CONFIG_BT_CTLR_FAST_ENC

Fast Encryption Setup

Type: bool

Help

Enable connection encryption setup in 4 connection events.
Peripheral will respond to Encryption Request with Encryption Response
in the next connection event, and will transmit Start Encryption
Request PDU in the same connection event, hence completing encryption
setup in 4 connection events. Encrypted data would be transmitted as
fast as in 4th connection event from Encryption Request.

Direct dependencies

BT_CTLR_LE_ENC && BT_CONN && BT_LL_SW_SPLIT && BT_CTLR && BT_HCI && BT

(Includes any dependencies from ifs and menus.)

Default

y if BT_HCI_RAW
