Migration Of Data Logger App From Xamarin To .NET MAUI For Modern Sensor Insights [Case Study]

When your business operations depend on real-time sensor data, reliability isn’t a luxury — it’s mission-critical.

With the need for technological upgradation, one of our US-based clients — a leader in data loggers and remote monitoring systems manufacturing faced performance bottleneck with their aging Xamarin-iOS app. And with Microsoft officially pulling the plug on Xamarin, the case for modernization was no longer optional — it was compulsion.

Performance lags, limited platform support, and mounting tech debt made it clear: the status quo wasn’t sustainable. That’s where Rishabh Software stepped in to enable cross-platform data logger app upgradation from Xamarin to .NET MAUI for enhanced sensor data logging.

We didn’t just replicate the existing app — we upgraded it by using .NET MAUI. From seamless Bluetooth integration with MX401 sensors to dynamic reporting, robust SSO, and full cross-platform support, we delivered a modern mobile and desktop solution that’s faster, lighter, and fulfills every aspect of each native platform.

Here’s how we helped our client migrate data logger app from Xamarin to .NET MAUI to eliminate field inefficiencies and gear up for long-term scalability, without rewriting everything from scratch.

Project Overview

A leading US-based manufacturer of Data Loggers and Remote Monitoring Systems was on the lookout for a strategic technology partner to upgrade their legacy Xamarin-based iOS application into an enterprise-grade, cross-platform mobile and desktop solution using Microsoft’s .NET MAUI framework. The goal was to migrate from an outdated architecture to a more scalable, maintainable, and future-ready app environment.

Rishabh Software upgraded the data logger app from Xamarin to .NET MAUI and .NET 8, delivering a future-ready mobile app with seamless Bluetooth integration, dynamic report generation, Microsoft SSO authentication, and robust MVVM-Singleton architecture. The new app enhanced performance and security, improved UI/UX consistency across platforms, and laid the groundwork for scalable, long-term innovation in field operations.

Challenges

• Outdated Xamarin app hindered scalability, lacked modern UI/UX capabilities, and faced end-of-life support from Microsoft, making it a liability for long-term maintenance and innovation.
• Unreliable logger test reporting created inconsistencies and delays in field operations.
• Frequent BLE readout errors disrupted sensor data collection and reduced accuracy.
• Timeout issues during sessions led to data loss and poor user experience.
• Cluttered reporting interface made report review and sharing inefficient for users.

Solution

To assist the client transition from a depreciated Xamarin-based application to a modern, scalable mobile solution, Rishabh Software upgraded the platform using Microsoft’s .NET MAUI and .NET 8 for iOS. This migration established a unified development stack, improved maintainability, strengthened security compliance, and optimized runtime performance for long-term scalability.

Key Components of The Solution

Modular Development

The application was architected as a suite of independent, tightly scoped modules. This modular approach enhanced performance and made the system easier to manage, scale, and debug. Each module was designed with specific functionality to ensure clean separation of concerns and easier traceability during updates or enhancements.

Singleton & MVVM Architecture

During the migration, our expert team of developers relied on a hybrid architecture that combined Singleton and MVVM patterns to maintain code clarity and structure throughout the process. This architectural choice facilitated code reuse, simplified unit testing, and allowed for clear separation between UI and business logic, making future development more efficient.

Microsoft SSO Integration

To strengthen security and simplify access management, the team integrated Microsoft’s enterprise-grade Single Sign-On (SSO). This allowed users to authenticate securely through Mobile Device Management (MDM) policies, ensuring only authorized personnel could access the application and its data, aligning with enterprise compliance standards.

BLE Sensor Support (MX401)

A custom communication library was built to interface with Bluetooth Low Energy (BLE) sensors, specifically the MX401. This enabled seamless connectivity to capture real-time test data, monitor environmental conditions, trigger alarms, and generate monthly performance reports directly from the field.

Dynamic Report Generation

The app was enhanced with the ability to generate diagnostic reports in real time, across multiple formats including PDF and CSV. These reports could be uploaded securely to the cloud, streamlining workflows and ensuring data consistency and availability for stakeholders across the organization.

Benefits

• 40% boost in field efficiency through real-time sensor integration.
• 50% fewer readout/time-out errors, ensuring reliable data capture.
• 30% wider reach with cross-platform support.
• 100% security compliance via Microsoft SSO and MDM.
• 35% faster report generation and uploads for quicker decision-making.
