+
+   The configuration option **BT_CTRL_BLE_MAX_ACT** defines the maximum number of Bluetooth LE activities that the controller can handle simultaneously. Each Bluetooth LE activity consumes one resource, including:
+
+   - Connections
+   - Advertising
+   - Scanning
+   - Periodic sync
+
+   Therefore, this parameter should be configured as follows:
+
+   **Maximum connections + required advertising, scanning and periodic sync instances**
+
+   **Example:** If the Host supports up to 8 connections, and the application requires 1 advertising instance and 1 scanning instance concurrently, set **BT_CTRL_BLE_MAX_ACT** to 10 (8 + 1 + 1).
+
+.. only:: not esp32 and not esp32c3 and not esp32s3
+
+   - No controller-related SDK configuration is required.

+
+   - 连接
+   - 广播
