In addition to numerous bug fixes and improved test coverage, the open62541 plugin has been updated to open62541 v1.1 and uses OpenSSL for security support, thus removing the dependency on mbedTLS.

Connect OPC UA with open62541 to MS Azure IoT Hub

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.

IoT: Getting started with cloud and modern IoT and IIoT from scratch

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.
