In this blog we explain how to provide OPCUA open62541 as a ffi plugin to Dart and use it in Flutter. We highlight the pros’ and give you the cons.
basysKom recently extended this plugin to also accept PEM-based input. PEM is a file format used for certificates and keys which is specified by an RFC and is a preferred format for a lot of open source software. The pull request has been merged and our contribution is available from the 1.1 branch (and will also hit the master branch soon).
In this blog we will cross compile Flutter for a generic ARMv7 Embedded Linux target. We will prepare the sdk, compile flutter and in the end run some demos.
The open62541 OPC UA stack with its Pub-Sub extension now supports MQTT over TLS as well as MQTT-brokers requiring a login (contributed by basysKom). This allows the direct communication between open62541 and the Azure IoT Hub and therefore highly simplifies the connection of OPC UA based IoT Devices to the cloud.
The Device Provisioning Service is a managed service running in the Azure cloud which supports automatic provisioning of IoT devices for IoT Hub.
The following sections will give a short introduction to the most important features of the Device Provisioning Service.
In the third part of our series, we show how Protobuf messages from the IoT Hub can be processed in Azure Functions.
Protobuf is a great choice to transfer data from a IoT device into the cloud. This blog will show you what Protobuf is, how it can be used with C++ and Javascript and how to handle updates without breaking backwards compatibility.
In the first part of our series, we will connect a Qt app to the Microsoft Azure IoT Hub, use the Device Twin and show you how to authorize your IoT device to the cloud.
IoT and IIoT applications are special compared to other kinds of cloud applications as they have to deal with devices existing “outside” of data centers.
The following series of articles provide an end-to-end overview of what Microsoft Azure offers to handle some of the challenges involved in connecting an IoT Device with the Cloud.
By working through this series you will learn about the major concepts involved in getting your IoT/IIoT device connected to Microsoft Azure. In our examples we will feature Qt, Node.Js, Protobuf from Google and much more to get you started.
