Wiimote not detected dolphinbar

[capitalistspz]

I have a dolphin bar and a third party Wii mote.
The Wii mote works on my Wii U, it works in modes 1,2 and 3 on the dolphin bar,
but mode 4 isn't detected by dolphin.
However it works fine on the Wii U emulator (in mode 4)

When I used to use a direct Bluetooth connection, dolphin would detect it.

Help

Edit: The controller now works for about 2 minutes and then dolphin no longer detects it. The controller itself stays on and so does the Dolphin Bar

Is it an original wiimote or a third party?

His edit says it is a third-party.
