dbus-send --system --type=method_call --print-reply --dest=org.bluez /org/bluez/hci0 
org.bluez.Adapter.SetMode string:discoverable

More or less.

add
discovto 0;

to the 'device' section of hcid.conf to make it permanent, or a non-zero value 
to set a time before the device becomes hidden again (i think in minutes, but 
not sure)
