CONFIG_BT_HCI_ACL_FLOW_CONTROL¶
Controller to Host ACL flow control support
Type: bool
Help¶
Enable support for throttling ACL buffers from the controller to the host. This is particularly useful when the host and controller are on separate cores since it ensures that we do not run out of incoming ACL buffers.
Direct dependencies¶
(BT && BOARD_DISCO_L475_IOT1) || (BT_CONN && BT_HCI && BT)
(Includes any dependencies from if’s and menus.)
Defaults¶
- “n” if
BT&&BOARD_DISCO_L475_IOT1 - “y” if !
BT_CTLR&&BT_CONN&&BT_HCI&&BT - “y” if
BT_HCI_RAW&&BT_CONN&&BT_HCI&&BT
