Hey everyone, I want to connect to an MQTT broker and recently learned that Unreal has an official MQTT Plugin, which is experimental. I understand that being experimental means that some things may not work properly, or are subject to change, but the plugin does not seem to work at all. None of t…

I’m also interested in any updates about this plugin.

Just FYI, the issue remains for UE5.3.2. I ended up switching to WebSockets, but it would be nice to have the MQTT protocol working.

I have the same issues. Trying to use it on 5.3.2 but no success.

I tried the plugin and it works. But I can not get the connected callback to fire. [image]

I seem to have found -a- solution though it feels… wrong. It does seem to work though, gets connected then subscribes to the correct topic. Even logs the messages sent to the broker. [Fix]

I have tried the plugin in 5.3.3, with two different brokers (Mosquitto and NanoMQ), and I can’t get it to connect. The brokers complain about parse errors, so it looks like the protocol isn’t implemented correctly? Editor Output Log: LogMQTTCore: Error: Error connecting socket to: 172.104.228.166…

I got the built in MQTT plugin to work with the latest Mosquitto (in both blueprints and c++) - but occasionally the plugin will crash the editor seemingly because it receives an unknown packet type from the broker. I traced the issue to the call to MQTT::GetMQTTPacketTypeName on line 570 in MQTTCo…

Would you be able to provide a little more information about your implementation? I’m very new to UE5 or this type of development, in general, but I’m trying to use MQTT in UE5 to use “real-time” data. The blueprint I tried creating a blueprint based on your image, but I keep getting an infinite loo…

受到上面的启发，可以在mq客户端发送的时候多添加一个空格来解决MQTT插件多删除一个字节的问题，测试后大数据量也不会崩溃了我的代码 [{933489D2-6F37-498f-B133-807187194166}]
