EFR32™ Flex Gecko 2.4 GHz and 169 MHz Proprietary Wireless Starter Kit

SLWSTK6065B

The Flex Gecko Wireless SoC Starter Kit is enabled through the Silicon Labs Flex SDK which contains the Connect Stack and the Radio Abstraction Interface Layer (RAIL) to simplify proprietary wireless protocol development. Extensive documentation and sample applications, including the popular range test, as well as functionality for lab evaluation, wake-on-radio, bi-directional packet transmission and reception are also provided as source code within the Flex SDK sample applications. Using the Simplicity Studio suite of tools, developers can take advantage of graphical user interface to quickly generate wireless applications, perform energy profiling and various system optimizations. Connect Stack is an IEEE 802.15.4 based networking stack designed for creating easily customizable broad-based proprietary wireless applications and supports both sub-GHz and 2.4 GHz frequency bands.
