Summary: Bluetooth connection is sporadic, quality is poor -
halts and stammers with
linux-firmware-network-20250917_1
Product: Drivers
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: Bluetooth
Assignee: linux-bluetooth@vger.kernel.org
Reporter: bob.hepple@gmail.com

Laptop is a Dell Latitude 3120 probably manufactured in 2021.
OS is voidlinux/x86_64/glibc:
Linux dosa 6.12.54_1 #1 SMP PREEMPT_DYNAMIC Mon Oct 20 18:07:19 UTC 2025 x86_64
GNU/Linux
Bluetooth Chip is an Intel AX201, lsusb gives:
Bus 001 Device 005: ID 8087:0026 Intel Corp. AX201 Bluetooth
I found that booting an old Mint USB stick worked fine so I thought to try an
older version of the firmware:
From dmesg I found that the firmware is /lib/firmware/intel/ibt-19-0-0.sfi and
ibt-0040-0041.ddc
The Mint 8 version of the firmware is 249-27.23
The VoidLinux version is 193-33.24 (ie 2024 and newer)
Get the 2023 firmware files:
cd /tmp
wget
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/intel/ibt-19-0-0.sfi?h=20231030
-O ibt-19-0-0.sfi.20231030.249-27.23
wget
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/intel/ibt-0040-0041.ddc?h=20231030
-O ibt-0040-0041.ddc.20231030.249-27.23
sudo cp /lib/firmware/intel/ibt-19-0-0.sfi
/lib/firmware/intel/ibt-19-0-0.sfi.193-33.24
sudo cp /lib/firmware/intel/ibt-0040-0041.ddc
/lib/firmware/intel/ibt-0040-0041.ddc.193-33.24
sudo cp ibt-19-0-0.sfi.20231030.249-27.23 /lib/firmware/intel/ibt-19-0-0.sfi
sudo cp ibt-0040-0041.ddc.20231030.249-27.23
/lib/firmware/intel/ibt-0040-0041.ddc
sudo reboot
bluetooth (& wifi) work perfectly with the older firmware - does the driver
need an update to catch up with the newer firmware?
