The broker works as expected, I used mqtt explorer for it. It "sees" all unencrypted topics/traffic (many of which codesys ;-) ).
I will incorporate a pre configured send and receive MQTT framework into our project/library.
I used the "MQTT Clien SL Example" provided by "IIoT Libraries SL".
Just set the hostname / ip to: broker.hivemq.com
Port is allready set at 1883.
