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.
