1.6 First Steps: Out-of-Box Experience
An easy way to get started with the EVM is by using its preprogrammed out-of-box experience code. It
demonstrates some key features of the EVM.
1.6.1 Connecting to the Computer
Connect the LaunchPad development kit by connecting the included USB cable to a computer. A red
power LED should illuminate. For proper operation, the SimpleLink drivers and Service Pack from the
CC3235 Software Development Kit (SDK) are needed. The SDK is available at
http://www.ti.com/tool/simplelink-cc32xx-sdk.
1.6.2 Running the Out-of-Box Experience
The CC3235MODSF LaunchPad development kit's Out-of-Box Experience (OOBE) demonstrates and
highlights the following features:
• Easy connection to the CC3235MODSF LaunchPad:
– Using the SimpleLink
TM
Wi-Fi® Starter Pro application (available on iOS and Android™), users can
use Access Point (AP) provisioning or SmartConfig ™ provisioning for a fast CC3235MOD
connection.
– Configuring the device in AP mode gives users a direct connection to the CC3235MODSF
LaunchPad.
Once the device is provisioned and connected to an AP in station mode, the profile is stored on the
local file system so that any reset to the CC3235MODSF automatically connects it to the AP.
• Easy access to the CC3235MODSF through its internal web server, using either:
– The SimpleLink
TM
Wi-Fi® Starter Pro application
– Any browser; web pages stored on the serial flash are loaded on the browser, to provide ease of
use.
This feature demonstrates configuring and reading onboard sensors.
• Over-The-Air (OTA) updates that demonstrate an update of a full image. OTA service enables in-
system updates of the MCU application, CC3235 firmware releases (Service Pack) made available by
TI, and other vendor files. An update procedure executed in a full-system integrity fashion, such as
failure to upgrade any image components, results in rolling back to the previous valid version.
Visit the CC3235 LaunchPad Out-of-Box Experience Guide on SimpleLink Academy (see Section 6.3) for
more details.
1.7 Next Steps: Looking into the Provided Code
After the EVM features have been explored, the user can open an integrated development environment
and start editing the code examples from the SDK. See Section 6.2 for available IDEs and where to
download them. The Out-of-Box source code and more code examples are provided in the CC3235 SDK.
Code is licensed under BSD, and TI encourages reuse and modifications to fit specific needs.
