Bluetooth pairing problem

[naimidrees]

Dear All,

I want to pairing a Bluetooth device by using following code. But I failed the pairing device. Anybody can help me, I have took this piece of code from QBluetooth project.

<code>

TBool QBtLocalDevicePrivate::AddNewDevice(const QBtDevice& device)
{
try
{
CBTDevice* newDev;

RBTRegServ regServ;

RBTRegistry view;

TRequestStatus stat;

QT_TRAP_THROWING
(
newDev = CBTDevice::NewL(device.getAddress().convertToSymbianBtDevAddr()));

newDev->SetDeviceClass(TBTDeviceClass(device.getType()));

TBuf8<4> psd(_L8("0000"));

TPINCodeV10 pinCode10;

pinCode10.iLength = 4;

memcpy(pinCode10.iPIN,psd.Ptr(),4);

TBTPinCode pinCode(pinCode10);

TPtrC8 name8((const TUint8 *)device.getName().toUtf8().data(),device.getName().toUtf8().size());

TPtrC16 name16(device.getName().utf16());

QT_TRAP_THROWING(
{
newDev->SetDeviceNameL(name8);

newDev->SetFriendlyNameL(name16);

newDev->SetPaired(ETrue);

newDev->SetPassKey(pinCode);

regServ.Connect();

view.Open(regServ);

view.AddDeviceL(*newDev,stat);
});

User::WaitForRequest(stat);

stat.Int();

view.Close();

regServ.Close();

SafeDelete(newDev);
}
catch(char* str)
{
return false;
}

return true;
}

what are devices you using ?

Tell your problem in detail ?

Hi,
For both RFCOMM and L2CAP we need to set the security flags. When you start your server that need to set by this method call.

QRfcommServer::setSecurityFlags(QBluetooth::SecurityFlags security) // check for L2CAP side also
See some doc from http://doc.qt.nokia.com/qtmobility-1...#Security-enum
There could be some example in Qt mobility Bluetooth example (I am not sure though, check it yourself)

I am using a Bluetooth device with serial communication client. Ihave communicated with the device successfully. But I do the pair device manually. But I will have to pairing the Bluetooth device by the code. I have tried the code given blow is not not working. Kindly help me.

Hi,
Could you post related part of your code here?

@mahbub_s60,

the pairing is an operation completely different and unrelated with the RFCOMM and L2CAP operations.
Are you sure we need to take kare of the security flags in order to achieve the pairing?

@naimidrees Thank you for your post, i have never seen those functions regarding the pairing, that is why the pairing functions are missing from the library that you used. If you keep having troubles with it, try the Qt Mobility 1.2 where is the official Bluetooth API.

[mahbub_s60]

favoritas37, you are absolutely right. Original post was about pairing device nothing to do with L2CAP or RFCOMM and I jumped to service level, sorry I mislead !

Ok with Symbian this is not supported. Qt Mobility on Symbian does not support it either for 3rd party. I shall try to check (in future and publish it as wiki articles if possible) if we could do something for 3rd party developers.
