csiparser 0.1.0

A Python Package to Parse ESP32 Wi-Fi CSI Data

ESP32 Wi-Fi CSI Python Parser

This is a Python parser for ESP32 Wi-Fi Channel State Information (CSI) based on the ESP32 CSI specification.

This project uses ESP CSI Toolkit created by Hernandez and Bulut.

Installation

Run the following to install:

pip install csiparser

Usage

# Import ESP32 CSI parser
import csiparser

# Parse and filter CSI data
example_csi = (
    csiparser.ESP32("./esp32_dataset/example_csi.csv")
             .filter_by_sig_mode(1)
             .get_csi()
             .remove_null_subcarriers()
             .get_amplitude_from_csi()
             .get_phase_from_csi()
)

# Retrieve example amplitude
example_amplitude = example_csi.amplitude

# Retrieve example phase 
example_phase = example_csi.phase

Further the amplitude and phase information can be plotted to visualize the distortion in amplitude and phase shift as follows:
