Audit of every ADR-018 consumer against live C6 HE20 frames (532B/256-bin): - sensing-server + CLI calibrate parsers read n_subcarriers from one byte (256 decoded as 0) with stale seq/rssi offsets (rssi always 0 — latent, pre-existing, confirmed vs firmware csi_collector.c). Fixed to the real ADR-018 layout; n_subcarriers u8->u16; byte 18 surfaced as typed PpduType. - sensing-server probe buffer 256B -> 2048B (532B datagram errored on Windows) - per-node grid gate: lock densest (n_subcarriers, ppdu_type) grid, re-warm on upgrade, skip sparser minority frames — HT-64 never mixes into an HE-256 baseline window - hardware parser: HE-aware bandwidth classification (256-FFT HE20 = 20MHz, was Bw160); PpduType/Adr018Flags re-exported - verbatim live frames (532B HE-SU, 148B HT) embedded as regression fixtures - archive python parser: bandwidth heuristic mirror fix Live-validated: calibrate --tier he20 consumed 600x 256-bin frames into an ADR-135 He20 baseline (242 tones) skipping 94 HT frames; sensing-server shows node 12 active with real RSSI (-40dBm). 765 tests green across the three crates; workspace check clean; Python proof PASS.

wifi-densepose-hardware
Hardware interface abstractions for WiFi CSI sensors (ESP32, Intel 5300, Atheros).
Overview
wifi-densepose-hardware provides platform-agnostic parsers for WiFi CSI data from multiple
hardware sources. All parsing operates on byte buffers with no C FFI or hardware dependencies at
compile time, making the crate fully portable and deterministic -- the same bytes in always produce
the same parsed output.
Features
- ESP32 binary parser -- Parses ADR-018 binary CSI frames streamed over UDP from ESP32 and ESP32-S3 devices.
- UDP aggregator -- Receives and aggregates CSI frames from multiple ESP32 nodes (ADR-018 Layer 2). Provided as a standalone binary.
- Bridge -- Converts hardware
CsiFrameinto theCsiDataformat expected by the detection pipeline (ADR-018 Layer 3). - No mock data -- Parsers either parse real bytes or return explicit
ParseErrorvalues. There are no synthetic fallbacks. - Pure byte-buffer parsing -- No FFI to ESP-IDF or kernel modules. Safe to compile and test on any platform.

Quick Start
use wifi_densepose_hardware::{CsiFrame, Esp32CsiParser, ParseError};
// Parse ESP32 CSI data from raw UDP bytes
let raw_bytes: &[u8] = &[/* ADR-018 binary frame */];
match Esp32CsiParser::parse_frame(raw_bytes) {
Ok((frame, consumed)) => {
println!("Parsed {} subcarriers ({} bytes)",
frame.subcarrier_count(), consumed);
let (amplitudes, phases) = frame.to_amplitude_phase();
// Feed into detection pipeline...
}
Err(ParseError::InsufficientData { needed, got }) => {
eprintln!("Need {} bytes, got {}", needed, got);
}
Err(e) => eprintln!("Parse error: {}", e),
}
