I'm trying to get bluetooth to do Simple Secure Pairing. Trying....

WalterWhite

When I run this code on my embedded system, it give me a dialog on android
Enter 0000 or 1234
Both of course don't work.

Any clues to what I might be doing wrong?
(Been trying different things for about 4 days. :( )

My StartServer function:
m_pBluetoothDevice = new QBluetoothLocalDevice();

    m_pBluetoothDevice->setHostMode(QBluetoothLocalDevice::HostConnectable);


    QObject::connect(m_pBluetoothDevice, &QBluetoothLocalDevice::deviceConnected, this, &CTAKLrfGpsBluetoothServer::deviceConnected, Qt::QueuedConnection);
    QObject::connect(m_pBluetoothDevice, SIGNAL(pairingDisplayPinCode(QBluetoothAddress,QString)), this, SLOT(pairingDisplayPinCode(QBluetoothAddress,QString)));
    QObject::connect(m_pBluetoothDevice, SIGNAL(pairingDisplayConfirmation(QBluetoothAddress,QString)), this, SLOT(pairingDisplayConfirmation(QBluetoothAddress,QString)));
    QObject::connect(m_pBluetoothDevice, SIGNAL(pairingFinished(QBluetoothAddress,QBluetoothLocalDevice::Pairing)), this, SLOT(pairingFinished(QBluetoothAddress,QBluetoothLocalDevice::Pairing)));
    QObject::connect(m_pBluetoothDevice, SIGNAL(error(QBluetoothLocalDevice::Error)), this, SLOT(pairingError(QBluetoothLocalDevice::Error)));


    const QBluetoothAddress &localAdapter = QBluetoothAddress();

    m_pRfcommServer = new QBluetoothServer(QBluetoothServiceInfo::RfcommProtocol, this);
    QObject::connect(m_pRfcommServer, &QBluetoothServer::newConnection, this, &CTAKLrfGpsBluetoothServer::newConnection, Qt::QueuedConnection);

    m_pRfcommServer->setSecurityFlags(QBluetooth::Authentication);

    bool result = m_pRfcommServer->listen(localAdapter);
    if (!result) {
        qWarning() << "**************** ERROR ERROR ERROR  **************************";
        qWarning() << "             Cannot bind TAK server to" << localAdapter.toString();
        qWarning() << "**************** ERROR ERROR ERROR  **************************";
        return;
    }


    //! [Class Uuuid must contain at least 1 entry]
    QBluetoothServiceInfo::Sequence classId;

    classId << QVariant::fromValue(QBluetoothUuid(QBluetoothUuid::SerialPort));
    serviceInfo.setAttribute(QBluetoothServiceInfo::BluetoothProfileDescriptorList,
                             classId);

    classId.prepend(QVariant::fromValue(QBluetoothUuid(serviceUuid)));

    serviceInfo.setAttribute(QBluetoothServiceInfo::ServiceClassIds, classId);
    serviceInfo.setAttribute(QBluetoothServiceInfo::BluetoothProfileDescriptorList,classId);
    //! [Class Uuuid must contain at least 1 entry]

    //! [Service name, description and provider]

    //! [Service UUID set]
    serviceInfo.setServiceUuid(QBluetoothUuid(serviceUuid));
    //! [Service UUID set]

    //! [Service Discoverability]
    QBluetoothServiceInfo::Sequence publicBrowse;
    publicBrowse << QVariant::fromValue(QBluetoothUuid(QBluetoothUuid::PublicBrowseGroup));
    serviceInfo.setAttribute(QBluetoothServiceInfo::BrowseGroupList,
                             publicBrowse);
    //! [Service Discoverability]

    //! [Protocol descriptor list]
    QBluetoothServiceInfo::Sequence protocolDescriptorList;
    QBluetoothServiceInfo::Sequence protocol;
    protocol << QVariant::fromValue(QBluetoothUuid(QBluetoothUuid::L2cap));
    protocolDescriptorList.append(QVariant::fromValue(protocol));
    protocol.clear();
    protocol << QVariant::fromValue(QBluetoothUuid(QBluetoothUuid::Rfcomm))
             << QVariant::fromValue(quint8(m_pRfcommServer->serverPort()));
    protocolDescriptorList.append(QVariant::fromValue(protocol));
    serviceInfo.setAttribute(QBluetoothServiceInfo::ProtocolDescriptorList,
                             protocolDescriptorList);
    //! [Protocol descriptor list]

    //! [Register service]
    serviceInfo.registerService(localAdapter);
    //! [Register service]


    m_pBluetoothDevice->setHostMode(QBluetoothLocalDevice::HostDiscoverable);

Hi,

What version of Qt are you using ?
On what platform(s) ?

WalterWhite

Using QT 5.6.2

WalterWhite

Oh, and under ubuntu. (on embedded platform)

SGaist

Qt 5.6.2 is a bit outdated, any chance of testing against a more recent version of Qt ? 5.12 is the current and LTS release.

WalterWhite

5.10.1 does same thing.

WalterWhite

Even though I specify secure in security call, I see a pin dialog pop up on android saying enter 0000 or 1234 (both don't work)

WalterWhite

I found the solution.
I needed to turn on SSP by using a call to the system
system("hciconfig hci0 sspmode 1");
