Wir entwickeln plattformunabhängige Applikationen für vielfältige Plattformen. Wir setzen auf Qt, Flutter, Angular, Azure,... . Wir entwickeln Anwendungen im Kontext von Anlagen, Maschinen und Geräten im weiten Feld zwischen Smart-TV, Infotainment, Messgeräten und CNC-Fräsen. Aus Überzeugung setzen wir offene Standards und Open Source für eine nachhaltige Produktentwicklung ein.
Companion specifications complement OPC UA with the goal of fostering interoperability. This article will provide an overview about implementing a Companion Specification with open62541. Continue reading Implementing OPC UA Companion Specifications with o
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 th
Porting a Qt 5 QML application to Qt 6 doesn't have to be difficult. We want to share the issues we had and how we solved them. Look out for your shaders and modules. Continue reading Qt 6: How To port a Qt 5 application at basysKom GmbH.
Something that has traditionally been complicated to achieve in Qt/QML, especially on low end hardware, is high performant list scrolling with complex delegates. This has recently changed. In Qt 5.15, it is as simple as setting the new QML ListView proper
The Qt OPC UA module has been ported to CMake and will be part of Qt 6 right from the first release. 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 suppor
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 c
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. Continue reading How to run Flutter on an Embedded Device at basysKom GmbH.
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 simplif
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 Provisioni
In the third part of our series, we show how Protobuf messages from the IoT Hub can be processed in Azure Functions. Continue reading How to consume Protobuf messages in Azure Functions (Part 3 of 4) at basysKom GmbH.
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. Continue reading Protobu
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. Continue reading Azure IoT Hub: Connecting a Qt Application with Azure (Part 1 of 4)
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 han
For the development of a successful smart product it is important to systematically analyse the benefit and thus also the value of the planned product for the customer. Continue reading Customer-oriented ideas for smart products at basysKom GmbH.
Digital transformation and smart products: The world around us is getting smarter and smarter and the Internet of Things continues to make its way into work and everyday life. And so there is hardly a product in the meantime where a technology-oriented pe
