Writing an FTP server for potpourri's WiFiEsp library
Posted: Thu Dec 01, 2016 4:44 amhttps://github.com/bportaluri/WiFiEsp
I have started writing the class below and, at this stage, I just want it to respond to an incoming ftp request and out put the data to arduino serial monitor.
However the incoming FTP requests are not making it through.
I have tried connecting with Filezilla on port 21 and also via ftp://10.0.0.133:21 in my web browser - I get nothing.
Can anyone tell me what I have done wrong?
Based on the standard WiFiEspServer class(instantiated with port 80) that comes with the library, doing the above should be quite trivial.
It seems that this library only works with port 80 - is that likely?
