RAK439 support MQTT?
Hello, I would like to use mqtt protocol with module 439 (WisNodeSPI) and STM32F411 Nucleo.
It's possible? How can I do?
yes, 439 is spi interface wifi module, you can use mqtt in stm32. but if you can use uart interface, 473 is a better parts, it intergrate mqtt protocal in the module, it is easy to use.
@agirolami87 I am not quite sure about it.
