我目前正尝试通过低功耗蓝牙将带有蓝牙 5.1 的英特尔 NUC 连接到我的手机。
当我从手机启动 BLE 扫描时，我找不到 NUC。当我运行常规蓝牙扫描时，我可以找到它。
此外，命令sudo hcitool lescanNUC 上的 I/O 错误。sudo hcitool 扫描效果很好。解决方案见这篇文章https://stackoverflow.com/questions/22062037/hcitool-lescan-shows-io-error对我不起作用。
BLE 是否可能以某种方式被关闭或阻止？是否有任何设置可以检查或启用此功能？
英特尔 NUC 版本：NUC11TNKv7
英特尔 NUC 操作系统：Ubuntu 20.04
蓝牙版本：5.1（无内置加密狗）
