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.
RTL8720F radar simulator (ADR-263/264)
Until Realtek hardware and the radar report SDK arrive, the Rust-only simulator exercises the same
versioned CFR/Range-FFT wire codec used by the future device adapter. Every frame is marked
SYNTHETIC.
cargo run -p wifi-densepose-hardware --bin rtl8720f-sim -- `
--frames 100 --seed 0x8720f123456789ab `
--output rtl8720f-synthetic.rtr
Add --udp 127.0.0.1:5005 --realtime to stream one ADR-264 frame per UDP datagram. Replay files
contain a little-endian u32 frame length followed by the encoded frame.
MediaTek Filogic CSI simulator (ADR-266/267)
The Rust-only simulator models bounded MIMO CSI for MT7981/MT7976,
MT7986/MT7975, and MT7988/MT7996 profiles without claiming an undocumented
MediaTek firmware ABI. Every frame is marked SYNTHETIC.
cargo run -p wifi-densepose-hardware --bin mediatek-csi-sim -- `
--profile mt7981 --frames 100 --output mediatek-synthetic.mtc
Add --udp 127.0.0.1:5005 --realtime to stream one CRC-protected ADR-267
frame per UDP datagram. Physical support remains gated on a documented mt76
or MediaTek firmware channel-estimate export.
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),
}
