Is there a command-line interface to list all Bluetooth devices in range on mac?
提问by Nick Sweeting
I want to list all in-range Bluetooth devices, ideally with hostnames, but MAC addresses would be sufficient. I need a command that performs an active scan so I can poll to see if my device is nearby, not one that lists previously paired devices.
我想列出所有范围内的蓝牙设备，最好使用主机名，但 MAC 地址就足够了。我需要一个执行主动扫描的命令，以便我可以轮询我的设备是否在附近，而不是列出以前配对的设备。
My use-case is detecting whether my Bluetooth headphones or iPhone are in range of my Mac, to trigger security setting changes (e.g. sudo timeout). I've done a fair bit of Googling, and the only things I seem to be able to find are iOS swift code examples. I would be happy with OS X Swift code examples, AppleScript, terminal utilities, or pointers to good docs.
我的用例是检测我的蓝牙耳机或 iPhone 是否在我的 Mac 范围内，以触发安全设置更改（例如 sudo 超时）。我已经做了相当多的谷歌搜索，我似乎唯一能找到的是 iOS swift 代码示例。我会对 OS X Swift 代码示例、AppleScript、终端实用程序或指向优秀文档的指针感到满意。
I've looked at these options so far:
到目前为止，我已经看过这些选项：
blued: prints a list of mac addresses but they don't seem to change when devices go in or out of range or connect, and they aren't matched up to hostnamesblueutil(brew install blueutil): only prints power state, not device namesbluetoothaudiod: no usable interface- This Objective-C code Create a Terminal-Based Bluetooth Monitor in XCode?: I get several errors when compiling so it's hard to test it
- Using AppleScript to read it out the
Bluetooth Explorer.appGUI - Using
dtraceto see howBluetooth Explorer.appcomputes the list: difficult last resort - The ProximityApp from this forum post: Doesn't have a command line interface, so I cant query it remotely. I can write a script that stores the state in a file to read later, but it only works for one device at a time.
blued: 打印一个 mac 地址列表，但当设备进入或超出范围或连接时它们似乎没有改变，并且它们与主机名不匹配blueutil(brew install blueutil): 只打印电源状态，不打印设备名称bluetoothaudiod: 没有可用的界面- 这个 Objective-C 代码在 XCode 中创建一个基于终端的蓝牙监视器？: 编译时出现几个错误，所以很难测试
- 使用 AppleScript 在
Bluetooth Explorer.appGUI 中读出它 - 使用
dtrace来看看如何Bluetooth Explorer.app计算列表：困难不得已而为之 - 此论坛帖子中的Proximity应用程序：没有命令行界面，因此我无法远程查询。我可以编写一个脚本，将状态存储在一个文件中以供稍后读取，但它一次只适用于一个设备。

In Terminal, the command :
在终端中，命令：
system_profiler SPBluetoothDataType
gives you all the details about Bluetooth, including devices paired, with their names, MAC address. Result is unfortunately a bit too much, but with sed or grep command, you should extract what you need.
为您提供有关蓝牙的所有详细信息，包括配对的设备及其名称、MAC 地址。不幸的是，结果有点太多了，但是使用 sed 或 grep 命令，您应该提取您需要的内容。
