I need help to send data packets on Ethernet but i want to broadcast it to all the other device on network. For now i want to send hardcoded data which later could be changed. In STMcubeMx i've checked Ethernet, RCC and SYS. Do i need to add any middleware for Layer 2 broadcast? I'm confused with all the API's provided and couldn't figure out a proper way to do it. I'm using STM32F2207ZG(Nucleo-144). Any sort of help is appreciated. Thank You.
