:description: Instructions for setting up ESP32 bluetooth low energy device trackers using ESPHome.
|

|
|
|
|
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.
|
|
|
|
.. _config-esp32_ble_tracker:
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
|
|
- **scan_parameters** (*Optional*): Advanced parameters for configuring the scan behavior of the ESP32.
|
|
See also `this guide by Texas Instruments <https://dev.ti.com/tirex/explore/content/simplelink_academy_cc2640r2sdk_5_10_02_00/modules/blestack/ble_scan_adv_basic/ble_scan_adv_basic.html#scanning-basics>`__
|
|
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). Defaults to ``30ms``
|
|
- **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 bit more. Some devices don't need this, in that case
|
|
you can save power and RF pollution by setting it to ``false``. Defaults to ``true``.
|
|
- **continuous** (*Optional*, boolean): Whether to scan continuously (forever) or to only scan when
|
|
asked to start a scan (with start_scan action). Defaults to ``true``.
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID for this ESP32 BLE Hub.
|
|
|
|
Automations:
|
|
|
|
- **on_ble_advertise** (*Optional*, :ref:`Automation <automation>`): An automation to perform
|
|
when a Bluetooth advertising is received. See :ref:`esp32_ble_tracker-on_ble_advertise`.
|
|
- **on_ble_manufacturer_data_advertise** (*Optional*, :ref:`Automation <automation>`): An automation to
|
|
perform when a Bluetooth advertising with manufacturer data is received. See
|
|
:ref:`esp32_ble_tracker-on_ble_manufacturer_data_advertise`.
|
|
- **on_ble_service_data_advertise** (*Optional*, :ref:`Automation <automation>`): An automation to
|
|
perform when a Bluetooth advertising with service data is received. See
|
|
:ref:`esp32_ble_tracker-on_ble_service_data_advertise`.
|
|
- **on_scan_end** (*Optional*, :ref:`Automation <automation>`): An automation to perform when
|
|
a BLE scan has completed (the duration of the scan). This works with continuous set to true or false.
