ESP32-CaptivePortal-Demo

Arduino sketch showcases the use of DNSServer and ESPAsyncWebServer libraries to implement a captive portal, which is an index.html file stored in ESP32 flash memory via LittleFS library. The example portal includes a form which allows users to enter data which then are received by ESP32.

Sketch and file upload

1. Use Arduino IDE to open ESP32-CaptivePortal.ino file.
2. In Arduino IDE, under Tools tab select ESP32 Sketch Data Upload. It should show a pop-up and then select LittleFS to upload files in the data folder to ESP32 filesystem.
3. Compile and upload .ino sketch to ESP32 in a regular way.

The sketch was modified based on the original captival portal example from the ESPAsyncWebServer library.
