WLAN Scan through QNetworkConfigurationManager::updateConfiguration()

[theopulus]

I'm trying to get my app to show all the available WLANs calling updateConfiguration and catching the signal through updateCompleted, filling then a LIST with the results, but I only get the already stored APs and none of the available WLANs in the area.

What can be wrong?

I am facing the same problem. The call returns only the stored APs (both WLAN and others).

How do I do WLAN scanning using QT?

Take a look at the bearer manager:

A more complex example might be a Wireless LAN configuration which may comprise of hardware details such as the WLAN card address, wlan access point details and user specific information (for example username and password).

Once the network interface was configured and started according to the configuration blue print, multiple applications are free to use this link layer connection/session for their own socket operations.

Note that the QNetworkConfiguration object only provides limited information about the configuration details themselves. It's main purpose is to act as a configuration identifier through which link layer connections can be created, destroyed and monitored.

QNetworkSession class is used for the session.

Also you can see this below discussion which contains the test code for the WLAN, and discussed about bug.

@gnuton, I am using the example listed on this link (bearercloud). The problem is, the call to updateConfiguration only returns the existing APs (created previously on the phone). It does not scan for available (new) wifi APs in the vicinity.

I want to initiate a wifi scan, see the list returned and then connect to one of the new APs found. Is this possible with QT APIs?

You don't, it seems. On Symbian, you need to use WLAN Management API (CWlanMgmtClient, CWlanScanInfo from wlanmgmtclient.h) to initiate a WLAN scan. Currently Qt Mobility/Bearer Management implementation doesn't use it. There are also other methods to control the interval of automatic scans, but you'll need to resort to Symbian APIs in any case.

ok then... I'll wait for Qt mobility to be mature enough as it seems each time I want to use a mobile feature I find it's not 100% possible with Qt

Thanks for your answers...

You can use "Mobile Extensions" for WLAN scanning. I was able to use it and scan for WLAN APs on a Symbian phone. It does not give you full-fledged WLAN manager (e.g. you cannot add/configure APs), but simple scanning works good enough.
