[BluetoothPassthrough] Wiimotes disconnect in certain games when paired 2 remotes

[pwndxD]

Hi,

I have been experience this issue for a few months now with all the dolphin builds I've tested.
I am using Bluetooth passthrough with a Intel Dual Band Wireless-AC 7260 on Windows 10 (also tested with same result on Ubuntu)
The adapter works flawlessly for all the games I have with one controller, but in some games like Mario Tennis, Most shooter on rails (HOTD 2,3, Resident Evil, Just Dance etc) when paired with 2 controllers, at some point they simply disconnect. For example for Mario Tennis it disconnects after selecting all the options and the screen is blank and right before the the match starts they just unpair and start blinking and only work if I leave the game.

I noticed I always have a "Failed to transfer to or from to the Bluetooth Adapter. It may not be compatible with passthrough mode" message and in the logs I have the following " core\ios\usb\bluetooth\btreal.cpp:661 E[IOS_WIIMOTE]: libusb transfer failed, status: 0x03".

I know the message is explicit and indicates that the issue might be with the adapter but what I find very weird is that all games work with only one controller even the ones that require motion plus (Skyward sword, golden eye etc).
Also other games like Mario Kart Wii and Wii Play Motion work with 2 controllers and the issue above does not happen.

Can you help please?

Thanks

There's nothing you can do, your adapter simply doesn't play nice with multiple Wii Remotes. Different games also communicate with the Wiimotes in different ways, that's why you don't experience the issue in some games. Flawless compatibility in Dolphin's Bluetooth Passthrough mode is guaranteed only when using a real Wii Bluetooth Module modded to USB...

Thank you guys.
I guess only thing left is to give the wii bluetooth module a shot. Lets see if I am any good at soldering.
Cheers.
