SmartProv v2.1.3

SmartProv v2.1.3 – Initial Stable Release

SmartProv is a captive-portal Wi-Fi provisioning library for ESP32 and ESP8266 designed to eliminate hardcoded Wi-Fi credentials in embedded/IoT deployments.

On first boot, the device automatically enters setup mode, launches an Access Point, and serves a mobile-friendly captive portal where users can configure Wi-Fi credentials. Credentials are securely stored in flash and reused on future boots.
