Dear NXP,

   I am working on Toradex apalis imx6q with Android Nougat. When we try remove the paired device(bu clicking unpair), unpair was done properly. But, still music playing on bluetooth headsets.

Steps::
      1.Go BT and connect your phone.
      2.start play music.
      3.go to BT(headset/phone) and unpair the device.

Observation::
      still song/error is playing in the bluetooth headset.

Hi jimmychan, 

Thank you for your reply. The issues in bluetooth stack. I want to disconnect the headset after unpair.

I think this is an application layer issue. You better to consult the company of your BLE chip. Your application may call the BLE stack. In the stack events, there should have a case for "disconnect" status. So , when BLE is disconnected, you can stop to play the music.
