⚙️The Role of QA in Our Projects
At Stormotion, we are incredibly proud of our growth path and expertise in the dynamic areas of IoT, Mobility and Fitness. Over the years, we have gained invaluable experience working together with our clients to overcome challenges and provide solutions that provide seamless support to our clients, ensuring that their projects are completed on time and stand out in a competitive market.
In this article, we want to share with you our experience and ideas in creating projects in the field of IoT, Mobility and Fitness.
In this section, we will tell you about our achievements in developing an application for the Fitness industry. Let’s start!
One of our clients, a long-standing partner, recently acquired its French competitor, bestowing upon us the pivotal role of supporting their application and seamlessly integrating the new addition into their ecosystem.
Beyond the application itself, we faced the critical task of maintaining and advancing the middleware responsible for aggregating fitness data from diverse services: Apple Health, Garmin, Google Fit, and more. This middleware served as the lifeblood of their fitness solution, capturing essential metrics such as steps, cycling distances, and calories, propelling users toward their fitness goals.
The project presented a daunting challenge; it was written in Scala, a technology unfamiliar to our team, leaving us grappling with support issues. Furthermore, the previous development team had disbanded, leaving us with sporadic assistance from a lone developer.
Complicating matters further, time was of the essence as our client had inked a significant contract with a prominent French bank, demanding immediate restoration of the module's functionality.
In order to solve this problem, we decided to rewrite the entire module using our JS stack, thereby enabling future support and growth. Leveraging the power of Node.JS, we meticulously replicated the existing product's API protocol, ensuring seamless integration into the ecosystem.
Also, we harnessed the potential of the revitalized middleware, elevating it into an independent product designed to gather fitness metrics, not only for our client but also for a broader audience.

Another long-standing client approached us with a new project - a Stair Climbing Machine that required an Android application to fully control its functionalities via Serial-Port.
In this project, our task was further complicated by unforeseen risks associated with the hardware, as the giant 3-meter (with a person) and 230-kilogram (without a person) staircase lift presented challenges not only during development but also in terms of storage and transportation.
We began the development process by creating a Dummy App, the sole purpose of which was to validate the protocol's correctness. After approximately one sprint of development, we completed the Dummy App and realized that the data received was still not entirely accurate, not adhering to the specified protocol, and some functionalities were not working.
We promptly contacted the Chinese contractor of the client and explained the issue. During the call, all participants understood that an incorrect protocol had been provided to us. After receiving the new, correct protocol, we resumed our work.
Furthermore, the simulator provided to us did not meet the promised specifications; it was not a production unit. The display characteristics differed significantly, as we received a test display with entirely different dimensions and other components. The dimensions of certain parts also varied between the simulator and the actual units, for instance, the sizes of steps and the number of physical controllers were different. Additionally, we discovered that the display used an outdated version of Android (and not the stock Android).
To address these challenges, we had to develop not just a simple application but a custom shell specifically tailored for this unit (and that specific version of the operating system). We also had to adapt our application to work seamlessly with this unique combination of hardware and OS, which required extensive efforts to optimize its performance. Moreover, considering the project's nature, we incorporated OTA (Over-The-Air) capabilities to facilitate ongoing support and development even after delivering the units to the client.
Stormotion is currently working on a branded application that connects to smart batteries via Bluetooth. The app allows users to access essential battery information like charge levels and remaining runtime, ensuring a user-friendly experience. Our client sells these smart batteries, which are manufactured by a Chinese factory.
In the realm of smart battery sales, our valued client was confronted with a major predicament. Collaborating with a separate Chinese factory for battery production, they faced an influx of subpar batteries riddled with defects. At the core of the issue was the Bluetooth-enabled Battery Management System (BMS) that churned out erroneous metrics, leading to user frustration and inundation of support requests from distressed customers.
The culprits behind the flawed batteries were manifold:
In the face of these daunting challenges, our expertise came to the forefront, and we took decisive action:

