Challenges & Solutions

Challenge 1: Reliable Communication with BLE Sensors in Industrial Environments

The Problem: Large factories often present connectivity issues due to metal structures, interference, and distance. Maintaining a stable connection with BLE sensors in such conditions posed a significant challenge.
Our Solution: We implemented a robust BLE communication protocol with adaptive reconnection logic and signal monitoring. The apps continuously check signal strength and automatically re-establish connection if interrupted, ensuring uninterrupted data flow during monitoring and configuration.

Challenge 2: Presenting Complex Vibration Data on a Mobile Interface

The Problem: Translating technical data like FFTs and waveform signals into something readable and actionable on a small mobile screen was a major UX challenge, especially for technicians working on-site.
Our Solution: We designed a clean, mobile-first UI with simplified graphing tools and visual overlays. Important data is highlighted with minimal clutter, while advanced users can drill down for deeper analysis. The result is a balance between accessibility for new users and depth for experienced engineers.

Challenge 3: Remote Sensor Configuration and Firmware Updates

The Problem: Field teams needed the ability to update and configure sensors without removing them from machines or relying on desktop software, especially in time-sensitive or remote situations.
Our Solution: We built Zark Update as a dedicated tool for mobile-based sensor management. It allows users to wirelessly update firmware, adjust settings, and manage multiple sensors through a user-friendly interface—saving time, reducing manual labor, and preventing operational downtime.

Our Work

At Mirastart, we partnered with the Zark team to design and engineer a mobile-first solution that brings real-time vibration monitoring and sensor configuration into the hands of industrial maintenance teams. Our focus was on delivering a clean, reliable experience that simplifies complex diagnostics and enhances operational efficiency on the factory floor.

Discovery & Strategy

We started by understanding the real-world challenges faced by factory technicians and maintenance engineers. Our discovery process included identifying gaps in existing vibration monitoring workflows and understanding the technical constraints of BLE sensor integration. By mapping out the user journey and aligning it with sensor hardware capabilities, we defined a focused strategy to deliver a practical, mobile-first solution. This laid the foundation for a product that would not only meet functional requirements but also support seamless adoption in high-pressure industrial environments.

Our design approach centered on clarity, speed, and usability. We created a mobile-first interface that simplifies the presentation of complex vibration data like FFTs and time waveforms. Visual feedback, clear iconography, and technician-friendly flows were key in making the tools intuitive for both experienced engineers and new users. The result is a lightweight yet powerful experience that minimizes friction while maximizing operational insight, even in fast-paced or low-connectivity environments.

We engineered both Zark NI and Zark Update to deliver reliable BLE communication, secure data transfer, and real-time performance in challenging factory settings. The mobile applications were built using scalable frameworks and optimized for low-latency interactions with BLE sensors. Zark NI was focused on live monitoring and analysis, while Zark Update handled remote sensor configuration and firmware management. Our backend solutions supported efficient data handling, modular growth, and seamless syncing across devices.

To ensure the apps could withstand real-world use, we performed rigorous testing across a range of industrial conditions and device types. This included BLE stress testing, usability feedback from field technicians, and performance checks under limited network conditions. We optimized the user interface for clarity and responsiveness, and validated that sensor communication remained stable even in signal-heavy environments. Feedback from test sessions directly influenced refinements in both functionality and flow.

With both Zark NI and Zark Update ready for release, we focused on delivering a smooth and strategic deployment. We prepared App Store listings, coordinated version control, and ensured compliance with platform guidelines. A phased rollout approach was used to monitor early user feedback, address edge cases, and ensure system stability under real-world conditions. Support resources, including onboarding guides and internal documentation, were developed to assist factory teams with adoption. By combining technical readiness with thoughtful user enablement, we set the foundation for a successful launch and ongoing growth across industrial environments.

Business Outcomes

Zark NI and Zark Update have introduced a practical, mobile-first solution that transforms how industrial teams monitor and maintain factory equipment. By replacing outdated hardware and manual workflows with real-time vibration analysis and wireless sensor configuration, the platform improves operational efficiency, reduces unplanned downtime, and supports predictive maintenance strategies at scale.

Improved Equipment Monitoring Accuracy

Factory teams now have access to consistent, real-time insights into equipment health, allowing them to detect issues early and take action before failures occur. The integration of BLE sensors with mobile analysis tools has significantly enhanced the reliability of vibration diagnostics.

Mobile-based tools eliminate the need for bulky hardware or desktop software, enabling technicians to complete diagnostics and sensor configurations directly on the factory floor. This has led to faster maintenance cycles and fewer interruptions in production.

By enabling proactive maintenance through early fault detection, the platform helps factories minimize unexpected downtime. This contributes to smoother operations, longer equipment lifespan, and reduced emergency repair costs.

With Zark Update, managing large fleets of BLE sensors is faster and more efficient. Technicians can update firmware, modify settings, and resolve issues without taking sensors offline, improving consistency and scalability across industrial sites.

The success of the initial deployment creates opportunities for integration with broader factory systems, including SCADA platforms, ERP software, and industrial analytics dashboards. The modular architecture supports expansion into more advanced condition monitoring, asset tracking, and enterprise-level reporting.
