BLE Beacon

Devices capture readings from BLE tags and determine if a BLE tag is in the same room by aggregating the readings and motion data from the built-in radar. This is useful for e.g., measuring time spent by caregivers in the respective rooms or skipping alarms while a caregiver is present.
