Hi all,

I'm using the demo application of Siemens about MQTT https://support.industry.siemens.com/cs/ww/en/view/109748872. the publishing works normally, but when I enable subcribe, the received topic automatically change to the publish topic i've just used. So does it means that, at a time, the publish topic and received topic must be the same?.

I've seen the documentation, but it seem that there is difference between the publish topic and subcription topic.

Can someone help me? thanks.
