J'ai modifié le fichier d'exemple Adafruit Fona GPS pour montrer l'erreur entre mon emplacement et les emplacements GPS et GSM qu'il recueille. La partie d'erreur que je publie s'affiche correctement, mais les codes AT s'affichent également sur le moniteur série et je n'arrive pas à comprendre comment les supprimer. Le code est ci-dessous et la sortie est en dessous de cela. J'essaie de me débarrasser de tout ce qui n'est pas la ligne commençant par "Erreur GPS ...".Supress AT sortie de code dans le moniteur série sur Adafruit Fona
