 Configuration variables:
 ------------------------
 
-- **ble_client_id** (**Required**, :ref:`config-id`): ID of the associated BLE client.
-- **service_uuid** (**Required**, UUID): UUID of the service on the device.
-- **characteristic_uuid** (**Required**, UUID): UUID of the service's characteristic to query.
-- **descriptor_uuid** (*Optional*, UUID): UUID of the characteristic's descriptor to query.
-- **id** (*Optional*, :ref:`config-id`): The ID to use for code generation, and for reference by dependent components.
-- **lambda** (*Optional*, :ref:`lambda <config-lambda>`): The lambda to use for converting a raw data
-  reading to a sensor value. See :ref:`ble-sensor-lambda` for more information.
-- **notify** (*Optional*, boolean): Instruct the server to send notifications for this
-  characteristic.
-- **update_interval** (*Optional*, :ref:`config-time`): The interval to poll the device.
-- All other options from :ref:`Sensor <config-sensor>`.
