Description
Gateway
settings
Gateway
prefix
Identifies the device. By default, this is the Hardware ID of
the device.
Basic
MQTT
Version
MQTT version to be used (depending on the MQTT broker).
Keep Alive
Interval
Defines the maximum length of time in seconds that the
broker and client may not communicate with each other.
Username
User name for authentication at the broker (if implemented
and required by the broker).
Note that the
mosquitto
broker from the netFIELD Portal does
not require login authentication.
Password
Password for authentication at the broker (if implemented
and required by the broker).
Note that the
mosquitto
broker from the netFIELD Portal does
not require login authentication.
Connect
Timeout
Defines the maximum length of time in seconds that is
allowed for completing the connection process.
Clean session If
Clean session
is selected, the client does not want a
persistent session (meaning that if the client disconnects for
any reason, all information and messages that are queued
from a previous persistent session are lost.
If
Clean session
is unchecked, the broker creates a
persistent session for the client.
Server URIs
Server URI or FQDN of the MQTT broker
Note
: When multiple server URIs are specified, the client will
try to connect to each server one after the other, starting with
the first server in the list.
If a server connection was established successfully, only this
connection will be used. The client will not open multiple
connections to multiple servers simultaneously.
Last Will and Testament
Select this option if you want to use the “last will and
testament” (LWT) feature of MQTT. (I.e. to notify other clients
about an unexpected loss of connection to the broker)
Topic Name
Topic name of LWT message
Retained
“Retained” flag of LWT message
Quality of Service
QoS of LWT message
Message
Message text, e.g. “unexpected loss of
connection”
SSL / TLS
Select this option if you want to use SSL/TLS encryption for
creating a secure connection to the MQTT broker.
Note
: This option is for expert users only! In the standard use
case, in which the
mosquitto
broker and the Docker
containers are running on the same device, a secure SSL/
TLS connection is not necessary (the overhead of the secure
connection can thus be avoided).
File name and path
to private key in
PEM format
Enter here the complete path to the
private key on the device.
File name and path
to certificate chains
in PEM format
Enter here the complete path to the
certificate chains on the device.
Override the trusted
CA certificates in
PEM format
Enter here the complete path to override
the trusted CA certificates on the
device.
Enable verification
of the server
certificate
If this option is disabled, the Docker
containers will also accept invalid
certificates from the broker (not
recommended).
