Public bug reported:
Steps to reproduce:
* Open the settings app
* enter the Bluetooth settings page
* close the settings app (do not exit the Bluetooth page)
=> device can still be found by other hosts and hciconfig confirms that
ISCAN is still enabled.
As Bluetooth ISCAN mode consumes a significant amount of battery, ISCAN
mode should be disabled when the app is closed or inactive.
>From the bluez docs:
boolean Discoverable [readwrite]
Switch an adapter to discoverable or non-discoverable
to either make it visible or hide it. This is a global
setting and should only be used by the settings
application.
If the DiscoverableTimeout is set to a non-zero
value then the system will set this value back to
false after the timer expired.
So it would seem to me the best approach would be to pass a non-zero
value for DiscoverableTimeout, something like 30 secs, so that the stack
disables ISCAN mode on it's own if the ui isn't actively calling this
again every 30 secs.
