Connecting to an Infotainment System

In order to view your SDL app, you must connect your device to a head unit that supports SDL Core. If you do not have access to a head unit, we recommend using the Manticore web-based emulator for testing how your SDL app reacts to real-world vehicle events, on-screen interactions and voice recognition.

Your SDL cloud app will only work with head units that support RPC Spec v5.1+.

Configuring the Connection

Generic SDL Core

To connect to your app to a local Ubuntu SDL Core-based emulator you need to know the IP address of the machine that is running the cloud app. If needed, running ifconfig in the terminal will give you the current network configuration information.

Policy Table Configuration

Once you know the IP address, you need to set the websocket endpoint and app nicknames for your SDL app in the policy table under the "app_policies" section. This will let Core know where your instance of the SDL app is running. The websocket endpoint needs to include both the IP address and port: ws://<ip address>:<port>/.

 "<Your SDL App ID>": {
     "keep_context": false,
     "steal_focus": false,
     "priority": "NONE",
     "default_hmi": "NONE",
     "groups": ["Base-4"],
     "RequestType": [],
     "RequestSubType": [],
     "hybrid_app_preference": "CLOUD",
     "endpoint": "ws://<ip address>:<port>",
     "enabled": true,
     "auth_token": "",
     "cloud_transport_type": "WS",
     "nicknames": ["<app name>"]
 }

Note

The <app name> value in "nicknames" must match the app name value used in Integration Basics when implementing the SDL manager.

For more information about policy tables please visit the Policy Table guide.

Manticore

If you are using Manticore, the app connection information can be easily added in the settings tab of the Manticore web page. Please note that Manticore needs to access your machine's IP address in order to be able to start a websocket connection with your app. If you are hosting the app on your local machine, you may need to do extra setup to make your machine publicly accessible.

Running the SDL App

Once you have a configured instance of Core running, you should see your SDL app name appear in a box on HMI. However, nothing will happen when you tap on the box until you build and run your SDL app.

Once your SDL app is running, either locally in an IDE or on a server, you will be able to launch the SDL app by clicking on the app icon in the HMI.

This is the main screen of your SDL app. If you get to this point, your SDL app is working.
