I am trying to create PubSub setup in UAExpert, using UACpp server as Publisher. Below are the steps I performed:
1. In UaExpert, added WriterGroup and Writer to publish data for /Objects/2:Demo/2:Static/2:Scalar/2:Int16.
2. Exported the configuration file from UaExpert and copied it to 'pubsubconfig.bin' in UACpp server bin folder and restarted the server.
3. Subscribed to the Publisher topics using MQTT client.
However, I did not receive any messages on MQTT client. Please let me know if I am missing something in the Publisher setup.
I am using UaCpp version -
Unified Automation UA SDK C++ Server Professional 1.7.0 (Binary Edition)
UAExpert version ->UAExpert 1.6.1.424

Re: Facing issue in Publishing data using UACpp as publisher in UAExpert
Hi,
we have tested the publishing in CppDemoServer, it works like a charm.
Please contact the provider of your MQTT Client/Subscriber software, there seems to be some implementation bug or missing functionality when subscribing to the OPC data. Most probably the MQTT Client is not capable of understanding the highly compact UA-Binary encoded data (must implement in MQTT Client).
