SWRU461B–February 2017–Revised June 2018

Execute your First Application

The SDK supports the following device variants:
• CC3220 – Base variant
• CC3220S – CC3220 + MCU security
• CC3220SF – CC3220S + internal flash
The SDK is packed with precompiled binaries for several networking and peripheral examples. By default, the sample applications are built for the CC3220SF variant. The user can easily compile the same applications for the other variants just by selecting them in the project properties. See Section 2.1 to compile the sample application for the required device variant.
This document uses Network Terminal as the reference application. The Network Terminal application provides a CLI (command line interface over UART connection) that lets users activate basic SimpleLink operations such as triggering a WLAN scan, connecting to a local access point (or setting an access point or Wi-Fi-Direct connection), and performing networking services such as PING, MDNS, or data transfer over TCP/UDP sockets. The application also enables configuration of Wake-On-WLAN filters and scan policy and lets the user put the device in a transceiver mode for testing TX and RX operations.
This example uses a real-time operating system (TI-RTOS or FreeRTOS). The following instructions will use the CC3220SF device and TI-RTOS, but can be easily changed to other combination, by:
• Selecting the CC3220S device-specific directory (CC3220S_LAUNCHXL instead of CC3220SF_LAUNCHXL)
or
• Selecting sample project for FreeRTOS (for example, network_terminal_CC3220SF_LAUNCHXL_freertos_ccs instead of network_terminal_CC3220SF_LAUNCHXL_tirtos_ccs)
