CC3100 Provisioning Smart Config

Overview and application details

This is a sample application demonstrating how to provision CC3100 to a Wi-Fi network using SmartConfig.

Warning: SmartConfig™ cannot provision embedded systems in all circumstances. Therefore, products should not go to production implementing only SmartConfig™. Access Point mode or WPS should be implemented and be used as a backup in case SmartConfig™ fails to provision the system.

What is SmartConfig? A first step in utilizing CC31xx in a Wi-Fi enabled application is to configure CC3100 to a user's Wi-Fi network. This requires information on the AP, or SSID name, and the security passcode when WEP/WPA/WPA2 is enabled. Considering that embedded Wi-Fi applications will generally lack user interfaces such as keypads or touchscreens, this process can be complex without the use of advanced I/O.

To create a great user experience, TI has created SmartConfig technology - a one-step and one-time process to connect a CC31xx-enabled device to the home wireless network. This greatly stands apart from other Wi-Fi suppliers who require multiple steps to configure a device onto the network.

SmartConfig leverages the standard mechanisms present in Wi-Fi to configure a CC31xx's association information on the fly, regardless of whether the user-interface is available. In this process a Wi-Fi enabled device such as a smartphone, tablet or a laptop is used to send the association information to the CC31xx.

Addtionally, SmartConfig does not depend on the host microcontroller's I/O capabilities, thereby usable by deeply embedded applications. It can be used to associate multiple devices to the same AP simultaneously. The Configuration process is secured with AES-128 encryption, and the SSID and KEY length are supported up to 32 bytes.

And furthermore, the device used to configure (smartphone, tablet, or PC) stays connected to the user's home network during the configuration process (as opposed to other methods that require disconnection).

Usage

• Connect the board to a Windows-PC and configure the terminal-program for seeing the logs - CC31xx & CC32xx Terminal Setting has detailed instructions for configuring the terminal-program
• Build and run the application.

• See the logs on the terminal-program's console. On success, below message will be displayed on the terminal

Limitations/Known Issues

• To access the website the user is prompted for a username + password. These are both: "admin"
