Revision as of 20:27, 18 December 2019

Since 5.0-910, Dolphin has the ability to passthrough a Bluetooth adapter for emulated Wii software. This gives emulated Wii software full control of a Bluetooth adapter, which, provided a decent, working adapter, notably allows pairing Wii Remotes to Dolphin, third-party Wii Remote support, working Wii Remote audio and more accurate connectivity.

Limitations

  • The functionality and quality of the connections heavily depend on the quality of the adapter.
  • Even though most adapters work fine in passthrough mode, the only perfect adapter is the Wii's Bluetooth module (so far).
  • Save states can be used with some limitations.
  • Because Bluetooth Passthrough Mode skips Dolphin's emulated Bluetooth and Wii Remote code entirely, it is not possible to mix passthrough mode and emulated/real Wii Remote. This means that netplay, TAS input, input display, etc. cannot work.

Setting up

Linux

A udev rule has to be installed so Dolphin can use a Bluetooth adapter without having to get root privileges. 

SUBSYSTEM=="usb", ATTRS{idVendor}=="YOURVID", ATTRS{idProduct}=="YOURPID", TAG+="uaccess"

Dolphin should be able to automatically unload the USB Bluetooth kernel module (assuming you have permission to; you typically need to be in the plugdev group). If not, unload it with modprobe -r btusb.

Windows

WARNING: While a libusb driver is installed, other programs/devices will not be able to use your Bluetooth device. This can be easily reverted in Windows Device Manager and instructions are provided below.

Download and open Zadig as Administrator, then:

  1. In the "Options" menu in Zadig, make sure "List All Devices" is enabled.
  2. Look through the devices for the device to passthrough.
  3. On the right column, select "libusbk" or then click "Replace Driver". Select "Yes" to modify the system driver.

If you wish to return your Bluetooth back to normal, start "Device Manager" and locate "libusbK" devices in the list. Right click the device you wish to restore and uninstall device. Upon plugging it in next time, Windows will install the default Bluetooth driver and it will continue functioning per normal. NOTE: If you used the winUSB driver instead, it will be located under "Universal Serial Bus Devices." Same instructions apply otherwise.

If Dolphin is unable to use your Bluetooth device after doing this, it may not have the necessary hardware features. You can attempt to use the "winUSB" driver from zadig as a last ditch effort.

usbdk

As of 5.0-10617 usbdk is no longer supported.

Some users who wish to maintain use of their Bluetooth Device and use it in Dolphin without swapping drivers have opted to use usbdk. When Dolphin starts up, you will lose control of your Bluetooth Device and regain it when Dolphin is shutdown. While this cuts down on the work if you need to use your Bluetooth device across many controllers, usbdk has many bugs. The worst of which is that any ES_Launch will immediately crash freeze the game due to usbdk losing control of the Bluetooth.

macOS

There is currently no way to use this feature on versions newer than 10.9, because Apple removed the ability to unload the Bluetooth kernel module.

A potential solution would be to force the OS to ignore the adapter with a codeless .kext, but this hasn't been tried yet.

Android

This feature is not supported on Android.

Using passthrough mode in Dolphin

In Dolphin, open the Controller Configuration dialog, then select the "Passthrough a Bluetooth adapter" option in the Wii Remotes section.

While a game is running:

  • Wii Remotes can be synced and paired to Dolphin by using the Sync button.
  • All saved Wii Remote pairings can be reset by using the Reset button. This will also disconnect all currently connected Wii Remotes.

Advanced usage

Sync button hotkey

It is possible to use the "Press Sync Button" hotkey as an alternative to the buttons in the controller configuration dialog.

You will need to map "Press Sync Button" to a key or combination of keys. This can be done within Dolphin by left clicking on the "Hotkey Settings" tab under "Options" to bring up the appropriate configuration menu. You must then left click on the "Wii and Wii Remote" tab and left click on the box for "Press Sync Button" to map this hotkey.

"Press Sync Button" is designed to work just like the Wii's red sync button:

  • Pressing the hotkey will trigger a sync.
  • Holding the hotkey for 10 seconds will clear all saved pairings.

Forcing a specific adapter

If you need to use a specific adapter, instead of using the first Bluetooth adapter that is found, you can force Dolphin to use it by editing Dolphin's configuration file (Config/Dolphin.ini). In the BluetoothPassthrough section, set "VID" and "PID" to your adapter's vendor ID and product ID. These values should be converted from hex to decimal, for example a VID of "057E" should be inputted as "1406".

Troubleshooting

"Failed to open Bluetooth device: LIBUSB_ERROR_ACCESS"

This error means that Dolphin doesn't have permission to use the Bluetooth adapter.

If on Linux, make sure the udev rule is set up correctly.

"Failed to open Bluetooth device: LIBUSB_ERROR_NOT_SUPPORTED"

On Windows, this typically means that the libusb/WinUSB driver was not installed for the adapter.

"Failed to detach kernel driver for BT passthrough"

Dolphin tried to automatically unload the Bluetooth USB kernel module and failed to. Unload the module manually before starting a game to avoid this issue.

Wii Remotes do not stay paired after closing the game

This means that your adapter is likely broken and does not remember Wii Remote link keys properly. Use a different adapter to avoid this issue.

This may also happen if your SYSCONF is corrupted or if you changed to a Dolphin version which doesn't have BT passthrough. If your adapter is listed as working with pairing or if you're sure it supports pairings (by having checked the HCI command replies), you can try deleting Wii/shared2/sys/SYSCONF and Wii/btdinf.bak.

Black screen on boot

Games send a reset command to the Bluetooth adapter when they start and wait for it to be acknowledged. If you are getting a black screen for a long time (more than 10 seconds), your adapter may be stuck in a broken state and is unable to respond to any commands. Unplug the adapter and try again.

No usable adapter found

This can happen with some adapters. You'll need to force your adapter to be used.
