Qml bluetooth chat server

mehrdad

Hi,

there is an example of qml bluetooth chat client
http://doc-snapshot.qt-project.org/qt5-5.4/qtbluetooth-chat-example.html

but i do not know how can i create its server side and actually i dont know how bluetooth service works

how can i connect BluetoothSocket to BluetoothService

i guess i should create a socket for any client and connect this sockets to a service and this service gives message of clients and send it to all clients...is it true? and if the answer is positive how can i do that?

thanks...

Hi,

In the Qt installation on your computer, you have the full source code of all the example projects. I suggest you check the projects in the bluetooth folder.

thanks, but i know that... this examples based on c++ and qml together...
i need an example of qml version and just its server side...
i try to find out something from qt examples but unfortunately this examples is so intricate... .

For a Bluetooth server, you can't avoid C++.

Are you sure?so what is BluetoothService and what mean this?

http://doc.qt.io/qt-5/qtbluetooth-qmlmodule.html

The Qt Bluetooth QML Types enable an application to scan for devices and connect and interact with them in an easier way than the C++ Classes. However, it is a bit more limited than the C++ API. You can always use the C++ API to create QML plugins with the flexibility you need.

From BluetoothService documentation: "It allows a QML project to get information about a remote service, or describe a service for a BluetoothSocket to connect to."

To implement a service, you need a server. From the QBluetoothServer doc.: "The QBluetoothServer class uses the RFCOMM or L2cap protocol to communicate with a Bluetooth device. QBluetoothServer is used to implement Bluetooth services over RFCOMM or L2cap."
