:description: Instructions for setting up Improv via BLE in ESPHome.
:image: improv-social.png
The esp32_improv component in ESPHome implements the open Improv standard
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- authorizer (Required, :ref:`config-id`): A :doc:`binary sensor <binary_sensor/index>` to authorize with.
Also accepts
none/falseto 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.
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.
