Station Profiles
This example gives WiFiManager a small application-owned EEPROM store. The portal accepts a required primary Wi-Fi network and an optional fallback, verifies a submitted network before saving it, then remembers the last successful choice across restarts.
On a blank board, connect to WiFiManager Profiles with password example-pass and open http://192.168.4.1/. Enter a primary network and, if useful, one fallback. After a successful connection, restart the board to confirm that it tries the saved profiles before reopening the portal.
StoredProfiles is intentionally simple so the ownership boundary is visible. A production application should add its own record versioning and integrity protection around the application’s complete configuration; WiFiManager only owns network-selection policy.
See Station profiles, primary and fallback Wi-Fi, and the shared example guide.
