Hi
I can use another sim card from a Portuguese network (TMN) to send and receive sms and internet?
I use arduino uno r3 and the last Arduino GSM Shield

[Reply #1 on:]

Hi Joaoj,
yes, the GSM shield works with any sim card enabled to send and receive sms or internet. Let us know if you need other support.

Best regards,
Alberto

Thanks.

when I load the example "testemodem" shows me this:
Starting modem test...modem.begin() succeeded
Checking IMEI...Modem's IMEI:
359231038082408
Resetting modem...Modem is functoning properly

when I load the example "gsmscannetworks"  or other shows me this:
"GSM networks scanner"
and do not go to the next step


when I load the example "pinmanagement" shows me this:
Change PIN example

PIN & PUK locked. Use PIN2/PUK2 in a mobile phone.

Note: the simcard has no pin code and  works well on a mobile phone...

Hello, may you execute the TestGPRS example, changing the line
GSM gsmAccess();
for
GSM gsmAccess(true);

Execute the tool with the Monitor Serial open, and copy here the dumped codes. So we can see if there is any connectivity issue.

Thanks.

Good news are, your shield is connecting OK to the network and you can procceed with the examples.

Only bad thing is that gsmscannetworks is not running properly in your environment... Following your post, it looks like gsmAccess.begin() is not giving an answer in gsmscannetworks. The funny thing is that gsmAccess.begin() runs OK in TestGPRS.

I've found something that can be improved in the network scanning code but your sketch doesn't even reach that point...

I'll ask you a couple of things:
- Have you left gsmscannetworks running for at least a couple of minutes?
- May you copy a dump of gsmscannetworks?

Have you tried any example?

Hi 
incredible! Now everything works and no longer need to put the "true" code in "GSM gsmAccess()"

gsmscannetworks dump:
--------------------------------
GSM networks scanner
Modem IMEI: 359231038082408
Scanning available networks. May take some seconds.
> TMN
> OPTIMUS

Current carrier: TMN
Signal Strength: 16 [0-31]
Scanning available networks. May take some seconds.
> TMN
----------------------------------------------------------
thanks

Hijacking this thread, guess it's ok.

Put a swisscom sim with pin into my gsm shield.
Changed the TestGPRS example and changed the code to GSM gsmAccess(true).

Dump is

Code:

OK

it then asks me for the apn and I enter gprs.swisscom.ch (found on http://forums.pinstack.com/f24/tcp_apn_wap_gateway_port_carrier_settings-360/ via http://arduino.cc/en/Guide/ArduinoGSMShield)

But then it stays on

Code:

Enter your APN:

for ever...

[Reply #8 on:]

looks like it's a problem with the serial interface.

because this code works with my swisscom settings:

Code:

// include the GSM library
#include <GSM.h>

// PIN number if necessary
#define PINNUMBER "7779"

// APN information obrained from your network provider
#define GPRS_APN       "gprs.swisscom.ch" // replace with your GPRS APN
#define GPRS_LOGIN     ""                  // replace with your GPRS login
#define GPRS_PASSWORD  "gprs"             // replace with your GPRS password

// initialize the library instances
GSMClient client;
GPRS gprs;
GSM gsmAccess;

// This example downloads the URL "http://arduino.cc/latest.txt"

char server[] = "arduino.cc"; // the base URL
char path[] = "/latest.txt"; // the path
int port = 80; // the port, 80 for HTTP

void setup()
{
  // initialize serial communications
  Serial.begin(9600);
  Serial.println("Starting Arduino web client.");
  // connection state
  boolean notConnected = true;

  // Start GSM shield
  // pass the PIN of your SIM as a parameter of gsmAccess.begin()
  while(notConnected)
  {
    if((gsmAccess.begin(PINNUMBER)==GSM_READY) &
        (gprs.attachGPRS(GPRS_APN, GPRS_LOGIN, GPRS_PASSWORD)==GPRS_READY))
      notConnected = false;
    else
    {
      Serial.println("Not connected");
      delay(1000);
    }
  }

  Serial.println("connecting...");

  // if you get a connection, report back via serial:
  if (client.connect(server, port))
  {
    Serial.println("connected");
    // Make a HTTP request:
    client.print("GET ");
    client.print(path);
    client.println(" HTTP/1.0");
    client.println();
  }
  else
  {
    // if you didn't get a connection to the server:
    Serial.println("connection failed");
  }
}

void loop()
{
  // if there are incoming bytes available
  // from the server, read them and print them:
  if (client.available())
  {
    char c = client.read();
    Serial.print(c);
  }

  // if the server's disconnected, stop the client:
  if (!client.available() && !client.connected())
  {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();

    // do nothing forevermore:
    for(;;)
      ;
  }
}

Have you configured the Serial Monitor to add both NL&CR?

Thanks.

But I don't understand, vhat you've done? I have the same symptoms as you had, what to do?

[Reply #11 on:]

Hi
when I changed  the line:

GSM gsmAccess();
for
GSM gsmAccess(true);

in serial monitor asked for this information:
----------------------------
Enter your APN: internet
Now, enter your login: tmn
Finally, enter your password:
-------------------
after entering data work perfectly for ever...
