WINC3400 ALPN Connect Example - SAMD21 XPlained Pro Documentation

Introduction

This example demonstrates how to connect to a server via Application Layer Protocol Negotiation (ALPN) using the WINC3400 Wi-Fi module.
It uses the following hardware:

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

Main Files

• main.c : Initialize the WINC3400 Wi-Fi module and connect to a server using SSL.

Usage

1. The connection parameters can be configured in main.h.

   *    #define MAIN_WLAN_SSID                  "DEMO_AP"
   *    #define MAIN_WLAN_AUTH                  M2M_WIFI_SEC_WPA_PSK
   *    #define MAIN_WLAN_PSK                   "12345678"
   * 

2. Build the program and download it into the board.
3. On the computer, open and configure a terminal application as following.

   *    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:
