Embedded & firmware
Firmware with explicit states, reliable communication and useful diagnostics.
We develop and integrate embedded firmware for connected devices, with attention to configuration, error handling, protocol behavior and the tools needed to validate the complete system.
Our approach
Make device behavior observable and maintainable.
Firmware is easier to integrate when state, timing, configuration and faults are defined rather than implied. We structure device behavior around clear interfaces and evidence from bench testing.
Capabilities
What we can support
- ESP32 and ESP32-S3 application firmware
- BLE/GATT, Wi-Fi, UART and Modbus RTU communication
- Sensor, actuator and peripheral integration
- Persistent settings, calibration and device configuration
- Diagnostic logging, fault handling and update planning
Handover
Typical deliverables
- Firmware architecture and configuration model
- Drivers, communication services and application logic
- Protocol definitions and integration examples
- Bench-test utilities and diagnostic output
- Build instructions, release package and handover notes
Electronic schematics and PCB layout can be delivered with our electronics design partner. SYANKOR remains accountable for the agreed firmware and integration scope, with interfaces reviewed before implementation.
Frequently asked questions
What teams usually ask first.
Can you develop firmware for an existing PCB?
Yes. We first review the schematic, component choices, available hardware, programming method and current firmware state.
Can you integrate a device with mobile or desktop software?
Yes. Device protocol and software behavior can be developed as one connected system, including test and diagnostic tools.
Do you provide bench validation?
Yes. Validation can cover the agreed communication paths, sensor behavior, configuration, recovery states and representative operating scenarios.
ESP32 routes
Build the product—or review what exists.
Use the development path for a defined firmware/electronics workstream, or start with a fixed-scope production-readiness review before a pilot build.
Start a conversation
Have a product challenge to work through?
Share your current stage, technical constraints and expected outcome. We will help define a practical next step.
Embedded Linux hardware and firmware development
From custom PCB and Linux bring-up to drivers and device applications.
SYANKOR can own a connected work package across conventional hardware, Linux porting, device drivers, firmware and application software, with specialist partners used transparently where the scope requires them.
