Summary

MQTT (MQ Telemetry Transport or Message Queue Telemetry Transport) is an ISO standard (ISO/IEC PRF 20922) publish-subscribe-based "lightweight" messaging protocol for use on top of the TCP/IP protocol. It is designed to send short messages from one client (publisher) to another (subscriber) through brokers, which are responsible for message delivery to the end point.

RUTX10 devices support this functionality via an open source Mosquitto broker. The messages are sent this way: a client (subscriber) subscribes to a topic(s); a publisher posts a message to that specific topic(s). The broker then checks who is subscribed to that particular topic(s) and transmits data from the publisher to the subscriber.

This chapter is an overview of the MQTT page for RUTX10 devices.

MQTT Broker

The MQTT Broker is an entity that listens for connections on the specified port and relays received messages to MQTT client. To begin using this devices as an MQTT Broker, enable it in this page. In order to make the device accept MQTT connections from WAN (remote networks), you also need to turn the 'Enable Remote Access' slider on.

Field Value Description
Enable off | on; default: off Toggles MQTT Broker between on and off.
Local Port integer [0..65535]; default: 1883 The TCP port on which the MQTT broker will listen for connections.
Enable Remote Access off | on; default: off Turns remote access to this MQTT broker on or off.

Broker Settings

Security


The Security section is used to configure TLS/SSL .

field name value description
Use TLS/SSL off | on; default: off Turns the use of TLS/SSL for this MQTT connection on or off.
TLS type Certificate based | Pre-shared key based; default: Certificate based Select type of TLS.
Certificate files from device off | on; default: off When turned on, provides the possibility to use certificate files generated on this device instead of uploading certificate files. You can generate TLS certificates on your device in the System → Administration → Certificates page.
CA File .ca file; default: none Uploads a Certificate Authority (CA) file. A Certificate Authority (CA) is an entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate.
CERT File .crt file; default: none Uploads a server (broker) certificate file. A certificate file is a type of digital certificate that is used by client systems to make authenticated requests to a remote server.
Key File .key file; default: none Uploads a server (broker) key file.
TLS version tlsv1 | tlsv1.1 | tlsv1.2 | Support all; default: Support all Specifies which TLS version(s) is will be supported by this broker.
Pre-shared key based: Pre-Shared-Key string; default: none The pre-shared-key in hex format with no leading "0x".
Pre-shared key based: Identity string; default: none The identity of this client. May be used as the username depending on the server settings.

Bridge


An MQTT Bridge is used for the communication between MQTT brokers. The window of Bridge parameters is presented below.

Note: this table has a coloring scheme to indicate which fields can be seen with different configuration.

Field Value Description
Enable off | on; default: off Turns MQTT Bridge on and off.
Connection Name string; default: none Name of the Bridge connection. This is used for easier management purposes.
Protocol version 3.1 | 3.1.1; default: 3.1 Selects protocol version
Remote Address ip; default: none Remote Broker’s address.
Remote Port integer [0..65535]; default: 1883 Specifies which port the remote broker uses to listen for connections.
Use Remote TLS/SSL off | on; default: off Enables the use of TSL/SSL certificates of the remote broker. If this is checked, you will be prompted to upload TLS/SSL certificates. More information can be found in the Security section of this chapter.
On: Certificate files from device off | on; default: off When turned on, provides the possibility to use certificate files generated on this device instead of uploading certificate files. You can generate TLS certificates on your device in the System → Administration → Certificates page.
On: Bridge CA File .ca file; default: none Uploads a Certificate Authority (CA) file. A Certificate Authority (CA) is an entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate.
On: Bridge CERT File .crt file; default: none Uploads a server (broker) certificate file. A certificate file is a type of digital certificate that is used by client systems to make authenticated requests to a remote server.
On: Bridge Key File .key file; default: none Uploads a server (broker) key file.
On: Bridge TLS version tlsv1 | tlsv1.1 | tlsv1.2; default: tlsv1 TLS version used by the other broker.
Use Remote Bridge Login off | on; default: off Indicates whether the remote side of the connection requires login information. If this is turned on, you will be required to enter a remote client ID, username and password.
On: Remote ID string; default: none Identifier of the remote broker
On: Remote Username string; default: none Username for authentication to the remote broker.
On: Remote Password string; default: none Password for authentication to the remote broker.
Try Private off | on; default: off Check if the remote Broker is another instance of a daemon.
Clean Session off | on; default: off When turned on, discards session state after connecting or disconnecting.

You can also create and manage MQTT topics in the Topics list below the Bridge section. To add a new topic, click the 'Add' button.

You can then configure the newly added topic from the same page.

Field value description
Topic Name string; default: none The name of the topics that the broker will subscribe to.
Direction OUT | IN | BOTH; default: OUT The direction that the messages will be shared.
QoS Level At most once (0) | At least once (1) | Exactly once (2); default: At most once (0) Sets the publish/subscribe QoS level used for this topic.

Miscellaneous


The Miscellaneous section is used to configure MQTT broker parameters that are related to neither Security nor Bridge.

field name value description
ACL File ACL file; default: none Uploads an ACL file. The contents of this file are used to control client access to topics of the broker.
Password File password file; default: none Uploads a password. A password file stores usernames and corresponding passwords, used for authentication.
Persistence off | on; default: off When turned on, connection, subscription and message data will be written to the disk. Otherwise, the data is stored in the device memory only.
Allow Anonymous off | on; default: on Turns anonymous access to this broker on or off.

MQTT Publisher

An MQTT Publisher is a client instance that can send messages to the Broker, who can forward these messages to other clients (subscribers).

Note: this table has coloring scheme to indicate which fields can be seen with different configuration.
