I have try whith the Read() and Receive() functions from RSocket but it was nothing.

Thanks for Your help.



void CBT1AppUi::Init()
{
RSocketServ iSocketServer;
RSocket iSendingSocket;
iSocketServer.Connect();
TProtocolDesc pInfo;
TBool BTFound;
TInt KRfcommChannel;

KRfcommChannel = 1;


User::LeaveIfError(iSocketServer.FindProtocol(_L("BTLinkManager"),pInfo));

RHostResolver hr;
User::LeaveIfError(hr.Open(iSocketServer,pInfo.iAddrFamily,pInfo.iProtocol));


TInquirySockAddr addr;
TNameEntry entry;
addr.SetIAC(KGIAC);
addr.SetAction(KHostResInquiry|KHostResName);
TRequestStatus status;
hr.GetByAddress(addr, entry, status);
User::WaitForRequest(status);

if (status == KErrNone)
{
BTFound = EFalse;
if ( entry().iName.Match( _L("BlueSerial-Laptop") ) != KErrNotFound) //Senden an BT device mit namen MyHandy
{

hr.Close();
User::LeaveIfError(iSendingSocket. Open(iSocketServer,KBTAddrFamily,KSockStream,KRFCOMM));

iBTSockAddr.SetBTAddr(iBTSockAddr.BTAddr());

iBTSockAddr.SetPort(KRfcommChannel);

TRequestStatus istatus;
iSendingSocket.Connect(iBTSockAddr,istatus);

User::WaitForRequest(istatus);
