CONFIG_BT_GATT_ENFORCE_CHANGE_UNAWARE

GATT Enforce change-unaware state

Type: bool

Help

When enable this option blocks notification and indications to client
to conform to the following statement from the Bluetooth 5.1
specification:
'...the server shall not send notifications and indications to such
a client until it becomes change-aware."
In case the service cannot deal with sudden errors (-EAGAIN) then it
shall not use this option.
