MQTT Messages

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
  • PUBREQ
  • 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.
