ftp - 以太网盾arduino上的FTP客户端

我想做一个项目，其中数据保存在SD卡上，然后使用以太网屏蔽，这些数据使用FTP客户端arduino发送到ftp服务器。服务器我有免费托管。

这是来自ftptest的数据服务器：

    Results
    Your server is working and assorted routers/firewalls have been correctly configured for explicit FTP over TLS as performed by this test. However there have been warnings about compatibility issues, not all users will be able to use your server.
    For maximum compatibility, consider resolving these warnings.

如果有人告诉我可以做什么以及我做错了什么？

我可以使用filezilla投放文件，但仅限于文件夹wsalkowski.cba.pl

问题是否无法从ftp客户端arduino访问路径/wsalkowski.cba.pl？也就是说，带有默认SD卡的文件被抛到根文件夹/，它没有权限chmod？

请帮帮我，对不起我的英文
