    Description

      My application connects with a bluetooth device and activate the notifications for 5 sensor values. Working well on Linux.

      Under Android it's not working. It's possible to connect with the device but when I enable the notifications, nothing happen.
      Some debug outputs can confirm, that I write 0x0100 to the descriptor but I never receive any notification a value has changed. So obviously the notifications are not working on android.

      Edit//
      I found one working combination: The S4 Mini with Android 4.4.2 and in Qt using the API Level 19. That's all.
      A higher API Level for the S4 mini is not working and for the S6 with Android 6 nothing works. No API level 19, 22 or 23...
      I also attached some logs

      Edit2// Tested it with a Nexus 5 of a friend with API Level 23 - same error.
