access point on real device problem

[morost]

Hi, I'm trying to create a new access point (wlan) on my e60 device

I use the code finded at the link :
http://forum.nokia.com/document/Foru...ting_to_it.htm
in the forum nokia tachnical library

or
http://forum.nokia.com/document/Foru...g_WLAN_APs.htm


In emulator works well ( but I use gprs , not wlan... because wlan is not supported in emulator ) but in real device the code stops at the line :

TUint32 newApId = handler->CreateFromDataL(*wlan);

that is the line when access point is writed in comm database...

I've read the documentation and I have find that CreateFromDataL ( class CApDataHandler ) stops for :

- Insufficient memory
- Server connection failure.
- Lock already present by other task.
- Attempting to create new in protected tables will result in KErrAccessDenied

Anyone know the problem ?
Maybe I need special capabilities for write in this table or the tables are protected ?

My e60 is a standard device, not an operator version....

thanks.

Hi,

i have same problem!!!
Have you any solution about this now?
I try to create a WLAN access point on s60 device!!

Thanks!!

so when it stops in the line, does it crash the program with error , or just jams ?
you could aos try TRAPping the error code, and if it is for example -46, it would indicate that you are missing required capabilities for executing the function.

I use this code :

CApAccessPointItem *newAP = CApAccessPointItem::NewLC();

newAP->SetNamesL(_L("NewAP);

 newAP->SetBearerTypeL(EApBearerTypeGPRS);

//then you can set ap parameters like:
 newAP->WriteBool(EApGprsIfPromptForAuth,EFalse);
// ecc.

// Store it into the CommsDb

CCommsDatabase *commDb1 = CCommsDatabase::NewL();
CleanupStack::PushL(commDb1);
CApDataHandler *handler = CApDataHandler::NewLC(*commDb1);	
TUint32 newApId = handler->CreateFromDataL(*newAP);
							
CleanupStack::PopAndDestroy(3);

In my test code I use only WriteDeviceData capability.

Hi ,

at first thanks four your posts!

In emulator i have a System error(-1) on the line

apid = handler->CreateFromDataL(*wlanAp);

wlanAP is object of CApAccessPointItem! and data base is open also!!!

firstly you shuld always check the SDK docs for required capabilities, having just WriteDeviceData is not enough.

so try first adding all, then -1 just tells that something is not found, so check the settings data you are trying to set again.

Hi yucca,

i just started to develop with this SDK!
I use S60_3rd_FP1 v9.2!!!
How can i found out which capabilities are required?
I have certificate from SymbianSigned!

Thanks,

Sorry... my last post wasn't complete...

I'm able to create access points, the code that I posted works well, and only WriteDeviceData is needed ( I re-tested the code 5 minutes ago.. only this capability is needed ).
I know that S60 doc indicate ReadUserData,WriteUserData, ReadDeviceData, WriteDeviceData capabilities ( for CApAccessPointItem, CApDataHandler... ) but for this operation, that is only a write, only WriteDeviceData is needed.
If you want to use CApAccessPointItem for others operations ( read, ecc. ) probably all the 4 capabilities are needed.

I re-write the code.. the last that I posted creates a Gprs AP...

CApAccessPointItem *wlan = CApAccessPointItem::NewLC();
wlan->SetNamesL(_L("NewWiFiAP"));
wlan->SetBearerTypeL(EApBearerTypeWLAN);
wlan->WriteTextL(EApWlanNetworkName, _L("WlanAP"));
// Store it into the CommsDb
CCommsDatabase *commDb = CCommsDatabase::NewL();
CleanupStack::PushL(commDb);
CApDataHandler *handler = CApDataHandler::NewLC(*commDb);
TUint32 newApId = handler->CreateFromDataL(*wlan);
CleanupStack::PopAndDestroy(3); // handler, commDb, wlan

Ste

p.s. for dejjan .. in 3rd edition api reference ( sdk folder "S60doc" ) you can find required capabilities
