you have to add mediatek/mt7668pr2h.bin to your initramfs to get this mysterious bluetooth chip to be detected and working at boot ❯ dmesg | grep hci0 [ 2.617531] Bluetooth: hci0: CHISR is 0 [ 3.278555] Bluetooth: hci0: Device setup in 645633 usecs [ 16.716477] Bluetooth: hci0: Firmware already downloaded [ 16.736003] Bluetooth: hci0: Device setup in 19573 usecs ❯ bluetoothctl Agent registered [bluetooth]# list Controller 28:3A:4D:E4:36:2A ps4-bt-intern [default] works for me on gentoo ps4pro 7216b

Nice. Would this work for 7215B as well?

Try these:- Extract with zcat initramfs.cpio.gz | cpio -idmv Make changes Repackage using find . | cpio -o -c -R root:root | gzip -9 > /folder/initramfs.cpio.gz

right bluetooth firmware for ps4pro 7216b users and maybe more

Great find. When free, I will make the initram with this packaged in and then share on my socials.

Hi there,

I'm trying to research into how to configure or compile a initramfs. Do I need to compile a brand new initramfs with this ".bin" file added or can I install it to one of the folders of the file system?

I'm reading that I can use dracut to compile an initramfs file, but figured I'd ask here as well since you've been successful at it already.

Thanks.

Try these:-

Extract with zcat initramfs.cpio.gz | cpio -idmv
Make changes
Repackage using find . | cpio -o -c -R root:root | gzip -9 > /folder/initramfs.cpio.gz

Thank you noob. I'll report back once I give this a try.

I tried compiling it. Didn't seem to work when I tried it.
Let me know if I did this right when you guys have time.

Zabovis What's the issue?

Right I should've included that. See screenshot below:

I created a custom kernel from the kernel source to turn on the bluetooth drivers. As you see from the terminal log... it failed to load that mediatek binary file. Just wondering if I compiled the intramfs incorrectly.

Perhaps I should try 5.3.18 kernel source instead...

My system specs:

PS4 Pro: CUH-7215B
5.15.15 (codedwrench) custom compiled to include bluetooth drivers
-Nobara 36
-Custom initramfs with included mediatek binary file

Zabovis i have no pro for testing. But i try this later for my wireless USB Adapter.
Maybe i see an issue.

Thank you.

My choice for WiFi is really bad. Ar9271 is very buggy in itself. Now i dont know which of These Special effects touches your issues too. We have a very frustrating Hobby...

To me, there's something innately satisfying about tinkering and trying to unlock a hardware's capability.
I'm a novice/intermediate to ps4linux but its the frustration followed by periods of success that can make the hobby enjoyable and fulfilling.

But back on topic, the PS4 Pro for Linux is kind of a hot topic because this is where Sony introduced new Bluetooth and Wi-Fi hardware IIRC. So it's been very difficult for many PS4 Pro users to get Bluetooth and Wi-Fi working properly.

I'm not sure which model you're testing, but my PS4 Pro is a CUH-7215B model.
The CUH-7215B and CUH-7216B models may have the same Bluetooth hardware but I'm not sure how to verify that.

Zabovis i am on aeiola. With a little luck i can Test on slim too soon. A cheap pro lower than 9.00 would be nice.

Gotcha, ok yeah I'm on Belize. Is your slim model a Belize Chip? You might be able to find a PS4 Pro bundle with a lower firmware than 9.00, it may or may not be a little expensive.
