         :SOC_WIFI_SUPPORTED: - 使用 Wi-Fi Protected Setup (WPS)、WPA2 EAP-TLS、Device Provisioning Protocol (DPP) 或 BSS Transition Management (BTM) 等功能时，Wi-Fi wpa_supplicant 组件可能会创建优先级较低的专用任务 (2)，这些任务并未固定在特定核心上执行。
         :SOC_BT_SUPPORTED: - :doc:`/api-reference/bluetooth/controller_vhci` 任务优先级较高 (23, ``ESP_TASK_BT_CONTROLLER_PRIO``) 且默认固定在核心 0 上执行（ :ref:`可配置 <{IDF_TARGET_CONTROLLER_CORE_CONFIG}>` ）。蓝牙控制器需要以低延迟响应请求，因此其任务应始终为最高优先级的任务之一并分配给单个 CPU 执行。
