Help¶

When selected, the Bluetooth stack will take care of storing
(and restoring) the Bluetooth state (e.g. pairing keys) and
configuration persistently in flash.

When this option has been enabled, it's important that the
application makes a call to settings_load() after having done
all necessary initialization (e.g. calling bt_enable). The
reason settings_load() is handled externally to the stack, is
that there may be other subsystems using the settings API, in
which case it's more efficient to load all settings in one go,
instead of each subsystem doing it independently.
