Announcing the umati Dashboard-OPC UA-Client

The umati community did its first open source release of the “umati Dashboard OPC UA Client”. To support this effort basysKom has worked with the umati community and ported the client to the open62541 OPC UA stack.

Qt OPC UA: Logging improvements in Qt 6.1

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.

Qt OPC UA updates

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 support, thus removing the dependency on mbedTLS.

Support for PEM in the open62541 OpenSSL plugin

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).

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.

Building Qt OPC UA with open62541

Qt OPC UA is not included in the Qt installer and must be built from source. The open62541 backend is currently the most stable and feature
