Android的蓝牙LE MAC地址随机化 [英] Android Bluetooth LE MAC Address Randomization
问题描述
蓝牙LE引入随机广告设备的蓝牙设备地址的能力。玩弄Android中API21的BluetoothLeAdvertiser类，我缺少启用此功能的方法。我的测试设备的设备地址总是一样的（没有任何随机）。
Bluetooth LE introduced the capability to randomize the Bluetooth device address of an advertising device. Playing around with the BluetoothLeAdvertiser class in Android API21, I am missing the method to enable this feature. The device address of my test device is always the same (no randomization whatsoever).
这怎么可能使用蓝牙LE设备地址随机化的Android？
How is it possible to use Bluetooth LE device address randomization in Android?
谢谢，
马丁
推荐答案
您还别说该博客说：
在一般情况下，这些随机的，专用MAC地址变化，按照该制造商在他们的产品的固件实现的计时器。因此，他们知道MAC地址究竟是如何经常变化。
In general, those random, private MAC addresses change according to a timer that the manufacturer implements in their product’s firmware. As such, they know exactly how often the MAC address will change.
因此，这似乎是一个内置的功能，似乎超越了应用程序员的控制。当然，这是为了保护应用程序用户的隐私。我已经注意到了随机重启只有我的智能手机后，我quess它可能会从设备而异。
So this seems to be a build-in feature and seems beyond control of the application programmer. Of course, this is meant to protect the privacy of the application user. I have noticed the randomization only after rebooting my smartphone, i quess it might vary from device to device.
