Problème shield gsm arduino
Bonjour,
Je suis en Terminal STI2D et je suis actuellement en train de faire un projet dans lequel je dois utiliser un shield gsm (http://www.elecfreaks.com/estore/gpr...shd-efcom.html) avec un arduino mega.
Pour le faire fonctionner j'ai donc placer le shield sur l'arduino puis relier la broche D2 et D3 du shield au port 50 et 51 de l'arduino pour la communication Rx et Tx.
Le problème que je rencontre est que le shield ne parvient pas à envoyer des sms lorsque on utilise un code, en effet la fonction retourne "erreur" (le code utilisé est l'exemple de la bibliothèque fournit modifié pour convenir au port de communication) mais il y parvient lorsque l'on utilise un logiciel utilisant les commandes AT , j'ai du modifier la bibliothèque fournit car cette dernière n'était pas à jour avec les dernière version de l'IDE.
Merci.
Voici le code exemple utilisé :
