CONFIG_BT_SMP_USB_HCI_CTLR_WORKAROUND
¶
Workaround for USB HCI controller out-of-order events
Type: bool
Help¶
This option enables support for USB HCI controllers that sometimes send out-of-order HCI events and ACL Data due to using different USB endpoints. Enabling this option will make the master role not require the encryption-change event to be received before accepting key-distribution data. It opens up for a potential vulnerability as the master cannot detect if the keys are distributed over an encrypted link.
Direct dependencies¶

&& BT_SMP
&& BT_CONN
&& BT_HCI_HOST

(Includes any dependencies from ifs and menus.)
