Not detecting Bluetooth host controller on Macbook8,1+Linux 5.15
muojp opened this issue · comments
Hello. Thank you for maintaining a great project.
I started to give a try on MacBook+Linux configuration a couple of week ago but still having no luck for Bluetooth HCI communication yet (Wi-Fi works perfectly).
- Linux kernel: 5.15.0-56-generic (Ubuntu 22.04.1)
- Also tested on 5.4.0-26-generic (Ubuntu 20.04) but resulting in the same situation
- Hardware: MacBook8,1 (Retina, 12-inch, Early 2015)
- Broadcom's radio chipset seems a bit different from supported ones? (detailed below)
No internal Bluetooth dongle is detected after running ./install.bluetooth.sh & rebooting (kernel module is installed and activated according to the output of modinfo command pasted below).
$ sudo bluetoothctl
Agent registered
[bluetooth]#
^D
$ sudo bluetoothctl list
(no output)
$ sudo hciconfig -a
(no output)
$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
$
According to the dmesg output (pasted below), Linux does detect ttyS4 as a serial interface but not accessible once the OS is fully booted.
$ ls /dev/ttyS4
ls: cannot access '/dev/ttyS4': No such file or directory
I checked a hardware report on macOS 11.7 and compared against https://bugzilla.kernel.org/show_bug.cgi?id=110901#c32 .
I found the Broadcom's chipset seems slightly different (4350 vs 4350C1). It might be because I'm using a MacBook purchased in Japan (it's a common case for device manufactures to distribute different hardware variants among countries to meet radio-wave regulations).
Bluetooth Low Energy Supported: Yes

Below is a result of dmesg with some grep-ing. I think it's weird that there is no hci0 related outputs.

Any hints/comments are welcomed.
Here's some more information I found in /sys/devices/.
In /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:17/BCM2E7C:00:
$ ls
adr hid modalias path power status subsystem uevent uid

It means the device itself is recognized by the system as BCM2E7C which is listed in hci_uart.ko's aliases, but powered off by some reasons, right?
I have the same issue on Macbook 8,1 running Ubuntu 22.04.2 LTS
