SetMajorClassOfDevice() not working...

[amitsingh18]

Hi all,

i am a problem with Bluetooth device searching...my code is below, can anyone tell me that why SetMajorClassOfDevice(EMajorDeviceLanAccessPoint); is not working...my code is:

// Code Here
TInt error=KErrNone;
TPtrC deviceName;
RSocketServ socketServ;
TInt ret_val;
ret_val=socketServ.Connect();

TProtocolDesc pInfo;
_LIT(KL2Cap, "BTLinkManager");

TBuf<32> tbuf_L2cap;
tbuf_L2cap=KL2Cap;
ret_val=socketServ.FindProtocol(tbuf_L2cap,pInfo);

RHostResolver hr;
ret_val=hr.Open(socketServ,pInfo.iAddrFamily,pInfo.iProtocol);

TInquirySockAddr addr;
TNameEntry entry;
addr.SetIAC(KGIAC);

TRequestStatus status;
addr.SetMajorClassOfDevice(EMajorDeviceLanAccessPoint);
/* addr.SetMinorClassOfDevice(EMinorDeviceLANFullyAvailable|EMinorDeviceLANServiceOne|EMinorDeviceLANServiceTwo
|EMinorDeviceLANServiceThree|EMinorDeviceLANServiceFour|EMinorDeviceLANServiceFive|
EMinorDeviceLANServiceSix|EMinorDeviceLANNoService);
addr.SetAction(KHostResInquiry|KHostResName|KHostResIgnoreCache);
*/
hr.GetByAddress(addr, entry,status);
User::WaitForRequest(status);

if (status == KErrNone)
{
do
{
deviceName.Set(entry().iName);

TBuf<20> Dnane=deviceName;
//CEikonEnv::Static()->AlertWin(Dnane);

error = hr.Next( entry );
}while( error != KErrHostResNoMoreResults );
}

// End Code

My problem:

1.In this when i am calling addr.SetIAC(KGIAC); function i am getting all the devices and when i am putting KLIAC instead of KGIAC then i am not getting any one devices...why...???

2.Why SetMajorClassOfDevice() is not working, when i am paasing the approapriate Major device Class to this function...???

can anyone help me...

Thanks Alot

Are any of the devices you are enquiring on set into Limited Inquiry mode? If not, then the KLIAC will return nothing. As I understand it, this mode is cheifly used if you have access to both client and server, for example for point to point between two phones.
