Features Supported in Simplicity SDK for Zephyr#
SoCs#
Support for Silicon Labs SoCs is added incrementally. See Software Quality Levels for details about support level for Series 2 and SiWx91x SoCs.
Boards#
See the
Silicon Labs board definitions in
the Zephyr upstream documentation. To build for a specific board, pass the board name using the
-b argument in the west build command.
You can use the Zephyr Supported Boards and Shields page to search for supported boards.
Wireless Protocols#
Series 2 devices fully support Bluetooth Low Energy (BLE) and provide Beta support for OpenThread (802.15.4). SiWx917 devices support BLE and Wi-Fi. Proprietary wireless protocols can make use of Alpha support for custom RAIL configurations on Series 2. Simplicity Studio must be used to generate radio configuration files that can be added to the Zephyr-based project.
The SiWG917 device supports both Wi-Fi and Bluetooth Low Energy (BLE) connectivity, enabling dual-protocol wireless operation. It is designed for ultra-low-power IoT applications that require seamless Wi-Fi networking alongside BLE-based control or provisioning.
To know more about the features supported for the wireless protocols, see Software Quality Levels.
Sample Applications#
Sample applications are available in the Zephyr upstream repository under Zephyr upstream Samples and Demos. These provide reference implementations for supported features and hardware.
In addition to the Zephyr upstream sample applications, Silicon Labs delivers dedicated sample applications in the downstream repository.
