IoT and connectivity engineering
Reliable links between devices, gateways and the cloud — with updates that can be delivered securely for the whole support period of the product.
· by BCF Embedded engineering team
Protocols we use
Chosen for range, power budget, data volume and the environment the device works in.
Wireless
- Bluetooth Low Energy
- Wi-Fi
- LoRa / LoRaWAN
- LTE-M / NB-IoT
Wired
- CAN
- RS-485
- Ethernet
- Modbus RTU/TCP
Application
- MQTT
- CoAP
- HTTPS / TLS
Secure OTA updates
Over-the-air updates are the only practical way to fix vulnerabilities in devices already in the field. We design update mechanisms with signed images, verification on the device and safe rollback after a failed install.
Security architecture and the CRA support-period requirement are covered in cybersecurity & CRA and secure boot and OTA.
Cloud integration
We build the device side of the integration: provisioning, authentication, message formats and offline buffering. Cloud platforms, dashboards and data pipelines are delivered together with BCF Cloud & Data.
Low-power design
- Sleep modes and wake-up sources designed with the hardware team
- Radio duty cycles and data batching matched to the battery budget
- Current measurements on real hardware, not estimates only
Security
TLS, device identity and key storage are part of the connectivity design from the start. Read more about our approach to embedded cybersecurity.
