GSRS/GSM problem

hello,

i using gprs shield v1.0 crowduino v1.0 , wish send sms using it. link shield :
http://www.elecrow.com/arduino-compatiable-c-109/shield-c-109_110/gprsgsm-shield-for-arduino-p-325.html , , link crowduino http://www.elecrow.com/arduino-compatiable-c-109/micro-controller-c-109_117/crowduino-with-atmega-328-p-338.html .it has arduino uno pin layout , dimensions inherits duemilanuve features + has bee shield (i dont know it).

i using arduino ide 1.05
i use latest gsm library 3.05 https://code.google.com/p/gsm-shield-arduino/downloads/list
the status led blinks @ rate of 64ms on/3000ms off, no pin sim card. romania , cosmote network shield should cover network frequency, right?

i have tested crowduino examples , works fine. cant seem shield anything.
with gsmscannetwork example code get: gsm networks scanner, thats , waited while , nothing happened.

code: [select]


// libraries
#include <gsm.h>

// pin number
#define pinnumber ""

// initialize library instance
gsm gsmaccess(true);     // include 'true' parameter enable debugging
gsmscanner scannernetworks;
gsmmodem modemtest;

// save data variables
string imei = "";

// serial monitor result messages
string errortext = "error";

void setup()
{
  // initialize serial communications , wait port open:
  serial.begin(9600);
  while (!serial) {
    ; // wait serial port connect. needed leonardo only
  }

  serial.println("gsm networks scanner");
  scannernetworks.begin();
 
  // connection state
  boolean notconnected = true;
 
  // start gsm shield
  // if sim has pin, pass parameter of begin() in quotes
  while(notconnected)
  {
    if(gsmaccess.begin(pinnumber)==gsm_ready)
      notconnected = false;
    else
    {
      serial.println("not connected");
      delay(1000);
    }
  }
 
  // modem parameters
  // imei, modem unique identifier
  serial.print("modem imei: ");
  imei = modemtest.getimei();
  imei.replace("\n","");
  if(imei != null)
    serial.println(imei);
}

void loop()
{
  // scan existing networks, displays list of networks
  serial.println("scanning available networks. may take seconds.");
  serial.println(scannernetworks.readnetworks());
 
    // connected carrier
  serial.print("current carrier: ");
  serial.println(scannernetworks.getcurrentcarrier());
   
  // returns strength , ber
  // signal strength in 0-31 scale. 31 means power > 51dbm
  // ber bit error rate. 0-7 scale. 99=not detectable
  serial.print("signal strength: ");
  serial.print(scannernetworks.getsignalstrength());
  serial.println(" [0-31]");

}


with sendsms example on serial monitor: sms messages sender. nothing else.
i need certain

use code have try. , if there problems can contact techsupport[at]elecrow.com.
