
gl_ap_mac then esp_restart() — operator can force a full re-cal
without USB. Reuses ota_check_auth Bearer-token guard.
2. New csi_cfg/gl_ap_mac (6-byte blob) saved alongside AGC/FFT.
Boot-time short-circuit compares saved BSSID with current
esp_wifi_sta_get_ap_info().bssid; mismatch → discard cache, run
full calibration. All-zero (legacy NVS without MAC) treated as
wildcard so existing deployments don't re-cal on first upgrade.
Verified by OTA-flashing both sensors (192.168.0.100, .101) and
calling /ota/recalibrate via curl — both returned the expected JSON
and came back online ~15 s later running fresh calibration.

ADR-108: after the first successful gain-lock on FW, save the AGC and
FFT median values to NVS (namespace "csi_cfg", keys "gl_agc" / "gl_fft").
On every subsequent boot the FW loads them and immediately calls
phy_force_rx_gain / phy_fft_scale_force without waiting 300 packets
(~3-12 s) for fresh calibration.
Mechanics:
rv_gain_load_from_nvs / rv_gain_save_to_nvs — small NVS helpers in
the gain-lock module.
rv_gain_lock_process — `s_nvs_checked` static gate triggers a one-
shot load on the first packet after boot. If
a saved AGC ≥ MIN_SAFE_AGC is found, lock
immediately + mark locked. Otherwise fall
through to the existing 300-packet sampler.
Existing lock branch — after the median + force_*, save to NVS so
the next boot has the values.
Verified live: second OTA → 44 Hz raw CSI at WS in the first 3-s
sample after boot (was ~5-12 s gap before). Both nodes flashed via
WiFi (no USB), no MIN_SAFE_AGC skip in operator's deployment (AGC=44).
Tradeoff: NVS values are tied to sensor location + AP MAC + channel +
antenna. If the operator moves the sensor or swaps the AP, stale
values may be slightly off-optimal until they re-trigger calibration.
Today: erase NVS keys via console; future: dedicated FW endpoint.
Closes ADR-106 open item #1: server now receives the real WiFi RX
timestamp from the sensor's hardware controller instead of stamping
on receipt with SystemTime.
FW (csi_collector.c csi_serialize_frame):
Append uint32_t = info->rx_ctrl.timestamp (µs since FW boot,
monotonic per ESP-IDF docs) as 4 trailing bytes after I/Q data.
Header layout unchanged → old server parsers still work (they
ignore tail bytes per existing `if buf.len() >= expected` check).
Server (parse_esp32_frame):
Opportunistically read trailing 4 bytes as u32 LE into
Esp32Frame.sensor_timestamp_us. Old FW → None, new FW → Some(µs).
udp_receiver_task uses sensor timestamp when present, falls back
to server SystemTime if not. Result published as NodeInfo.timestamp_us.
Flashed both sensors via OTA (no USB dance):
192.168.0.101: ota_0 → ota_1 ✓
192.168.0.100: ota_1 → ota_0 ✓
Live verify: WS timestamps now sub-1e12 (sensor monotonic, ~39s
after FW boot), Δ between successive frames = 43.3 ms ≈ 23 fps
sampling jitter, sub-ms precision. Cross-node skew = sensor boot
time delta (here ~292 ms). For sync the host can subtract per-node
boot offset learned from the first packet pair.
Ports Francesco Pace's ESPectre gain-lock (GPLv3) to RuView FW: medians
AGC and FFT scale over the first 300 packets after boot, then freezes
them via phy_force_rx_gain / phy_fft_scale_force. With both sensors
locked and proper AP→body→sensor geometry, a 30-s × 3-state capture
(empty / still / walk) now separates by ×3.4–×5.9 instead of ±0.02
within ±0.10 noise as in ADR-099.
Adds static/raw.html — per-node 56-subcarrier amplitude bars + RSSI/
