Hi All!
Could somebody explain how to create GSM tracker application which will send data to web server with Symbian C++. I found example for display current position on the phone but i could not understand how to send this data to web server which will store position in local db and show position in real time with google maps.

Hi asparov,

At wep server side: for example Create small php script which takes your coordinates as parameters. Also check those parameters at the server side and you can do at the server side what ever you like to do with that information.

At mobile side: create HTTP connection to your server and just call your server script...

Eg. your application calls like this server side www.yourserver.net/index.php?parameters

and server just returns message "OK" or "FAILED".

You can refer HTTP Client Example, which contains the HttpClientEngine Class you can use it directly in your application to post data to server.

Thank you, i got successfull results but at now i have one more question.

I have the following code to get altitude, latitude and longitude:

PHP Code:

iClient->CancelTransaction();

            
            iView->ResetL();
            TBuf8<KDefaultBufferSize> uri8;
            
            TPosition pos;
            iPositionInfo.GetPosition(pos);
            TRealFormat realFormat(16,13);
            realFormat.iType = KRealFormatFixed | KDoNotUseTriads;
            
            TRealFormat altitudeFormat(16,12);
            altitudeFormat.iType = KRealFormatFixed | KDoNotUseTriads;
            
            uri8.Append(pos.HorizontalAccuracy());
            //uri8.AppendNum(pos.Time());
            uri8.Append(pos.VerticalAccuracy());
            uri8.Append(KUrl);
            uri8.Append(KLongitude);
            uri8.AppendNum(pos.Longitude(), realFormat);
            uri8.Append(KDataSeparator);
            uri8.Append(KAltitude);
            uri8.AppendNum(pos.Altitude(), altitudeFormat);
            uri8.Append(KDataSeparator);
            uri8.Append(KLatitude);
            uri8.AppendNum(pos.Latitude(), realFormat);
            
            // Start transaction
            iClient->IssueHTTPGetL(uri8); 


But i need to get more parameters such as gps status,date,time, longitude letter (for example E for east), latitude letter, speed,gps heading, satellites, gps checksum.

Please advise how can i get them. It would be very nice if you show me example.

Thanks!
