It’s the first time I use so a module.
After configuration with S2E V1.4.0 and WIZ750SR-EVB (TTL-RS232) the module worked as expected.
A few hours after functioning without problem in my project, it no longer works and only the red led is still on.
So I put it back on the EVB and there no longer any response. It seems that he has lost all his configuration. On the S2E, it’s no longer detected either with the IP address I gave it or the factory one. No message on the debug port either.
An idea ?
