The B4R rMQTT library is based on the well known Arduino PubSubClient library written by Nick O'Leary. It's a subset of this library - with the most important/used methods wrapped. I do have a scenario that requires some of the additional methods to be wrapped as well. Specifically: boolean...

Having been away from micro-controllers for much of the year (my have things changed!), I will admit that I was puzzled by references to FreeRTOS and ESP32. I never payed much attention to it as when you compile a sketch in Arduino or a B4R program - *it just works*. I originally got started...
