Configuring data transmission over the MQTT protocol

To configure data transmission over the MQTT protocol:

1. Create the MqttPublisherSettings-0.json file.
2. In the MqttPublisherSettings-0.json file, specify the MQTT settings and their values in accordance with JSON syntax.
3. Put the configuration file into the directory /app/Core/config/transfer/mqtt/publisher on the HW-IDS partition of the microSD card.

Sample configuration file:

MqttPublisherSettings-0.json

{

"id": 0,

"name": "Kaspersky IoT Secure Gateway 100 MQTT Publisher",

"description": "Transfer data to MQTT Broker by Kaspersky IoT Secure Gateway 100",

"clientId": "KISG100",

"serverUri": "ssl://192.168.188.8:8883",

"security": {

"clientPkiData": {

"certificate": "mqtt-publisher.crt",

"privateKey": "mqtt-publisher.key"

},

"trustStore": ["ca-bundle.crt"]

},

"userCredentials":{

"username": "KISG100",

"password": "4vRXE84zsCy8bLQcZi2HH82TmC"

},

"lastWill": {

"topicName": "LastWill",

"message": "LastMessage"

},

"keepAlive": 800,

"qualityOfService": 1,

"topics": [

{

"id": 0,

"name": "Heartbeat",

"topicName": "Heartbeat"

},

{

"id": 1,

"name": "Temperature",

"topicName": "Temperature"

},

{

"id": 2,

"name": "Speed",

"topicName": "Speed"

}

]

}

To edit files in JSON format, we recommend using a text editor that supports JSON syntax highlight. This will help avoid potential errors (for example, unbalanced braces).
