Hi @ValdemarLeiras,
Welcome to the Solace Community!
I’m not familiar with OPC-UA, but it looks like it’s own protocol and is not currently supported by Solace Event Brokers. Currently pretty much all of our IoT use cases (that I’m aware of) connect using MQTT so that would be my recommended path forward without knowing more details about your use case. I won’t say that we will never support OPC-UA as a protocol but it hasn’t been highly requested so I don’t see it being added in the near term.
Please feel free to share more about your project, I always love hearing what everyone is building with our technology!
Hope that helps.
