Firmware & Embedded Development Services
Firmware development is the embedded software that runs directly on a device's microcontroller, controlling sensors, radios, and real-time behavior. Raonebytes provides firmware and embedded systems development for hardware teams worldwide — bare-metal and RTOS firmware, drivers, connectivity, and OTA — taking devices from prototype to production with fixed quotes and an NDA on every project.
What's included
Bare-metal firmware
Efficient, register-level firmware for microcontrollers where footprint and power matter.
RTOS development
FreeRTOS, Zephyr, and similar real-time systems for concurrent, deterministic behavior.
Device drivers
Drivers and HAL layers for sensors, displays, radios, and peripherals over I2C, SPI, UART, and USB.
Connectivity stacks
BLE, Wi-Fi, cellular, and LoRa integration with cloud or mobile back-ends.
OTA & security
Secure over-the-air updates, bootloaders, and secure-boot for fielded devices.
Test & integration
Hardware-in-the-loop testing, logging, and integration with your electronics and apps.
Our process
Spec
We define functional requirements, target MCU, and constraints, then return a fixed quote — typically within 24 hours.
Design
Firmware architecture, driver plan, and connectivity strategy with milestone reviews.
Build
We implement firmware, drivers, and update mechanisms against your hardware.
Test
Functional and hardware-in-the-loop testing, power profiling, and field-readiness checks.
Ship
Documented, maintainable source and a production firmware image.
Why teams choose Raonebytes
Time-zone overlap
Responsive, overlapping working hours for live reviews and debugging.
Fixed quotes in 24 hours
Scoped, transparent pricing before any firmware work begins.
NDA on every project
We sign an NDA before reviewing your hardware or code.
CE / FCC aware
Radio and power behavior designed with CE, FCC, and international compliance in mind.
Prototype to production
From bring-up firmware to a maintainable production image.
Offshore value
Bengaluru-based embedded engineering at rates that stretch your budget.
Frequently asked questions
How much do firmware development services cost?
Cost scales with the number of peripherals, connectivity, and real-time complexity. We scope every project and return a fixed quote — usually within 24 hours — so you approve the price before work begins.
How long does embedded firmware development take?
A focused firmware build typically takes 4–8 weeks, depending on the peripherals, connectivity stacks, and certification needs involved. Larger systems with OTA and security take longer.
Which microcontrollers and RTOSes do you support?
We work across common MCU families (ARM Cortex-M, ESP32, STM32, Nordic nRF, and more) and real-time operating systems including FreeRTOS and Zephyr, as well as bare-metal designs.
Can you add firmware to existing hardware?
Yes. We can develop or extend firmware for boards you already have, including bring-up, driver work, connectivity, and OTA on existing designs.
Do you work with international teams under NDA?
Yes. We serve hardware teams worldwide with daytime overlap and sign an NDA on every project before any code or hardware detail is shared.
