File too large to download using WAP

[nlecomte]

Hello,

I am using the WAP API of the WSP protocol to download a large file (order of 90K) with Nokia 7650.

I have written a code that works for files smaller than 300 bytes, but nothing happens with larger ones (not EMoreData, nothing. I have checked, I have these error messages if I want with my file smaller than 300 bytes).

I use my own gateway, and I have set the packet size to 1000 bytes. With the WAP browser given with the phone, I can download my file, and each packet is of size 1000 bytes (body).


Does someone have an idea of why I could have such a limit?

Thank you,

Nicolas



Thats the code I use, please note that I do not know what to put as headers or body and so I have left them empty.


iRemoteHost.Append(KMyHost); // IP address of the WAP server
iRemotePort = 9201; // port that connects to the gateway

/*Creation of the WAP session (on the mobile) iWSPConnection to
the WAP server iWAPSession (client side of the wap server on the mobile)
at the address iRemoteHost

without using a secure connection (protocol WTLS)*/
err = iWSPConnection.Open(iWAPSession, iRemoteHost ,iRemotePort ,0 ,EIP ,EFalse);
if ( err == KErrNone){

// we define the capabilities of the connection that is going to be used
CCapCodec * Cap = CCapCodec::NewL();
Cap->Reset(); // initialised to the default values
Cap->SetClientSDUSize(90000); // 90 000 bytes => have to use SAR
Cap->SetServerSDUSize(90000); // 90 000 bytes => have to use SAR
// connect to the server using these capabilities
err = iWSPConnection.Connect(ClientHeaders, Cap);
if ( err == KErrNone){
RWAPConn::TMethod Method = RWAPConn::EGet; // we will invoke a GET method
/* We create a transaction through the session iWSPConnection

err = iWSPConnection.CreateTransaction(Method, iURI, iBody, iHeaders, iWSPTrans);
if ( err == KErrNone){
err=iWSPConnection.GetEvent(aEvent,iWSPTrans); // Synchronous call –which can be set as asynchronous- to know when the transaction has been successfully created. It is mandatory for continuing the transaction
do{
err = iWSPTrans.GetData(iBuf, RWSPCOTrans::EResultBody); // The result contained in the body of the transaction is stored in the buffer
if(iBuf.Length()>0){ // we ensure that we have some data
iWFichier.WriteL(iBuf, iBuf.Length()); // and we write it to the destination file
ret= KErrNone;
}else{ret=-2;break;} // an error has occured
}while(err==RWAPConn::EMoreData ); // we repeat this process until we have obtained all the requested data
