swift - Apple 蓝牙 2009 ANSI 键盘的 ProductID

Question

我正在尝试在 Swift 中获取我连接的蓝牙设备的电池电量。在我的机器上，所有设备都被正确检测到。但是，未检测到通过蓝牙连接的 2009 Apple Wireless Bluetooth ANSI 键盘(很遗憾，我没有此键盘)。

在我的代码中，我使用了以下蓝牙产品 ID:

WIRELESS_KEYBOARD_2009_ANSI = 0x0239
WIRELESS_KEYBOARD_2009_ISO = 0x023A
WIRELESS_KEYBOARD_2009_JIS = 0x023B
WIRELESS_KEYBOARD_2011_ANSI = 0x0255
WIRELESS_KEYBOARD_2011_ISO = 0x0256
WIRELESS_KEYBOARD_2011_JIS = 0x0257
MAGIC_KEYBOARD = 0x0267
WIRELESS_ANSI = 0x022C
WIRELESS_ISO = 0x022D
WIRELESS_JIS = 0x022E

我很确定它是 0x0239，但看起来我错了。那么有没有人使用 2009 年的 Apple 蓝牙键盘并且知道该设备的产品 ID 是什么？

我正在使用 IOKit 并在“AppleBluetoothHIDKeyboard”条目中搜索。

要找到键盘，可以使用此处列出的资源管理器工具:http://mac.softpedia.com/get/System-Utilities/IORegistryExplorer.shtml

或者使用终端命令:ioreg -l | grep BatteryPercent

问候，萨沙

我有一个 2009 无线键盘 ( two batteries, dashboard button )。这是系统信息的输出:

Address:              00-25-BC-FB-2B-DB
Major Type:         Peripheral

Battery Level:      41%
Firmware Version:     0x0050
Vendor ID:          0x05AC
Product ID:         0x0239
Class of Device:      0x05 0x10 0x2540

看起来产品 ID 是 0x0239，如您所想。

这是 ioreg -i 的相关输出(没有行与 BatteryPercent 的 grep 匹配)
