Error in Appending data to FTP file in Online mode

  1. Hello,

              I am using telit GL868 2G modem  based on GSM/GPRS, & i am using GPRS for ftp data transfer.

     

             I am trying to uplaod 2MB file on ftp server in append file mode using Online mode.

    1. At a time i write 1024bytes to serial port of modem

    2. then give delay of apprx 1 sec

    3. and repeat steps 1& 2 until complete file gets uploaded.

     

             But when i check my ftp file on server, it is around  200-300KB only. so what is wrong with my logic?  OR are there any parameter settings required using AT command?

     

            Can some one help me with code?

     

    Thanks in advance..

  2. The only way to ensure consistent data transfers is to use hardware flow control, no delays based strategy can provide this.
