There are two errors in the “Establishing an FTP Client with a WISMO Module” application note:
1: page 2, in the example table row 8,
there should be “AT+WIPCREATE=3,2,2861,2,3” instead of “AT+WIPBR=3,2,2861,2,3”
2: page 2, in the example table row 9,
again “AT+WIPCREATE=2,1,”",21" instead of “AT+WIPBR=2,1,”",21"
For me this appnote works only until I connect to the FTP server. After the welcome message from the server I try to log in by typing in the user FTP command like this: USERmy_user_name. No matter if I use correct or wrong user name, or I type in any character sequence, I get no reaction from the server at all. The server only closes the connection after 60 seconds timeout. With FileZilla client I can connect to the server without problems.
This is what I get:
at+wipcreate=3,2,2861,2,3
OK
at+wipcreate=2,1,“my_ftp_server_url”,21
OK
+WIPREADY: 2,1
+WIPDATA: 2,1,35
at+wipdata=2,1,2
CONNECT
220 ftp_server_IP_address FTP server ready
421 Login Timeout (60 seconds): closing control connection.
SHUTDOWN
+WIPPEERCLOSE: 2,1
OK
Any advice on what I am doing wrong would be welcome.
