Simcom 900d-ftp

[pedja089]

I have a Simcom 900D with firmware 1137B06SIM900M64_ST, that supports FTP.
Here is HTTP/FTP AT Command list
4992
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 :confused:
I managed to send file like this:
