Dear Sir, we have a project still active where we are still using W3100. We still have many in stock. We’d need to improve our project implementing an FTP Client because we’d need to transfer a data file from the device memory. The question is if in your experience is possible and if we could meet problems. Thanking you in advance.

Hi, peterinstruments.

I think you can implement in the application level.

I attached ftp client sample code. Refer to it.
ftp%5B0%5D.zip (104 KB)

And you could meet problem. I cannot guarantee you must not meet problem but it is not big problem.

Best regards.
