Everyware Cloud provides an easy mechanism for connecting cloud-ready devices to IT systems and/or applications; therefore, connecting to Everyware Cloud is an important step in creating and maintaining a complete M2M application. Information on Everyware Cloud and its features can be found here. This document outlines how to connect to Everyware Cloud using the Kura Gateway Administrative Console.

Using the Kura Gateway Administrative Console

The Kura Gateway Administrative Console exposes all services necessary for connecting to Everyware Cloud. The reference links listed below outline each service involved in the Everyware Cloud connection. It is recommended that each section be reviewed.

CloudService

The default settings for the CloudService are typically adequate for connecting to Everyware Cloud. The screen capture shown below displays the default settings for the CloudService. For details about each setting, please refer to CloudService.

DataService

The majority of default settings in the DataService can be left unchanged. A screen capture of the DataService configuration is shown below. For complete details about the DataService configuration parameters, please refer to DataService.

In order for Kura to connect to Everyware Cloud on startup, the connect.auto-on-startup option must be set to true. If this value is changed from false to true, Kura will immediately begin the connection process. It is recommended that the CloudService and MqttDataTransport are configured before setting the connect.auto-on-startup option to true.

Note:

Changing the value of connect.auto-on-startup from true to false will not disconnect the client from the broker. This setting simply implies that Kura will not automatically connect on the next start of Kura.

MqttDataTransport

While the majority of default settings in the MqttDataTransport can be left unchanged, the following parameters must be modified:

  • broker-url - defines the MQTT broker URL that was provided when the Eurotech Everyware Cloud account was established. Information on how to obtain the broker URL can be found here. In the MqttDataTransport configuration screen capture shown below, the broker-url is mqtts://broker-sandbox.everyware-cloud.com:8883/ or mqtt://broker-sandbox.everyware-cloud.com:1883/

  • topic.context.account-name - defines the account name of the account to which the device is attempting to connect. In the MqttDataTransport configuration screen capture shown below, the account name is ec-account-name.

  • username - identifies the user to be used when creating the connection. In the MqttDataTransport configuration screen capture shown below, the username is ec-account-name-broker.

Note:

When connecting to Everyware Cloud, the username must have proper permissions. Information on users and permissions can be found here.

For complete details about the MqttDataTransport configuration parameters, please refer to MqttDataTransport.

Connect/Disconnect

The status panel can be used to manually connect or disconnect the client while Kura is running. The main button toolbar has a connect and disconnect button that may be used to control connectivity.

Note:

Connecting or disconnecting the client via the status panel has no impact on Kura automatically connecting at startup. This capability is only controlled via the connect.auto-on-startup DataService setting.
