Unified Interface (RUI3)

A Unified, Open Source, and Simple Coding Experience

Develop, compile, distribute, and contribute to your own firmware with ease.

We Listened

Early RAK customers expressed the desire to develop their own firmware. As a response, we developed the RAKwireless Unified Interface (RUI3).

RUI was Born

We believe that customers should have the tools necessary to unlock the full potential of their hardware. RUI3 allows users to develop, compile, and distribute custom firmware across the entire suite of RAK products.

Faster Time to Market

We can help you accelerate product development efforts and shorten the time-to-market. Additionally, firmware developed using RUI3 can be distributed to end devices using WisToolBox, a software utility interface created by RAKwireless.

RUI3 is now

Open Source

In alignment with our commitment to fostering innovation and community collaboration, we are thrilled to announce that RUI3 is now open source.

This decision empowers developers worldwide to learn from, adapt, and contribute to RUI3, enriching this powerful tool's capabilities. By opening RUI3 to the global developer community, we aim to accelerate the pace of innovation, enhance its appeal, and together, create products that push the boundaries of what's possible with RUI3.

RUI3—An Open Source SDK Designed for IoT

Supported Hardware

RUI3 now supports a wide range of hardware, including:

Modules and Boards

Enhancing IoT Customization

Seamless Configuration, Integration, and Comprehensive Functionalities

WisToolBox Integration

Developers can use WisToolBox to configure boards by RUI3 or keep the same AT command as RUI3. This integration enables user-friendly configuration tools for custom products, adding value and convenience to the development process.

RUI3 Integrates with Popular IDEs

RUI3 integrates smoothly with Visual Studio Code, Visual Studio IDE, and Arduino IDEs. Within these development environments, you can write customized firmware, compile, and upload directly through the IDE.

Comprehensive API Support

RUI3 provides a comprehensive set of APIs, covering a wide range of functionalities. It includes APIs for Arduino, System, LoRaWAN®, BLE, NFC, and One Wire Serial. These APIs are designed to offer maximum flexibility and ease of use for developers, allowing them to create customized IoT solutions with ease.

The RAK3172 module, powered by RUI3 firmware, offers an optimal low-power solution for IoT devices. With a sleep current of less than 2uA, it ensures extended battery life and cost-effectiveness for IoT developers.

Solution Provider with Own Hardware Product. RAK Makes it Very Easy to Join the IoT.

With RAK's LPWAN modules and WisBlock system, IoT adaptation becomes seamless. The intuitive RUI3 interface aids in effective network management, paving the way for rapid scaling.

How to Get Started with RAK11720 LoRa BLE Apollo3 Blue Module with Arduino IDE

Learn how to use the Arduino IDE with the RAK11720 Module, supported by the RUI3 firmware framework. This tutorial offers insight into LoRa P2P, LoRaWAN, and Bluetooth LE applications.

Portability Inspired by Arduino

Compiled RUI3 firmware can easily be deployed to different RAK hardware modules with little to no changes. The framework was inspired by Arduino, which means that experienced hardware developers can take advantage of powerful vendor-specific features while staying close to what they know.

A firmware development platform that spans across multiple hardware platforms

Customizable and Flexible

Modules from other IoT product manufacturers are usually interfaced to an external microcontroller (MCU). The interface between the module and the MCU is via fixed set AT commands.

On RUI3, users are allowed to create their own set of AT commands. This feature allows users to have flexibility in their IoT Applications. Common example of custom AT commands include:

Updating of uplink interval

Configuration of application related parameters

Creation of custom command for certain LoRaWAN® parameters

Built for the IoT of the Future;
Compatible with the IoT of Today

We built RUI3 with the future of IoT in mind. Firmware generated using RUI3 is exceptionally efficient in low-power environments, surpassing the default Arduino board support package (BSP). Optimizing for the lowest current usage was paramount for our R&D team.

Of course, RUI3 supports all established IoT protocols such as LoRAWAN, LoRA P2P, BLE, and LTE/NB-IoT. You can also implement your own proprietary IoT protocol using the framework. Many modules feature Bluetooth Low Energy (BLE) support. Our proprietary LoRaWAN over-the-air (OTA) protocol is used for wireless firmware upgrades.
