ESP32 Easy WiFi Config is a MicroPython project designed to simplify the process of connecting your ESP32 board to a WiFi network. This project enables a web-based interface that allows users to scan for available WiFi networks, enter credentials, and store them on the device. The configuration mode can be triggered using a GPIO pin, making it easy to switch between normal operation and configuration mode.
- Configuration Mode: Trigger configuration mode via a GPIO pin.
- Network Scanning: Scans and displays available WiFi networks.
- Easy WiFi Configuration: Simple web interface to select and connect to WiFi networks.
- Secure Storage: Stores WiFi credentials in a JSON file on the device.
- Automatic Connection: Attempts to connect to the stored WiFi network on boot.
- Fallback to Configuration Mode: If connection fails, automatically starts the web interface for reconfiguration.
- Configuration Mode: On device boot, if the defined GPIO pin is high, the device enters configuration mode, starting a web server.
- Web Interface: Connect to the device's access point (ESP32_Config) and open a web browser to the device's IP 192.168.4.1 to access the configuration page.
- Network Selection: Select a WiFi network from the list, enter the password, and save the configuration.
- Connection: The device will attempt to connect to the selected network. If successful, it will run the main application code; otherwise, it will re-enter configuration mode.
