Bluetooth devices not being loaded #45
Comments
Does lsusb list your bluetooth device? And nevermind grep, read all of dmesg. Maybe put it on pastebin. |
$lsusb This is the dmesg output: https://pastebin.com/uRPGdMwc Thanks for taking a look. |
This is why I am fearing the worst. Everything looks fine in my eyes. As if it should work, but it doesn't so it might be a hardware issue. I am going to get windows running in a virtual machine to see if it will get the the bluetooth going that way. |
" 0b05:1872 ASUSTek Computer, Inc. " is some LED controller. It looks like you don't have a Bluetooth adapter at all. Is it disabled in the BIOS? Also, I see you're not using the rtw88 driver. I'm not sure why you're posting here? |
Or maybe you were using rtw88 but then you updated the kernel or something and forgot to recompile? |
I did update my kernel. Then went to recompile and didn't find the original git repo that I used to install the drivers. I found this one which includes my device so I decided to clone this repo, build and install. I did however try to reinstall the repo version I originally used but no luck. Can't remember the name of the repo but the link I had for it gives me a 404 in github. That makes sense, funny that the RGB lights have their own drivers and are working but bluetooth/wifi is this whole ordeal. I am really thankful that lwfinger put together these driver repos. So, how would I go about getting a clean slate to clone/build/install this driver? I tried sudo rmod rtl8822be and in the rtw88 repo make/install but maybe that is not enough? |
Why do you feel you need a clean slate? Doing "git pull; make; sudo make install" while in the download directory (rtw88>) will reinstall this driver. Without a BT interface showing in the lsusb listing, you will NEVER get BlueTooth. This rtw88 repo is ONLY for wifi. The kernel drivers btusb and btrtl in directory drivers/bluetooth are used to drive the Realtek BT devices. |
I felt the need for that since I thought no device visible = driver not loaded properly. Does lsusb just checks the hardware component directly? Ah, I was going to look for the name of the older driver I had but I deleted it because I thought this one had worked (since I had wifi). So any ideas or recommendations? Am I condemned to using windows until the end of days or do I have to buy a new computer to keep using Linux? I seriously don't know what to do, I haven't had time to run the VM Windows experiment yet but will be doing that tomorrow. Will actually install in a separate partition since that way windows can access hardware directly. THANK YOU PROPRIETARY DRIVER VENDORS. THIS IS TOTALLY GREAT. YOU ARE ESSENTIALLY KEEPING OWNERSHIP OF THE HARDWARE I PAID FOR. WELL PLAYED. |
The image of Linus giving them the mighty finger comes to mind, they have it well deserved. sigh |
Did you check the BIOS? Some laptops let you disable the Bluetooth there and then the operating system shouldn't see it at all. To easily check if it's a distro problem somehow (too old kernel? I don't know) you can put the live Opensuse Tumbleweed image on a USB stick and boot that. It has a recent kernel with rtw88 included. |
Yeah, the bluetooth controller is enabled in the BIOS settings. I will try the Opensuse Tumbleweed image. Hopefully my motherboard is not broken. I can live without bluetooth I think, but it would still be a hard blow. |
I was seeing a comment about how it is unlikely the bluetooth module is broken since the wifi is in the same card as the bluetooth. Since wifi is working the card is probably good. I don't know enough about how the actual card hardware is constructed but I hope they are correct. We'll see. |
Yes, lsusb interrogates the hardware without use of any driver. Its scan method is exactly the one used by the kernel to detect if a particular device is available. To reiterate, if no BT device in the lsusb scan, no BT driver will be loaded. |
I booted into an openSUSE live usb. The bluetooth settings said 'no bluetooth device detected', lsusb gave the same output as above with no bluetooth in sight. I gotta just accept reality for what it is and declare this bluetooth component dead. Closing this issue, thank you guys for taking a look and helping out. |
Aha! So, took apart my computer took out the battery in the motherboard and reset the CMOS. Bluetooth is back up. For anyone facing this issue this solved it for me: https://rog.asus.com/forum/showthread.php?108642-Bluetooth-suddenly-stopped-working Again, I really appreciate the help and the awesome driver to support Linux computing. You guys are awesome. |
Hello,
Bluetooth on my debian machine stopped working a couple of days ago. I have been trying to find the root of the problem but haven't been able to. So now I resort to ask for help.
My motherboard is
Asus ROG Strix Z370-I Gaming Mini ITX LGA1151 Motherboard
which has the Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter. This is the device that provides bluetooth connection as well.

I might have to black list some of those above, but they look the same as someone who had their bluetooth working properly, so I don't know if the issue is here.
I've been hit with issues that I have solved on my own before with my general knowledge of how this driver works, but this issue in particular got me fearing two things:
- Either there is much more I still don't understand about the inner workings of this driver.
- Or my physical bluetooth card is damaged and this is a hardware issue. (I prefer to be an idiot that doesn't know how this system works rather than my motherboard having a component fried)
Anyway, please help shed some light into what might be causing this issue. I would really appreciate it.
