retained |
BOOLEAN |
Whether the message is a retained message. Set
to TRUE or FALSE.
The default is FALSE. Set to TRUE if
the message for a topic must be held by the MQTT server after delivery
to all currently connected clients, and then delivered to new clients
when they connect to that topic. Each retained message for a topic
replaces the previous retained message for that topic. In this way,
devices can receive the most recent retained message immediately on
connecting to a topic. |

protocol, the host name, and the port. For
example:tcp://myMQTTserver.com:1883
or, if the connection is
encrypted:ssl://myMQTTserver.com:8883
If set, the value of the connectionUrl
property takes precedence over the values of the following MQTT message flow node properties:
