    Default Simcom 900d-ftp

    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:
    Code:
    AT+CGEREP=1
    
    OK
    at+cipmux=1
    
    OK
    AT+CREG=1
    
    OK
    AT+CGREG=1
    
    OK
    AT+CGATT=1
    
    OK
    AT+COPS?
    
    +COPS: 0,0,"YUG 03"
    
    OK
    AT+CSTT="gprsinternet","mts","064"
    
    OK
    AT+CIICR
    
    OK
    AT+CIFSR
    
    172.30.7.93
    AT+CIPSTART=0,"TCP","ftp.****.com",21
    
    OK
    
    0, CONNECT OK
    
    +RECEIVE,0,322:

    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
