Automatic update function

In each previous version release, users can jump to the latest version download page through the download button in the upgrade prompt box, and manually download the installation package to complete the software update. Starting from v1.8.1, users no longer need to download and install manually, just click the button after receiving the upgrade prompt, and the software background can automatically upgrade the version to the latest. The automatic update function allows users to experience the latest functions faster and improve the user experience.

After the update is complete, you can view the latest release log in the pop-up box to quickly understand the update content of the current version and improve the user experience.

Default MQTT 5.0 connection

In previous versions, MQTT X defaulted to MQTT 3.1.1 connections. As the most complete MQTT client tool that currently supports MQTT 5.0 features, we have modified the MQTT version of MQTT X default connection to 5.0 in the latest version, so that more users can quickly use and experience the new features of MQTT 5.0.

Validate topics before publishing

When a user sends a message to a topic with wildcard characters such as + and #, the connection will be disconnected. Many new users will often encounter such problems when they do not understand the MQTT protocol, resulting in disconnection and use. doubts. In version 1.8.1, in order to avoid such a situation, we verified the Topic before publishing. Only when these Topics that do not contain wildcards are used during publishing, the publishing can be successful.

MQTT X CLI

MQTT 5.0 support

MQTT X CLI 1.8.1 has now completed the connection support for MQTT 5.0, and uses the MQTT 5.0 connection by default when using it. At the same time, a new user attribute parameter --user-properties is added, which supports setting user attributes when connecting, publishing, and subscribing. E.g:

 mqttx pub -t 'hello' -h 'broker.emqx.io' -p 1883 -m 'from MQTTX CLI' -up "name: mqttx" "company: EMQ"

Added conn command

In the current version 1.8.0, only two commands, pub and sub, are supported, that is, fast publish and subscribe. For some simple scenarios that only need to test the connectivity of the MQTT service, the conn command is more convenient.

 mqttx conn -h 'broker.emqx.io' -p 1883 -u 'admin' -P 'public'

MQTT X Web

The current online address of MQTT X Web has been modified to: http://www.emqx.io/online-mqtt-client

Just visit the above address, you can quickly use this online MQTT 5.0 client tool, connect to MQTT Broker through MQTT over WebSocket and test message publishing and receiving in the browser, and quickly develop and debug your MQTT services and applications.

In version 1.8.1, the page style has been optimized, and the testing function has been improved. In the future, we will continue to improve the attribute configuration function of MQTT 5.0.

Fixes and optimizations

In addition to adding the above new features, this update also fixes many known issues and further improves stability.

• Fix the pop-up reminder that MQTT X quit unexpectedly in macOS system
• Fix the style problem when MQTT X displays user attributes in the message list
• Fix the invalid --clean parameter under MQTT X CLI, use --no-clean parameter instead

future plan

MQTT X is still in the process of continuous enhancement and improvement, in order to bring more practical and powerful functions to users and facilitate the testing and development of the IoT platform.

Next we will focus on the following:

• User experience upgrade
• MQTT X CLI will support bench command
• Plugin system (e.g. support for SparkPlug B, integration with MQTT X CLI)
• Script function optimization
• Launched MQTT X Mobile mobile application
• Improve MQTT X Web function
• MQTT Debug function
