typedef void(*

sl_mqtt_client_event_handler_t)(void *client, sl_mqtt_client_event_t event, void *event_data, void *context)

Handler for MQTT client Events.

typedef void(*

sl_mqtt_client_message_received_t)(void *client, sl_mqtt_client_message_t *message_to_be_published, void *context)

Handler for MQTT client RX message.

sl_mqtt_client_event_handler_t )(void *client, sl_mqtt_client_event_t event, void *event_data, void *context)

Handler for MQTT client Events.

Parameters

N/A	client	Client on which the event occurred.
N/A	event	Event occurred of type sl_mqtt_client_event_t
N/A	event_data	Event data for the data. This parameter would be non-null only for MQTT_CLIENT_MESSAGED_RECEIVED and MQTT_CLIENT_ERROR.
N/A	context	Context provided by user at the time of API call(sl_mqtt_client_init). The caller(sl_mqtt_client_init) must ensure that the lifecycle of the context is retained until the callback is invoked. The deallocation of context is also the responsibility of the caller.

sl_mqtt_client_message_received_t )(void *client, sl_mqtt_client_message_t *message_to_be_published, void *context)

Handler for MQTT client RX message.

Parameters

N/A	client	Client which has received message.
N/A	message_to_be_published	Message received of type sl_mqtt_client_message_t
N/A	context	Context provided by user at the time of Subscribe API call. The caller(the function or module that invokes the Subscribe API) must ensure that the lifecycle of the context is retained until the callback is invoked. The deallocation of context is also the responsibility of the caller.

Note

Due to the constraints from the firmware, is_retained, qos_level, packet_identifier, duplicate_message of sl_mqtt_client_message_t are not populated and shall be ignored while processing the message.
