Implement the hardware and firmware portions of RuvSense (ADR-029) and RuView (ADR-031) for multistatic WiFi sensing: Rust (wifi-densepose-hardware): - TdmSchedule: uniform slot assignments with configurable cycle period, guard intervals, and processing window (default 4-node 20 Hz) - TdmCoordinator: manages sensing cycles, tracks per-slot completion, cumulative clock drift compensation (±10 ppm over 50 ms = 0.5 us) - SyncBeacon: 16-byte wire format for cycle synchronization with drift correction offsets - TdmSlotCompleted event for aggregator notification - 18 unit tests + 4 doctests, all passing Firmware (C, ESP32): - Channel-hop table in csi_collector.c (s_hop_channels, configurable via csi_collector_set_hop_table) - Timer-driven channel hopping via esp_timer at dwell intervals - NDP frame injection stub via esp_wifi_80211_tx() - Backward-compatible: hop_count=1 disables hopping entirely - NVS config extension: hop_count, chan_list, dwell_ms, tdm_slot, tdm_node_count with bounds validation and Kconfig fallback defaults Co-Authored-By: claude-flow <ruv@ruv.net>
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),
}
