Configuration variables:
------------------------
- **scan_interval** (*Optional*, :ref:`config-time`): The length of each scan.
If a device is not found within this time window, it will be marked as not present. Defaults to 300s.
- **scan_parameters** (*Optional*): Advanced parameters for configuring the scan behavior of the ESP32.
See also `this guide by Texax Instruments <http://dev.ti.com/tirex/content/simplelink_academy_cc2640r2sdk_1_12_01_16/modules/ble_scan_adv_basic/ble_scan_adv_basic.html#scanning>`__
for reference.
- **interval** (*Optional*, :ref:`config-time`): The interval between each consecutive scan window.
This is the time the ESP spends on each of the 3 BLE advertising channels.
Defaults to ``320ms``.
- **window** (*Optional*, :ref:`config-time`): The time the ESP is actively listening for packets
on a channel during each scan interval. If this is close to the ``interval`` value, the ESP will
spend more time listening to packets (but also consume more power).
- **duration** (*Optional*, :ref:`config-time`): The duration of each complete scan. This has no real
impact on the device but can be used to debug the BLE stack. Defaults to ``5min``.
- **active** (*Optional*, boolean): Whether to actively send scan requests to request more data
after having received an advertising packet. With some devices this is necessary to receive all data,
but also drains those devices' power a (tiny) bit more. Defaults to ``true``.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID for this ESP32 BLE Hub.
