[Interest] Android bluetooth in a thread

[maitai]

Hello,

Another question about QBluetooth, this time on Android:

If I run a bluetooth "client" class in a thread, discovery fails and I 
have this weird message in the console:

QObject::connect: Cannot queue arguments of type 'QBluetoothServiceInfo'
(Make sure 'QBluetoothServiceInfo' is registered using 
qRegisterMetaType().)

If I run the exact same class in the main thread, no such message and 
everything works OK.

I know that on Mac OS bluetooth must be run in the main thread. Is it 
the same for Android? What about other OS (Linux, Windows, iOS) ?

Thanks
Philippe.
