Callback Framework#

sl_wifi_callback_function_t#

typedef sl_status_t(* sl_wifi_callback_function_t) (sl_wifi_event_t event, void *data, uint32_t data_length, void *arg) )(sl_wifi_event_t event, void *data, uint32_t data_length, void *arg)

Generic Wi-Fi callback function type.

sl_wifi_scan_callback_t#

In case of event failure, SL_WIFI_FAIL_EVENT_STATUS_INDICATION bit is set in event, data will be of type sl_status_t and data_length can be ignored

sl_wifi_stats_callback_t#

typedef sl_status_t(* sl_wifi_stats_callback_t) (sl_wifi_event_t event, void *data, uint32_t data_length, void *arg) )(sl_wifi_event_t event, void *data, uint32_t data_length, void *arg)

Wi-Fi stats callback type.

In case of event failure, SL_WIFI_FAIL_EVENT_STATUS_INDICATION bit is set in event, data will be of type sl_status_t and data_length can be ignored Note

• : SL_WIFI_STATS_TEST_MODE_EVENT -> Coming soon

• : SL_WIFI_STATS_MODULE_STATE_EVENT -> sl_si91x_module_state_stats_response_t

sl_wifi_join_callback_t#

typedef sl_status_t(* sl_wifi_join_callback_t) (sl_wifi_event_t event, char *data, uint32_t data_length, void *arg) )(sl_wifi_event_t event, char *data, uint32_t data_length, void *arg)

Wi-Fi join callback type.

In case of event failure, SL_WIFI_FAIL_EVENT_STATUS_INDICATION bit is set in event, data will be of type sl_status_t and data_length can be ignored

sl_wifi_twt_config_callback_t#

typedef sl_status_t(* sl_wifi_twt_config_callback_t) (sl_wifi_event_t event, sl_si91x_twt_response_t *data, uint32_t data_length, void *arg) )(sl_wifi_event_t event, sl_si91x_twt_response_t *data, uint32_t data_length, void *arg)

TWT Response callback type.

In case of event failure, SL_WIFI_FAIL_EVENT_STATUS_INDICATION bit is set in event, data will be of type sl_status_t and data_length can be ignored

sl_wifi_set_callback#

sl_status_t sl_wifi_set_callback (sl_wifi_event_group_t group, sl_wifi_callback_function_t function, void * optional_arg)
