SENDING POPUP #

WHAT YOU NEED

• Being connected to the MQTT Broker

• Your MQTT Publishing Topic looking as follows: psa/OVIPPartners-Dev/from/uid/{UID}/opa/{VIN}/

SENDING NOTIFICATIONS (POPUP) #

The Notification message or popup lets you display a modal window on the NAC in order to redirect the user’s attention over a precise action or information

This notification will be displayed regardless of the current active module (Navigation, Media, …) and thus isn’t limited to the NAC’s Web module.

The user is able to:

• Press the OK button. See okBtn event.
• Press the Return arrow to the top left. See cancelBtn event.
• Not do anything, in which case the window will close automatically after 15 seconds. See closeTimeout event.

The action done by the user is transferred to the embedded Application for it to react accordingly.

IMPORTANT #

Caution: Popups (either MQTT or nativePopup) must not be asked more often than once every 20 seconds.

Caution 2: Navigation.LaunchGuidance() and Navigation.LaunchGuidanceWaypoints() can not be launched when a popup (either MQTT or nativePopup) is displayed. To make sure the guidance have actually been launched please check that LaunchGuidance function return is True.

HANDLING POPUP #

var targetVin = "0123456789ABCDEFG"; // VIN is an alphanumeric string of 17 characters
var mqttPublishTopic = `psa/OVIPPartners-Dev/from/uid/${mqttConfig.username}/opa/${targetVin}`;
var payload = {
	"idApp": "MY_APP_ID",
	"popup": true,
	"popupText": "You have a new message"
};

var mqttMessage = new MQTTMessage();
mqttMessage.payload = JSON.stringify(payload);
mqttMessage.qos = 1;

mqttClient.publish(mqttPublishTopic, mqttMessage);

Note: the max size for a MQTT message is 128 Kio
