| help |
| The number of transmitted air interface ACL packets to trigger the |
| Number Of Completed Packets HCI event. In most cases, this should be |

| help |
| The maximum data length that the application expects to send in a |
| Periodic Advertising with Response packet. The controller will use |
| this hint to optimize the scheduling of concurrent connections. |

| help |
| The number of packets the controller requests from the host in one LE |
| Periodic Advertising Subevent Data Request event. This is a tradeoff |
| between the controller's memory usage and the number of separate HCI |
| events the controller must send. This value is applied to each PAwR |
| advertiser separately. Note that the request count is limited by the |
| number of subevents in the PAwR train, and the request advance |
| configuration. |
| |
| config BT_SILABS_EFR32_PAWR_PACKET_REQUEST_ADVANCE |
| int "Number of subevents in advance to request PAwR data" |
| default 1 |
| range 1 6 |
| help |
| The controller asks the host to provide data for upcoming subevents |
| before the subevents are sent over the air. This parameter is used to |
| configure how many subevents in advance the requests are sent to the |
| host. The bigger the advance is, the more time the host has to |
| process the request, but the controller has to reserve more memory |
| for buffering the subevent data. Note that the maximum advance is |
| limited by the number of subevents configured for a PAwR train. |
| Therefore, the actual advance may be less than the number configured |
| in this parameter. |
