Welcome to the wolfSSL Forums. Yes, wolfMQTT sounds like a great fit for your project!

We have lots of example projects in the library. I'm not sure what you mean by "manual work to handle incoming messages". The client subscribes to a topic and messages are received.

Could you tell us a bit about your MQTT project and where you are located for our support records?

Thanks,
Eric - wolfSSL Support

I've tried https://github.com/eclipse/paho.mqtt.embedded-c but looks it hasn't been updated for 6 years. Also does not support version 5.

I also found https://github.com/wolfSSL/wolfMQTT slope game which looks good but it looks like it requires some more manual work from the user to handle incoming messages.

Has anyone tried wolfMQTT?

Any other libraries?

I want it for microcontrollers like Cortex-M0/0+/3/4 in C.
