The following Compilation Option of ola_adapter.h allows use of Agnos Kernels through External Entry-Points:

#define OLA_OPTION_EXTERNAL_ENTRY_POINT

OLA API functions to be used with External Entry-Points are:

• During Terminal Initialization

  • ola_initialize_at_start_up()

  • ola_pubkey_flush()

  • ola_pubkey_add()

• For each Payment Transaction

  • ola_contactless_flush_aid_supported()

  • ola_emv_set_tag()

  • ola_contactless_add_aid_supported()

  • ola_contactless_do_transaction()

  • ola_contactless_get_outcome()

  • ola_emv_get_data()

  • ola_contactless_get_UI_request_upon_outcome() (when available)

  • ola_contactless_get_UI_request_restart() (when available)

  • ola_contactless_clean()

The following OLA API functions are irrelevant for use (i.e., shouldn’t be used) with External Entry-Points:

• ola_contactless_preprocess()

• ola_contactless_build_candidate_list()

• ola_contactless_final_select_candidate()

Sample Flow

The following diagram shoes sample use of the OLA for Agnos API with External Entry-Points:

NOTE: Optionally if [Outcome Parameters] returned from ola_contactless_get_outcome() indicate presence of a UI Request Message on Outcome and/or UI Request message on Restart, the function/methods ola_contactless_get_UI_request_upon_outcome() and ola_contactless_get_UI_request_restart() can be used for retrieving corresponding UI Request informations
