CA certicate MQTT2_CaCertFile Name of the certicate used to
authenticate the specied MQTTS
server. The certicate is to be retrieved
from your MQTTS server and must be
imported to the concentrator by FTP or
by the web interface.
Client Id MQTT2_ClientId Customizable identier of the equipment
on the MQTTS server.
This parameter is to be retrieved from
your MQTT server.
Keepalive (s) MQTT2_KeepAlive If no exchange has been made with the
MQTTS server for the time dened in
seconds, the concentrator sends a ping
to the MQTTS server in order to verify the
connection to it.
If the value is “0”, KeepAlive is disabled.
If the hub is in permanent connection
mode with the MQTTS server and
a disconnection is detected after a
KeepAlive, the hub will automatically
reconnect to the MQTTS server.
Client Id MQTT2_Topic Name of the topic for the data deposited
by the concentrator.
Data qos MQTT2_QoS Guaranteed service number for sending
messages (Quality Of Service). The
possible values are:
•0: The message will be delivered at
most once, i.e. with no guarantee of
reception.
•1: The message will be delivered at
least once, i.e. the concentrator will
transmit several times if necessary until
the broker conrms that it has been
transmitted.
•2: The message will necessarily be
saved by the concentrator and will
always send it as long as the broker
does not conrm its sending. (avoids
duplication of messages)