broadband traces, no DSP, for live calibration.
ADR-100 documents the technique, boot calibration values for the
operator's deployment (AGC=42/44, both APPLIED), and the verified
three-state separation table.
Operator's household environment showed CSI-variance presence detection
failing — empty room produced HIGHER variance than an occupied room because
ambient WiFi noise (neighbour APs, retransmits, BT-coex) dominated the
broadband-variance signal at multi-meter range.
Deployed a TP-Link TL-WR841N in WISP mode as a dedicated isolated AP for
the sensors:
* Sensors associate only with TP-Link_8340 (clean channel)
* TP-Link bridges to the household AP, NAT-forwards sensor UDP to the Mac
* Mac keeps its primary household-AP association — no LAN reconfig needed
* Empty-room variance dropped 50.7 → 35.8 (-30%)
Replaced presence classification with RSSI MAD-Δ override:
* Per-node rolling 120-sample (~10 s @ 12 Hz) window of frame RSSI
* Metric: mean(|Δrssi|) between consecutive frames — robust to int8
quantisation jitter
* Thresholds tuned for the operator's geometry:
d < 0.20 → absent
< 0.55 → present_still
< 1.10 → present_moving
>= 1.10 → active
* Confidence field temporarily carries raw d for in-field threshold tuning
* CSI-based features (variance, motion_band_power, spectral_power) remain
in features.* for vital-sign signal-quality and multi-node fusion paths
UI / tooling:
* New static/spectrum.html — live signal console: combined classification,
all host-computed features (variance, motion_band, spectral, breathing
band, RSSI, dominant_freq, change_points), per-node FW signals, and a
60-second variance trace. Served via `python -m http.server 8091`.
* static/calibrate.html — simpler per-node motion/presence/RSSI bars
with peak-hold.
Desktop UI / discovery hardening (rolled in here because they came up
during this debug session):
* commands/discovery.rs: HTTP sweep limited to 2..=60 hosts (was 1..=254),
mDNS + UDP-broadcast paths disabled (current RuView FW doesn't advertise
them and they were burning CPU every poll cycle). Per-request timeout
set to 1500 ms with overall budget enforced via tokio::time::timeout +
futures::join_all (replaces the previous sequential select loop that
blocked on slow IPs).
* ui/hooks/useNodes.ts: poll interval 10 s → 30 s.
* ui/pages/Dashboard.tsx + NetworkDiscovery.tsx: merge new scan results
into existing list instead of replacing — discovery races sometimes miss
a node that was found a moment ago.
Firmware tuning:
* edge_processing.c: broadband-variance divisor /3.0 → /30.0 → /5.0
iterated; final /5.0 chosen for multi-meter geometry (sensor 1-3 m
from activity zone). DEBUG_MOTION_DSP scaffolding removed.
* csi_collector.c: CSI_MIN_SEND_INTERVAL_US 20 ms → 4 ms so the host can
see every available frame (real ceiling is the WiFi CSI callback rate).
Documentation:
* docs/adr/ADR-099 — full forensic write-up: measurement tables for sit/
walk/empty, the RSSI-Δ rationale, the WISP setup procedure, calibration
protocol for new deployments, and open items.
Verified end-to-end on hardware (sensors at 192.168.1.17/.19 → TP-Link at
192.168.1.14 → Mac at 192.168.1.21):
* UDP/5006 packets arrive ~12 Hz combined from both nodes
* Empty-room baseline d ≈ 0.49 measured (next: capture sit + walk to
finalize thresholds)
* Vital signs continue to populate (breathing 9–11 BPM stable)
* Two consecutive OTA round-trips remain functional after the change

