Android 蓝牙劫持可能吗？

Question

从 http://developer.android.com/guide/topics/wireless/bluetooth.html 读取,

The current Android Bluetooth API's require devices to be paired before an RFCOMM connection can be established. (Pairing is automatically performed when you initiate an encrypted connection with the Bluetooth APIs.)

然而，据我所知，蓝牙协议(protocol)允许.vcf (vCard)无需配对两个设备即可发送的文件。这就是 Bluejacking 的原因可能在索尼爱立信 k7** 系列、诺基亚 63** 系列等旧手机上。

为了编写 android bluejacking 应用程序，我希望能够从 Android 发送 vCard 文件，而无需先与设备配对。有谁知道这是否可能？

Answer 1

您可以让手机无限期被发现，这可能是 bluejackign 成为可能的起点:

EXTRA_DISCOVERABLE_DURATION Intent extra. The maximum duration an app can set is 3600 seconds, and a value of 0 means the device is always discoverable.
