Starting with BlueZ 5.23 and Linux 3.17, the Page Scan state is controlled by the kernel. If you have no devices paired / configured, then it will just disable Page Scan. If you do not know about devices, then there is also no point in allowing anybody to connect. You can use the management command Add Device to add BR/EDR devices. If you add at least one device, then Page Scan will be enabled automatically by the kernel. If you want to be always connectable, then you can set the device manually connectable. Using bluetoothctl does exactly the right thing. For being discoverable, you need to be connectable and discoverable. So Page Scan and Inquiry Scan enabled. However if you do not have any paired devices and turn discoverable back off, then both will be disabled. Just try it. Pair with a device and see that Page Scan gets turn on magically.
