Create AP programically

[ttroy]

Hi,

I'm trying to create an AP programmically using C++.

I can create the AP and it shows on the device in the list of Access Points. But I cannot connect to it until I enter the AP in the settings, go through it and go back out again (i.e. resave it on the device). Once I do this I can connect to it.

If I try to connect to it from my program I get a KErrCouldNotConnect Error, and if I try from the Web Browser it doesn't show up on the list of available AP's, even though it is in range.

The code I use to create it is

	//Creating an access point:
	CApAccessPointItem *wlan = CApAccessPointItem::NewLC();
	CApAccessPointItem *wlanNewItem = CApAccessPointItem::NewLC();

	wlan->SetNamesL(_L("MyAP"));
	wlan->SetBearerTypeL(EApBearerTypeWLAN);
	wlan->WriteTextL(EApWlanNetworkName, _L("MyAP"));

	//Lan network mode should be 1 for infrastructure, 0 for adhoc
	wlan->WriteUint(EApWlanNetworkMode, 1);
			
	//Security mode should be 2 for WEP network 
	wlan->WriteUint(EApWlanSecurityMode, 2);

	// Store it into the CommsDb
	CCommsDatabase *commDb = CCommsDatabase::NewL();
	CleanupStack::PushL(commDb);
	TInt err = commDb->BeginTransaction();
	
	Log(_L("CAP : err after commDb->BeginTransaction"), err);
	CApDataHandler *handler = CApDataHandler::NewLC(*commDb);
	TUint32 newApId = handler->CreateFromDataL(*wlan);
	Log(_L("CAP : newApID afterCreateFromDataL"), newApId);
	TBool val =ETrue;
	handler->UpdateAccessPointDataL(*wlan,val);

	TUint32 newalanid;
	TBuf<50> ibuff;

	handler->AccessPointDataL(newApId,*wlanNewItem); 
	wlanNewItem->ReadUint( EApIapServiceId, newalanid );
	wlanNewItem->ReadTextL( EApWlanNetworkName, ibuff ); 

	Log(_L("CAP : newalanid after REadUint"), newalanid);
	
	CCommsDbTableView* wLanServiceTable = commDb->OpenViewMatchingUintLC( 
	TPtrC( WLAN_SERVICE ), TPtrC( WLAN_SERVICE_ID ), newalanid );

	TInt errorCode = wLanServiceTable->GotoFirstRecord();
	CreatedAccessPointID = newalanid;
		
	if ( errorCode == KErrNone )
		 {
		 wLanServiceTable->UpdateRecord();
		 Log(_L("CAP : wLanServiceTable->UpdateRecord()"));
		 }
	else
		 {
			TUint32 dummyUid( 0 );
			User::LeaveIfError( wLanServiceTable->InsertRecord( dummyUid ) );
			// Save link to LAN service
			wLanServiceTable->WriteUintL( TPtrC( WLAN_SERVICE_ID ), newApId );
			Log(_L("CAP : wLanServiceTable->InsertRecord"), dummyUid);
			Log(_L("CAP : newAPId after saving link "), newApId);
		 }
		 
	TInt error;

	// Save the format of the key (Hexadecimal or Ascii)
	TUint iKeyFormat = 1;
	TRAP(error, wLanServiceTable->WriteUintL( TPtrC( WLAN_WEP_KEY1_FORMAT ),
	( TUint32& ) iKeyFormat ));
	
	Log(_L("CAP : error after WLAN_WEP_KEY1_FORMAT"), error);

	// Save the securitymode
	TUint iSecurityMode = 2;
	TRAP(error, wLanServiceTable->WriteUintL( TPtrC( WLAN_SECURITY_MODE ),
	( TUint32& ) iSecurityMode ));
	Log(_L("CAP : error after WLAN_SECURITY_MODE"), error);

	//index of the WEP Key in use
	TUint iKeyIndex = 0;
	TRAP(error, wLanServiceTable->WriteUintL( TPtrC( WLAN_WEP_INDEX ),
	( TUint32& ) iKeyIndex ));
	Log(_L("CAP : error after WLAN_WEP_INDEX"), error);

	//Type of authentication 0 = Open, 1 = Shared
	TUint iAuthentication = 0;
	TRAP(error,wLanServiceTable->WriteUintL( TPtrC( WLAN_AUTHENTICATION_MODE ),
	( TUint32& )iAuthentication ));
	Log(_L("CAP : error after WLAN_AUTHENTICATION_MODE"), error);
	
	 TBuf8<128> keyData;
	 keyData.Copy(_L("1234567890"));
	TRAP(error,wLanServiceTable->WriteTextL( TPtrC( WLAN_WEP_KEY1 ), 
	                 keyData));
	Log(_L("CAP : error after WLAN_WEP_KEY1"), error);


	wLanServiceTable->PutRecordChanges();
	err = commDb->CommitTransaction();    	
        // End a transaction. Call after `InsertRecord()` or `UpdateRecord()`.
	CleanupStack::PopAndDestroy(5);

I've also logged err after CommitTransaction and it didn't show any error.



I have created a function to read out the values in the commsDB both after I create it and after I resave it from settings on the device and am able to use it. And they both show the same values.


I must be missing something that activates the AP on the device, but I can't find out what it is from the documentation.

Can anyone see where I'm going wrong?

Have you checked the examples in the Wiki? If the current Search provides garbage, you can still try the old one listed in my signature. Search for create access point for example.

The code I'm using is based off this http://wiki.forum.nokia.com/index.php/Image:WLanEx.zip
and a couple of other examples in the wiki, but I seem to be unable to get it to work correctly.

add another
commDb = CCommsDatabase::NewL();
at the end of the code can solve this problem.
