Strange bluetooth thing my computer does while it's booting

I'm using 4.2 kernel but it has been happening since the installation. (4.0.6)

I have this thing: https://bbs.archlinux.org/viewtopic.php?id=176121
My computer can scan, can TRY to pair, but it won't.

BTW my laptop's keyboard interracts with hardware; so when BT is on, there is a white light and when it is of, there is a orange light. It starts orange, then it becomes white, and then orange again. Maybe it's nothing and rfkill unblock solves it, i dunno. After I do rfkill unblock, light becomes white.

Maybe this is the problem:

Important part:

         Starting Network Manager...
[  OK  ] Started D-Bus System Message Bus.
         Starting RFKill-Block bluetooth...

...

[  OK  ] Created slice system-systemd\x2drfkill.slice.
         Starting Load/Save RF Kill Switch Status of rfkill0.
[  OK  ] Reached target Bluetooth.
[  OK  ] Stopped target Bluetooth.
[  OK  ] Stopped Load/Save RF Kill Switch Status of rfkill0.
[  OK  ] Started Network Manager.
[  OK  ] Reached target Network.

Sorry for bad English

Re: Strange bluetooth thing my computer does while it's booting

What is the output of journalctl -b -u bluetooth   ?

Okay, let's try dmesg | grep Bluetooth

Re: Strange bluetooth thing my computer does while it's booting

Yeah, based upon what I read in the other thread, and the output of that dmesg command, it looks like the kernel is not finding a driver for your card.
The next step should be where the kernel instantiates hci0.  When you entered bluetoothctl, I'll bet it did not print out a MAC address of your controller.  It would look like you could not type anything.

Verify that you did install https://aur.archlinux.org/packages/rtbth-dkms/.

Edit:  And this is not a systemd problem.

After rfkill, I can type. Also, rtbth is installed.
