IoT Solutions & Embedded Systems
- Firmware on ESP32, STM32, nRF and Raspberry Pi
- Secure MQTT telemetry with TLS and per-device certificates
- AWS IoT Core, Azure IoT Hub, EMQX and Mosquitto
- Time-series storage, fleet dashboards and OTA updates
Why IoT & Embedded with VN Softverg
Connected devices only create value when the whole chain works: reliable firmware on the device, secure connectivity, a cloud backend that can ingest and store high-volume telemetry, and dashboards and alerts that people actually use. We engineer that full chain.
On the device side, we write lightweight firmware in C and C++ on FreeRTOS and Zephyr for ESP32, STM32, Nordic nRF and Raspberry Pi platforms, covering sensor drivers, power management and over-the-air updates. Devices communicate over Wi-Fi, BLE, LoRaWAN or cellular using MQTT secured with TLS and per-device certificates.
In the cloud, we build ingestion on AWS IoT Core, Azure IoT Hub or self-hosted brokers like EMQX and Mosquitto, store data in time-series databases such as InfluxDB and TimescaleDB, and deliver fleet management, analytics and alerting through Grafana or custom web and mobile dashboards.
Everything you need, under one roof
Embedded Firmware Development
Real-time firmware in C/C++ on FreeRTOS and Zephyr, with sensor drivers, low-power modes and robust error recovery.
- Firmware source code
- Hardware abstraction and driver layer
- Power consumption profile
Device Connectivity
Wi-Fi, Bluetooth Low Energy, LoRaWAN, Modbus and cellular (LTE-M / NB-IoT) connectivity with offline buffering and reconnection logic.
- Connectivity stack configuration
- Offline buffering and retry logic
- Gateway integration
Secure Telemetry Pipelines
MQTT and CoAP messaging secured with TLS, X.509 device certificates and fine-grained topic permissions.
- Broker and topic architecture
- Device provisioning and certificate workflow
- Security configuration review
Time-Series Ingestion & Storage
Scalable ingestion into InfluxDB, TimescaleDB or cloud-native stores, with retention policies and downsampling for long-term analysis.
- Ingestion service
- Time-series schema and retention policies
- Data export APIs
Fleet Dashboards & Alerting
Grafana or custom dashboards showing device health, live readings and trends, with threshold and anomaly alerts via email, SMS or Slack.
- Fleet monitoring dashboards
- Alert rules and notification routing
- Device health reports
OTA Updates & Device Management
Remote configuration, staged over-the-air firmware rollouts with rollback, and device lifecycle management at fleet scale.
- OTA update pipeline
- Staged rollout and rollback procedure
- Device registry and management console
Measurable from day one
All device-to-cloud traffic encrypted with per-device credentials.
Firmware updates released to small device groups first, with rollback.
Device-to-dashboard latency goal for real-time readings.
Devices store readings locally and resend after connectivity loss.
