Description

This article explains how to get and set the time period for scanning WLAN networks using definitions from the CommsDat WLAN API (wlancdbcols.h).

Note: This API is not part of the public SDK. It can be found in the SDK API Plug-in.

Solution

 CCommsDatabase* iDb = CCommsDatabase::NewL();
 
 // Open user settings
 CCommsDbTableView* iDbtable = 
   iDb->OpenViewMatchingUintLC( TPtrC(WLAN_DEVICE_SETTINGS),
                                TPtrC(WLAN_DEVICE_SETTINGS_TYPE),
                                KWlanUserSettings );
 iDbtable->UpdateRecord();
 
 // Sets scan interval to 1 minute
 iDbtable->WriteUintL(TPtrC( WLAN_BG_SCAN_INTERVAL ), 60);
 User::LeaveIfError( iDbtable->PutRecordChanges() );
 // iScanNetworks gives the Scan interval which is set in seconds
 // (in this case it returns 60)
 TUint32 iScanNetworks;
 iDbtable->ReadUintL(TPtrC( WLAN_BG_SCAN_INTERVAL ), iScanNetworks);

As a special case, the WLAN scan can also be disabled. See Disabling WLAN scan using Symbian C++ for details how to do this programmatically.
