  • I have an Arduino project and I need to send multiple SMS.
    I can only send one.
    After the first, messages are
    + SIND answer: 11
    + SIND: 3
    + SIND: 4
    But then I can not send more and the answer are
    + CME ERROR: 4
    + CME ERROR: 4
    I’ve waited up to 1 minute and more but doesn´t works.
    What do I do?
    Is this shield to send only one message?

  • Bueno, ya he resuelto mi anterior problema.
    Ahora tengo otro: solamente puedo enviar 1 mensaje de texto.
    Si mando otro después, no sale.
    ¿Qué se hace ahora?

  • We just bought this shield for our company and it does not work.
    We have used the example program with a Arduino Arduino UNO and a MEGA 2560, following the explanation given in: http://tronixstuff.wordpress.com/2011/01/19/tutorial-arduino-and-gsm-cellular-part -one /
    and we get a series of incomprehensible characters. We tested all available transmission rates and it´s the same.
    We do not know what to do.
    We need a solution.

No public wish lists :(
