Bluetooth Passthrough - No Detection

[Saritos]

Hello, I've been trying to get my Wiimote to work through Bluetooth Passthrough but it doesn't seem to pick it up.

The Wiimote has MotionPlus inside of it, when it's picked up through my normal bluetooth it doesn't seem to say that it's a -TR model. (To my knowledge, the -TR models are more problematic.) It seems to be a standard black Wii Remote Plus.
My Bluetooth Adapter is an onboard one. For reference, the motherboard is a "MSI X99A XPOWER GAMING TITANIUM." The adapter seems to specifically be an "Intel Dual Band Wireless-AC 8260" and it is listed as "Intel® Wireless Bluetooth®" in Zadig.

The reason I am trying to use Bluetooth Passthrough is for minimal desync, as when I use my normal Bluetooth and Dolphin's regular emulated bluetooth, I tend to look control whenever the Wiimote rumbles.

I've followed the steps on the Bluetooth Passthrough tutorial page.
using the steps listed for Windows. I am using Windows 7 64-bit Professional, and I've installed the latest libusbK version. That being "UsbDk_1.0.19_x64.msi" which when in Zadig seems to be listed as "libusbK (v3.0.7.0)."

Using the latest build of Dolphin (5.0-9178), and enabling passthrough yields no result however. I can boot up the game, and when I try to sync my controller...nothing. It simply doesn't detect it. Occasionally I will hear the sound of a USB being unplugged when I try and boot up a game, rather than being plugged in. And when I turn the game off, the sound of a USB device being plugged in will play. Not sure if it relates to the problem of the controller not being detected. The controller only seems to work through the standard bluetooth emulation, but as stated previously there is occasional desync. 


I've tried looking through other threads with similar problems, but none so far seem to be tackling these specific issues. Anyway I can fix this?

It seems as though the libusbK has installed properly:

And here are my current controller settings:

Install either UsbDk or use Zadig, don't do both. In case UsbDk works properly (that's hit or miss in most cases), Dolphin should automatically take control of the adapter when you start emulation (that's the device unplugged sound you're hearing) and should automatically give its control back to Windows once emulation stops or you close Dolphin (that's the device plugged in sound you're hearing).

In case you want to go Zadig route, choose WinUSB instead of libusbK or libusb-win32 when replacing the driver, then run Dolphin and BT passthrough should work fine (at least it worked fine that way with the Intel Wireless-AC 9260 from my laptop, which is very similar to your 8260)...

You said the games actually boot up while in passtrough mode, so that's a sign that Dolphin detected your BT adapter and could get exclusive access to it (otherwise the games wouldn't even boot). So, how are you pairing the controllers? While a Wii game is running, you should press the red sync button next to the batteries enclosure (syncing with 1+2 won't work for this) and shortly after the Wiimote LEDs start blinking you should click the sync button in Dolphin Controller Settings...

Ah, thank you.

Installing UsbDK's libraries by themselves without touching the bluetooth drivers seems to yield no results. The controller plugging in and out sounds still occur, but Dolphin does not read the controller.

Using the Zadig route, am I supposed to replace the Bluetooth drivers with WinUSB? I've tried twice, and the first time it began to say "LIBUSB_ERROR_NOT_FOUND."
I know using both was advised against, but for the sake of seeing if something would click, I installed the libraries and tried replacing the bluetooth drivers with WinUSB again. Still nothing.
The next attempt was uninstalling libusbk libraries, and trying only with WinUSB again. This time the game would boot, yet still Dolphin wouldn't detect my controller. The device plugging in/out sounds also stopped occurring with this attempt, presumably from the lack of libusb but I'm not sure if they should still be occurring regardless of libusb being there or not.

Then I'm afraid your BT Adapter is incompatible with BT Passthrough (it's only guaranteed to work flawlessly with a real Wii BT adapter modded to plug into an USB port). This feature works by directly exposing your BT Adapter to the emulated game, so the communication is entirely handled by the game itself, Dolphin has no involvement in that other than sending an event to tell the game the sync button was pressed. On a real Wii, there's only a single BT Adapter model, so all Wii games assume they're talking to that specific adapter, while in Dolphin you can "expose" any BT adapter you have (but compatibility isn't guaranteed).

And let me enlighten you about the operating modes, you still seem a little confused. When you go UsbDk route, you're actually installing a filter to all USB devices in your system, so programs can request exclusive access to them without needing to fiddle with the device drivers. When it works (and it seems it worked on your computer) it's the ideal scenario for Dolphin, since it can automatically gain exclusive access to the BT Adapter when you run a Wii game in BT Passthrough mode and can automatically give control back to the OS once emulation stops. On this scenario you can still use Bluetooth functions normally when you're not using Dolphin or not running Wii games in BT Passthrough mode, and that's also why you hear device unplugged/plugged songs when you start Wii games with UsbDk...

When you go Zadig route, you're actually replacing the driver of your BT Adapter with WinUSB/libusbK/whatever you choose in Zadig. That means the BT Adapter isn't accessible anymore by Windows BT Stack and it's permanently available to programs for direct access through WinUSB/libusbK/whatever (by permanent I mean until you uninstall the driver Zadig created). Bluetooth functions won't be available at all while the Zadig driver is installed and only libusb-enabled apps (like Dolphin, SCP Toolkit, DS4Windows, etc) will have access to the BT adapter, that's also why you don't hear any device unplugged/plugged songs with Zadig...

And on a final note, if you've successfully booted Wii games in Dolphin with BT Passthrough selected, then your BT adapter is definitely being picked up correctly and the game is able to communicate with it (otherwise all you would get would be a black screen or Dolphin refusing to boot with an error message). If you can't pair your controllers while the game is running then your specific BT Adapter isn't compatible with BT Passthrough and your only choice is trying a different adapter...
