| ** If the app is expecting a response to the event then it can |
| ** provide response buffer for collecting the response. If it |
| ** provides a response buffer it can also provide response |
| ** timeout indicating maximum timeout for the response. |
| ** Maximum of NFA_MAX_HCI_EVENT_LEN bytes APDU can be received |
| ** using internal buffer if no response buffer is provided by |
| ** the application. The app will be notified by |
| ** NFA_HCI_EVENT_RCVD_EVT after receiving the response event |
| ** or on timeout if app provided response buffer and response |
| ** timeout. If response buffer and response timeout is provided |
| ** by the application, it should wait for this event before |
| ** releasing the response buffer. If the application did not |
| ** provide response timeout then it should not release the |
| ** response buffer until it receives NFA_HCI_EVENT_RCVD_EVT or |
| ** after timeout it sends next event on the same pipe |
| ** and receives NFA_HCI_EVENT_SENT_EVT for that event. |
