I have a device with a W7100A chip on it which I can configure with the “WIZ107SR / WIZ108SR Configuration Tool” (so I guess it’s basically a WIZ107SR device on a custom PCB).
With the “WIZ107SR / WIZ108SR Configuration Tool” I can successfully configure everything, including the search identification code.
For production I want to have my own tool for configuring the WIZnet chip. I tried to send the following string via UDP broadcast to the device:
I can verify with the “WIZ107SR / WIZ108SR Configuration Tool” that all settings were written successfully, except for the search identification code. As you can see in the string above, I try to set it to “CCMMEI”, but when I read the configuration with the “WIZ107SR / WIZ108SR Configuration Tool” it is empty. What could be the problem here? Is there anything special I need to consider when setting the search identification code?
