Our newest embedded software platform, the Simplicity Software Development Kit (SDK), is designed specifically for our Series 2 and upcoming Series 3 devices. The Simplicity SDK is a significant advancement in IoT development, providing our customers with a cohesive development environment for wireless innovation. It enables wireless developers to utilize advanced features and capabilities with the most recent Silicon Labs IoT devices.
Meanwhile, our Gecko Software Development Kit (GSDK) will continue to be available for users of our Series 0 and Series 1 devices.
The Gecko SDK will continue to support all Series 0 and 1 devices with no change to the long-term support, maintenance, quality, and responsiveness provided under our software policy.The new SDK will branch from Gecko SDK and begin to offer new features that help developers take advantage of the advanced capabilities of our Series 2 and 3 products.
This decision aligns with customer feedback, reflecting our commitment to elevate quality, ensure stability, and enhance performance for an exceptional user experience across our software SDKs.
Which SDK Do I Need?
Separate SDKs for Series 0 & 1 and Series 2 & 3 Starting in Q2 2024.

Z-Wave and Z-Wave Long Range 800 Version 7.24.0.0
- Key Features
- The Z-Wave stack and associated binary resources are compiled with the Link Time Optimization (LTO) option enabled
- S2v2 draft implementation supports the Supervision Command Class and is aligned with the latest proposed specification
- ZPAL watchdog refactoring
- Z-Wave Power Manager refactoring
- API Changes
- The watchdog is not enabled by stack anymore. It is the application's duty to enable it using zpal_watchdog_init and zpal_enable_watchdog. Application tasks should not block other tasks for more than 4 seconds
- Introduction of zw_power_manager_init(), zw_power_manager_lock(), zw_power_manager_relock(), zw_power_manager_lock_cancel(), to replace and wrap the ZPAL power manager functions. An application must use the zw_power_manager APIs rather than their ZPAL counterparts
- Aligned User Credential Command Class according to the 2025A specification changes by modifying the API of the CC_UserCredential_move_credential_and_report() function. The specification for the "User Credential Association Set" and "User Credential Association Report" commands was updated: the option to move a credential to a different slot was removed. Moving a credential to a different slot is still possible via the CLI; however, the lifeline group can no longer be notified about a credential slot change
- App initialization is changed. main.c has been removed from the sample applications and is now generated automatically by the System Setup (sl_main) platform component instead of the sl_system. For more information, refer to the documentation for System Initialization and Action Processing
- The Debug Print component was replaced by the ZPAL Log API, which allows filtering log messages by source component and log level
- Bug Fixes
- Below is a list of important bugs fixed in the release. For a complete list, see release notes link
- Fixed an issue where the radio layer would stop receiving packet until the next TX radio event (1409388)
- Fixed a rare occurrence where a null pointer led to a soft reset in the ZAF event queue (1425779)
