more and more its getting difficult to use Arduinos, ESP8266 etc. for IoT applications using ftp. My provider (1&1 Germany) informed me that in the near future no ftp will be supported and I should move to SFTP soon. Sometimes I'm getting error messages like "ftp not available in the moment. please switch to SFTP".
Is there any chance to switch to SFTP? I didn't find anything in this regard.
If its not possible with the arduinos etc. I think it is the end of cheep IoT applications and thousands of makers will not be able to run loggers to load measured data to there home pages.
Is there anybody out there who has realised SFTP with arduino?
