:description: Instructions for setting up Improv via BLE in ESPHome.

|
|
|
|
The ``esp32_improv`` component in ESPHome implements the open `Improv standard <https://www.improv-wifi.com/>`__
|
|
for configuring Wi-Fi on an ESP32 device by using Bluetooth Low Energy (BLE) to receive the credentials.
|
|
|
|
The ``esp32_improv`` component will automatically set up the :doc:`BLE Server <esp32_ble>`.
|
|
|
|
.. 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.

# Example configuration entry

|
# ...

|
|

esp32_improv:
|
|
authorizer: binary_sensor_id
|
|
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **authorizer** (**Required**, :ref:`config-id`): A :doc:`binary sensor <binary_sensor/index>` to authorize with.
|
|
Also accepts ``none``/``false`` to skip authorization.
|
|
- **authorized_duration** (*Optional*, :ref:`config-time`): The amount of time until authorization times out and needs
|
|
to be re-authorized. Defaults to ``1min``.
|
|
- **status_indicator** (*Optional*, :ref:`config-id`): An :doc:`output <output/index>` to display feedback to the user.
|
|
- **identify_duration** (*Optional*, :ref:`config-time`): The amount of time to identify for. Defaults to ``10s``.
|
|
- **wifi_timeout** (*Optional*, :ref:`config-time`): The amount of time to wait before starting the improv service after Wi-Fi
|
|
is no longer connected. Defaults to ``1min``.
|
|
|
|
Status Indicator
|
|
----------------
|
|
|
|
The ``status_indicator`` has the following patterns:
|
|
|
|
- solid: The improv service is active and waiting to be authorized.
|
|
- blinking once per second: The improv service is awaiting credentials.
|
|
- blinking 3 times per second with a break in between: The identify command has been used by the client.
|
|
- blinking 5 times per second: Credentials are being verified and saved to the device.
|
|
- off: The improv service is not running.
