** The app will be notified by NFA_HCI_EVENT_SENT_EVT
** after successfully sending the event on the specified pipe
** or if an error occurs. The application should wait for this
** event before releasing event buffer passed as argument.
** 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.
**
** Returns NFA_STATUS_OK if successfully initiated
** NFA_STATUS_FAILED otherwise
