Problem in reading cell broadcast message(nokia 3660)

hi
I am trying to retrieve the cell broadcast message containing the location string. I am including etelagsm.h and linking with gsmadv.lib. I tried both the cases: 1) Instantiating RAdvGsmSmsMessaging, and calling ReadCbsMessage(lStatus, lMsg). 2) Invoking statically, RAdvGsmSmsMessaging::ReadCbsMessage(lStatus, lMsg) But none of these methods work. The code compiles fine, but both the emulator and Nokia 3660 say "Application Closed" while execution. Actually, there seems to be a problem with initializing RAdvGsmSmsMessaging, because none of the APIs, e.g RAdvGsmSmsMessaging::GetCbsReceiveMode(lMode) or RAdvGsmSmsMessaging::SetCbsReceiveMode(lMode) execute successfully. Btw, I am using Nokia Series 60 SDK 1.2 Please somebody throw some light on this problem.. -Abhinav Kaushik |

I would like to present a few things that I tried, but were unsuccessful.
I tried using the following sample code from newLC post "Mission Impossible : Getting the Location string".
RTelServer iServer;
RMobilePhone iPhone;
RTelServer::TPhoneInfo iPhoneInfo;
TRequestStatus iReqStatus;
RMobileBroadcastMessaging iBroadcastMsg;
TBuf8<88> iGsmMsgdata;
_LIT(KGsmModuleName, "phonetsy.tsy");
iServer.Connect();
iServer.LoadPhoneModule( KGsmModuleName );
TInt enumphone;
User::LeaveIfError(iServer.EnumeratePhones(enumphone));
if (enumphone < 1) {
User::Leave(KErrNotFound);
}
User::LeaveIfError(iServer.GetPhoneInfo(0, iPhoneInfo));
User::LeaveIfError(iPhone.Open(iServer, iPhoneInfo.iName));
iBroadcastMsg.Open(iPhone);
RMobileBroadcastMessaging::TMobileBroadcastAttributesV1 iAttrInfo;
TPckg<RMobileBroadcastMessaging::TMobileBroadcastAttributesV1> iDes(iAttrInfo);
iBroadcastMsg.ReceiveMessage(iReqStatus,iGsmMsgdata,iDes);
User::WaitForRequest(iReqStatus);
...............

In the Series 60 SDK 1.2, I am unable to find the declaration (header files) and implementation of class RMobileBroadcastMessaging. Please tell me if I am supposed to get the header and lib for RMobileBroadcastMessaging from somewhere.
On thread, "Mission Impossible : Getting the Location string", there was a post saying that for Symbian 6.1 I think etelagsm.h holds the answer. How can that be done. Does it happen using RAdvGsmSmsMessaging? I had posted what I tried in my last comment. Please tell me if I am doing something wrong.

RMobileBroadcastMessaging is in ETelmm.h

No need to panic. I have some thing for all of you.
As far as location name is concerned. I am able to fetch the location. I have done this project before six months and i have tested this stuff for long time.
Here you go.
libs :
etel.lib estlib.lib GSMBAS.LIB etelmm.lib
includes :
<etelbgsm.h>
<etelmm.h>
The code for fetching the location from CBM message
-----------------------------------------------------
TInt enumphone = 1;
//Get Locattion
RTelServer iServer;
RMobilePhone iPhone;
RTelServer::TPhoneInfo iPhoneInfo;
TRequestStatus iReqStatus;
//GSM CBM's length is 88 bytes
TBuf8<256> iGsmMsgdata;
_LIT(KGsmModuleName, "phonetsy.tsy");
//to get other info then location
RBasicGsmPhone phone;
MBasicGsmPhoneNetwork::TCurrentNetworkInfo NetworkInfo;
TBuf<MBasicGsmPhoneNetwork::KLongNetworkNameSize> iLongNwName;
iServer.Connect();
iServer.LoadPhoneModule( KGsmModuleName );
User::LeaveIfError(iServer.EnumeratePhones(enumphone));
if (enumphone < 1) {
User::Leave(KErrNotFound);
}
//Initialise the phone object
User::LeaveIfError(iServer.GetPhoneInfo(0, iPhoneInfo));
//to get other info
User::LeaveIfError(phone.Open(iServer, iPhoneInfo.iName));
CleanupClosePushL(phone);
User::LeaveIfError(phone.GetCurrentNetworkInfo(NetworkInfo));
CleanupStack::PopAndDestroy();
//ends here
// network file
TBuf16<128> bLocStr;
RMobileBroadcastMessaging iBroadcastMsg;
User::LeaveIfError(iPhone.Open(iServer, iPhoneInfo.iName));
iBroadcastMsg.Open(iPhone);
RMobileBroadcastMessaging::TMobileBroadcastAttributesV1 iAttrInfo;
TPckg<RMobileBroadcastMessaging::TMobileBroadcastAttributesV1> iDes(iAttrInfo);
//Wait for the CBM
iBroadcastMsg.ReceiveMessage(iReqStatus,iGsmMsgdata,iDes);
User::WaitForRequest(iReqStatus);
TBuf16<100> bDisplay;
bDisplay.Copy(iGsmMsgdata);
int i;
char locationString[94];
char cbuf;
int char_cnt=0;
unsigned int bb = 0;
unsigned char ur,curr,prev = 0;
for (i=6;i<iGsmMsgdata.Length();i++)
{
cbuf = iGsmMsgdata[i];
unsigned char aa = (1 << (7 - bb%7)) - 1;
ur = cbuf & aa;
ur = (ur << (bb)) | prev;
curr = cbuf & (0xff ^ aa);
curr = curr >> (7 - bb);
prev = curr;
if(ur == 0xd)
{
break;
}
locationString[char_cnt] = ur;
bb = ++bb % 7;
char_cnt++;
if(bb==0)
{
locationString[char_cnt++] = prev;
prev =0;
}
}
locationString[char_cnt] = '\0';
TPtrC8 symbPtr((TText8*)locationString);
bDisplay.Copy(symbPtr);
iPhone.Close();
iServer.UnloadPhoneModule( KGsmModuleName );
iServer.Close();
