can somebody help me with my STM32 Nucleo H743ZI2 ?
Hey, can somebody help me with my STM32 Nucleo H743ZI2 ?
I have to configure a MQTT communication to another STM32 over TCP/IP. I use the standard MQTT library from LWIP. But you can show me also from PAHO or another library.
I only get a TCP connection but not a MQTT connection.

@wafa_ath Are you using any firewalls or network security policies that might be blocking the MQTT communication?
I’ve checked, and I'm not using any firewalls or network security policies that might be blocking the MQTT communication. The TCP connection works fine, but I can't seem to establish the MQTT connection. Do you have any other ideas on what might be causing this issue
