Hello.
I’m trying to connect with FTP in a RM520N-GL, (RM520NGLAAR01A08M4G), but no QFTP command works. Any suggestions?

I checked the latest version and it doesn’t support FTP

Are there any plans to introduce these commands in a future firmware release? Can the firmware be downgraded to a version that includes them?
Sincerely,
Jaime Luján

At present, there is no plan for the development of FTP function
