simcom.exavault.com is our server address, you can use your server.
127.0.0.1 is not the one.

syeda amna · Jan 24, 2013

ok. then what will be the value of "AT+FTPSERV= " in case of filezilla server.

How to get rid of this error?? +FTPGET:1,77
:???:

syeda amna · Jan 31, 2013

+FTPGET:1,77 => Operate Error occurs because of incorrect FTP directory format.

Hi, pls use the FTP in your country. The FTP in the sample locates at Shanghai, you could not connect it.
We have a IP application note,
If needed, pls send e-mail to me: echo.wang@haozetech.com
