Hi.
I try the sms example with some problems...

If i try to send directtly AT+CPMS="SM","SM","SM" from terminal it's ok, it show 7,20,7,20...
If i read a sms with AT+CMGR=2 it response with the message body...

When i try with arduino in ard mode in the Monitor i see 325 Message and when read a message with CMGR it stop.....what is the problem??

Thanks!!

I try some expermeriment with the code....the problem of the stop is when i not print the output...

Code:

  Serial.println("AT+CPMS=\"SM\",\"SM\",\"SM\"");
  Serial.flush();
  for (x=0;x< 255;x++){            
    data[x]='\0';                                       
  } 

  x=0;
  do{
      while(Serial.available()==0);
      data[x]=Serial.read();  
      [color=#FF0000]Serial.println(data[x]); [/color] //with this line work.....           
      x++;       
  }while(!(data[x-1]=='K'&&data[x-2]=='O'));

I don't understand why???

Hello valerioweb:

The problem is fixed changing this line of code

Code:

n_sms=((data[32]-0x30)*10)+(data[33]-0x30);

by this others

Code:

        x=0;
        do{
            x++;
        }while (data[x] != ' ');

        x++;
        n_sms=0;
        do{
            n_sms*=10;
            n_sms=n_sms + (data[x]-0x30);
            x++;
        }while (data[x] != ',');

The code stops readin the SMS because there isn't a SMS in the index 325.

Regards
