thinkpad x230 bluetooth problem

Hi,
I cannot use bluetooth on my thinkpad x230.

My kernel version is 3.15.5-2-ARCH

# lsusb
Bus 003 Device 004: ID 0a5c:21e6 Broadcom Corp. BCM20702 Bluetooth 4.0 [ThinkPad]

# lsmod |grep blue
bluetooth             380942  21 bnep,btusb
6lowpan_iphc           11556  1 bluetooth
rfkill                 15971  6 cfg80211,thinkpad_acpi,bluetooth
crc16                   1359  2 ext4,bluetooth

# hcitool dev
Devices:

The wiki (https://wiki.archlinux.org/index.php/Blueman) says: If only Devices: is dumped, the local Bluetooth device is unavailable.
What's wrong with my configuration?

Re: thinkpad x230 bluetooth problem

use bluetoothctl's scan command, I got this output

[bluetooth]# scan on
Discovery started
[CHG] Controller E0:06:E6:B8:21:5F Discovering: yes
[NEW] Device 20:08:ED:46:A0:C4 H30-T00
[CHG] Device 20:08:ED:46:A0:C4 RSSI: -69
[CHG] Device 20:08:ED:46:A0:C4 RSSI: -55
[CHG] Device 20:08:ED:46:A0:C4 RSSI: -65

What do -69, -55 and -65 mean? Is this an error?
