[Update] Wi-Fi & BLE Radar ADV (V2.0) for Cardputer - Dual-Band Tactical Scanner
-

Hello M5Stack Community! 📡
I am excited to announce a massive V2.0 update to my tracking tool for the Cardputer. What started as a high-speed Wi-Fi scanner is now the Wi-Fi & BLE Radar ADV (V2.0).
This update transforms the Cardputer into a full-fledged dual-band tactical direction-finding tool. I've added a completely independent Bluetooth Low Energy (BLE) engine, asynchronous background scanning, and cyber-security analytics to bypass modern MAC randomization.
⚡ V2.0 Technical Highlights:
- Dual-Band Radar (Wi-Fi & BLE): Independent tracking engines with strict antenna sharing logic to prevent radio coexistence interference.
- Anti-Tracking Bypass & OUI DB: Modern phones use randomized MAC addresses to hide. The V2.0 engine parses IEEE address types on the fly to expose randomized targets and uses an embedded OUI database to instantly resolve vendors (Apple, Xiaomi, Garmin, Huami, etc.) directly on the screen.
- Asynchronous TDM Scanning: The new Split-Screen Device List continuously multiplexes between Wi-Fi and BLE in the background (3-second intervals). It can track up to 1000 devices per protocol in real-time without freezing the UI.
- Visual Stability Engine: Added UI Throttling. While data is captured at maximum speed, visual sorting updates every 1.2s to prevent "text shaking" in highly crowded RF environments.
- Active Probing & Log-Normal Math: Still features the aggressive 40 FPS Wi-Fi probing from V1.5, combined with real-time signal attenuation math to estimate physical distance (in meters).
- Security Tags: Open Wi-Fi networks are now explicitly flagged with a yellow [OPEN] tag (turns red when targeted) so you can spot unsecured networks instantly.
⚠️ Important Hardware Limitation:
The ESP32-S3 chip inside the Cardputer supports BLE only, not Bluetooth Classic. It will easily track modern smartphones, smartwatches, and IoT beacons, but it will not see legacy devices like old headphones, car stereos, or PS3/PS4 controllers.📥 How to Install:
Available right now in M5Burner:- Open M5Burner.
- Search for "Zeloksa" or "WiFi & BLE Radar ADV".
- Download version V2.0 and burn to your Cardputer.
