Issue with bluetooth adapter

Hi there!

I'm trying to set up a bluetooth adapter on my raspberry pi (model 1 B+). The adapter comes from Farnell and it is supposed to be compatible with Raspian.

The adapter seems to be recognized, since:
$ lsusb
Bus 001 Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. SMC9512/9514 USB Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

But, when I fire up blueman-manager, I get prompted a warning window: "Bluetooth turned off - Bluetooth needs to be turned on for the device manager to function". I click on "Enable bluetooth" and the manger starts with the "Adapter" button grayed out.

I checked the troubleshooting section of the blueman project, and it suggests that my adapter might be at fault.
Running
$ bluetoothctl
[bluetooth]# list
doesn't get me any results.

The documentations suggests that the culprit might be a killswitch of some sort, but bluetooth seems enable on rfkill:
$ rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

I am running the latest Raspian image (tried both lite and 'regular' favors).
Any ideas, anyone?

Thank you very much.

What do you get from

Code: Select all

hciconfig - a
If it indicates the adapter is "DOWN" (I suspect it will), try

Code: Select all

sudo hciconfig hci0 up
If that fails, report the results.
