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_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 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 --
   *    -- SAMD21_XPLAINED_PRO --
   *    -- Compiled: xxx xx xxxx xx:xx:xx --
   *    wifi_cb: M2M_WIFI_RESP_CON_STATE_CHANGED: CONNECTED
   *    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!
   *
