Introduction
This example demonstrates the use of the WINC3400 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 requires the following hardware:
- the SAMXXX Xplained Pro.
- the WINC3400 on EXT1.
Main Files
- main.c : Initialize the WINC3400 and connect to network that supports enterprise security with MSCHAPV2 authentication protocol.
Usage
- Assemble the devices and connect to USB debug cable from PC.
- On the computer, open and configure a terminal application as follows.
* Baud Rate : 115200
* Data : 8bit
* Parity bit : none
* Stop bit : 1bit
* Flow control : none
*
- Prepare an AP that supports enterprise security with any of the following security methods.
- TTLSv0 with MSCHAPV2
- PEAPv0 with MSCHAPV2
- PEAPv1 with MSCHAPV2
- You need to know the following parameters before configuring the RADIUS server settings in the AP. Ask your network administrator to get this information and configure it in WINC3400.
* User name
* Password
* Name of wireless network
* Root certificate file
*
- 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
- Build and run the application. If the device connected successfully, IP address which is assigned by DHCP will be displayed on the terminal program.
