I have Bose Bluetooth speakers that with the dist kernel I can pause video playback with the button on the speaker however with the custom kernel I have configured I cannot pause playback but I can control the volume. Is there a module that I am missing in the custom config that the dist kernel is using to allow the bluetooth speaker to have the ability to pause video playback?

Perhaps rfcomm, but the easiest is to compare lsmod output from the two kernels. You can post it here, so other people can also help.

Best Regards,

I believe you are correct about rfcomm as that was a difference I had noticed in the lsmod outputs and the bluetooth wiki mentions it as well. I'm just not sure which kernel option enables that. I used make xconfig and searched for it however the options that search found were enabled.

My custom kernel lsmod output:

I don't know about xconfig, but in menuconfig it is / then type in something and it'll find everything containing it.

In your case it's Networking -> Bluetooth

Best Regards,
Georgi

p.s. you don't need all the bluetooth drivers. You have intel, bcm, mtk, rtl. Only one of them is your driver. It looks like intel is the only loaded wifi driver, so I guess you need bt_intel only.

Thanks for the help.

Both options that come up when I search RFCOMM in menuconfig are set to y

I'm lost at this point...

If you compare both outputs of lsmod you wil see:
Code:
bluetooth            1040384  28 btrtl,btmtk,btintel,btbcm,btusb
<=>
bluetooth             868352  44 btrtl,btmtk,btintel,btbcm,bnep,btusb,rfcomm

This means you also miss bnep (I am very unsure if you really need Bluetooth Network Encapsulation Protocol; but enabling it does not hurt).

Do you have both enabled ?
-> Networking support -> Bluetooth subsystem support -> Bluetooth Classic (BR/EDR) features -> RFCOMM protocol support
-> Networking support -> Bluetooth subsystem support -> Bluetooth Classic (BR/EDR) features -> RFCOMM protocol support -> RFCOMM TTY support

Maybe you will need also "Enable Microsoft extensions" ? Have you done a compare between your kernel .config and our dist-kernel (for BT) ?

I do have both of these enabled. I will enable bnep and see if that enables rfcomm for whatever reason.

I will try this after I enable bnep.

Thanks.

Just checked and bnep is enabled but I see that CONFIG_BT_HCIUART_BCSP was not enabled in my kernel so I am trying that now.

Quote:

CONFIG_BT_HCIUART_BCSP

Help text
BCSP (BlueCore Serial Protocol) is serial protocol for communication between Bluetooth device and host. This protocol is required for non USB Bluetooth devices based on CSR BlueCore chip, including PCMCIA and CF cards.

So enabling BCSP didn't make a difference.

Do you know the CONFIG_ symbol for the microsoft extensions?

Yes, I know it, but you dont need the name ... because you change any configuration only with "make menuconfig" (or other) and never edit .config
( https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_kernel_configuration#Never_edit_.config )
Just look into: Networking support -> Bluetooth subsystem support ---> and there it is :lol:

I never edit the .config directly I usually use nconfig or xconfig. The search function in nconfig uses the CONFIG_ symbol.

I am not seeing the Microsoft extensions option in any of the config menus.

Here is the diffconfig output

You've statically compiled in the drivers into the kernel.

What's the output of

Code:
dmesg | grep firmware

I've never heard of those. Is it something in the newer kernels (6.1 here) or are you sure you didn't mistype it?

EDIT: Sorry, I found it. CONFIG_BT_MSFTEXT It's not under devices, but directly under Bluetooth in Networking.

Best Regards,
Georgi

I am using only "make menuconfig" and when I go into: Networking support ---> Bluetooth subsystem support ---> (with kernel version 6.6.x) I get:

(you see I dont have it enabled; it is s clean new installation because I am running 6.9; this is only installed for checks)

If you go into the help of the last line "Enable Microsoft extensions" you see the name (CONFIG_BT_MSFTEXT) and it depends only on:

Depends on: NET [=y] && BT [=m]

So, if you dont have this option with 6.6. ... THEN something is very wrong with your .config ... In this case: Throw it away and do a completely new one with:

I am using kernel 6.6.30

So I checked make menuconfig again and the Microsoft Extensions option is enabled.

Yes, this helps a lot ... thank you.

What happens if you enable CONFIG_BT_HCIBTUSB with all protocols:
Code:
# CONFIG_BT_HCIBTUSB_BCM is not set               |   CONFIG_BT_HCIBTUSB_BCM=y
# CONFIG_BT_HCIBTUSB_MTK is not set               |   CONFIG_BT_HCIBTUSB_MTK=y
# CONFIG_BT_HCIBTUSB_RTL is not set               |   CONFIG_BT_HCIBTUSB_RTL=y

?

(I was sure it is a protocol problem and that's why I guessed microsoft extension, but of course it depends how your BT-boxes work internally, maybe it use one of these protocols)

Still volume and playback controls on my BT headset work. It should be something else. One thing I notice is I have uinput loaded, but I'm not sure if it has something to do with it.

Also sorry for the silly questions, but did you run make, then make modules_install? Also make install would run things like depmod -a and perhaps other stuff, so the full procedure might be better.

Is uinput bluetooth specific? Also what is the make menuconfig option for it?

I always rebuild the kernel according to the directions in the Build -- Manual build and installation section on the Kernel Upgrade wiki.
https://wiki.gentoo.org/wiki/Kernel/Upgrade
So make modules_prepare then make then emerge @module-rebuild then make modules_install and finally make install.

It was the uinput option!!! Thanks so much! I am removing other options and testing to verify that is the only requirement, I will report my findings.

Thanks again.

I don't know if uinput is necessary and it definitely is not bluetooth specific. Run make menuconfig is the ncurses interface for configuring kernel. In many ways it's superior to xconfig.

I've never heard heard of modules_prepare nor I've used it even once in the last 25 years.

However enabling rfcomm and modprobe not finding it as a module suggests you're missing something. Are you sure you're configuring the kernel you think you are or are you sure if you're running the kernel you configured?

What does uname -a say?

Georgi

Great catch !! ... yes, it is a great advantage if you have the appropriate hardware and can carry out tests yourself ... time to complete the wiki article ->
