void CListener::StartListenerL(TInt& aChannel)
{

if ( iState!=ENone )
{
User::Leave(KErrInUse);
}
iState=EConnecting;

TProtocolDesc pdesc;
User::LeaveIfError(iSocketServ.FindProtocol(KRfComm(), pdesc));

User::LeaveIfError(
iListenSock.Open(iSocketServ,
pdesc.iAddrFamily,pdesc.iSockType,KRFCOMM)
);

User::LeaveIfError(iListenSock.GetOpt(KRFCOMMGetAvailableServerChannel,
KSolBtRFCOMM, aChannel));

TBTSockAddr btsockaddr;
btsockaddr.SetPort(aChannel);

User::LeaveIfError(iListenSock.Bind(btsockaddr));

iListenSock.Listen(KSizeOfListenQueue);

TBTServiceSecurity secSettings;

TUid settingsUID;
settingsUID.iUid = KBT_serviceID;
secSettings.SetUid(settingsUID);

secSettings.SetAuthentication(EFalse);
secSettings.SetAuthorisation(EFalse);
secSettings.SetEncryption(EFalse);

btsockaddr.SetSecurity(secSettings);

iSock.Close();

User::LeaveIfError(iSock.Open(iSocketServ));

iListenSock.Accept(iSock,iStatus);
SetActive();
