-Background scanning will start every 5 minutes unless
-the scan list is empty. In that case, a simple backoff
-mechanism starting from 10s up to 5 minutes will run.
+If wifi is disconnected, the background scanning will follow a simple
+backoff mechanism from 3s up to 5 minutes. Then, it will stay in 5
+minutes unless user specifically asks for scanning through a D-Bus
+call. If so, the mechanism will start again from 3s. This feature
+activates also the background scanning while being connected, which
+is required for roaming on wifi.
+When BackgroundScanning is false, ConnMan will not perform any scan
+regardless of wifi is connected or not, unless it is requested by
+the user through a D-Bus call.
