Hello,
As you may already know, W5300 has UDP and TCP modes. So we decided to don’t receive UDP, TCP packets in IPRAW mode. If you want receive UDP packet, open socket in UDP mode.
Thank you

Hi~ As far as I know, if you want to use RTSP, you should use TCP. But RTP can use TCP or UDP selectively.
IPRAW data is composed of 6 byte PACKET-INFO and DATA packet. PACKET-INFO
includes sender’s information (IP address) and the length of DATA packet. So, if you use IPRAW mode, UDP packets encapsulated.
Thank you!

Dear Irina
Thank you very much for your reply. No doubt IP layer packet does contain UDP data but hardwired TCP/IP protocol stack of wiznet w5300 does not allow to receive UDP packets using IPRAW communication mode. So I am not able to receive UDP/TCP packets in IPRAW communication mode.
