The command 'rfcomm con...' does not transfer any audio signal itself, so do not use it at all yet. From the laptop side you need to do:

# hsmicro xx:xx:xx:xx:xx:xx 12
  or
# hsmicro xx:xx:xx:xx:xx:xx 13

where xx:xx:xx:xx:xx:xx is the address of nokia. Then try to make a phonecall and you should be able to listen from the laptop speakers. I have try this and worked fine. I haven;t tried to send audio from the pc's microphone to the mobile yet, however I am quite convinced that this is a one-way audio transmission.

Thanks for your help:

now I can start hsmicro on channel 12 or 13 and the phone sees an 
headset connected, but on the linux console I get the error message

---
./hsmicro  00:02:EE:0D:47:5F 12
Voice setting: 0x0060
RFCOMM channel connected
Can't connect SCO audio channel: Connection refused
---

any idea on that ?

Thanks again

Do you have the SCO module loaded?

'modprobe sco'

[Bluez-users] Linux audio gateway and headset feature

[Paolo Arcagni]

Hi gentlemen.

I am setting up my Linux box to use an USB Bluetooth interface in order 
to talk to my nokia 6310. I can browse the internet using GPRS from the 
laptop enabling the rfcomm0 interface with the command

rfcomm conn 0 xx:xx:xx:xx:xx:xx 1

pointing pppd to /dev/rfcomm0.

The question is: which is the right procedure to use the laptop 
multimedia subsystem as an headset for the phone ? On windows2000 this 
kind of setup worked fine....

I can obtain a connection with the command

rfcomm conn 0 xx:xx:xx:xx:xx:xx 12

and accepting the connection on the cell phone the output is

Conmected /dev/rfcomm0 to xx:xx:xx:xx:xx:xx on channel 12
Press CTRL-C for hungup

On the phone display I can see the symbol for the connected headset, I 
cannot hear the sound on the phone, but I have no sound on the Laptop.

My Laptop is using ALSA with a ESS ES1978 audio board and the sound in 
gnome works fine.

Where is the mistake ?!?

Thanks for your help

===============================
Gentoo Linux with kernel 2.6.6
ALSA Drivers for the ESS ES1978
Gnome 2.6
