Bluetooth passthrough with Arch Linux?

[Youngsie97]

Hi there, just curious to see if anybody has had any success getting Bluetooth pass through working on Arch Linux?

I've done a bit of googling but came up empty so decided to post here instead.

So first up i'm using the Kinvio BTD 400 adapter I've had it working on Ubuntu and Windows but i'm not having any luck with arch .

I'm using 4.12.4-1-ARCH linux

I've set both the udev rule and dolphin.ini as follows.

Udev
SUBSYSTEM=="usb", ATTRS{idVendor}=="0A5C", ATTRS{idProduct}=="21E8", TAG+="uaccess" (I've also tried with decimal values)

Dolphin.ini
[BluetoothPassthrough]
Enabled = True
VID = 2652
PID = 8680

Input of any kind would be much appreciated thanks for your time

What's the error Dolphin gives you? ERROR_ACCESS? If so, that means the udev rule is not actually getting loaded so Dolphin can't access the adapter. Have you checked the Arch wiki for the proper location?

I haven't actually but putting the gamecube udev rule in /etc/udev/rules.d seems to work, i'm wondering if i perhaps have the file named wrong? i went for 52-bluetooth.rules?

[leolam]

That should be fine.

scratch this, it seems even without the rule file the gc adapter works now, so it is possible that the rules aren't being loaded.

I've checked the wiki and /etc/udev/rules.d is indeed the place the files should reside, so now i'm really stumped as to why it isn't working. I've tried udev reload udev trigger and even rebooting the system to no Avail. Thanks for the suggestion  anyhow

[leolam]

Rebooting the system should be unnecessary (after all this isn't Windows ), just make sure to unplug/replug after changing rules.

Anyway, have you made sure the issue is actually related to permissions? What error does Dolphin show?

Failed to open Bluetooth device: LIBUSB_ERROR_ACCESS(related to udev) then no Bluetooth device found. Running dolphin as sudo removes the first error as it can obviously access stuff but then it can't find my Bluetooth adaptor as i have to force it in Dolphin.ini and i have no idea where Dolphin would store it's configs when run as sudo .

So it almost certainly looks like permission issues but i'm new enough to Linux that i don't know where in the chain i need to fix it.

Not the best way by far and i would love to fix the issue properly but for the mean time i've found a work around is to run sudo dolphin-emu -u folder then just edit the ini in that folder bluetooth passthrough is now working flawlessly,

for now i've got an alias Dolphin for sudo dolphin-emu -u dolphinconfig

this is obviously not the best way as it is the inpropper way to do things but allows me to play Kirby epic yarn

If anyone else is running into this problem, I figured out how to get it to work. I put the udev rule in /usr/lib/udev/rules.d/51-usb-device.rules and I was able to use the USB passthrough feature!
