Uploading to a remote FTP server (GPy + LTE)

[apopka422]

My GPy program generates little text files on the SD card, and I would like to know how I can upload these files to a remote FTP server.

My LTE connection works fine, and my code does not produce errors. I am simply interested in knowing what Micropython libraries are available to perform a file transfer to a remote server. For what it's worth, I'm using a Hologram SIM card, although I believe the nature of my question transcends this, since I am only interested in methods which allow me to implement a file transfer over a working intermet connection.

Thanks. Any code snippets/illustrations are appreciated.
