How does the evaluation version work, and what is included?

 

The free evaluation license allows you to test the full functional stack on your Silicon Labs hardware for a limited period. You receive:

  • A precompiled evaluation stack
  • Hardware‑specific drivers
  • Example applications and basic documentation
  • Sufficient functionality to validate performance, protocol behavior, and integration effort

Some limitations apply (e.g., reduced payload handling or restricted production use), but everything you need for real testing is included. Vistit the Evaluation license page for a full overview.

 

With a commercial license, you gain access to extended support and long‑term maintenance. With our different license options, you get support options included or you can buy support packages according to your needs.

  • Updates, patches, and protocol revisions
  • Technical assistance
  • Customization or porting services
  • Guidance during certification or field deployment
  • Guaranteed long‑term availability of the stack

This ensures your product stays secure, compatible, and future‑proof throughout its lifecycle.


You can start testing almost immediately. Once you request your free evaluation, you’ll receive a precompiled stack package tailored to your Silicon Labs hardware — including drivers, example applications, and setup instructions. Simply download the package, flash it onto your development board, and you can begin validating functionality within minutes.

If needed, our documentation and example projects help you get your first communication tests running quickly and smoothly.

 
By combining your Silicon Labs hardware with a STACKFORCE protocol stack, you benefit from a solution that is performance‑tuned, standards‑compliant, and optimized for industrial IoT environments. Our stacks are engineered for low‑power wireless communication, robust networking, and efficient integration — making them an ideal match for Silicon Labs’ sub‑GHz and multi‑protocol SoCs.
