title: Activate Bluetooth SPP in Android?
body: <p>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.</p>
  
  <p>So, how can we actually activate SPP profile of bluetooth in Android devices? And does all the android devices has SPP profile?</p>
