Hello all,

I'm experimenting a problem trying to connect internet via GRPS through bluetooth using my Nokia 3650 and a Linux Box with a usb-dongle bluetooth BT3030, via pppd.

The connection between the mobile and the PC via bluetooth is working fine. I can transfer data in the two ways: PC->mobile , mobile->PC, using the bluez driver.
So, now when I try to access the internet via GPRS a got this message when I call "pppd"

root@emerald:~# rfcomm 1 xx:xx:xx:xx:xx:xx 9
Connected /dev/ttyU1 to xx:xx:xx:xx:xx:xx on channel 9
rfcomm_send_data: DLCI 18 not connected
rfcomm_send_data: DLCI 18 not connected
rfcomm_send_data: DLCI 18 not connected
rfcomm_send_data: DLCI 18 not connected

My pppd scripts are:

in /etc/ppp/chat-gprs
-----------------------------------

TIMEOUT         5
ECHO            ON
ABORT           '\nBUSY\r'
ABORT           '\nERROR\r'
ABORT           '\nNO ANSWER\r'
ABORT           '\nNO CARRIER\r'
ABORT           '\nNO DIALTONE\r'
ABORT           '\nRINGING\r\n\r\nRINGING\r'
''              \rAT
TIMEOUT         12
OK              ATE1
OK              'AT+cgdcont=1,"IP","tim"'
OK              ATD*99***1#

-----------------------------------

and in /etc/ppp/peers/gprs
-----------------------------------
/dev/modem 57600
connect '/usr/sbin/chat -v -f /etc/ppp/chat-gprs'
noauth
defaultroute
debug
-----------------------------------

I have a symbolic link from /dev/ttyU1 to /dev/modem

And when I call: "pppd call gprs"
I got that message "rfcomm_send_data: DLCI 18 not connected"

Does anyone can help me with this?
Sorry about the long message...

TIA,

use the kernel RFCOMM layer.

Hi Marcel,

Sorry about my innocence :-)))), but when you say "use the kernel RFCOMM layer", you mean load the module "rfcomm" (or even have it built in the kernel) ???
If so, I already have the module(rfcomm) loaded...
Se my lsmod:

-------------------------------------------------
And the problem still remains...

And if ""use the kernel RFCOMM layer"" has no meaning with I sad before, can you tell me what it is?
Any other idea?

Best Regards!!!

loading the kernel module is enough, but it seems that you have you have the wrong rfcomm utility. The BlueZ utils packages also contains a rfcomm program that can be used to setup /dev/rfcomm0 TTY devices that work exactly like a serial port. Of course you have to create the device nodes first.
