Bluetooth RT3592 can't find any device


I have problem with my bluetooth. I have:
Notebook: Probook 4330s XX977EA
OS: Linux peto-nb 4.6.4-1-ARCH #1 SMP PREEMPT Mon Jul 11 19:12:32 CEST 2016 x86_64 GNU/Linux
Bluetooth module:
Code:
# lspci -k
...
24:00.0 Network controller: Ralink corp. RT3592 Wireless 802.11abgn 2T/2R PCIe
	Subsystem: Hewlett-Packard Company Device 1638
	Kernel driver in use: rt2800pci
	Kernel modules: rt2800pci
...
I have proceeded by this wiki page https://wiki.archlinux.org/index.php/bluetooth, so I installed bluez and bluez-utils and tried to discover my phone (it is discoverable, I checked it by another one):
Code:
root /home/peto # bluetoothctl
[NEW] Controller 68:A3:C4:0A:2B:12 peto-nb [default]
[bluetooth]# power on
[CHG] Controller 68:A3:C4:0A:2B:12 Class: 0x00010c
Changing power on succeeded
[CHG] Controller 68:A3:C4:0A:2B:12 Powered: yes
[bluetooth]# agent on
Agent registered
[bluetooth]# scan on
Discovery started
[CHG] Controller 68:A3:C4:0A:2B:12 Discovering: yes
[bluetooth]#
But no devices shows up. Any idea, where can be a problem?

EDIT:
May be there is a little problem but no idea how to solve it:
Code:
root # systemctl status bluetooth
● bluetooth.service - Bluetooth service
   Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; disabled; vendor preset: disabled)

Hi...

I'm not sure I can help you solve this but I was curious what the result is for...

Code:
rfkill list
Also, what distribution and version of Linux are you using?

Regards...

It doesn't seem, there is some software or hardware switch on any device:
Code:
# rfkill list
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: hp-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: hp-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
6: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
My distribution is ArchLinux - 4.6.4-1-ARCH. It is up to date I think.

Hi...

I'm sure you have a button somewhere on your keyboard that turns the wireless adapter on and off, however, nothing is blocked or turned off, so that's good.

From what I see here, it looks like you're not the only one with this problem. It appears to be some issue with the bluez driver/software, at least it was last year. I'm not sure if your case is related or a separate issue.

Unfortunately, I don't know anything about Linux and bluetooth (or bluetooth in general at this point) to help you troubleshoot. In case no one else here can, you can create a thread at the Arch forums and see if they have a solution.

Also, you might want to try other distributions to see if this problem can be duplicated. You may need to switch to one that works, in case the issue in Arch cannot be resolved.

Regards...

Thanks. I installed Ubuntu and the problem persists. I've found this thread http://forums.debian.net/viewtopic.php?f=5&t=125170, which is my problem but no solution there. I have to study more about the kernel and drivers as I have very little knowledge about that. Than I will try more debugging probably by using different drivers for my card.

I tried a little to solve my problem. I find out, that Ralink was sold to Media-Tek, which doesn't provide driver support for my chip anymore. On HP driver site there aren't newer drivers than for kernel 2.6., so I gave up.

I bought a new USB bluetooth tranciever from ebay and it came this friday. I tried today and it works fine. It's not worth for me to bother with internal BT card any more.
