Bluetooth Device Count

computed from raw feature: cortex.raw.bluetooth

Description

Bluetooth device count sums the number of bluetooth device connections.

Optional or required kwargs

• start: (int, units: ms) the start time.
• end: (int, units: ms) the end time.
• resolution: (int, units: ms, default: 1 day = 86400000 ms) the resolution over which to compute features.

Data

• timestamp: (int, units: ms) the start time of each bin of size kwargs['resolution'].
• value: (int, units: None) the number of unique bluetooth devices.

Example

cortex.secondary.bluetooth_device_count.bluetooth_device_count(id="U1234567890", start=1607072400000, end=1609232400001, resolution=86400000)

Output:

{
  'timestamp': 1607072400000,
  'duration': 5616000000,
  'resolution': 86400000,
  'data': [
           {'timestamp': 1607072400000, 'value': 0},
           {'timestamp': 1607331600000, 'value': 6},
                 .
                 .
                 .
           {'timestamp': 1609232400000, 'value': 3}
          ]
