The Simplicity SDK combines Silicon Labs wireless software development kits (SDKs) and Platform into a single, integrated package. The Simplicity SDK is your primary tool for developing in the Silicon Labs IoT Software ecosystem. All of Silicon Labs' stacks are written in-house to provide a seamless experience from silicon to tools, allowing you to unlock powerful features with ease, including:
- Abstraction of complex requirements like multiprotocol and pre-certification
- Industry-leading ability to support a large number of nodes
- Ultra-low power consumption
- Strong network reliability
Silicon Labs also helps future-proof your devices with over-the-air software and security updates, helping to minimize maintenance cost and improve your end user product experience!

The Simplicity SDK is covered by one of several different licenses. The default license is the Master Software License Agreement (MSLA), which applies unless otherwise noted. Refer to License.txt for full details.
An archive of all documents associated with the latest release of Simplicity SDK can be found in Releases. Documentation for some of the protocol SDKs and software components is available on https://docs.silabs.com.
The recommended method to get started with the Simplicity SDK is to first install Simplicity Studio 5, which will setup your development environment and walk you through the installation of Simplicity SDK. Alternatively, Simplicity SDK and other required tools may be installed manually.
Simplicity Studio 5 includes everything needed for IoT product development with Silicon Labs devices, including:
- Detection and recognition of evaluation and development kits,
- Resource navigator with kit and device-specific content,
- Software project generator for multiple IDEs and GNU Make targets,
- Software and hardware configuration tools,
- Eclipse CDT-based IDE,
- GNU toolchain,
- Advanced network analysis tools,
- Code-correlated energy profiling,
- And a variety of other tools.
Start by downloading the Simplicity Studio package for your operating system from https://www.silabs.com/simplicity. Step-by-step installation instructions are provided in the online Simplicity Studio 5 User’s Guide.
A Simplicity SDK development environment may also be installed and set up manually.
Simplicity SDK releases are packaged as an archive that may be downloaded from the Releases page on GitHub. You may also clone this repo using a git client. Note that an installation of git lfs is also required. If you are installing git lfs only to use with the 12.2.rel1, you do not need to specify file types.
This release of Simplicity SDK supports the Arm Embedded Toolchain version 12.2.Rel1 and IAR Embedded Workbench version 9.40.1. One of these toolchains must be installed.
- GNU Arm Embedded Toolchain - Download and install v12.2.Rel1 for your host operating system.
- IAR Embedded Workbench for Arm - Only the latest version is available in Downloads; for older versions you must log-in to your "My Pages".
Simplicity SDK contains software that follows the SLC specification. Software is grouped into components (defined by .slcc files) that may provide features and/or require features provided by other components. Example projects (.slcp) describe a single software application (usually made up of multiple components plus application code) that can be used to generate an IDE project.
Simplicity Studio 5 includes a pre-integrated version of SLC tooling. The SLC-CLI tool provides a command-line alternative that, among other things, will resolve project and component dependencies and generate a project for a specified embedded target and build system (for example, IAR Embedded Workbench or GNU tools via a Makefile).
See the SLC specification for details about SLC. For information on installing and using the SLC-CLI, see UG520: Software Project Generation and Configuration with SLC-CLI.
