Existing devices need connectivity
Retain control logic while adding collection, remote control, logs and cloud access.

Turn a working prototype
into a connected, maintainable product.
For equipment suppliers, integrators and smart-product teams, we develop firmware, drivers, protocols, gateways, host applications and cloud connectivity. Hardware resources, field conditions and failure modes guide software structure.
When these services help
After a device runs, reliability, connectivity and maintenance still need engineering.
A prototype validates a direction. Customer sites and production introduce weak networks, power loss, batch differences, remote updates and service diagnostics.
A development-board prototype needs productization
Missing fault recovery, versioning, production tests and long-run validation prevent direct customer delivery.
Protocols, peripherals and platform APIs are complex
Different teams own controllers, communication modules and business systems, leaving integration responsibility unclear.
After-sales support still requires site visits
Without logs, remote diagnostics, configuration and updates, even small issues require an engineer on site.
Development capabilities
Define firmware, communication, gateways, host applications and platform integration within one delivery scope.
Joint hardware design, certification and supply-chain work, if required, are specified separately in proposals and quotes to keep responsibilities clear.
MCU / RTOS firmware
Drivers, local control, scheduling, storage, fault recovery and low-power operation.
STM32 / ESP32 / FreeRTOS and other options assessed per projectLinux & edge applications
Device services, daemons, local databases, containers, logs and remote maintenance.
Linux / OpenWrt / Industrial PCs / Edge devicesCommunication & protocol adaptation
Serial, RS485, CAN, BLE, Wi-Fi, 4G, Modbus, MQTT and proprietary protocols.
Verify protocols, data frequency and exception handling firstHost applications & configuration tools
Device debugging, parameter configuration, charts, tests, batch flashing and production records.
Choose Windows or local web consoles for the scenarioOTA & remote diagnostics
Versions, signatures, staged rollouts, rollback, logs, fault codes and remote configuration.
Validate control risks and recovery paths firstIoT & business system integration
Map device properties, events, commands and alerts to platforms, apps or customer systems.
Device models / APIs / Work orders / DashboardsDevice, edge & cloud coordination
Clear responsibilities at every layer make device problems understandable on the platform.
Devices retain local control; the edge handles protocol conversion and offline recovery; the cloud manages operations; business systems manage orders, services and support.

How devices, gateways and cloud form a complete workflow
- Project background
- Existing controllers used a proprietary serial protocol, with status and faults visible only on site.
- First phase
- Select one device type to validate parsing, offline caching, remote status, alerts and work orders.
- System components
- Firmware adaptation, industrial gateway, device platform, service console and permission logs.
- Acceptance method
- Individually verify offline recovery, duplicates, command acknowledgements, alerts and rollback.
Project path & delivery
Validate the highest-risk hardware connection before expanding features and device coverage.
Prototypes, protocols, hardware batches and testing conditions directly affect firmware and field-project schedules. Technical validation provides a sounder basis for a full timeline.
Hardware, interfaces & current-state audit
Controllers, peripherals, schematics, protocols, existing code, field networks and control risks.
Driver, protocol or connectivity prototype
Choose the highest-risk path and create a minimal version that supports repeatable tests.
Firmware, gateway & platform integration
Develop versions, exception handling, logs, configuration, OTA and business APIs together.
Testing, production & service documentation
Source code, configuration, test records, flashing guides, version tables and maintenance suggestions.
Core acceptance checks Long-running stability and recovery are verifiable Protocol data and control results are traceable Failed OTA updates have a safe recovery path Source code and production/maintenance materials are handed over as agreed
FAQ
Embedded systems & smart hardware FAQ
Can we start with a prototype but no complete technical documentation?
We can begin with feasibility assessment. Provide the prototype, controller and peripheral details, firmware notes, interface or communication information and control logic that must remain. Testing and site discussions can clarify missing details.
Does the scope include PCB and mechanical design?
We directly handle embedded software, firmware, communication and platform integration. PCB, mechanical design, certification and supply-chain work are assessed for in-house or joint delivery, with responsibilities specified in the quote.
How are OTA and remote diagnostics implemented?
Design firmware partitions, signature checks, staged rollout, resumable downloads, failed-update rollback and version records, supported by logs, device status and remote commands.
What is needed between a prototype and a production-ready release?
Usually fault recovery, long-term stability, production flashing, configuration tools, testing standards, version control, service diagnostics and documentation, with further assessment of target costs and certification.
Already have a prototype, control board or device documentation?
Share the controller, interfaces, protocols, existing-code notes and field problem. We will assess whether to begin with firmware, a gateway or platform connectivity.
