IoT Plug and Play enables solution builders to integrate IoT devices with their solutions without any manual configuration.
It introduces a model as a public description of a device. This device model advertises the capabilities of the logic on your IoT device like telemetry, properties, and commands. These elements are bundled as an interface. These interfaces are described using the Digital Twins Definition Language (DTDL).
Implementing IPnP in your solution is not that hard. The Azure IoT Device SDKs have you covered. Just interact with the cloud as usual. Only, when setting up the connection, the device exposes a ModelId. This id is compared with public models available in a repository so the actual model can be restored.
Next to direct-internet-connected devices, Azure IoT also support this concept of edge compute:
The way Azure IoT Edge devices are connected to the cloud differs quite a lot.
Azure IoT Edge devices lack the support for a ModelId. So there is no direct reference to any model is a model repository. But each type of edge device comes with a Deployment Manifest, describing the logic to be rolled out on the edge device and related settings.
These differences have an impact on how to implement IoT Plug and Play device templates.
Let’s see how to get started with IPnP for edge devices in IoT Central.Doorgaan met het lezen van “IoT Plug and Play support for Azure IoT Edge devices in IoT Central”
