ESP 主机主要功能支持状态
========================

:link_to_translation:`zh_CN:[中文]`

本文档介绍了乐鑫低功耗蓝牙主机 ESP-Bluedroid 和 ESP-NimBLE 主要功能的支持状态。
如果您计划将低功耗蓝牙控制器和主机跑在 {IDF_TARGET_NAME} 上，主机的功能支持可能会受限于控制器的功能支持状态，
请参阅 :doc:`{IDF_TARGET_NAME} 主要功能支持状态 <ble-feature-support-status>` 。

|supported_def|  **该功能已完成开发和内部测试。** [1]_

|experimental_def| **该功能已完成开发，正在进行内部测试。**
您可以探索这些功能以进行评估和反馈，但应注意可能出现的问题。

|developing_def| **该功能目前正在积极开发中， 预计在 YYYY/MM 月底之前支持。**
请关注此表以获得该功能的最新进展。
如果您确实有紧急的开发需求，请联系 `乐鑫客户支持团队 <https://www.espressif.com/zh-hans/contact-us/sales-questions>`__ 以了解是否可以进行功能试用。

|unsupported_def|  **该功能在此芯片上不支持。** 如果您有相关需求，请优先选择其他支持该功能的乐鑫芯片系列。
如果当前的乐鑫产品都无法满足您的需求，请联系 `乐鑫客户支持团队 <https://www.espressif.com/zh-hans/contact-us/sales-questions>`__ ，我们的研发团队会对您的需求进行内部的可行性评估。

|NA_def| 具有此标签的功能为一下类型：
    - **Controller-only 功能**：该功能仅存在于 HCI 层之下，且无法通过主机API配置或启用，例如 Advertising Channel Index 。
      此类功能不需要蓝牙主机的支持。
