Q: 

Detect roaming (switching the Access Point) with QtMobility?

Hello!

I need to write an application, that detects roaming from one access point to another if I'm connected to WLAN. Unfortunately I couldn't find anything that detects roaming for me. All I could find are some explanations in the Bearer API. One sentence says:

The second form of roaming is referred to as Forced Roaming. The system simply changes the link layer without consulting the application. It is up to the application to detect that some of its internal socket may have become invalid.

Since I'm not a network guy I don't have any idea how I could track roaming. It would be enough to know, that the device switched from one access point to another.

Maybe anybody of you can help me out on that?

Thanks a lot!

I believe this is exactly the thing you need: http://doc.qt.nokia.com/qtmobility-1.0/qnetworksession.html#newConfigurationActivated

Thx. Must have overseen that (I've already tried it with stateChanged, but that didn't work for me).I will try it out and give feedback.

It seems, that this only works when my device switches the network. What I want to achieve is to get notified when my device switches Access Points INSIDE one network.Let's say you have a home network with 3 access points (one in each floor). you are in the first floor connected to your network on access point 1. now you go upstairs and access point 2 offers a better signal strength than access point 1. now your device will switch to access point 2. and this is the event I want to catch.

Check out RConnectionMonitor and MConnectionMonitorObserver classes. THey allow your code to get notified when connections change
