Bluetooth connection issue with 8bitdo SN30 Pro contollers - Linux Mint Forums
forums.linuxmint.com

I posted this on the Linux mint forums a while ago, but no traffic on the post and it’s driving me crazy.

Problem: I can connect the controllers just fine via Bluetooth, but yuzu and dolphin don’t recognize them unless I’ve deleted them from blueman and freshly re-paired them. More details abd system info in the forum post, but this is the gist. Does anybody have any insight? It would be greatly appreciated. Thanks.

    Try running bluetoothctl from the commandline and playing around with it. This article is for Gentoo but you can go through the manual steps in “Device pairing” and maybe you’ll be able to identify the issue.

    Looking at bluetooth logs could also be useful. If the service is called bluetooth on Mint, try running:

    journalctl -u bluetooth

    My input isn’t going to be very useful but as a point of data, I’ve never had trouble with my 8bitdo controllers and Linux.
    Sometimes they don’t pair right away on the Switch, but Linux has been fine.
    Now I’m trying to remember which controller I used to test Yuzu…

    Weird as it is, I’ve heard launching games through Steam Big Picture mode with the controller connected can help but that might just be more a key mapping thing than anything else.

        A phone app?! Why didn’t I think to look for that. I’ll give that a look as well. Man I’m glad this community is full of troubleshooters.

    Try to mark the devices as trusted in blueman and see if it helps.

      Already did that to no avail. It seems like no matter what I do, this is what I’m doomed to. I’ll have to check out the BIOS/firmware for the controllers like the other person suggested.

    Not a Linux user but I had a lot of problems with the sn30 pro plus connecting to bluetooth when I first got it. The issue was something in the controller bios. It’d cause my entire system to spaz out. I had to roll back to the first version to fix it. So maybe try messing around with bios versions if you can to see if that fixes it.

      This is certainly an angle worth checking out. Is it easy enough to roll back the firmware?

        Very, but you’ll need a windows environment to do it. They only have windows or mac updaters. After that, it’s just plugging it in and picking the version. Looks like there’s only 2 updates, but it’s still worth a shot.

          Good to know. My PC is a dual boot with Windows 11, so no problems there. Thank you for the advice, I’ll be sure to update after I give it a shot.
