21 3.1.0 and 3.1.1. The Zephyr MQTT implementation can be used with either plain
25 MQTT clients require an MQTT server to connect to. Such a server, called an MQTT Broker,

13 MQTT-SN is a variant of the well-known MQTT protocol - see :ref:`mqtt_socket_interface`.
15 In contrast to MQTT, MQTT-SN does not require a TCP transport, but is designed to be used

22 1.2. The Zephyr MQTT-SN implementation can be used with any message-based transport,
25 MQTT-SN clients require an MQTT-SN gateway to connect to. These gateways translate between
26 MQTT-SN and MQTT. The Eclipse Paho project offers an implementation of a MQTT-SN gateway, but

18 - Publishing temperature sensor data in JSON format to the MQTT broker at a user-defined interval
