- 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_TESTING && BT_SMP && BT_CONN && BT_HCI_HOST && BT_HCI && BT
(Includes any dependencies from ifs and menus.)
Defaults¶
No defaults. Implicitly defaults to n.
