Frequently asked Questions

What is included in the STACKFORCE software package?

Our Protocol Stack package includes everything you need for integration:

  • Precompiled stack library
  • Hardware-specific drivers
  • Serial interface (UART, SPI, etc.)
  • Power management
  • Example applications for quick integration
  • Documentation

Is the source code open or encrypted? Can we make adjustments ourselves?

The Protocol Stack itself is delivered as object code and cannot be directly modified. The platform interface (including HAL and RF driver integration) is provided as source code. This allows you to:

  • Adapt the platform driver to your target hardware
  • Configure specific radio settings such as frequencies
  • Optimize driver behavior
  • Add your own components such as security and timers

For further adjustments to the stack itself, we are happy to support you with specific development services.

Does STACKFORCE provide support for product certification? If so, how?

STACKFORCE uses a multi-stage testing process to ensure high software quality.
