How to use bearer management to select access point

[ruiran]

QNetworkConfigurationManager manager;
QNetworkConfiguration cfg = manager.defaultConfiguration();
m_session = new QNetworkSession(cfg, this);
m_session->open();

With these codes，my app asked me to select AP for ONLY 3 times and after that the selected AP was likely set as the default one，so what's wrong with this case happened？

I used this piece of codes and got the same result.

Any help is welcome and appreciated.

Thanks!

I don't quite understand the question. Are you saying that defaultConfiguration) returns a valid configuration but the platform still asks you what to use? Or are you asking why the application asks you more than once?

What type of configuration do you get? If it is UserChoice it means that no default has been set. Therefore by testing for its type you can determine whether the subsequent QnetworkSession:pen() call is going to popup a platform dialog asking the user what to use.

Also S60 3.1 devices do not have default configuration. The always return a configuration of type UserChoice.

I think he wants to know how to set a configuration other than "ask".

I wanna know why the application asks me more than once to select AP and I used N95 to test my app.
Actually, I only want to select AP only once when application launched and then the selected AP would be saved as default， but now I can't get this completed. I just want to know how to set my selected AP as default. I have already used AccessPointManager in mobile-extension to accomplish this case and I can get my expected result！

Yes, I wanna to know how to set my selected AP as default one so that application would no longer ask me to select AP more than once.

On the emulator I can get the expected result（popup a dialog asking the user to select AP only once）while on N95 it will popup three times！

Have you tried setting a selected AP (and not "default")?

Thanks, but how can I do it?

Not saying this is right, but it seems to work for some simple cases:

	// Note:  Should be calling updateConfigurations here.  See QNetworkConfigurationManager::allConfigurations writeup.

	QNetworkConfiguration cfg = manager.defaultConfiguration();
	if (!cfg.isValid() || (!canStartIAP && cfg.state() != QNetworkConfiguration::Active)) {
		QMessageBox::information(this, tr("TestMobility"), tr("Available Access Points not found."));
		return;
	}
	
	if (cfg.type() == QNetworkConfiguration::UserChoice) {
		QNetworkConfiguration::StateFlags flags = QNetworkConfiguration::Discovered | QNetworkConfiguration::Active;
		QList<QNetworkConfiguration> allCfg = manager.allConfigurations(flags);
		// Just take the first one -- need a better algorithm to pick one
		if (allCfg.count() > 0) {
			cfg = allCfg.at(0);
		}
	}

			cfg = allCfg.at(0);
		}
	}

I tried this method with a simple case, but got the same result.

Do you know if allCfg.count() is greater than zero?
