Default [Q] bluetooth ui problem

Hello

I am working on Android JB 4.2

I have ported SD8787 BT device and I now can activate it using BDT (bluedroid test tool)

but when I try to activate it using "settings"--> bluetooth I get the following message:

E/BluetoothAdapter( 2549): Bluetooth binder is null
E/DeviceListPreferenceFragment( 2549): Bluetooth is not supported on this device


can anyone assist on this issue?

Thank you
