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

Outputs from several other commands seem OK to me.

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

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
$ cat path 
\_SB_.PCI0.URT0.BLTH
$ cat status 
15
$ cat uevent 
MODALIAS=acpi:BCM2E7C:APPLE-UART-BLTH:
$ cat power/runtime_enabled 
disabled

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?
