如何检查我的蓝牙模块是否支持 Linux 中的 BLE 功能

Question

我想知道这一点，因为我有一些 BLE 设备，想检查一下我是否可以使用我自己的桌面蓝牙模块来解决这个问题。

Answer 1

通过 apt-get 安装 bluez 和 bluez-utils。然后使用 hciconfig

检查是否检测到 ble 设备

Answer 2

如果安装了 hciconfig 尝试使用 sudo hciconfig hci0 lestates

获取 LE 支持的状态

这应该显示可能的 LE 特定状态，如下所示

        YES Non-connectable Advertising State
        YES Scannable Advertising State
        YES Connectable Advertising State
        YES Directed Advertising State
        YES Passive Scanning State
        YES Active Scanning State
        YES Initiating State/Connection State in Master Role
