Qt5.4.1, but "Bluetooth QML Ping Pong example" still does not work!

Alexorleon

Hello!

I'm trying to use the Qt 5.4.1 to create a connection between the two Android devices using bluetooth. ASUS_T00J android 4.4.2 and U30GT-H android 4.0.4. For example, I launched the "Bluetooth QML Ping Pong example", but it does not work.
http://doc.qt.io/qt-5/qtbluetooth-pingpong-example.html
After the message "Service found. Setting parameters..." nothing happens, no data exchange. And so indefinitely.

The feeling that is not processed:
signal connect(socket, SIGNAL(connected()), this, SLOT(serverConnected()));

System files are transferred, all right, mate there. Until then tried QTcpServer on these devices, everything works without problems.

I decided to bring data:
void Server::addService(const QBluetoothServiceInfo &service){

//setMessage("Service found. Setting parameters...");
qDebug() << "Service found. Setting parameters...";

//! [Connecting the socket]
socket = new QBluetoothSocket(QBluetoothServiceInfo::RfcommProtocol);
socket->connectToService(service);

qDebug() << service.serviceName();
qDebug() << service.device().address().toString();
qDebug() << service.serviceUuid();
qDebug() << service.isComplete();

qDebug() << socket->localAddress();
qDebug() << socket->localName();
qDebug() << socket->localPort();

qDebug() << socket->peerAddress();
qDebug() << socket->peerName();
qDebug() << socket->peerPort();

connect(socket, SIGNAL(connected()), this, SLOT(serverConnected()));
connect(socket, SIGNAL(readyRead()), this, SLOT(readSocket()));
connect(socket, SIGNAL(disconnected()), this, SLOT(serverDisconnected()));

//! [Connecting the socket]
m_serviceFound = true;

}

Outputs:
Service found. Setting parameters...

""
"XX:XX:XX:XX:XX:XX" - This is client. All is well.
"{e8e10f95-1a70-4b27-9ccf-02010264e9c9}"
true

"XX:XX:XX:XX:XX:XX" - This is server. All is well.
"U30GT-H"
0

"00:00:00:00:00:00"
""
0
Service scan done

Questions arise

Why serviceName() is empry?
What peerAddress() and why it empty? Returns the address of the peer device. This is client (ASUS_T00J)?

And why this is example not working? And "Bluetoth Chat Server example" too.
Somebody working examples with bluetooth?

I installed the Ubuntu 14.04, but does not turn on bluetooth.
I installed the OpenSUSE and I was able to run btchat. http://doc.qt.digia.com/qtmobility/btchat.html
Successfully connected to U30GT-H and produced messaging.

But between android devices nothing works.

And the example of "Bluetooth QML Ping Pong example" is also not works.

Sorry for my english.
