  1. Fill in the required fields:

    • Name: Name of this configuration. You can choose any name.
    • ClientID: Client ID, which you can set manually or generate randomly using the button on the right. It must contain characters “a-z”, “0-9”, “_”, “-”, and cannot exceed 128 bytes. It should be in UTF8 encoding and must be unique.
    • Host: Connection address. Start with the protocol prefix (mqtt:// for TCP, mqtts:// for TLS/SSL, or wss:// for WSS) followed by the domain name that accesses the BifroMQ server.
    • Port: Connection port. Choose the appropriate port based on the protocol prefix. Default ports are TCP: 1883, TLS/SSL: 1884, WSS: 443.
    • Username & Password: Enter the username and password you possess, or leave them blank if your BifroMQ installation is for testing only.
    • MQTT Version: Select 3.1, 3.1.1, 5.0

  2. After correctly entering the connection configuration, click 'Connect' in the top right corner to connect to the server.

  3. Subscribe to a topic: Click on the “New Subscription” button in the top left corner and enter the topic in the pop-up dialog box.
