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 CsiFrame into the CsiData format expected by the detection pipeline (ADR-018 Layer 3).
No mock data -- Parsers either parse real bytes or return explicit ParseError values. 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),
}
