Simcom 900d-ftp

[pedja089]

I have a Simcom 900D with firmware 1137B06SIM900M64_ST, that supports FTP.
Here is HTTP/FTP AT Command list
an_sim900_ip_application note_v1.00_draft.pdf
But no matter how I tried to send a file, always get a net error. The same error also with http.
I don't understand how to use the AT + SAPBR
I managed to send file like this:

But not using FTP commands.
Does anyone know how to send the file to the ftp using ftp command, or has some advice, suggestion?
Thanks
