Since {{revision|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.
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.


== Limitations ==
== Limitations ==
* 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.
* The functionality and stability of the connection heavily depends on the compatibility of the Bluetooth adapter used.
* The functionality and stability of the connection heavily depends on the compatibility of the Bluetooth adapter used.
* Even though most Bluetooth adapters can be used in passthrough mode, perfect compatibility is only guaranteed with the Bluetooth modules from Wii consoles.
* Even though most Bluetooth adapters can be used in passthrough mode, perfect compatibility is only guaranteed with the Bluetooth modules from Wii consoles.
* When using Bluetooth Passthrough mode, the emulated software directly communicates with the Bluetooth adapter, so it's not possible to mix passthrough mode with emulated Wii Remotes and some Dolphin features like Netplay, TAS input, input display, among others, won't be available.
* 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.
* Save states made in Bluetooth Passthrough mode can't be loaded on "Emulate a BT Adapter" mode, nor vice-versa.

* Wii Remote connection state dictates whether save states made in Bluetooth Passthrough mode will work or not:
