Objective
This lab demonstrates the ease of use of the WINC1500 module to enable wireless connectivity. We will connect the host MCU to a secure Acces Point (AP) using the WINC1500 module.

Procedure
1
Create a New Example Project
Click on the Example Project button.
2
Search for WINC1500 Projects
In the search box type in WINC1500 and then expand the example list tree to browse through the example projects.
3
Select AP Example
Select the WINC1500 AP Scan Example. In this lab, we are using the SAMD21 Xplained Pro Board which means we have to select the 'WINC1500 AP Scan Example - SAMD21 Xplained Pro' option.
Click OK.
4
License Agreement
Accept the License Agreement and click Finish.
5
Build Project
Go to the 'Build' menu and select 'Build Solution'.
6
Select the Debugger/Programmer
Click on None on (top right side of the screen) and under Selected programmer/debugger, select 'EDBG MSD'.
7
Open a Terminal Window
Use the following serial port settings:
8
Program the Device
Press the Start Without Debugging button.
When an update for the WINC module is provided, it usually combines the Wi-Fi software API for the host MCU and a binary firmware for the WINC module. To ensure the compatibility between the Wi-Fi software API on the host MCU and the WINC module, a major/minor/patch version number is used and verified at the Wi-Fi driver init. When a version mismatch is detected at startup, the Wi-Fi driver initialization fails and the m2m_wifi_init() function returns an error code:
If you see the Mismatch Firmware Version error, you will need to update the firmware on your module by following the instructions on the "WINC1500 Firmware Update" page.
9
List of available Access Points (APs)
After the project has been written to the device, you will see the list of available access points on the terminal program.
10
SSID and Password
If you would like the WINC1500 to connect to a specific network, go to line 49 of main.h and change the SSID to the name of the network you'd like to join. Also on line 51, change 12345678 to the correct password used to join the network.
11
Program the Device
Press the Start Without Debugging button.
12
Connection Successful
In the terminal window, you'll see that the connection was successful.
Results
In this example, the Access Points are scanned and if a scanned AP matches the pre-configured AP in the application, the WINC1500 connects to it.
