MQTT TOPIC #

To communicate with your application you need to indicate whom to publish your message to.

Your publishing topic looks as follows:

psa/OVIPPartners-Dev/to/uid/{UID}/opa/{VIN}/

What’s more, your subscribing topic looks like this:

psa/OVIPPartners-Dev/from/uid/{UID}/opa/{VIN}/

Where:

• UID is your login
• VIN is the Vehicle ID Number corresponding to the vehicle the message is destined to.

MQTT CONNECTION #

WHAT YOU NEED BEFORE BEGINNING #

• Your SSL client certificate to secure the connection
• Your credentials: login (UID) and MQTT password

They will be created by PSA and given to you.

WHAT YOU NEED TO DO #

You have to connect to the environment corresponding to your case by using MQTTClient.connect().

2 different environments exist:

• Preprod: iot-partners-preprod.mpsa.com:8886
• Production: iot-partners-mpsa.com:8886

EXAMPLE

const mqttConfig = {
	"uri": "iot-partners-preprod.mpsa.com:8886",
	"sslClientCert": "./mqtt.client.crt",
	"username": "MY_UID",
	"password": "MY_PASSWORD",
}

var mqttClient = new MQTTClient(mqttConfig);
mqttClient.connect();

You are now connected to the MQTT Broker, you can start sending messages to your application.
