wifi shield ne se connecte pas au réseau

**nad_ii** · 25/05/2015, 21h02

Salut,

j'ai un problème avec mon shield wifi, il détecte les réseaux wifi mais n’arrive pas à s'y connecter

la version du firmware est 1.1.0

j'ai essayé l'exemple du webClient d'Arduino en entrant le bon SSID et le bon mot de passe. le serial.print du "status" me renvoi le chiffre 4 qui signifie WL_CONNECT_FAILED,

Si quelqu'un pourrait me venir en aide !

REMERCIEMENTS...

Bonjour,

Il se peut que tu ne configures pas correctement le type de chiffrement de la clé. Tu peux trouver ce type de chiffrement sur ton routeur wifi dans les pages d'administration ou bien sur ton PC dans les paramètres de connexion du WiFi. Sinon, demande à ton administrateur réseaux.

Pourrais tu poster ton code ici ?

**nad_ii** · 26/05/2015, 17h30

Salut,

le type de chiffrement est WPA(TKIP) passephrase, le code est celui du wifi web Server d'arduino sachant qu'il ditecte mon reseau mais n'yacccede pas. j'ai bien verifié le bon SSID et le pass

Bonjour,

Je ne comprends pas, tu parles de l'essai du code de Webclient pour ensuite donner un code de Webserver.
Quel est le but de ton montage ? Faire un serveur wifi sur ton arduino qui rejoint un réseau WiFi existant ?

**nad_ii** · 26/05/2015, 18h48

désolé j'ai confondu entre les exemples, moi ce que je veut c'est faire un web client pour stocker les données venant de capteur vers une BDD

Donc si tu rajoutes un println(status) avant ton délai de 10 secondes tu obtiens l'erreur WL_CONNECTED_FAIL ?
