schizophrene:
-
Ok, je me prends la tête depuis hier pour pas grand chose: je ne suis pas en WPA2, mais en WPA simple! Du coup, ça fonctionne beaucoup mieux bien configuré 
-
Par contre, je perds assez vite la connexion, sans pouvoir la retrouver, même en resetant 
bonjour
- ceci explique cela
- Attention, c'est peut être du à l'ouverture de l'IDE (reset par ouverture du FTDI) , a tu essayé une alim complétement indépendante ?
j'ai été un peu surpris par le reset, mais la connexion revient ensuite seule en 30/40" (livebox orange chez moi)
Je n'ai pas joué encore beaucoup plus , mais petit ajout au sketch indiqué par Al1fch (toggle 3 led + recup ANA0 )
c'est pas beau , mais c'est fonctionnel !
A0 sur GND = 0
A0 sur +5V = 1023
A0 sur 3.3V legere fluctuation = 705/707

) sur où et comment bien installer les librairies
mon routeur (un netgear WNR2000) est en "WPA-PSK [TKIP] + WPA2-PSK [AES]" en mode 802.11b,g,n est la shield ce connecte sans probléme.
