Smart Home Gateway with BLE & ZigBee

Streamlining and Enhancing Customer’s Smart Home Gateway

In a nutshell

The task assigned to our engineer is to optimize and ensure the smooth operation of the latest version of the customer’s Smart Home Gateway. The Gateway plays a crucial role in managing Smart Home devices and relies on Thread protocol, ZigBee, Matter, and BLE technologies. It functions as a central device, configuring and controlling other devices through BLE, facilitating control of ZigBee or Matter based devices. The engineer’s primary responsibility is to address issues with the Gateway that cause disruption in the performance of associated devices, caused by main processor-related problems. Through rigorous testing, modifications, and enhancements, the engineer aims to ensure the Gateway’s proper functionality, improve its operation, and provide continued support to the customer.

Project overview

Project Duration:

01.2023- now

Team Setup:

1 x Embedded Software Engineers


BLE, ZigBee, Thread, Matter, C, python, Linux

Client Requirements

The client sought the development of an upgraded, high-quality gateway specifically tailored for Smart Home applications. This new version needed to function flawlessly and offer seamless configuration via Bluetooth Low Energy (BLE). Additionally, the gateway was required to effectively manage and control connected devices, such as those running on the ZigBee protocol.

Project Scope

  • Performance Optimization: Address issues stemming from a weak processor in the customer’s existing gateway.
  • Device Compatibility: Conduct tests to ensure that the gateway can support multiple new products without performance degradation.
  • Reliability Enhancement: Implement improvements to stabilize the performance of connected devices, eliminating queue-related issues that led to erratic behavior.
  • Testing: Rigorous testing to validate that the optimized gateway meets all performance and reliability criteria.


To achieve the project objectives, the engineer follows a systematic approach:

  • Conducts a thorough analysis of the customer’s Gateway to identify and understand the root causes of the scattered device performance.
  • Addresses problems related to the processor that lead to erratic behavior of connected devices.
  • Performs extensive testing and diagnostics to identify potential areas of improvement.
  • Implements necessary modifications and enhancements to streamline the Gateway’s performance and stability.
  • Focuses on supporting the customer throughout the optimization process, ensuring their requirements are met.

Results and Achievements

By employing the above approach, the engineer achieves the following results:

  • Successfully streamlines the Smart Home Gateway, resolving issues that caused disruption in connected device operations.
  • Improves the Gateway’s overall functionality and performance, leading to a more reliable and efficient Smart Home ecosystem.
  • Ensures seamless compatibility and control of ZigBee-based devices through BLE configuration.
  • Provides valuable support to the customer, ensuring their satisfaction and continued use of the enhanced Gateway.


Our engineer’s dedication and expertise in optimizing the Smart Home Gateway with Thread, ZigBee, Matter, and BLE technologies have resulted in a highly efficient and stable system. By addressing processor-related issues, the engineer has significantly improved the performance of connected devices and enabled smooth control over ZigBee-based devices through BLE configuration. The successful streamlining of the Gateway showcases the engineer’s commitment to delivering top-notch solutions and fostering a strong partnership with the customer.

Maintenance (Post-Release Support)

When your product is successfully launched and available on the market we provide ongoing support and maintenance services to ensure your product remains competitive and reliable. This includes prompt resolution of any reported issues through bug fixes and updates.

We continuously enhance product features based on user feedback and market insights, optimizing performance and user experience.

Our team monitors product performance metrics to identify areas for improvement and proactively addresses potential issues. This phase aims to sustain product competitiveness, ensure customer satisfaction, and support long-term success in the market.

Commercialization (From MVP to Product

Our software team focuses on completing the full product feature range, enhancing the user interface and experience, and handling all corner cases. We prepare product software across the whole lifecycle by providing all necessary procedures, such as manufacturing support and firmware upgrade.

We also finalize the product's hardware design to ensure robustness, scalability and cost-effectiveness.

This includes rigorous testing procedures to validate product performance, reliability, and security. We manage all necessary certifications and regulatory compliance requirements to ensure the product meets industry standards and legal obligations.

By the end of this phase, your product is fully prepared for mass production and commercial deployment, with all documentation and certifications in place.

Prototyping (From POC to MVP)

Our development team focuses on implementing core product features and use cases to create a functional Minimum Viable Product (MVP). We advance to refining the hardware design, moving from initial concepts to detailed PCB design allowing us to assemble first prototypes. Updated documentation from the Design phase ensures alignment with current project status. A basic test framework is established to conduct preliminary validation tests.

This prepares the product for real-world demonstrations to stakeholders, customers, and potential investors.

This phase is critical for validating market readiness and functionality before proceeding to full-scale production.

Design (From Idea to POC)

We meticulously select the optimal technology stack and hardware components based on your smart product idea with detailed use cases and feature requirements (Market Requirements Document / Business Requirements Document). Our team conducts thorough assessments of costs, performance metrics, power consumption, and resource requirements.

Deliverables include a comprehensive Product Requirements Document (PRD), detailed Software Architecture plans, an Initial Test Plan outlining validation strategies, Regulatory Compliance Analysis to ensure adherence to relevant standards, and a Proof of Concept (POC) prototype implemented on breakout boards.

This phase aims to validate the technical feasibility of your concept and establish a solid foundation for further development.

If you lack a validated idea and MRD/BRD, consider utilizing our IoT Strategic Roadmap service to gain insights into target markets, user needs, and desired functionality. Having a structured plan in the form of an IoT Strategic Roadmap before development begins is crucial to mitigate complications in subsequent product development phases.