End-to-end deployment fixes that took the two ESP32-S3 sensor boards
(room01, room02) from "boots but DSP frozen, OTA always rolls back" to
"motion/presence/breathing all live, two consecutive OTA round-trips
succeed". Full forensic write-up in docs/adr/ADR-098.
Firmware (firmware/esp32-csi-node/main/):
* csi_collector.c — remove esp_wifi_set_promiscuous(true): this call
silenced the CSI RX callback entirely on this silicon revision
(yield=0pps). Without it, callbacks resume at ~5-10 pps.
* edge_processing.c — root cause: incoming CSI frames carry 192
subcarriers but EDGE_MAX_SUBCARRIERS=128, so the size check
early-returned every frame and Step 8 (motion) never ran. Truncate
to 128 + warn once instead of returning.
* edge_processing.c — replace per-bin unwrapped-phase variance with
temporal variance of per-frame broadband mean amplitude. Empirical
separation on deployed hardware: empty 0.07-0.10, walking 3.5-14
(~44x). Scaled by /3.0 and clamped to [0,1].
* edge_processing.c — biquad fs 20.0 -> 10.0, matching the actual
callback rate (was halving the breathing passband).
* ota_update.c — OTA_WITH_SEQUENTIAL_WRITES -> OTA_SIZE_UNKNOWN to
erase the full target partition (stale tail of the previous larger
image was crashing the new image on boot, looking like rollback).
* ota_update.c — httpd_config_t.stack_size = 8192 (default 4 KB
overflowed in OTA verify path).
* main.c — log esp_reset_reason() and running_partition->label once
at app_main start, so OTA outcomes are visible without guesswork.
* sdkconfig.defaults — local deployment defaults: tier=2, display
disabled (no expander on these boards), 8192 timer stack.
Sensing server (v2/crates/wifi-densepose-sensing-server/):
* src/main.rs — parse_rv_feature_state() for the 0xC5110006
feature_state packet that RuView FW emits by default; this format
was previously unhandled. Wire ahead of parse_esp32_vitals.
* src/main.rs — BaselineTracker with hysteretic motion gating on top
of FW-reported scores, so UI sees clean boolean presence transitions.
* src/main.rs — refuse --source simulate; remove auto-fallback to
synthetic data. Production builds never run on fake signals.
* src/main.rs/csi.rs — parse_csi_lean() for legacy FW 5.47 CSV
packets; defence-in-depth for mistakenly flashed legacy sensors.
Desktop UI (v2/crates/wifi-densepose-desktop/):
* src/commands/discovery.rs — third discovery path: HTTP /status sweep
across the local /24 in parallel with mDNS/UDP. mDNS+UDP-beacon are
not advertised by current RuView FW. Replace sequential
for-task-in-tasks select-with-deadline (which blocked on slow
unrelated IPs) with futures::join_all + overall timeout.
* src/commands/server.rs — pass --bind-addr (was --bind); pass
RUST_LOG env instead of unsupported --log-level; auto-load bundled
wifi-densepose-v1.rvf next to the binary; reasonable defaults
(esp32 source, 0.0.0.0 bind).
* ui/* — keep last good node list when a poll returns 0 (discovery
is jittery on busy LANs); 8 s timeout (was 3 s); remove "simulate"
from DataSource enum and Sensing dropdown; default Sensing source
esp32.
Mobile UI (ui/mobile/):
* constants/websocket.ts — WS_PATH '/ws/sensing' + WS_PORT 8765 to
match the RuView sensing-server's WS endpoint (was the legacy
FastAPI /api/v1/stream/pose).
* services/ws.service.ts — derive WS host from serverUrl but use
WS_PORT; remove simulation fallback paths entirely (no
generateSimulatedData, no startSimulation on reconnect failure).
* stores/settingsStore.ts — serverUrl defaults to
http://100.123.189.10:8080 (deployed Mac's Tailscale IP), so the
phone connects from any network without LAN dependency.
* stores/matStore.ts — default dataSource='real',
simulationAcknowledged=true; no synthetic triage data.
* screens/MATScreen, VitalsScreen — hide simulation overlay/badge.
Docker:
* docker/docker-compose.yml — sensing-server host port 5005 -> 5006
to match the RuView FW's compiled CSI_TARGET_PORT default.
Documentation:
* docs/adr/ADR-098-esp32s3-csi-deployment-fixes.md — full forensic
ADR covering each decision, the empirical numbers that drove it,
the false hypotheses we ruled out along the way, and open items.
Verified on hardware (both nodes):
* motion empty < 0.05 (room01 0.018, room02 0.070)
* motion walking > 0.3 within 1-3 s, saturates at 1.0
* motion decay < 0.1 within 5 s after leaving
* breathing 21-22 BPM detected after ~30 s stationary
* two consecutive OTA round-trips succeed without USB intervention
* discovery finds both sensors via HTTP sweep in <2 s

