2. FTP Introduction
FTP (File Transfer Protocol) is an application layer protocol. File Transfer Protocol is a standard Protocol for
transferring files over a network, using the client / server mode. It's part of the Communications Protocol
Application Layer.
2.1Characteristic
A control connection is a communication link established between a client protocol interpreter and a server
protocol interpreter for exchanging commands and responses. A data connection is a full-duplex connection
for transmitting data. The transfer of data can occur between DTP for the server data transfer process and
DTP for the client, or between DTP for the two servers.
2.2The process of Using FTP(S) AT Commands
Step 1: Ensure GPRS network is available before performing FTP(S) related operations.
Step 2: Configure the parameter of PDP context by AT+CGDCONT.
Step 3: Activate the PDP context to start FTP(S) service by AT+CFTPSSTART.
Step 4: Login FTP(S) server by AT+CFTPSLOGIN.
Step 5: Download a file and save to module by AT+CFTPSGETFILE.
Step 6: Use AT+CFTPSABORT abort any FTP(S) operation.
Step 7: Use AT+CFTPSLOGOUT to logout FTP(S) server while finish FTP(S) operation.
Step 8: Deactivate the PDP context to stop FTP(S) service by AT+CFTPSSTOP.
Note: make sure you login to a FTP(S) sever successfully before any other FTP(S) operations.
