WINC1500 Connecting a MSCHAPV2 Enterprise Secured AP Example for SAM4S XPlained Pro Documentation

Introduction

This example demonstrates the use of the WINC1500 with the SAMxx Xplained Pro board to connect to a secured 802.1x enterprise network that supports MSCHAPV2 as phase 2 authentication.
The following Enterprise security methods are supported by this example.

 * - TTLSv0 with MSCHAPV2
* - PEAPv0 with MSCHAPV2
* - PEAPv1 with MSCHAPV2
* 

This example require following hardware:

• the SAMXXX Xplained Pro.
• the WINC1500 on EXT1.

Main Files

• main.c : Initialize the WINC1500 and connect to network that support enterprise security with MSCHAPV2 authentication protocol.

Usage

1. Assemble the devices and connect to USB debug cable from PC.
2. 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
   * 

3. Prepare an AP that supports enterprise security with any of the following security method.

• TTLSv0 with MSCHAPV2
• PEAPv0 with MSCHAPV2
• PEAPv1 with MSCHAPV2

1. You need to know following things before configuring RADIUS server settings in the AP. Ask your network administrator to get there information and configure it in the AP.

   *    User name
   *    Password
   *    Name of wireless network
   *    Root certificate file
   * 

2. Modify MAIN_WLAN_802_1X_USR_NAME, MAIN_WLAN_802_1X_PWD to the name and the password, respectively. Modify MAIN_WLAN_SSID to wireless network name

   *    #define MAIN_WLAN_SSID         "WINC1500_ENTERPRISE"
   *    #define MAIN_WLAN_802_1X_USR_NAME     "DEMO_USER"
   *    #define MAIN_WLAN_802_1X_PWD          "DemoPassword"
   * 

3. Build and run the application. If the device connected successfully, IP address which is assigned by DHCP will be displayed on the terminal program.
