Hello @voyvoda .,I tried to connect to MQTT server using LWIP protocol from STM32F4. I am able to connect but getting authentication failure in MQTT server side. And, not able to publish the date to the server. Kindly help resolve this issue.

I configured ethernet and LWIP stack using stm32cubeMX and now I need to include MQTT protocol to my application. How can I include it to my application?

Thank you for your response.I have ethernet and lwip software written in Standard Library in IAR Workbench that is working fine. but when i configure using stm32cube ide, i'm not getting it working.In IAR, ETH_InitStructure.ETH_AutoNegotiation = ETH_...

Hi, I am new to MQTT and LWIP. I am trying to implement MQTT client in STM32F407 and t connect to MQTT server through LWIP. When I tried connecting to MQTT server, I received authentication error in server side. Kindly help resolve the issue.

With stm32f407zet6 controller, I am already using Modbus tcp/ip communication, currently I have added a GitHub code (share from community) to enable MQTT to my existing code, but I am not able to communicate with the broker.

In stm32f407 I configured ethernet and LWIP stack. How to configure MQTT stack using IAR?

I configured Ethernet and LWIP on STM32F407 using cubeMX. Ethernet receive interrupt has come. But callback functions are not called. So I defined the macro "#define USE_HAL_ETH_REGISTER_CALLBACKS 1". Now, I'm receiving a linker error as shown.

I configured ethernet and LWIP on STM32F407 as follows. But I'm not able to ping it and ethernet interrupt is not coming. Kindly help me resolve this issue.

Re: I started using stm32f4 for ethernet. Can someone share the example code for ethernet configuration in stm32cube ide?

Re: I configured Ethernet and LWIP on STM32F407 as shown in the screenshots. But I am not able to Ping the IP.
