|
|
|
The ``esp32_ble_tracker`` component creates a global hub so that you can track bluetooth low
|
|
energy devices using your ESP32 node.
|
|
|
|
See :ref:`Setting up devices <esp32_ble_tracker-setting_up_devices>`
|
|
for information on how you can find out the MAC address of a device and track it using ESPHome.

.. note::
|
|
|
|
The first time this component is enabled for an ESP32, the code partition needs to be
|
|
resized. Please flash the ESP32 via USB when adding this to your configuration. After that,
|
|
you can use OTA updates again.
|
|
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
|
|
- **scan_parameters** (*Optional*): Advanced parameters for configuring the scan behavior of the ESP32.
|
|
See also `this guide by Texas 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.
