## ⚙️ Fonctionnement - **Premier démarrage** : pas de SSID enregistré → le module crée un AP `XIAO_Config`. - **Page web** : accessible via l’IP du point d’accès (souvent `192.168.4.1`). - **Sauvegarde** : SSID et mot de passe sont stockés dans `Preferences`. - **Redémarrage** : le module tente de se connecter au Wi Fi enregistré. - **Fallback** : si la connexion échoue, retour en mode AP pour reconfigurer.
- **Mode AP (point d’accès)** au démarrage → permet de configurer les paramètres Wi Fi via une page web. - **Sauvegarde des paramètres** (SSID, mot de passe, etc.) dans la mémoire non volatile (Preferences). - **Redémarrage automatique en mode station** → le XIAO se connecte au réseau configuré. - **Fallback** : si la connexion échoue, il revient en mode AP pour reconfigurer.
