WINC3400 Simple Roaming UDP Client Example - SAMD21 XPlained Pro Documentation

Introduction

This example demonstrates the use of the WINC3400 with the SAMD21 Xplained Pro board to test continuous data transmission between UDP client and UDP server in roaming.
It uses the following hardware:

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

Main Files

• main.c : Initialize the WINC3400 and test UDP 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. On the computer, run the udp_server.py script to start server.
5. Start the application.
6. In the terminal window, the following text should appear:
