在Android中激活蓝牙SPP? [英] Activate Bluetooth SPP in Android?

问题描述

我正在尝试使用蓝牙 SPP 进行通信.在某些 Android 手机中，SPP 配置文件未激活.我在应用程序中遇到了 SPP 未激活的问题，因此无法通过蓝牙建立连接，当我启动另一个应用程序是 3g 热点时，我认为它激活了 SPP，并且我能够在我的应用程序中通过蓝牙连接.

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 Android 设备中蓝牙的 SPP 配置文件?是否所有的安卓设备都有 SPP 配置文件?

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