Detailed Description

Number Of Completed Packets.

The description below is extracted from Core_v6.3, Vol 4, Part E, Section 7.7.19

This event is used by the Controller to indicate to the Host how many HCI Data packets or HCI ISO Data packets have been completed for each Handle since the previous HCI_Number_Of_Completed_Packets event was sent to the Host. This means that the corresponding buffer space has been freed in the Controller and is available for new packets to be sent. Based on this information and the return parameters of the HCI_Read_Buffer_Size and HCI_LE_Read_Buffer_Size commands, the Host can determine for which Handles the following HCI packets should be sent to the Controller. The HCI_Number_Of_Completed_Packets event shall not specify a given Handle before the Controller has sent the event indicating that the corresponding connection or BIG has been created or after it has sent the event indicating disconnection of the corresponding connection or indicating that the BIG has been terminated. While the Controller has HCI Data packets or HCI ISO Data packets in its buffer, it shall keep sending the HCI_Number_Of_Completed_Packets event to the Host at least periodically, until it finally reports that all the pending packets have been completed. The rate with which this event is sent is manufacturer specific.

Note: HCI_Number_Of_Completed_Packets events will not report on synchronous Connection_Handles if synchronous Flow Control is disabled. (See Section 7.3.36 and Section 7.3.37.)
