If you have multiple gateways you plan to update on a regular basis, you will probably be interested in automating this process.

The LORIX One is compatible with mender, which provides a powerful infrastructure to manage the updates for your devices.


Updating with mender requires two parts:

  • The gateways you want to update
  • A server that will send the update to the gateway

The gateway already has everything needed installed. As for the server, you will need one for your own deployments.

The gateways will contact the server, this means your gateway doesn't need to be accessible from the outside world.

You can find advanced information regarding mender on the official website or on the mender documentation: https://docs.mender.io/. When reading the documentation, please keep in mind that the LORIX is already totally compatible. This means the device side part of the documentation can be skipped.

Setup the server

To setup your server, you have two possibilities:

  1. Hosted mender: subscribe for a server as a cloud service (SaaS)
  2. On premise: install the Open Source or the Enterprise mender server stack on your infrastructure

Subscribe a hosted mender plan

You can find all details regarding the available plans, pricing and features on the mender website.

Install an on premise mender server

Mender server is available in two flavors: the Open Source and the Enterprise version. You can check on they differ in features on the mender website.

The mender software stack is composed of multiple services that run together. Installing it on your servers requires some devops knowledge, particularly to configure the platform correctly regarding security.

All information regarding the installation can be found on the official documentation: https://docs.mender.io/2.5/server-installation/overview.

Register the gateways

Now that you have a running server, you can connect the gateways to the server.

Configure the gateway

The gateway runs the mender daemon that will contact the update server. The daemon must be configured correctly regarding the update server configuration.

Edit the configuration

The configuration is located at /etc/mender/mender.conf. You can use nano to edit the configuration:

sudo nano /etc/mender/mender.conf

    "ArtifactVerifyKey": "/etc/mender/artifact-verify-key.pem",
    "InventoryPollIntervalSeconds": 28800,
    "RetryPollIntervalSeconds": 300,
    "ServerURL": "https://docker.mender.io",
    "UpdatePollIntervalSeconds": 1800
Hosted mender
TenantTokenGet it from https://hosted.mender.io/ui/#/settings/my-organizationThis token is private to your organization. It allows mender to know to which account it should associate the device.
On premise

Set the ServerURL to your own instance URL. E.g. https://update.mycompagny.com.

You can find more details regarding the configuration options in the documentation.

Start the mender daemon

To start the daemon, run:

sudo rc-service menderd start


menderd | * Starting Mender OTA update service ...   [ ok ]

The daemon will automatically contact the server within the configured interval.

Auto start the daemon at boot

To make the daemon start after each reboot, we have to tell the init system:

sudo rc-update add menderd default


* service menderd added to runlevel default

Disable the daemon

If you would like to disable the daemon totally after that, you can run the opposite commands:

sudo rc-service menderd stop
sudo rc-update delete menderd default

The mender configuration is not yet available through the Manager UI.

Accept the device in the server

When the daemon contacts the server, it will be in a "pending" state until it is accepted. You can see the pending devices on this page: https://hosted.mender.io/ui/#/devices/pending.

By clicking on the device, you access the details panel where you can accept the device:

Once accepted, it will be listed in the devices page:

Deploy an update

To deploy an update, these two steps must be done:

  1. Upload the release artifact to the server
  2. Create a new deployment

Upload the release artifact to the server

Load the release page: https://hosted.mender.io/ui/#/releases.

Download the update artifact of the version you want to upgrade to at https://download.wifx.net/lorix-os/. The artifacts are stored in the image folder and have a .mender extension. E.g. https://download.wifx.net/lorix-os/1.1.1/images/lorix-os-1.1.1+ca3d814_lorix-one-512.mender.

Rename the file by replacing the "+" character by a "-" character (special characters are not supported): lorix-os-1.1.1+ca3d814_lorix-one-512.mender → lorix-os-1.1.1-ca3d814_lorix-one-512.mender.

On the release page, click on the "Upload an Artifact" link and drag the file in the upload window. Press upload.

If you have 256MB gateways, upload the 256 artifact in the exact same way.

You will then have the new release available in the Releases page:

Create a new deployment

Load the deployments page: https://hosted.mender.io/ui/#/deployments.

Click the "Create deployment" button:

Select the release to deploy and the device group on which to deploy the release.

On the next pages, configure your deployment strategy. Once validated, you'll see your active deployment on the deployment page:

At this point, the release will be deployed on the gateways within the configured interval in a fully automated manner. The gateways will automatically restart in the new version.

The gateway contacts the server on a regular basis to know if an update is available. To save bandwidth and reduce server load, this is only done every 30 minutes (by default). You can configure this interval in the mender daemon configuration with the UpdatePollIntervalSeconds option.

As the gateway restarts, the packets forwarding is not active and packets will not be received for a few minutes.

If you have coverage redundancy with your gateways, you may want to create two device groups and update them one after the other so you can keep a complete coverage during the updates.

Going further with mender

To learn more about fleet update management, you can check the mender documentation or check their online videos and webinars that cover this subject in depth.
