Firmware Development
We write firmware that runs reliably for years. From bare-metal register programming to Zephyr RTOS, we build device software that handles real-world conditions, OTA updates, and production variance.
What We Deliver
Core capabilities
RTOS Application Development
Multi-threaded real-time firmware on Zephyr, FreeRTOS, and ThreadX, task scheduling, IPC, power management, watchdog systems.
Bare-Metal & Drivers
Register-level HAL/BSP development, peripheral drivers (SPI, I2C, UART, ADC, DMA), and custom bootloaders.
Connectivity Stacks
BLE (GATT, mesh), Wi-Fi, Zigbee, Thread, Matter, LoRaWAN, LTE/NB-IoT AT commands, MQTT/CoAP on embedded targets.
OTA / FOTA Systems
Secure firmware updates, MCUboot, dual-bank, delta patching, rollback, and server-side deployment management.
Protocol Implementation
Modbus RTU/TCP, DLMS/COSEM, OCPP 1.6J/2.0, SNMP, CAN/CANopen, and custom binary protocols.
Power Management
Sleep orchestration, duty cycling, low-power BLE, wake sources, battery monitoring, energy harvesting control.
Security Implementation
Secure boot chains, hardware crypto (AES, ECC, SHA), TLS/DTLS, certificate management, secure key storage.
Embedded Linux / Android
Yocto/Buildroot custom images, device tree, kernel modules, and Android AOSP HAL/BSP customization.
