Mqtt Client Globe

Mqtt client receives and sends messages from MQTT broker

• Receives messages in the background when the application is not running

• Works with multiple servers and has message filtering by topic

• Keeps the history of sent messages and allows them to be re-sent

• Generates notifications

• Highlights messages with the same topics

• Can group messages with one topic. Only the last message will be displayed

Setting:

1. To add a server, click "+" in the settings window

2. Specify the path to the broker, for example: "tcp: //192.168.1.1"

3. Specify the port: "1883"

4. If the broker is password protected, then specify "Login" and "Password"

5. Enter topic and press "+". The topic is specified in the format "name / #", where # is any port

6. Turn on "Notifications" to display pop-up messages from the broker

7. Press the "Restart" button to restart the service

Sending a message:

1. Select the type of delivery:

a) "QoS 0" - the publisher sends a message to the broker once and does not wait for confirmation from him

b) "QoS 1" - the message will definitely be delivered to the broker, but there is a possibility of duplicate messages from the publisher. The subscriber can receive multiple copies of the message

c) "QoS 2" - at this level, delivery of messages to the subscriber is guaranteed and possible duplication of sent messages is excluded. Each message has a unique identifier

2. Enter a topic, for example: "t10 / cmd"

3. Enter a message, for example: "{port: 10, value: 1}"

4. Click "Submit"

The message can be selected previously sent by clicking on it.

Filtering messages:

1. Enter a topic separated by a space, for example "t14 t15"

2. The data will be immediately filtered

3. If you press the "Filter" button, the filtering will be disabled.
