Hi,
are you on Qt 4.7.1?

There, the network transport seems to be damaged…

Please ignore the person above me.

Symbian requires an extra line for network to work on device.
You may need to modify the PRO file with:

In which case you just need:

Thanks for your reply.

as you said,I add “CAPABILITY += NetworkServices WriteDeviceData ReadDeviceData” to the pro file.
then I also add Qt += network to make the qt app to access the internet.

what did you mean of “DEFINES += NETWORKACCESS” Should it add to the pro file ?

Yes,My sdk is Qt for Symbian4.7.1

why did you said the network was damaged?

Oh in QtCreator 2.1, it adds a PRI (rules) file that allows you to use that DEFINES line to get network working properly. No need to mess with anything else.

If you’re not using 2.1, just do what you’ve done.

Is it working now?

I have performed tests with network apps in my office, and under Symbian, Qt 4.7.1 breaks most network apps. Try Qt 4.6.3 or 4.7.0…

For further reference, see these two bugs I reported:
http://bugreports.qt.nokia.com/browse/QTBUG-15856
http://bugreports.qt.nokia.com/browse/QTBUG-15858

I see you’re adding those videos. They don’t really prove much in this case though.

For what it’s worth, all Qt networking apps work perfect on Symbian 4.7.1 here.
It is likely a configuration error. Config may have changed between 4.7.0 and 4.7.1, I’m not sure. I use create new project on new Qt bases to avoid such issues.

Hi Sacha,
what they prove is: app used to work before, now it doesn’t anymore.

So does QFtp example work on your XM5800 without the bearer issue?

sorry to reply for you so late.
I’m a newbie for Qt for Symbian.

You meaned that I would add a .pri file to my project?
and the content of .pri file is
@ Needs to be defined for Symbian DEFINES += NETWORKACCESS
@#?

How does the app work with the .pri file? should it include by the .cpp file or the .h file?

Hello hisong,
first of all, big apologies for hijacking your thread. We moved onto talking about what I believe to be a bug in Qt.

Prior to Qt 4.7, you didn’t need to add any Defines into the .pro file. You just needed to add the capability like this:

How it looks on Qt 4.7.1, we are currently investigating!

I also met the second “Bug” you post when I was developing an app using network of Qt.

I met the [Qt Message] exception on 3 [will close the socket handle – hack] when I debug the app.

I don’t know why the new version turn up so many bug? The new version SDK should work more stable than the last version,isn’t is?

I will try the method you suppose.I will link to you if there are other questions.

Thanks very much.

Hello hisong,
thank you so much for talking back!

Unfortunately, these regressions do happen. In fact, it probably also is my fault at least to some extent – I didn’t test Qt 4.7.1 immediately after release as I usually do, and thereby could not inform via my web site.

Either way, let’s stay in touch. Nokia IS interested in fixing these bugs!!!

It’s interesting because obviously it doesn’t happen to everyone (whoever released Qt4.7.1 for Symbian and me, for starters).

I wonder what you (tamhanna) and hisong1988 have in common here.
I really don’t think my phone’s firmware has changed this.

About the PRI files: they are included in your PRO file. If you make new project in QtCreator2.1, this will be set out for you. Otherwise, don’t worry about it.
Maybe you should try QtCreator 2.1.

Hi xsacha,
you are on a different hardware platform.

At least for me, it works in the simulator still. The error occurs in totally different ways on N97mini and XM5800. So this seems to be hardware dependent.

Hello,tamhanna

Yes,the capability “ReaUserData WriteUserData NetworkServices” I add to the pro file. It didn’t work.

Mostly,I really want to know how does this problem “A data abort exception has occurred
“ happened?
