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_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:

   *    -- SSL example --
   *    -- SAMXXX_XPLAINED_PRO --
   *    -- Compiled: xxx xx xxxx xx:xx:xx --
   *    wifi_cb: M2M_WIFI_RESP_CON_STATE_CHANGED: CONNECTED
   *    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.)
