芯科的EFR32BG2X系的蓝牙芯片在软件开发中“Bluetooth on-demand start”组件有什么作用？

该组件使应用程序能够按需启动或停止蓝牙协议栈。默认情况下构建中若未包含此组件，则蓝牙堆栈在初始化时自动启动，并且永远不会停止。若添加此组件：蓝牙协议栈直到调用sl_bt_system_start_bluetooth()才会运行。此功能的主要目的是DMP（低功耗蓝牙设备管理器（Device Management Profile））用例，在该用例中，蓝牙不是所有时间都需要，并且需要将资源释放给其他应用程序使用。可以使用sl_bt_system_stop_bluetooth()停止蓝牙协议栈，通过断开任何活动连接和停止任何进行中的广告和扫描来将蓝牙恢复到空闲状态。当蓝牙协议栈未运行时，除System之外的所有BGAPI类都不可用。
