IoT.js MQTT Artik cloud demo

This short demo demonstrates a connection to the api.artik.cloud server through an SSL connection.

Step 1 - Initial setup

Register a new account on https://developer.artik.cloud/ and sign in. Build IoT.js with MQTT and TLS enabled (--cmake-param=-DENABLE_MODULE_MQTT=1 --cmake-param=-DENABLE_MODULE_TLS=1).

Step 2 - Registering your device

When signed in click on the Devices button. This will navigate you to the section where you can manage your devices. Add a new device clicking on Add Another device... Select a corresponding device, or if you don't find anything suitable you can create your own type of device, by clicking on the Developers button in the top right corner. Having clicked the button you will see a Dashboard where you can see Device types and you can click on + New to create a new type of device. Select a display name and a unique name for your device. The unique name must be in the format com.your_company.devicename. Having that done, you can continue, and you will be redirected to the next page where you can set your device up. After selecting the correct device, you should give it a name and you are all set.

Step 3 - Filling in the credentials

Click on the device, and a popup will show up. You should generate a device token as it is needed for the authentication. This will be your password property in the MQTT options object. Copy your device ID and device token to the corresponding values in the JS example file, generate a client certificate and a private key for example with OpenSSL, and also set it in the JS file.

Additional information

According to the documentation the data you send must be JSON.stringify-d, and should be in the following format:

var data = {
  "property_name": property_value,
   ...
};

Only one MQTT client can be connected with the same device id simultaneously. A client can publish and/or subscribe to a topic.
