Wiimote with Dolphinbar not working

[Heldenkrieger01]

Hello

I've got a new DolphinBar with the newest firmware and a Wiimote. I can sync them without any problem.
But as soon as I start any game, on the top left it shows "Wiimote 1 disconnected". The connection guides do not help.
I got Dolphin 5.0-6842.
There are no other Bluetooth-USB-sticks connected. Mode 1 (Mouse) of the DolphinBar works flawlessly.

Thanks for your help,
