title: efcom v1.2 shield not communicating (Arduino & GSM/GPRS)
body: <p>I have it connected as described in the official website <a href="http://www.elecfreaks.com/wiki/index.php?title=EFCom_GPRS/GSM_Shield" rel="nofollow">ELECFREAKS EFCOM V1.2</a></p>
  
  <p>I use Arduino 1.0.5, upload the example code in the link above, turning the SIM900 on with the pushbutton, it has connection to the operator (indicated by the short flash every 3 second) and it seems fine.. im just not able to send AT commands, and it seems like im not getting anything back to the computer either...</p>
  
  <p>I see that it is default 19200 8N1, i try to send commands in Serial monitor in Arduino 1.0.5, and SSCOM3.2 (linked from page above) and I disable auto-bauding mode, using "AT+IPR=19200"..   </p>

    <p>I use Arduino 1.0.5<br>
    Arduino UNO R3<br>
    Efcom V1.2 (SIM900 GSM / GPRS)<br>
    Charger -> 9v - 1A </p>
    
    <p>S_RX (GRPS) -> PIN 3 (Arduino)<br>
    S_TX (GPRS) -> PIN 2 (Arduino)<br>
    baud = 19200  </p>

  <pre><code>//ARDUINO CODE
  # include &lt;SoftwareSerial.h&gt;
  
  SoftwareSerial mySerial (2, 3);
  
  void setup () {
     mySerial.begin (19200) / / the GPRS baud rate
     Serial.begin (19200) / / the GPRS baud rate
     Serial.println ("begin .....");
  }
  
  void loop () {
     if (mySerial.available ())
       Serial.write (mySerial.read ());
     if (Serial.available ())
       mySerial.write (Serial.read ());
  }
  </code></pre>
  
  <p>All works out until i should try the communication via the serial port. It's just no respond.. </p>
