Store Client Configuration Characteristic value right after it has been updated.

By default, CCC is only stored on disconnection. Choosing this option is safer for battery-powered devices or devices that expect to be reset suddenly. However, it requires additional workqueue stack space.

Direct dependencies¶

BT_SETTINGS && BT_HCI_HOST && BT_HCI && BT

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
