[SOLVED] Gimx Bluetooth Not Working (PS4)

[MicroDog]

Hello there. I'm on Linux Mint 21.3 and I've been using GIMX via bluetooth on the PS3 for some time now and it's working great, no issues whatsoever. However I can't get it to work via bluetooth on the PS4, I always get this error:

Code: Select all

Unknown Management opcode 7 (index 0)
failed to initialize bluetooth device
[01;31mError: [0mfailed to initialize the dualshock 4 emulation.

I did follow the instructions on the wiki to set up everything but no luck. Any ideas on what I could do to fix that?

Was the ps4 controller off during connection?

I tried with the controller on and off and it didn't work. But I'm not sure what I'm supposed to do with the teensy after pairing...

I tried setting up the teensy with the EMUPS4 firmware available on this release since I'm also using GIMX 8.0:

https://github.com/matlo/GIMX-firmwares ... s/tag/v8.0

But if I use that firmware then I can't get pass the 'plug the teensy' prompt, it seems like GIMX just doesn't recognize the teensy with that firmware.

So I set up the teensy with this firmware:

http://gimx.fr/download/EMUPS4PAIRING.7z

Which does let me complete the pairing process but then when I try to start GIMX I get that error on my first post.

What teensy board are you using?

[MicroDog]

I'm using a teensy 2.0.

Also, when I start GIMX with the output set to Bluetooth/PS4 it says 'Bluetooth service has to be stopped. Proceed?' I click on yes and then I get that error on my first post. It doesn't ask me that if I choose Bluetooth/PS3 though and it works just fine on the PS3.

I found this thread about your issue with a google search

Hey, sorry for the late reply. That thread linked pointed me in the right direction, thank you.

The problem was with the bluetoothd binary. I just had to rename it, delete gimx config files, redo the pairing and then it worked! Though DS4 inputs weren't recognized properly but I found a workaround in this thread.

Well done. Glad i could help you solve it
