Thingstream MQTT Now plans use the MQTT protocol to communicate and pass data and status between a device and the Thingstream broker.
Each MQTT message sent between a device and the broker uses a message from the plan allowance. The list of supported MQTT messages is found in the table below:
MQTT message types
CONNECT
CONNACK
PUBLISH QoS 0
PUBLISH QoS 1
PUBLISH QoS 2
PUBACK
PUBREC
PUBREL
PUBCOMP
SUBSCRIBE
SUBACK
UNSUBSCRIBE
UNSUBACK
PINGREQ
PINGRESP
DISCONNECT
For example, a device might wish to wake up periodically, connect to the broker, publish some data to a topic at quality of service 1 and then disconnect. This set of actions would consume 5 messages (CONNECT, CONNACK, PUBLISH, PUBACK and DISCONNECT) from the plan allowance. Messages will be billed on last byte sent from the server.
