Parameter Type Description
<op_code> Number FTP command request. Allowed values:
• 0: FTP logout; terminates the FTP session by performing a logout.
• 1: FTP login; connects to the FTP server using the parameters of the current FTP
profile (set via AT+UFTP command).
• 2: deletes the file from the FTP server.
• 3: renames the file. This AT command just sends requests to the FTP process.
• 4: retrieves the file from the FTP server.
• 5: stores the file on the FTP server.
• 6: retrieves a file from the FTP server using direct link mode. This command handles
the initial steps of the FTP protocol for retrieving a file; after that it will establish
a transparent end to end communication with the data connection TCP socket via
the serial interface. After the CONNECT result code, the file content will be directly
sent to the serial interface. When the data transfer is completed, the module will
automatically exit from direct link mode (no need to send +++ sequence).
• 7: sends a file to the FTP server using the direct link mode. This command handles
the initial steps of the FTP protocol for sending a file; after that it will establish a
transparent end to end communication with the data connection TCP socket via
the serial interface. After the CONNECT result code, the user can send the file
