use the recv() function in socket.h to read the data from RX register to your software buffer.

Dear Vien_Huy_Nguyen:
I want to know,When designing the hardware, does the reset pin of the W5500 chip have to be connected to the MCU? Can you not use the reset pin of the W5500? Only four lines of SPI are used. What’s the effect of not using the reset pin of the W5500 chip? Please answer.
Thanks

You have to reset the chip at least once at startup. So yes, you need to connect the RST pin to the MCU.
