CC3100 TCP Socket Application

Overview and application details

This is a sample application demonstrating how to open and use a standard TCP socket with CC3100.

Note: This wiki page is only applicable for CC3100-SDK v1.0.0 and upward releases. For documentation on older SDKs' examples, refer corresponding file in <cc3100-sdk-installation-location>\cc3100-sdk\docs\examples\

Usage

• Connect the board to a Windows-PC and configure the terminal-program for seeing the logs - [| CC31xx_&_CC32xx_Terminal_Setting_Wiki] has detailed instructions for configuring the terminal-program
• Edit sl_common.h and update the following parameters for the device to establish connection w/ the access-point

   #define SSID_NAME       "<ap_name>"
   #define SEC_TYPE        <security-type>
   #define PASSKEY         ""

• Edit main.c and update the following parameters of the remote server

   #define IP_ADDR         0xc0a80164

• Build and launch the application
• Open an Iperf TCP server listening on port PORT_NUM on Windows-PC

   Iperf -s -p <PORT_NUM> -i 1

• The device will connect to Iperf server and send some packets
• The application also starts a TCP server on PORT_NUM
• Open an Iperf client on Windows, connect to CC3100 on PORT_NUM
• The Iperf version used in testing was: iperf-2.0.9-win64 (running on windows 10)

   Iperf -c <DEST_IP_ADDR> -p <PORT_NUM> -i 1

• The device receives the packets sent by the Iperf client and closes the socket.
• See the self explanatory logs on the terminal-program's console. On success, below message will be displayed on the terminal
