Firmware That Connects Reliably, Every Time
Embedded Software, Connectivity & OTA Updates
A device is only as good as the code running on it. We write the embedded firmware, connectivity stack, and over-the-air update system that keep your product reliable in the field.
The Challenge
Why Connected Devices Fail in the Field
- ✗Firmware drops its cloud connection and never reconnects automatically
- ✗No OTA update path, a bug fix means a physical recall
- ✗Power management is an afterthought, draining battery-powered devices fast
- ✗Connectivity protocol choice doesn't match the deployment environment
- ✗No device provisioning strategy for fleets beyond a handful of units
Our Approach
What We Build
- ✓C/C++ embedded firmware for microcontroller-based connected devices
- ✓Reliable device-to-cloud connectivity using MQTT, CoAP, or HTTPS
- ✓Over-the-air (OTA) update systems with rollback safety
- ✓Power-efficient firmware architecture for battery-powered devices
- ✓Secure device provisioning and authentication for fleet deployment
Use Cases
What We Build For You
MQTT Connectivity Firmware
Write firmware establishing reliable, auto-reconnecting MQTT connections between devices and cloud brokers.
OTA Update Systems
Build secure over-the-air firmware update pipelines with staged rollouts and automatic rollback on failure.
Battery-Powered Sensor Firmware
Engineer low-power firmware using sleep cycles and duty cycling to extend field battery life for remote sensors.
BLE-to-Cloud Bridging
Develop firmware and gateway software bridging Bluetooth Low Energy devices to cloud platforms via a hub.
LoRaWAN Device Firmware
Build firmware for long-range, low-power sensor networks using LoRaWAN for agriculture or utility deployments.
Secure Device Provisioning
Implement certificate-based device identity and provisioning so each unit authenticates securely at first boot.
Our Process
Step-by-Step Development Process
01
Requirements & Platform Selection
We review your hardware specs, power budget, and connectivity needs to select the microcontroller and RTOS.
02
Firmware Architecture
We design the firmware architecture, including connectivity, power management, and update strategy.
03
Firmware Development
We write and unit-test the embedded C/C++ firmware against your target hardware or dev boards.
04
Connectivity & OTA Integration
We implement and test cloud connectivity and the over-the-air update pipeline end to end.
05
Field Testing & Handoff
We validate firmware under real-world conditions and hand off documented, maintainable source code.
Technology
Our Stack
A typical firmware development project here uses C/C++, FreeRTOS, MQTT and LoRaWAN. We confirm the final choices with you at scoping, based on the systems you already run and the constraints you have.
FAQ
Frequently Asked Questions
Do you design or manufacture the circuit board the firmware runs on?
No. WORKFLOX writes embedded software and firmware. We do not design or fabricate PCBs or manufacture physical devices in-house. We work directly with your hardware engineering team, or a trusted hardware manufacturing partner we can introduce you to, to make sure firmware and board design align.
What microcontrollers do you write firmware for?
We most commonly work with ESP32, STM32, and Nordic nRF series microcontrollers, using FreeRTOS or Zephyr depending on the power and real-time requirements of the project. We scope the exact platform during discovery based on your connectivity and power needs.
Can you fix or take over firmware someone else started?
Yes. A significant share of our firmware engagements are takeovers of an existing codebase: usually to fix unreliable connectivity, add OTA update capability, or address a battery life issue that the original firmware didn't account for.
How do OTA updates avoid bricking a device if something goes wrong?
We implement staged rollouts and A/B partition schemes so a failed update automatically rolls back to the last known-good firmware image, rather than leaving the device unresponsive.
What does a firmware development project cost?
A connectivity and OTA firmware build for a single device type typically costs $8,000–$17,000. More complex projects involving custom protocols, power optimization, and multi-device fleets range $17,000–$27,000.
Firmware & Embedded Software Development in USA, UAE & Saudi Arabia
WORKFLOX engineers embedded firmware and device connectivity software for hardware teams and product companies across the GCC, US, and UK. We are firmware and embedded software specialists, not a PCB design or manufacturing house. We work alongside your hardware engineers or a hardware manufacturing partner to make sure the firmware and physical board come together as one reliable product.
Connectivity and OTA Updates Built to Survive Real-World Conditions
The gap between a firmware demo and a product that survives eighteen months in the field is reconnection logic, power management, and safe update handling. We build all three in from the start, using proven RTOS platforms and staged OTA rollouts rather than bolting on reliability after a field failure.
