Question about file exchange between applications

[Nils]

Hello,
I'm not sure if this is the right place for my topic but I will ask nevertheless.
I'm developing an Android/ iOS App which show and log data from the Sensors. Additionally I will have a desktop program, not done yet, to manage the data files.
The data from the smartphone app has to be transferred to the desktop application, with the use of a web server.
The data can be saved as a txt, xml or csv file. In most of the time it will be xml.

So here is my question.
I'm not that familiar with the networking stuff. So I missing the starting point. I try one of the example which uses qml web sockets but it dosen't work right.
So if someone can give me a hint how to do the file transfer I would be very thankful.

For my developing I use QML with V-Play and C++.

@Nils You can start here: http://doc.qt.io/qt-5/qtnetwork-programming.html
And take a look at Qt examples.

So I read the page and try to use the QUdpSocket example.
I implementiert the sender in my Android application and the receiver in a second application on my computer. In the wireless network of our lab the communication works and I can receive the datagrams from my android app.
Now is the questions what I have to do next to send my xml files over the sockets?

At the moment I would try to search for network partners Wirth a Udo Broadcast to establish a direct connection with Tcp and send my data through the Tcp Socket.
Is this right or do I miss something?

Hi,

That's one way to do. Another one would be to use Zeroconf to discover the service you want to connect to. It might make things easier.

Hope it helps
