WINC3400 SSL Connect Example - SAMD21 XPlained Pro Documentation

Introduction

This example demonstrates how to connect to a server via Secure Socket Layer (SSL) 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. Configure below code in the config main.h for AP information to be connected.
    * #define MAIN_WLAN_SSID "DEMO_AP"
    * #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:
    * -- SSL example --
    * -- SAMXXX_XPLAINED_PRO --
    * -- Compiled: xxx xx xxxx xx:xx:xx --
    * wifi_cb: M2M_WIFI_REQ_DHCP_CONF: IP is xxx.xxx.xxx.xxx
    * Host IP is xxx.xxx.xxx.xxx
    * Host Name is www.google.com
    * Successfully connected.
    *
Warning
* For using SSL, the root certificate must be installed.
* Download the root certificate using the root_certificate_downloader from the
* firmware update project available in the ASF. (Refer to WINC3400 Software User Guide.)
