|
|
|
|
The ``ble_scanner`` text sensor platform lets you track reachable BLE devices.
|
|
|
|
See the :ref:`BLE Tracker Configuration variables <config-esp32_ble_tracker>` for instructions for setting up scan parameters.
|
|
|
|
The sensor platform is similar to :doc:`/components/sensor/ble_rssi` but in contrast to that platform, this text
|
|
sensor sends out all raw BLE scan information and does not filter devices.
|
|
|
|
The data this sensor publishes is intended to be processed by the remote (for example an MQTT client) and sends
|
|
the data in JSON format.
|
|
|
|
.. warning::
|
|
|
|
The BLE software stack on the ESP32 consumes a significant amount of RAM on the device.
|
|
|
|
**Crashes are likely to occur** if you include too many additional components in your device's
|
|
configuration. Memory-intensive components such as :doc:`/components/voice_assistant` and other
|
|
audio components are most likely to cause issues.
