Re: Bluetooth: hardware detected but no device

[Markos <markos@c2o.pro.br>]

Hi Deloptes,

First I installed rffkill:

bash# apt-get install rfkill

Then with the option "list":

# rfkill list
1: dell-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: dell-bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: no
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

I identified:  “Soft blocked: yes”.

To unblock:


bash# rfkill unblock 2

And after the list showed “Soft blocked: no”:

# rfkill list
1: dell-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: dell-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
4: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

After that the led of bluetooth in keyboard turned on and the command hcitool dev showed:

#hcitool dev
Devices:
        hci0	xx:xx:xx:xx:xx:xx

After that I tried to pair and connect using a GUI tool gnome-bluetooth and blueman, but I couldn't.

Neither gnome-bluetooth nor blueman can connect with my phone (Nokia E71).

Any tip?

Thanks for your attention,
Markos

this is false statement

it means it has initialized the BT subsystem(s)

try bluetoothctl
        list
        devices

check if the rfkill switch is enabled
try rfkill all
        rfkill bluetooth

on my older D530 it was ALT+F2 or F5 (cant recall) to enable disable the
wireless (wlan/BT)

I hope this helps
