Bluetooth Passthrough: Difference between revisions

Since {{revision|5.0-910}}, Dolphin has the ability to passthrough a Bluetooth adapter for emulated Wii software. This is a powerful option that allows for perfect Wii Remote behaviors on Dolphin, given a powerful enough Bluetooth adapter. Unlike standard Bluetooth emulation, Bluetooth Passthrough supports pairing third party Wii Remotes, Wii Remote audio, and can more accurately communicate fine motions. However, because Bluetooth Passthrough gives the Bluetooth adapter directly to the emulated software, there are heaps of limitations that make it only worthwhile for certain situations.

* Requires a specialized driver on Windows, and on Linux requires a udev rule. The Operating System will not be able to access the Bluetooth adapter while it is in use.

* Many features do not work. Netplay, input recordings will be limited. The Wii Remote may disconnect if Dolphin is running too fast or too slow. If the Bluetooth is disconnected from your computer, Dolphin may crash.

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 [http://zadig.akeo.ie/ Zadig] as Administrator, then:

If you wish to return your Bluetooth drivers back to normal, start "Device Manager" and locate "libusbK" devices in the list. Right-click the device you wish to restore and select 'Uninstall Device'. Upon plugging it in next time, Windows will install the default Bluetooth driver and it will resume normal functions. 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.

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 shuts down. While this cuts down on the work 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.
