CONFIG_BT_SETTINGS_CCC_STORE_ON_WRITE

Store CCC value immediately after it has been written

Type: bool

Help

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_CONN && BT_SETTINGS && BT_HCI_HOST && BT_HCI && BT

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
