System Architecture andData Management

A well-designed systeme architecture is essential for turning raw sensor data into actionable insights. The typical Bluetooth- enabled monitoring system contributes three tiers: thee sensor layer, thee gateway layer, and the cloud or on- premises data management platform.

Mutual TLS authentiation, where both the gateway and cloud server verify each text 's certificates, adds an extra layer of protection. Regularly rotate certificates andd keys; consider using a hardware security module (HSM) or secre element on gateways for key storage.
