FTP Client

The File Transfer Protocol (FTP) is a protocol used to transfer and manage files and folders. Using this protocol, you can send files to the System or read files from it. You can also create and delete folders and rename files or folders on the system.

The following FTP Client options are configurable from the Net_Config.c configuration file:

• FTP Client switch enables or disables the FTP Client service in your application. It is enabled when this value is set to 1. It should be set to 0 when FTP client is not used in your application.

  #define FTPC_ENABLE    1
  

• Response Timeout in seconds is an inactivity timeout. When the FTP Client does not receive a response from FTP Server within this timeout, it aborts the operation.

  #define FTPC_DEFTOUT   10
  

• Passive mode (PASV) enables the passive mode of FTP Client. In passive FTP mode the client initiates both connections (control and data) to the server. This solves the problem of firewalls filtering the incoming data port connection to the client from the server. Default configuration is passive mode disabled.

  #define FTPC_PASVMODE  0
  

Note

• You must also add the FTPC_uif.c user interface module to your project and customize it. This file is in the \Keil\ARM\RL\TCPnet\User folder.
• The FTP client uses two TCP sockets, one control and one data socket. Have this in mind when you are configuring the number of TCP sockets.
• When the FTP client is not enabled, the ARM linker does not link the FTP support modules to your application and thus reduces the code size and memory usage.
