Over the last months basysKom contributed a number of improvements to the OpenAPI Generator project. OpenAPI as a standard provides a structured way to define, implement, test and maintain REST-like APIs.
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.
Companion specifications complement OPC UA with the goal of fostering interoperability. This article will provide an overview about implementing a Companion Specification with open62541.
So far programs using Qt OPC UA with the open62541 back-end produced quite a bit of chatter on stdout originating from the open62541 stack itself. Unfortunately there was no simple way to get rid of these low-level logs. We now provide a way to control this behavior.

In this blog post, I will explain how you can implement this feature in Qt Versions prior to 5.15.
