For the bad case, they're running an old kernel with new firmware. Theoretically it could be a kernel issue. 1. Please ask them to test the latest kernel with the latest firmware. 2. Given this is the 6.8 HWE kernel and Noble has newer firmware, the next step is to test the firmware from Noble. Please ask them to: - Backup /lib/firmware/mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin.zst - Download [1] and compress it: zstd -19 BT_RAM_CODE_MT7922_1_1_hdr.bin - Copy the new firmware: cp BT_RAM_CODE_MT7922_1_1_hdr.bin.zst /lib/firmware/mediatek/ - Reboot - Verify that the log shows: Bluetooth: hci0: HW/SW Version: 0x008a008a, Build Time: 20240219103618 - Rerun the test - Restore the backed up firmware [1] wget -O BT_RAM_CODE_MT7922_1_1_hdr.bin https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux- firmware/plain/mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin?h=noble ** Changed in: linux-firmware (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2098088 Title: bluetooth functionality for mediatek wifi/BT module MT7921AU does not work with latest firmware package on x86_64 platform To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2098088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
