WINC3400 Simple TCP Client Example - SAMD21 XPlained Pro Documentation

Introduction

This example demonstrates the use of the WINC3400 with the SAMD21 Xplained Pro board to test TCP client.
It uses the following hardware:

  • the SAMD21 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 TCP client example --
    * -- Compiled: xxx xx xxxx xx:xx:xx --
    * m2m_wifi_state: M2M_WIFI_REQ_DHCP_CONF: IP is xxx.xxx.xxx.xxx
    * -# On the computer, run the tcp_server.py script to start server.
    * -# In the terminal window, the following text should appear:
    * socket_cb: connect success!
    * socket_cb: send success!
    * socket_cb: recv success!
    * TCP Client Test Complete!
    *
