我想使用蓝牙SPP在它进行交流。在一些Android手机，最高人民检察院的资料不会被激活。我面临着最高人民检察院未激活，因此该连接无法通过蓝牙技术建立在应用程序中的问题，当我开始了一个应用程序，它是3G热点，我想激活最高人民检察院和我能够连接通过蓝牙在我的应用程序。

I am trying to use Bluetooth SPP to communicate over it. In some Android phones, SPP profile is not activated. I faced the problem in the application that SPP was not activated and so the connection could not be established over bluetooth and when I started another app that is 3g hotspot which I think activates SPP and I was able to connect over bluetooth in my app.

那么，我们如何才能真正激活蓝牙的Andr​​oid设备SPP的个人资料？而完成所有的Andr​​oid设备具有最高人民检察院的个人资料？

So, how can we actually activate SPP profile of bluetooth in Android devices? And does all the android devices has SPP profile?
