Introduction

This example demonstrates the use of the WINC3400 with the SAMD21 Xplained Pro board to send email using SMTP server.
It uses the following hardware:

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

Main Files

• main.c : Initialize the WINC3400 and send email.

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_SENDER_RFC                 "<sender@gmail.com>"
