Confused using cellular radio module

Archive

I try it years ago, but not success. Now I try again, still bad.
There are several drivers for GHI driver, Seed driver, Byron’s Driver, Progressio’s Driver.
Also, there isn’t existing a Tutorial for this. It is hard to start it.

I review the forums trying a code to start but not success.

    public partial class Program
    {
        // This method is run when the mainboard is powered up or reset.   
        void ProgramStarted()
        {
            /*******************************************************************************************
            Modules added in the Program.gadgeteer designer view are used by typing 
            their name followed by a period, e.g.  button.  or  camera.
            
            Many modules generate useful events. Type +=<tab><tab> to add a handler to an event, e.g.:
                button.ButtonPressed +=<tab><tab>
            
            If you want to do something periodically, use a GT.Timer and handle its Tick event, e.g.:
                GT.Timer timer = new GT.Timer(1000); // every second (1000ms)
                timer.Tick +=<tab><tab>
                timer.Start();
            *******************************************************************************************/


            // Use Debug.Print to show messages in Visual Studio's "Output" window during debugging.
            Debug.Print("Program Started");
            cellularRadio.DebugPrintEnabled = true;
            cellularRadio.PowerOn(40);
            cellularRadio.SendATCommand("AT");
            cellularRadio.SendATCommand("AT+CPIN=0000");
            cellularRadio.SendATCommand("AT+CMGF=1");
            cellularRadio.SmsReceived += new CellularRadio.SmsReceivedHandler(cellularRadio_SmsReceived);
            cellularRadio.SmsRetrieved += new CellularRadio.SmsRetrievedHandler(cellularRadio_SmsRetrieved);
            cellularRadio.ModuleInitialized += new CellularRadio.ModuleInitializedHandler(cellularRadio_ModuleInitialized);
            
        }

       
        void cellularRadio_SmsRetrieved(CellularRadio sender, CellularRadio.Sms message)
        {
            if (message != null)
            {
                Debug.Print("RETRIEVED");
                Debug.Print("FROM: " + message.TelephoneNumber);
                Debug.Print("MSG: " + message.TextMessage);
                Debug.Print("WHEN: " + message.Timestamp);
                Debug.Print("STATUS: " + message.Status);
                Debug.Print("POS:" + message.Index);
            }
        }

        void cellularRadio_ModuleInitialized(CellularRadio sender)
        {
            Debug.Print("MODULE INITIALIZED");
        }

        void cellularRadio_SmsReceived(CellularRadio sender, CellularRadio.Sms message)
        {
            if (message != null)
    {
        Debug.Print("NEW SMS");
        Debug.Print("FROM: " + message.TelephoneNumber);
        Debug.Print("MSG: " + message.TextMessage);
        Debug.Print("WHEN: " + message.Timestamp);
        Debug.Print("STATUS: " + message.Status);
        Debug.Print("POS:" + message.Index);
    }
        }
    }

Thanks, the problem is the pin code.
I disable the pin code check.
Now the SMS receive and send can work now.
Next step is using GPRS part to post data.
I will still study and test.

Let us know how it goes, the cellular module is indeed not working very well for many.

And please post, it looks like your code is pretty well-structured.

The GPRS connection with the cellular module has never been possible to me.

Cheers

The problems is that there are many methods the module provides.
For example,

 cellularRadio.AttachGPRS();
            cellularRadio.ConfigureTCPServer();
            cellularRadio.ConnectTCP();
            cellularRadio.SendTcpData();

But we don’t know what methods we should use,for GPRS and the order for using this method?
Do we use AT command before using this method?

Report:

I test GPRS by follow code , seems has a progress but still has error.
Anyone can point me what’s wrong for my steps or code.
Thank you very much.

The other post is that I face a problem for using Byron’s driver.
Thanks Byron, he is help me.

And the post here,is that I was trying to use GHI’s driver to do the GPRS steps by steps.
