How To Connect Wi-Fi Without User Interface: Wi-Fi Easy Connect Implementation in RDK-B

Introduction

In the modern scenario, the number of Wi-Fi-enabled devices continue to grow especially in smart homes and industrial IoT environments. Traditional methods like Wi-Fi Protected Setup (WPS) are outdated, less secure, and impractical for headless devices that lack screens or input interfaces. We need to think of ways and means to provide a secure onboarding of these devices. One effective way to connect devices to Wi-Fi without user interface is through Wi-Fi Easy Connect™, powered by the Device Provisioning Protocol (DPP). This is a method that removes the need for manually entering password allowing devices to be safely added to a network using QR codes.

In this blog, we seek to explore how to connect Wi-Fi without user interface using Wi-Fi Easy Connect in RDK-B, which is a popular broadband platform, equipped to simplify secure wireless onboarding.

Wi-Fi Easy Connect: How to Connect Wi-Fi Without User-Interface Using Secure Device Provisioning

Wi-Fi Easy Connect™ is a secure provisioning protocol defined by the Wi-Fi Alliance. Wi-Fi Easy connect simplifies the process of onboarding new devices into a Wi-Fi network, especially those lacking user interfaces (e.g., IoT sensors or home appliances).

At the core of Wi-Fi Easy Connect is DPP (Device Provisioning Protocol), which uses public- key cryptography instead of shared passwords. The process typically involves a Configurator and an Enrollee (e.g., a Wi-Fi device to be onboarded). Secure provisioning is initiated using mechanisms such as:

• QR code scanning
• NFC tap
• Out-of-band Wi-Fi negotiation

This approach enables secure device provisioning with minimal user intervention while maintaining strong security. Here, we are specifically focusing on onboarding a device to Wi-Fi access point via QR code scanned by the Configurator—highlighting exactly how to connect Wi-Fi without user interface securely.

RDK-B (Reference Design Kit – Broadband) is an open-source platform that powers broadband gateways, routers, and access points. The scalable architecture and standardized interfaces enable rapid development and the integration of new features.

In order to address the onboarding challenges posed by headless and IoT devices, we at ThinkPalm, bring forth the integration of Wi-Fi Easy Connect in RDK-B as a strategic move. RDK-B’s flexible TR-181 data model enables seamless integration of DPP (Device Provisioning Protocol), allowing gateways to operate as secure Configurators. This integration adds DPP parameters to the data model, facilitating effective tracking, device management, and device monitoring through existing management frameworks.

By leveraging Wi-Fi Easy Connect within the RDK-B framework, operators gain a powerful solution for managing modern home and enterprise networks. With the growing number of IoT and smart devices, onboarding devices without user interface has become essential. Wi-Fi Easy Connect not only supports secure device provisioning but also makes the process scalable.

With the help of TR-181, RDK-B provides centralized device visibility, real-time monitoring, and configurable network behavior. This is a combination that delivers an enhanced user experience, supports faster deployments and makes way for easier troubleshooting. Wi-Fi Easy Connect and RDK-B together, render a scalable, secure, and future-ready Wi-Fi onboarding solution.

The end-user is provided with:

• Seamless onboarding of smart devices such as bulbs, cameras, and speakers without screen.
• Hassle-free device connectivity with Wi-Fi access point during gateway configuration changes.

One can gain access to a convenient and secure approach, and all this is feasible without user interface.

By enabling Wi-Fi Easy Connect in RDK-B, service providers can offer:

• Secure, password-less provisioning.
• Reduced need for manual configuration.
• Improved user experience with smart device connectivity.

Wi-Fi easy connect allows service providers to offer future-ready Wi-Fi connectivity without entering the password, without compromising security elements.

Prerequisites for Integrating Wi-Fi Easy Connect in RDK-B for Seamless Wi-Fi Access 

Before enabling Wi-Fi Easy Connect in RDK-B, the following prerequisites must be met for executing secure device provisioning:

• A Wi-Fi router or gateway device using RDK-B software– This is the main device with modified RDK-B image that supports Wi-Fi Easy connect.
• A smartphone or companion app is used to scan a QR code and connect new devices to Wi-Fi.
• A smart device that supports Wi-Fi Easy Connect (DPP) – For example, an IoT gadget like a smart bulb, plug, or sensor that can be securely onboarded.

How to enable Wi-Fi Easy Connect in RDK-B:

Listed below are the steps that enable operators to complete secure device provisioning via Wi-Fi Easy Connect in RDK-B:

1. Flash ThinkPalm’s Wi-Fi Easy Connect enabled RDK-B image onto a gateway
2. Scan QR Code from Enrolee Device
   A QR code generated by the device to be onboarded (Enrolee) is scanned using a smartphone app capable of securely communicating with the gateway.
3. Trigger DPP Initialization
   The scanned information is used to start the provisioning handshake between the Gateway and the Enrolee devices.
4. Mutual Authentication
   Public key-based cryptographic exchange validates both Gateway and Enrollee securely, ensuring only authorized devices are added.
5. Exchanging Network Credentials
   The Gateway securely transfers the credentials to the Enrollee device through Wi-Fi frames.
6. Persist Configuration
   The gateway saves connection data to ensure the onboarded device reconnects automatically after reboots.

At ThinkPalm, we ensure that each step is aligned with RDK-B’s modular design and data model flexibility to enable smooth deployment.

Understanding the DPP (Device Provisioning Protocol)

DPP is a public key-based authentication and provisioning protocol, and it consists of the following phases:

• Bootstrap: Enrollee’s identity is shared using a QR code or another method.
• Authentication: Mutual validation using public/private key exchange.
• Configuration: The Wi-Fi configuration is sent to the Enrollee by the Gateway
• Completion: Secure onboarding is completed and confirmed on both ends.

These are central to how we connect to Wi-Fi without user interface, ensuring that only authorized devices are onboarded, and Wi-Fi credentials are never exposed.

Testing Wi-Fi Easy Connect Functionality

Testing involves validating the end-to-end flow:

• Confirm DPP parameters are correctly configured in the TR-181 model.
• Scan the QR code and observe system behaviour.
• Ensure successful authentication and verify that credentials are saved.
• Reboot the system and confirm persistence.
• Verify Wi-Fi connectivity on the onboarded device.

At ThinkPalm, we test real-world conditions and edge cases to ensure robust implementation of Wi-Fi Easy Connect in RDK-B.
