CC3100 UDP Socket Application

Overview and application details

This is a sample application demonstrating how to open and use a standard UDP 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 UDP server listening on port PORT_NUM on Windows-PC (the Iperf version used in testing was: iperf-2.0.9-win64 running on windows 10)

       Iperf -s -p <PORT_NUM> -i 1 -u

• The application will connect to Iperf server and send few dummy packets
• The application also starts a UDP server on PORT_NUM
• Open an Iperf client on Windows and connect 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 -u

• 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

Limitations/Known Issues

• The Iperf client command may need to be run more than once