csi_collector_init() never called esp_wifi_set_ps(), leaving the radio on
the ESP-IDF STA default WIFI_PS_MIN_MODEM. The modem then sleeps between
DTIM beacons; combined with the MGMT-only promiscuous filter (#396) the
CSI callback is starved and the per-second yield collapses toward 0 pps,
which is what users on a clean multi-node setup were seeing
(motion=0.00 presence=0.00 yield=0pps).
Force WIFI_PS_NONE before enabling promiscuous mode — the textbook
requirement for reliable CSI capture (every ESP-IDF CSI example does it).
New boot line: "csi_collector: WiFi modem sleep disabled (WIFI_PS_NONE)
for CSI capture". Battery duty-cycling is unaffected: power_mgmt_init()
runs after this and re-enables modem sleep when provision.py is given
--duty-cycle <100.
Builds clean for esp32s3 (idf.py build, 48% flash free).
Closes#521

* fix(firmware): move defensive node_id capture before wifi_init_sta()
The original defensive copy in csi_collector_init() (line 172 of main.c)
runs AFTER wifi_init_sta() (line 147), which on some ESP32-S3 devices
corrupts g_nvs_config.node_id back to the Kconfig default of 1.
Reproduced on device 80:b5:4e:c1:be:b8 (ESP32-S3 QFN56 rev v0.2):
- NVS provisioned with node_id=5
- Release firmware (no fix): seed receives node_id=1 (clobbered)
- This patch: seed receives node_id=5 (correct)
Changes:
- Add csi_collector_set_node_id() called from main.c immediately
after nvs_config_load(), before wifi_init_sta() runs
- csi_collector_init() now detects and logs the clobber if early
capture disagrees with current g_nvs_config value
- Fallback path preserved: if set_node_id() is never called,
init() still captures from g_nvs_config (backwards compatible)
Co-Authored-By: claude-flow <ruv@ruv.net>
* fix(firmware): defensive copy of filter_mac to prevent callback crash
The CSI callback reads g_nvs_config.filter_mac_set and filter_mac on
every invocation (100-500 Hz). If wifi_init_sta() corrupts g_nvs_config
(same root cause as the node_id clobber), the callback reads garbage
from the struct, leading to Core 0 LoadProhibited panic after ~2400
callbacks (~70 seconds of operation).
Extends the early-capture pattern from the node_id fix to also copy
filter_mac_set and filter_mac into module-local statics before WiFi
init runs. Adds canary logging to detect filter_mac corruption.
Observed on device 80:b5:4e:c1:be:b8 via serial:
CSI cb #2400 → Guru Meditation Error: Core 0 panic'ed (LoadProhibited)
→ TG0WDT_SYS_RST → reboot → crash again at ~2900 callbacks

* fix(firmware): MGMT-only promiscuous filter to prevent SPI cache crash
The WiFi driver's wDev_ProcessFiq interrupt handler crashes with
LoadProhibited in cache_ll_l1_resume_icache when promiscuous mode
captures MGMT+DATA frames (100-500 interrupts/sec). The high interrupt
rate races with SPI flash cache operations, corrupting cache state.
Changes:
- Promiscuous filter: MGMT+DATA → MGMT-only (~10 Hz beacons)
- CSI config: disable htltf_en and stbc_htltf2_en (LLTF-only)
LLTF provides 64 subcarriers (HT20) — sufficient for presence,
breathing, and fall detection. The 10 Hz beacon rate eliminates
the SPI flash cache contention that caused the crash.
Verified on device 80:b5:4e:c1:be:b8:
- Before: LoadProhibited crash at ~1600-2400 callbacks (every ~70s)
- After: 2700+ callbacks over 4.7 minutes, zero crashes
Backtrace decode confirmed crash in ESP-IDF closed-source WiFi blob:
_xt_lowint1 → wDev_ProcessFiq → spi_flash_restore_cache
→ cache_ll_l1_resume_icache → EXCVADDR=0x00000004 (NULL deref)

* fix(provision): write-flash → write_flash for esptool v5 compat
esptool v5+ rejects hyphenated subcommands. The provision script
used 'write-flash' which fails with "invalid choice". Changed to
'write_flash' (underscore) which works with both old and new esptool.
Co-Authored-By: Ruflo & AQE
* fix(firmware): 50 Hz callback rate gate + sdkconfig extra IRAM opt
- Add early rate gate in wifi_csi_callback at 50 Hz (defense-in-depth,
does not prevent crash alone but reduces callback execution time)
- Add null-data injection timer infrastructure (disabled — TX adds
interrupt pressure that triggers the SPI cache crash, RuView#396)
- sdkconfig.defaults: add CONFIG_ESP_WIFI_EXTRA_IRAM_OPT=y
- sdkconfig.defaults: document SPIRAM XIP attempt (crashes differently)

* fix(firmware): address PR #397 review feedback
Applies @ruvnet's five review requests on PR #397 (RuView#397 comment
4289417527):
1. **Inline comment on `provision.py` `write_flash`** — ESP-IDF v5.4
bundles esptool 4.10.0 (underscore-only). #391's hyphen swap broke
the documented venv flow; kept the underscore form and added a
three-line comment warning future maintainers not to "re-fix" it.
2. **Correct `edge_processing.c` sample_rate** (blocking) — changed
hard-coded `20.0f` → `10.0f` at line 718 so
`estimate_bpm_zero_crossing()` matches the MGMT-only CSI rate.
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.

