BLE Client Binary Output

:description: Writes a binary value to a BLE device.

|
|
|
|
The ``ble_client`` component is a output that can write a binary value to service characteristics of BLE devices.
|
|
|
|
For more information on BLE services and characteristics, see :doc:`/components/ble_client`.
|
|
|
|
.. 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.

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 write to.
|
|
- **id** (*Optional*, :ref:`config-id`): The ID to use for code generation, and for reference by dependent components.
|
|
- **require_response** (*Optional*, boolean): Control whether to require a remote response from the device when writing.
|
|
Whether or not this is required will vary by device. Defaults to ``false``
|
|
- All other options from :ref:`Output <config-output>`.
