WIZ110SR UDP SERVER PORT PROBLEM

Question

Hi Good Days, I have a lot of WIZ110SR, and I use them in Tcp / ip to Serial mode without any problems. but I am having a problem under “Use Udp Mode”. I want to make the UDP server port random. local port is 161 all time. So if I get data from the any port to the PC den WIZ110SR, I want to send the data to that port. wiznet local port = 161. server port is 60542 ==> wiznet 161. port / wiznet 161.port ==> 60542 same time. server port is 1528 ==> wiznet 161. port / wiznet 161.port ==> 1528 Also, Wiznet 110sr send udp packet only 1 byte , ı send on serial 10 byte packet but only udp send 1 byte to 1 byte, so wireshark mal formed packet read.

Hi, Sorry for the late reply. What is the firmware version of the module? I don’t understand that socket is created with 161port. This is the log of udp communication with v5.13 version. image623×525 11.9 KB image623×525 10.1 KB “Wiznet 110sr send udp packet only 1 byte …” This can be the case when the module captures serial data and sends it to Ethernet. To prevent this, set the option. image965×566 25.9 KB