Users on multi-node ESP32 deployments have been reporting for months
that their provisioned `node_id` reverts to the Kconfig default of `1`
in UDP frames and the `csi_collector` init log, despite boot showing:
nvs_config: NVS override: node_id=4
main: ESP32-S3 CSI Node (ADR-018) - Node ID: 4
csi_collector: CSI collection initialized (node_id=1, channel=11)
See #232, #375, #385, #386, #390. The root memory-corruption path for
the `g_nvs_config.node_id` byte has not been definitively isolated
(does not reproduce on my attached ESP32-S3 running current source
and the v0.6.0 release binary), but the UDP frame header can be made
tamper-proof regardless:
1. `csi_collector_init()` now captures `g_nvs_config.node_id` into a
module-local `static uint8_t s_node_id` at init time.
2. `csi_serialize_frame()` reads `buf[4]` from `s_node_id`, not from
the global - so any later corruption of `g_nvs_config` cannot
affect outgoing CSI frames.
3. All other consumers (`edge_processing.c` x3, `wasm_runtime.c`,
`display_ui.c`, `main.c swarm_bridge_init`) now go through a new
`csi_collector_get_node_id()` accessor instead of reading the
global directly.
4. A canary at end-of-init logs `WARN` if `g_nvs_config.node_id`
already diverges from the captured value - this will pinpoint
the corruption path if it happens on a user's device.
Hardware validation on attached ESP32-S3 (COM8):
- NVS loads node_id=2
- Boot log: `main: ... Node ID: 2`
- NEW log: `csi_collector: Captured node_id=2 at init (defensive
copy for #232/#375/#385/#390)`
- Init log: `csi_collector: CSI collection initialized (node_id=2)`
- UDP frame byte[4] = 2 (verified via socket sniffer, 15/15 packets)
This is defense in depth - it shields the UDP frame from whatever
upstream bug is clobbering the struct. When a user hits the original
bug, the canary WARN will help isolate the root cause.

CONFIG_CSI_NODE_ID (compile-time, always 1) was hardcoded in 6
places: CSI frame serialization, compressed frames, vitals packets,
WASM output packets, and display UI. NVS provisioning wrote the
correct node_id but it was never used at runtime.
Fixed all occurrences to use g_nvs_config.node_id:
- csi_collector.c: frame header + log message
- edge_processing.c: compressed frame + vitals packet
- wasm_runtime.c: WASM output packet
- display_ui.c: system info display
This means --node-id 0/1/2 provisioning now actually works for
multi-node mesh deployments.
Closes#279
Co-Authored-By: claude-flow <ruv@ruv.net>
- provision.py: add --channel (CSI channel override) and --filter-mac
(AA:BB:CC:DD:EE:FF format) arguments with validation
- nvs_config: add csi_channel, filter_mac[6], filter_mac_set fields;
read from NVS on boot
- csi_collector: auto-detect AP channel when no NVS override is set;
filter CSI frames by source MAC when filter_mac is configured
- ADR-060 documents the design and rationale
Fixes#247, fixes#229
The committed sdkconfig had CONFIG_ESP_WIFI_CSI_ENABLED disabled, causing
all builds to crash at runtime with "CSI not enabled in menuconfig".
Root cause: sdkconfig.defaults.template existed but ESP-IDF only reads
sdkconfig.defaults (no .template suffix).
Fixes:
- Add sdkconfig.defaults with CONFIG_ESP_WIFI_CSI_ENABLED=y
- Add #error compile guard in csi_collector.c to prevent recurrence
- Fix NVS encryption default (requires eFuse, breaks clean builds)
Verified: Docker build + flash to ESP32-S3 + CSI callbacks confirmed.
Closes#241
Relates to #223, #238, #234, #210, #190
Co-Authored-By: claude-flow <ruv@ruv.net>
The CSI callback fires for every WiFi frame in promiscuous mode
(100-500+ fps). Each call invoked sendto() synchronously, exhausting
lwIP packet buffers (errno 12 = ENOMEM). The rapid-fire failures
cascaded into a LoadProhibited guru meditation crash.
Two fixes:
1. csi_collector.c: Rate-limit UDP sends to 50 Hz (20ms interval).
CSI frames arriving between sends are dropped — the sensing
pipeline only needs 20-50 Hz.
2. stream_sender.c: When sendto fails with ENOMEM, suppress further
sends for 100ms to let lwIP reclaim buffers. Logs the backoff
event and resumes automatically.
Closes#127
* feat: add MAC address filter for ESP32 CSI collection
In multi-AP environments, CSI frames from different access points get
mixed together, corrupting the sensing signal. Add transmitter MAC
filtering so only frames from a specified AP are processed.
Implementation:
- csi_collector: filter in wifi_csi_callback by comparing info->mac
against configured MAC; log transmitter MAC in periodic debug output
- csi_collector_set_filter_mac(): runtime API to enable/disable filter
- Kconfig: CSI_FILTER_MAC option (format "AA:BB:CC:DD:EE:FF")
- NVS: "filter_mac" 6-byte blob overrides Kconfig at runtime
- nvs_config: parse Kconfig MAC string at boot, load NVS override
- main: apply filter from config after csi_collector_init()
When no filter is configured (default), behavior is unchanged —
all transmitter MACs are accepted for backward compatibility.
