Detailed Description

Enumerated types of the MQTT library.

Enumeration Type Documentation

Values indicating if an MQTT connection exists.

Enumerator
MQTTNotConnected	MQTT Connection is inactive.
MQTTConnected	MQTT Connection is active.

The state of QoS 1 or QoS 2 MQTT publishes, used in the state engine.

Enumerator
MQTTStateNull	An empty state with no corresponding PUBLISH.
MQTTPublishSend	The library will send an outgoing PUBLISH packet.
MQTTPubAckSend	The library will send a PUBACK for a received PUBLISH.
MQTTPubRecSend	The library will send a PUBREC for a received PUBLISH.
MQTTPubRelSend	The library will send a PUBREL for a received PUBREC.
MQTTPubCompSend	The library will send a PUBCOMP for a received PUBREL.
MQTTPubAckPending	The library is awaiting a PUBACK for an outgoing PUBLISH.
MQTTPubRecPending	The library is awaiting a PUBREC for an outgoing PUBLISH.
MQTTPubRelPending	The library is awaiting a PUBREL for an incoming PUBLISH.
MQTTPubCompPending	The library is awaiting a PUBCOMP for an outgoing PUBLISH.
MQTTPublishDone	The PUBLISH has been completed.

Packet types used in acknowledging QoS 1 or QoS 2 publishes.

Enumerator
MQTTPuback	PUBACKs are sent in response to a QoS 1 PUBLISH.
MQTTPubrec	PUBRECs are sent in response to a QoS 2 PUBLISH.
MQTTPubrel	PUBRELs are sent in response to a PUBREC.
MQTTPubcomp	PUBCOMPs are sent in response to a PUBREL.

The status codes in the SUBACK response to a subscription request.

Enumerator
MQTTSubAckSuccessQos0	Success with a maximum delivery at QoS 0 .
MQTTSubAckSuccessQos1	Success with a maximum delivery at QoS 1.
MQTTSubAckSuccessQos2	Success with a maximum delivery at QoS 2.
MQTTSubAckFailure	Failure.

Return codes from MQTT functions.

Enumerator
MQTTSuccess	Function completed successfully.
MQTTBadParameter	At least one parameter was invalid.
MQTTNoMemory	A provided buffer was too small.
MQTTSendFailed	The transport send function failed.
MQTTRecvFailed	The transport receive function failed.
MQTTBadResponse	An invalid packet was received from the server.
MQTTServerRefused	The server refused a CONNECT or SUBSCRIBE.
MQTTNoDataAvailable	No data available from the transport interface.
MQTTIllegalState	An illegal state in the state record.
MQTTStateCollision	A collision with an existing state record entry.
MQTTKeepAliveTimeout	Timeout while waiting for PINGRESP.

MQTT Quality of Service values.
