Your firmware development roadmap with Yalantis
Discovery and hardware analysis
Our team studies your device requirements and hardware constraints in the context of how the device will operate. We define how firmware should interact with sensors, connectivity modules, and external systems.
- Clear understanding of hardware limitations and capabilities
- Defined performance, power, and memory constraints
- Early identification of integration and compliance risks
Firmware architecture design
We design firmware architecture based on your device class and use case. The architecture defines the execution model, whether bare-metal or RTOS-based. It also sets how the device communicates and how updates are handled.
- Architecture tailored to your hardware and workload
- Defined communication between device, edge, and cloud
- Built-in support for OTA updates and diagnostics
- Modular codebase structure that supports future feature additions
Hardware validation and prototyping
Yalantis tests firmware on real hardware to confirm stable behavior under actual conditions. The team validates sensor interaction and checks communication reliability across supported interfaces. If the project requires to verify component choices, we build functional prototypes to test different options before a full-scale development begins.
- Verified sensor integration and data accuracy
- Stable communication across all supported interfaces
- Component and interface decisions validated on real hardware
- Early detection of hardware-related issues
Firmware development and integration
Our engineers implement device logic and control flows, then connect firmware with external systems. The focus stays on predictable behavior and efficient use of device resources.
- Predictable performance under constrained resources
- Continuous testing to prevent regressions
- Smooth integration with cloud or edge systems
Deployment and lifecycle support
We prepare firmware for production and set up secure OTA updates. Even after that our team supports devices in the field through monitoring and controlled updates.
- Secure OTA updates with rollback protection
- Remote diagnostics and issue resolution
- Version control across deployed device fleets
- Ongoing improvements without disrupting devices in operation

FAQ
-
Can you improve or modernize existing firmware?
Yes. Our team audits existing firmware, identifies bottlenecks, and improves stability, performance, and compatibility. We can also restructure firmware to support OTA updates and new features without requiring a full hardware redesign.
-
How do you ensure firmware stability in production?
We validate firmware on real hardware under expected operating conditions. The process includes stress testing, fault injection, and long-run stability checks. We also implement diagnostics and logging to maintain reliable firmware behavior after deployment.
-
Do you work with legacy or outdated hardware and firmware?
Yes. We work with legacy MCUs and constrained environments where hardware cannot be replaced. Our team audits existing firmware, stabilizes critical components, and improves performance without breaking compatibility.
When needed, we refactor parts of the system or introduce low-level firmware improvements to extend device lifespan. We can also prepare legacy systems for OTA updates and gradual modernization as part of broader firmware development solutions.
-
How do you prevent devices from breaking during firmware updates?
We design OTA mechanisms with rollback support and staged rollouts. Firmware is validated before deployment and monitored during updates. If an issue occurs, devices automatically revert to a stable version, which protects hardware devices from becoming unusable.
-
What are the main risks in firmware projects, and how do you handle them?
Most failures come from unstable hardware integration, poor memory management, or unsafe update logic. We reduce these risks through early hardware validation, controlled resource usage, and structured firmware development process that includes real-device testing before release.
-
How do you ensure firmware works reliably in real environments, not just in tests?
We test firmware on actual devices under expected operating conditions, including unstable connectivity, temperature changes, and long runtimes. This approach ensures reliable firmware behavior outside controlled lab environments.
-
How do you design firmware for devices with limited memory and power?
We build low-level firmware that operates within strict memory and power constraints. That includes efficient scheduling, optimized memory usage, and controlled peripheral access to maintain stable device performance over time.
-
Can firmware be updated after devices are deployed in the field?
Yes. We implement secure OTA pipelines that allow controlled updates without physical access. These updates include validation, version control, and rollback mechanisms as part of long-term firmware development solutions.
-
What is your tech stack for firmware design and development?
We use Rust, C, and C++ to deliver robust, high-performance firmware tailored to each device. As a firmware design company, we’ve built a strong track record helping clients bring secure and scalable solutions to life. Our firmware design services cover everything from low-level hardware control to full system integration. We often work with platforms like STM32, ESP32, and NRF52, and support protocols like BLE, Zigbee, and LoRaWAN, depending on what your product needs.
