WINC3400 Iperf Example - SAMD21 XPlained Pro Documentation

Introduction

This example demonstrates the use of the WINC3400 with the SAMD21 Xplained Pro board to run Iperf server.
It uses the following hardware:

• the SAMD21 Xplained Pro.
• the WINC3400 on EXT1.

Main Files

• main.c : Initialize the WINC3400 and run Iperf server.

Usage

1. Configure the connection information in main.h.

   *    #define MAIN_WLAN_SSID                    "DEMO_AP"
   *    #define MAIN_WLAN_AUTH                    M2M_WIFI_SEC_WPA_PSK
   *    #define MAIN_WLAN_PSK                     "12345678"
   *    #define MAIN_WIFI_M2M_PRODUCT_NAME        "NMCTemp"
   *    #define MAIN_WIFI_M2M_SERVER_IP           0xFFFFFFFF // "255.255.255.255"
   *    #define MAIN_WIFI_M2M_SERVER_PORT         (6666)
   *    #define MAIN_WIFI_M2M_REPORT_INTERVAL     (1000)
   * 

2. Build the program and download it into the board.
3. On the computer, open and configure a terminal application as follows.

   *    Baud Rate : 115200
   *    Data : 8bit
   *    Parity bit : none
   *    Stop bit : 1bit
   *    Flow control : none
   * 

4. Start the application.
5. In the terminal window, the following text should appear:
