A leading European biotech company turned to IronCodeLabs when its critical medical IoT transmitters faced obsolescence. Years of lost documentation, vendor lock-in, and outdated hardware threatened both compliance and continuity. They hired IronCodeLabs for our rare blend of legacy expertise and AI-driven modernisation to restore functionality, reduce risk, and secure the future of their technology.
IronCodeLabs designed a modernisation strategy that combined firmware reverse engineering, hardware redesign, and AI-assisted diagnostics to restore functionality while ensuring long-term scalability. By adopting a phased roadmap - from system assessment to proof-of-concept and continuous optimisation - we delivered a secure, compliant, and sustainable transformation framework tailored to the client’s critical medical IoT environment.
Our strategy emphasised vendor independence, ensuring the client was no longer tied to proprietary firmware or locked toolchains. This gave them full control over their technology lifecycle and the flexibility to adapt as requirements evolve.
We also embedded compliance and resilience into every phase of the strategy, aligning modernisation with strict biotech regulatory standards while introducing continuous monitoring to safeguard both performance and patient safety.
IronCodeLabs delivered this project through a structured, phased approach designed to minimise risk while maximising business impact. We began with a diagnostic assessment to map system dependencies, compliance gaps, and quick-win opportunities. From there, we built a tailored modernisation roadmap that prioritised vendor independence and long-term resilience. The next phase focused on execution and proof-of-concept delivery, where firmware reverse engineering, hardware redesign, and AI-assisted workflows were applied to restore transmitter functionality. Once stability was achieved, we moved into continuous optimisation, embedding monitoring, documentation, and compliance frameworks to ensure ongoing reliability. Finally, we created a scalable model for innovation, equipping the client with a repeatable playbook to extend modernisation across future devices. This phased approach ensured that transformation was delivered securely, predictably, and in full alignment with business and regulatory goals.
• Structured Roadmap; we began with a full diagnostic and designed a phased modernisation plan to align technology transformation with business and compliance goals.
• Secure Execution; through firmware reverse engineering, hardware redesign, and AI-assisted workflows, we delivered modernisation with zero disruption and reduced vendor dependency.
• Ongoing Optimisation; we embedded continuous monitoring, compliance frameworks, and a repeatable playbook, ensuring long-term resilience and scalability for future devices.
IronCodeLabs approached the project with a comprehensive modernisation strategy designed to restore functionality, remove vendor lock-in, and establish a sustainable development path. The solution was delivered in carefully managed phases to minimise risk and ensure compliance with strict biotech standards.
• Rebuilding the Development Environment; We reconstructed the FreeRTOS toolchain, SDKs, and debugging workflows, giving the client a fully functioning environment to support long-term development and maintenance.
• Firmware Reverse Engineering; by analysing and modifying legacy firmware, we overcame vendor-imposed constraints, extending device functionality and enabling future flexibility.
• Hardware Redesign for Flexibility; the voltage conditioning subsystem and other critical components were re-engineered to replace fixed constraints with programmable, adaptable solutions.
• Proof of Concept (PoC) Validation; using a dedicated test unit, we rapidly validated extended operation and simplified firmware modifications, proving viability within weeks.
• Compliance & Documentation; every stage of the process was aligned with biotech regulatory requirements, supported by detailed technical documentation to ensure repeatability and audit readiness.
Through this solution, IronCodeLabs transformed an outdated, locked-down system into a revived, scalable, and compliant platform. The client not only regained operational continuity but also gained full control of their technology lifecycle - positioning them to extend the life of their devices and scale innovation securely.
IronCodeLabs delivered measurable impact, turning a legacy liability into a sustainable, future-ready asset.
• Device Revival; dormant CGM transmitters were restored to full functionality, extending their operational life without disruption.
• Vendor Independence; proprietary firmware constraints were eliminated, giving the client full control over development and support.
• Extended Lifecycle; hardware redesign and firmware flexibility positioned the devices for long-term scalability and resilience.
• Compliance Assured; all modernisation steps were aligned with biotech regulations, ensuring audit readiness and patient safety.
• Sustainable Playbook; a repeatable framework and documentation package enabled ongoing maintenance and future modernisation across product lines.
Business Impact:
This project not only safeguarded critical medical IoT operations but also saved the client from costly hardware replacement programs. By redefining legacy transformation, IronCodeLabs gave the biotech leader the tools to scale confidently, reduce risk, and embrace innovation.
