WIZ750SR (PCB Ver1.2; FW Ver1.3.3) has been working fine and I am able to change configuration like IP, Gateway, Port# etc via “WIZnet S2E Configuration Tool v1.3.0”.
In my application, I want to change the configuration parameters through W7500P data port.
I have enabled the serial command mode with default trigger code “+++”.
I am using Hercules setup utility software in my PC for seeing/sending the data on both ends, ethernet as well as Serial.
I can see the data being forwarded to other end is fine. Like, if I transmit any character through serial, I can read it on ethernet side and vice-versa.
For switching the device W7500P in command mode, when I send “+++” on serial, the ethernet link breaks immediately and the device is switching to command mode or ATMODE (verified through “WIZnet S2E Configuration Tool v1.3.0”). But after that I am not able to get any response for any command being sent through serial port.
e.g. command “MA$0d$0a” returns nothing.
