How can I fix the CONNECTION_REFUSED error in my STM32 Nucleo H743ZI2 MQTT setup?
Hey guys could anyone assist me with setting up MQTT communication on my STM32 Nucleo H743ZI2? I need to establish MQTT communication over TCP/IP with another STM32 device. Currently, I am using the standard MQTT library from LWIP, but I am open to alternatives like the PAHO library or others. I can only achieve a TCP connection but get a CONNECTION_REFUSED error when attempting MQTT. I've verified network configurations and broker details. Any guidance or examples would be greatly appreciated. @Middleware & OS
