Hi Cigdem, Hi Anthony, Hi Paul,

Why are you using the term MQTT broker? My understanding of the MQTT spec is that there are only clients and servers - nothing more.

Is a MQTT v3.1.1 client able to talk to a MQTT v5 server? Would a MQTT v3.1.1 client talk to a MQTT v5 client via a server that supports both v3.1.1 and v5?

Ciao
Hannes
