End-to-end embedded development from architecture to deployment
FreeRTOS and Zephyr-based architectures with preemptive scheduling, deterministic tasks, and fault isolation for mission-critical applications.
Multi-protocol wireless solutions—BLE, LoRaWAN, LTE Cat-1/4, Wi-Fi, Thread, Zigbee—with battery optimization and fleet-scale reliability.
Custom BSP layers, U-Boot bootloaders, A/B OTA systems with SWUpdate/RAUC, and heterogeneous Cortex-M + Cortex-A architectures.
AWS IoT Core integration, MQTT/LwM2M protocols, X.509 device identity, Fleet Provisioning, and manifest-driven observability layers.
CAN-FD, CAN, Modbus, RS-485 implementations with real-time decoding, bus arbitration, and stateful data processing.
Secure A/B updates with atomic verification, automatic rollback, signed bundles, and fleet-wide deployment orchestration.
Production-ready reference designs and customizable platforms
Battery-powered heterogeneous gateway (Cortex-M + Cortex-A55) with Yocto BSP, A/B OTA via SWUpdate, LTE CAT-1 modem management, and optimized low-power sleep modes.
Ultra-low-power FreeRTOS asset tag with concurrent LoRaWAN Class-A and BLE operation. 8-year CR2 battery life achieved through firmware optimization and custom ADR configuration.
FreeRTOS-based smart thermostat with RS-485 fieldbus communication, BLE provisioning, AWS IoT MQTT, signed A/B OTA, and adaptive PID control for VRF inverter systems.
Real-time CAN-FD decoder with Protobuf telemetry, LTE CAT-4 connectivity, GNSS positioning, and RAUC-based A/B Linux OTA with automatic rollback on health-check failure.
Ostrinium Technologies brings 10+ years of hands-on embedded systems expertise to your connected product development.
We've architected RTOS and Embedded Linux systems for resource-constrained devices across HVAC, industrial IoT, vehicle telematics, and asset tracking—owning everything from bootloaders to cloud telemetry.
Our approach: stay hands-on, shape architecture, and hunt down the failures that emerge at fleet scale. We don't just write firmware—we engineer systems that survive in the field.
6 patents in HVAC controls and adaptive systems
