Thank you for your helping me on previeos questions.

Thank you and next.

As an sample exmple we hAve two side Tcp server and tcp client .

#########TCP Server

W5500+mcu stm32

#########TCP CLIENT

W5500+MCU STM32

IN AVAILABLE METHODE WHEN WE POWER ON MCU OF SERVER WE SHALL BE RESET THE TCP CLIENT FOR CONNECTING TO THE SERVER . In large huge network it is so difficult to go to the local cliens for reseting it.

Is it possible to send a packet before connection establishing between two w5500 to use it for reset client mcu