Among our clients, there is a company that manufactures a diverse range of fitness equipment, from cycling machines to rowing machines and treadmills. When they approached us to develop a Workout-App for their innovative line of fitness machines, we eagerly embraced the opportunity to create a transformative solution.
However, what seemed like a straightforward project soon turned into a perplexing puzzle. At the outset, we underestimated the risks associated with integrating BLE modules into our application. Our client provided us with information that the devices operated on a single protocol and furnished us with what they believed to be the correct protocol.
Yet, when we implemented it, we encountered a staggering reality - only a third of the devices were transmitting data correctly. To our dismay, it became apparent that the devices actually operated on not one, but three different protocols (and, considering certain variations, even four).
Faced with pressing deadlines and non-functional devices, our client's Chinese manufacturer adamantly insisted that all devices operated on a single protocol, leading to a circular debate that impeded progress.
Due to the tight deadlines we were facing, we decided to take two approaches to resolve the issue. Firstly, we requested our client to directly contact their Chinese manufacturers to obtain information about the protocols used in the devices.
At the same time, we initiated a Reverse Engineering process. Our goal was to analyze the Bluetooth data received from the devices and compare it with publicly available protocols. By testing and logging data from multiple devices and examining the correlation between button presses and Bluetooth commands, we were able to identify three distinct groups of devices, each using a different protocol. This process took weeks of dedicated testing and analysis to gain a comprehensive understanding of these protocols.
We took the unconventional route of "fitting" the protocols ourselves due to the external constraints we faced. Although manufacturers should have provided accurate integration protocols, our commitment to our client's success pushed us to explore alternative methods to deliver the desired results.
In the end, the Chinese manufacturer confirmed the existence of three protocols. Finally, we were able to update the application, ensuring full functionality across all devices.

At Stormotion, we pride ourselves on delivering tailored software solutions that address our clients' unique needs. One such partnership involves collaborating with a company specializing in truck charging stations with branded payment terminals.
Our team was specifically responsible for developing the software to control these terminals.
Given the hardware-specific nature of this project, it came as no surprise that a typical set of challenges lay ahead. First and foremost, testing posed a significant hurdle as precisely replicating the required environment was nearly impossible. Despite our best efforts to approximate it, there remained a risk of overlooking critical issues in the production environment.
Secondly, updates posed a dilemma. With no physical access to the devices post-launch, releasing new versions and promptly addressing bugs became a logistical challenge. Additionally, we had to forego the conventional approach of developing for the latest Android platform. Instead, we had to design the application for a specific, outdated Android version that might not support popular libraries and various SDKs.
Moreover, we confronted UX-related hurdles as the software's end-users - truck drivers - were not tech-savvy individuals. Our utmost priority was to create an intuitively simple user experience that would empower seamless interaction with the terminals. Compounded by the limited screen real estate (3.5", 320 x 480 pixels) on the terminal, arranging content to optimize readability presented an additional challenge.
First and foremost, we prioritized remote updates. Implementing this crucial functionality allowed us to maintain support and seamlessly upgrade the system even after the terminals were deployed in the field. Remote updates would be facilitated through the hardware vendor, providing us with the assurance of continued adaptability and evolution.
To minimize external dependencies and mitigate the risk of component deprecation, we made strategic decisions to reduce reliance on third-party libraries and SDKs, thereby ensuring greater control over the system's stability and longevity.
Concerning design, simplicity became our guiding principle. We streamlined the application to just three screens, ensuring a user-friendly experience that minimized complexity. Action buttons and content elements were kept to a minimum, further enhancing usability and ensuring truck drivers could interact effortlessly with the terminals.
The challenge of fonts loomed large, given the client's brand guidelines that favored serif fonts, which posed readability issues on low-resolution screens. We rose to this challenge by conducting a careful search for an alternative font that harmoniously aligned with the client's corporate identity while preserving readability.

Once, a client approached us with a vision to develop a program with motion recognition capabilities using camera analysis based on ML. The primary goal of this application was to track users' movements during simple physical exercises and ensure they adhered to the correct form and repetition count.
The foundation of the application was built on React Native, providing a dynamic and cross-platform framework. However, the client sought to integrate an existing Python-based motion recognition module, which necessitated transpilation to Kotlin and Swift. The decision to port the logic natively stemmed from the desire to enhance performance and responsiveness.
Yet, integrating the native module with the React Native application posed a unique set of challenges. The project called for an exceptional blend of expertise, merging diverse technologies cohesively.
To solve this difficult problem, our team formulated an ingenious solution: the development of separate RN Bridges for iOS and Android. These bridges served as the gateway, allowing seamless integration between the native modules and the React Native application. By leveraging React Native, the project reaped the benefits of cost-effectiveness and cross-platform compatibility. At the same time, shifting critical motion recognition logic to the native side elevated the application's performance and responsiveness.
