send Ip fragmentation for UDP

I wanted to send data larger than 1500 bytes in UDP. I do not require to receive, Is there a way in W5300 to do this? Currently it is shared as separate UDP packet.

Hi,

In the case of UDP, if the data size of the incoming packet exceeds 1,472byte, it will be recognized as wrong data on our chip. It is recommended to split it into 1024 bytes per packet and send data to the chip.

Thank you.

I want to send data from W5300. Not incoming. How to send using IP fragmentation.
