WINC3400 Simple Roaming TCP Client Example - SAME70 XPlained Pro Documentation

Introduction

This example demonstrates the use of the WINC3400 with the SAM Xplained Pro board to test continuous data transmission between TCP client and TCP server in roaming.
It uses the following hardware:

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

Main Files

  • main.c : Initialize the WINC3400 and test TCP client.

Usage

  1. Configure below code in the main.h for AP information to be connected.
    * #define MAIN_WLAN_SSID "DEMO_AP"
    * #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)
    *
  2. Build the program and download it into the board.
  3. On the computer, open and configure a terminal application as the 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:
    * -- WINC3400 Simple Roaming TCP client example --
    * -- SAMXXX_XPLAINED_PRO --
