[Project] WiFi CSI Radar ADV (V1.43) - Major Performance Update & New UI

[Zeloksa]

Hello M5Stack Community! 👋

I’m back with a major update (V1.43) for the WiFi CSI Radar ADV. Since the last release, I’ve focused on stabilizing the 2D spatial math and pushing the packet capture rate to its absolute theoretical limit on the ESP32-S3.

This firmware turns your Cardputer into a professional-grade Channel State Information (CSI) sensing tool, capable of "seeing" motion through solid obstacles by analyzing radio wave distortions.

🚀 What's New in V1.43:
Enhanced 2D Spatial Profiles: Train the radar to recognize up to 21 unique spatial zones with improved accuracy.

UI Overhaul: New high-contrast HUD elements and real-time PPS (Packets Per Second) counter.

Stability Fixes: Improved ADC filtering for the battery sensor to prevent interference during heavy Wi-Fi injection.

Optimized Dual-Core Architecture: Core 0 now handles 100% of the radio stack, while Core 1 is dedicated to the math engine and UI rendering.

⚙️ Technical Specs:
Capture Rate: 200+ PPS (Physical limit of the 2.4GHz stack).

Detection Engine: Log-normal shadow fading model for distance estimation.

Monitoring: Built-in Web Server for remote data visualization and spatial mapping.

📥 Installation:
The updated firmware is available now in M5Burner:

Open M5Burner.

Search for "Zeloksa" or "WiFi CSI Radar" in the User Custom section.

Burn and enjoy!
