Low level debug or free memory on wio terminal

Hi @RoSchmi,
no not support TLS.
I create a issue on https://github.com/Seeed-Studio/Seeed_Arduino_FS/issues/8 to fox that problem on FS, if they fix I can add also the management of internal spi flash.

Now I’d like to add callback on some internal ftp function (connect disconnect transfer freespace change) do do a monitor of FTP to show on TFT.

Thank again and Bye Renzo
