是的，这个插件并不是很好用，尤其是在传入参数的时候，需要将参数先转换为Byte数组才可以。而且控制台一直有报错，好像是代码内部引起的，我的测试环境是UE5.5，你可以先搭建一个MQTT服务器比如NanoMQ,然后用蓝图： createClient → Connection
Yes, this plugin is not very user-friendly, especially when passing in parameters, which need to be converted into a Byte array first. And the console keeps getting errors, it seems to be caused by internal code. My testing environment is UE5.5, you can first set up an MQTT server such as NanoMQ, and then use the blueprint: createClient → Connection
