      • Deprecation of SL Thread in favor of OpenThread

        afpeters | 08/213/2019 | 09:01 PM

        Silicon Labs took the decision to deprecate its proprietary implementation of Thread and instead be a major contributor to the more popular OpenThread implementation.


        The announcement was made as part of the release notes for Silicon Labs Thread (SL-Thread) SDK  v2.10.1.0 which can be found here:


        The notice indicates that the inclusion of the SL-Thread implementation will be removed from the Simplicity Studio release scheduled in December 2019.


        The notice re-iterates that Silicon Labs has a continued focus on its Thread strategy and is committed to continuing as a leading-edge Thread supplier. Support for Thread will continue within the Silicon Labs software and hardware tools but the stack availability itself will be distributed through the commonly accessible OpenThread GitHub repository.


        More information on the OpenThread implementation can be found at:

      • Scheduled Maintenance, June 11th 2019

        Nari Shin | 05/148/2019 | 11:45 AM

        What’s happening?

        We will upgrade our community site on June 11th, 2019 to release bug fixes and performance improvements. As part of the upgrade, we will migrate our community badge images to a new location. During the maintenance, you may see some odd behaviors. 


        What are the odd behaviors?

        Profile page:

        You may see the most recent earned badge under your user name twice during the migration process. In addition, badges listed under the ‘Badges’ tab may not be displayed during the migration process.

        Forum and KB page:

        Earned badges may not be displayed during the badge migration process. You may see a few “Unknown” posts during the migration window. 


        Expected Maintenance Time:

        Tuesday, June 11th, 2019, ~11:00 AM CT. The migration may take 2-6 hours.


        What action do I need to take:

        Community members don’t need to take any action. Badging and the "Unknown" posts should appear normal after the migration is complete.


        Please contact us at if you have any issues during the maintenance window.
