Real-time Wi-Fi Channel State Information (CSI) visualization built for the M5Stack CoreS3 SE.
This lightweight terminal user interface (TUI) is strictly optimized for the M5Stack CoreS3 SE IoT Controller. Its compact form factor, physical touch interface, and robust ESP32 processing power make it the ultimate vessel for a portable spectral analyzer.
|
Upon powering up the CoreS3 SE, the system initiates the neon-styled retro TUI. Designed for high-visibility in field operations, the interface carries zero bloat. Tap START VISUALIZING to initialize the radio and memory allocation. |

Adapt to your environment by selecting the appropriate connection topology:
|
|
|
Visualize the raw volume of data moving through the airwaves. This real-time graph maps amplitude across subcarriers, instantly highlighting network congestion, heavy data transfers, or high-bandwidth anomalies in your immediate vicinity. |
|
|
Strip away the noise and look at the physical properties of the signal. By tracking the unwrapped phase offset, you can detect microscopic environmental shifts, physical movement within a room, and complex multipath fading effects. |
|
|
A scrolling matrix mapping amplitude history over time into a density color-map. This view acts as a "heat map" for the air, allowing you to track fleeting signal bursts, frequency hopping, and persistent noise floors as they happen across the spectrum. |
|
|
Track the aggregate power of your selected target. This graph plots signal strength (in dBm) over time. It utilizes an Exponential Moving Average (EMA) to smooth out erratic environmental spikes, providing a clear directional trend for tracking. |
|
|
Don't lose your scan data. Before deployment, the TUI prompts you to initialize the onboard SD card. Capturing raw CSI data as CSV files allows you to extract the payload later for advanced filtering and machine-learning analysis on your main machine. |
|
|
A built-in tactical manual. If you need a quick refresher on module definitions or the color-coded intensity spectrum (e.g., matching 'Dark Indigo' to 65% Intensity), the reference guide is instantly accessible without interrupting your workflow. |
