The first version of my ESP32 Portable WiFi Analyzer is complete.

The device can:

• Scan Wi-Fi networks
• Display signal strength
• Show channels
• Detect security type
• Switch between networks

Future improvements:

• Signal graphs
• Web interface

I added a button for browsing detected Wi-Fi networks.

The ESP32-S2 Mini built-in BOOT button is used as the navigation button.

I also added button debounce to prevent multiple inputs from a single press. I improved the project structure and documentation.

Changes:

• Added GitHub repository structure
• Added README
• Added MIT license
• Improved code comments
• Added hardware documentation

The project is now easier for others to build.

Today I created the first working version of the Wi-Fi analyzer.

The ESP32-S2 Mini can now scan nearby networks and display them on the OLED screen.

I connected:

• ESP32-S2 Mini
• SSD1306 OLED display

The biggest challenge was getting the OLED communication working correctly.

I started a new hardware project for Hack Club Stardance.

The goal is to create a small portable Wi-Fi analyzer using an ESP32-S2 Mini and an OLED display.

The device should be able to scan nearby Wi-Fi networks and display:

• SSID
• signal strength
• Wi-Fi channel
• security type

I chose this project because I am interested in electronics, ESP32 development and wireless communication.
