I'm trying to send an email using my Arduino and the GoBetwino program. The Arduino code, GoBetwino email settings, GoBetwino command settings and the result can be viewed here : Sending an Email Through GoBetwino - Album on Imgur
As you can see, the email is not sent. The return value is -2 which should indicate a non-existant attachment. The problem is that the attachment exists. Even without attaching the file the return value is -2. Can anyone help me?
