Adding an array to your ModuleTwin desired properties

The IoT Modules can be modified using the Azure portal. Microsoft provides two methods to change modules ‘over the air’:

1. Module Identity Twin
2. Direct Method

Direct methods have a name, payload, and configurable connection and method timeouts. Direct methods represent a request-reply interaction with a module.

The Module Identity twin is simply a JSON document which contains information about the module: tags, desired properties, and reported properties.

In this article, we focus on the Module twin and especially the desired properties.

Most examples show how to pass a simple value (like an integer value or a string).

But what if we want to pass an array?

How to give a friend full access to Azure Accelerators

Microsoft is providing multiple solutions regarding IoT. If you want to do everything yourself, go for the PaaS services. If you have no programming skills at your disposal, go for IoT central which is a full SaaS solution for IoT.

But if you have skilled programmers in your team and you want to use the full power of Azure IoT, look at the Azure IoT solution accelerators (fka Azure IoT Suites).

There are several accelerators:

At this moment, Microsoft provides five accelerators. One is built by partner Intel (Intel Connected Logistics platform). One is just a simple one for starting to generate lots of telemetry messages (Device Simulation).

The other three are platforms built by Microsoft themselves and these are a great starting point to start building your own IoT platform.

For example, let’s look at the Connected Factory platform. You can create it within fifteen minutes:

Just let a wizard create the resources in your own subscription:

And then you have a running solution.

Do you want to change it? The code and ARM templates of this Connected Factory accelerator can be found on Github.

The same goes for the other accelerators!

For me the most tricky part is something trivial: how do I give a colleague access to these raw diamonds?
