How can I access an external server using CubeMx and LWIP on STM32F4xx? I don't want it to be a web server, but to access a certain IP from another machine and send a message to it. Are there any examples available?

Hello @erisson​ ,

Sorry, but I did not well understand your need.

Otherwise, Take a look at this example provided under our F4 Firmware Package ( Path : Projects\STM32469I_EVAL\Applications\LwIP\LwIP_TCP_Echo_Client)

Maybe this could help you.

BeST Regards,

Walid

That's exactly what I was looking for.
