SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides teams in selecting the most suitable architecture for Nordic NCS projects, helping to avoid over- or under-engineering by comparing simple multi-threaded and SMF+zbus modular designs.

Core Features & Use Cases

  • Clear criteria for choosing between Simple Multi-Threaded (1-3 threads, quick prototypes) and SMF+zbus Modular (4+ modules, complex state machines).
  • Example scenarios: asset-tracker style applications, sensor hubs, modular gateways requiring scalable communication.
  • Migration guidance: how to transition from a basic multi-threaded approach to a modular SMF+zbus architecture.

Quick Start

Review the architecture patterns guide and select the pattern most suited to your project; then apply the recommended template or module layout to begin structuring your project for scalable development.

FAQPage Schema
How do I choose between simple multi-threaded and SMF+zbus modular architecture for Nordic NCS projects?▼

Choose simple multi-threaded architecture for quick prototypes with 1-3 threads, while SMF+zbus modular architecture suits large systems with 4+ modules requiring strict maintainability and structured state machines.

What is the zbus framework used for in NCS modular design?▼

Zbus provides decoupled communication between modules in Nordic NCS projects, enabling clear module boundaries and scalable communication for complex applications like modular gateways and sensor hubs.

How do I migrate a Nordic NCS project from multi-threaded to SMF state machine architecture?▼

Migration from a basic multi-threaded approach to a modular SMF+zbus architecture is supported through structured guidance, transitioning your project to decoupled communication and clear module boundaries.

When do I need state machines for Nordic NCS development?▼

State machines are needed when your Nordic NCS project scales to 4+ modules with complex logic, requiring structured state management (SMF) and strict maintainability beyond simple prototypes.

Does the SMF and zbus architecture pattern work for asset-tracker style applications?▼

Yes, the SMF+zbus modular architecture applies to asset-tracker style applications, sensor hubs, and modular gateways that require scalable communication and complex state machine management.

What are the limitations of simple multi-threaded design in NCS projects?▼

Simple multi-threaded design limits scalability and maintainability in NCS projects with 4+ modules, lacking the decoupled communication and structured state machines provided by the SMF+zbus modular approach.
