Remote Control Design SDK (BLE, ZigBee)

Remote Control Design

In a nutshell

In this case study, we will explore the project undertaken by the engineering team at needCode to develop a Software Development Kit (SDK) for pilots. The goal was to enable customers to download a pre-built SDK, allowing them to design their own pilot with ease. The primary focus of the project was on the hardware aspect, particularly the creation of a chip that supports both Bluetooth and ZigBee technologies. The key objective was to achieve BLE pairing and button testing functionality for the pilots.

Project overview

Project Duration:

07.2022- 11.2022

Team Setup:

2 x Embedded Software Engineers


BLE, ZigBee, C, python

Client Requirements

The client required a comprehensive SDK that would facilitate the creation of custom pilots. The SDK needed to include a chip for remote control, supporting Bluetooth and ZigBee technologies. Additionally, an API needed to be developed, seamlessly integrating the hardware components, and a demonstration application was to be created to showcase the SDK’s capabilities.

Project Scope

The project’s scope was created to achieve the following objectives:

  • Developing a versatile chip that can serve as the core of the remote control, supporting both Bluetooth and ZigBee protocols.
  • Designing and implementing an API to efficiently combine the hardware components and provide a user-friendly interface for the customers.
  • Creating a demonstration application that showcases the functionality of the SDK, particularly focusing on BLE pairing and button testing.
  • Providing the client with an evaluation board, pre-equipped with the necessary hardware, to enable the development of custom applications for remote control across various devices such as TV and projectors.


To meet the client’s requirements and achieve the project’s objectives, the needCode engineering team adopted the following approach:

  • Conducted a thorough analysis of the client’s needs and expectations for the SDK.
  • Researched and selected suitable hardware components for the chip, ensuring compatibility with both Bluetooth and ZigBee protocols.
  • Collaborated closely with hardware and software engineers to integrate the selected components effectively.
  • Implemented robust BLE pairing and button testing functionalities through meticulous software development.
  • Designed an intuitive and well-documented API to simplify the process of custom pilot design for the customers.
  • Rigorously tested the SDK, evaluating its performance, reliability, and compatibility with various devices.
  • Provided the client with an evaluation board containing the SDK and necessary hardware for seamless application development.

Challenges and Goals

The project encountered several challenges throughout its execution, including:

  • Ensuring seamless integration of Bluetooth and ZigBee technologies within a single chip.
  • Developing a reliable and secure BLE pairing mechanism for enhanced user experience.
  • Addressing compatibility issues with different devices and manufacturers in the demonstration application.
  • Balancing the need for a flexible API with a user-friendly interface for customers with varying levels of technical expertise.

Results and Achievements

The needCode engineering team successfully delivered the SDK for pilots, meeting the client’s expectations and project objectives. Key results and achievements include:

  • The development of a powerful and versatile chip supporting both Bluetooth and ZigBee technologies, functioning as the core of the remote control.
  • Creation of a well-documented API that allows customers to easily design their custom pilots, with ample hardware support.
  • The demonstration application showcased the SDK’s BLE pairing and button testing capabilities effectively.
  • The evaluation board provided to the client facilitated the development of diverse remote control applications for various devices.


The successful development of the SDK for pilots highlighted needCode’s expertise in hardware and software integration. By delivering a powerful chip with Bluetooth and ZigBee support, an intuitive API, and a functional demonstration application, needCode empowered its client to design and create custom remote controls efficiently.

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.
