Hello, thanks for the howto. I have a Nokia E51 and Debian Lenny. I am trying to configre it but I have a error.

These are my steps:

1. Configure bluetooth:

# rfcomm
rfcomm0: 00:1D:6E:xx:xx:xx channel 4 clean

(on E51 the “Dial-Up Networking” service comes in channel 4)

2. I write to my 3G service provider and they send connections information:

- No need user or pass.
- APN: internetmas
- Telephone number: *99#
- initial command: +CGDCONT=1,“IP”,“internetmas”

3. So I configure /etc/wvdial.conf this way:

[Dialer Defaults]
Phone = *99#
Password =
Username =
Stupid Mode = 1
Dial Command = ATDT
New PPPD = yes
Remote Name = “*”

[Dialer Nokia]
Modem = /dev/rfcomm0
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E0 S0=0 &C1 &D2 +FCLASS=0
Init3 = +CGDCONT=1;”IP”;”internetmas”;
ISDN = 0
Modem Type = Analog Modem

4. This is my modem permisions:

# ls -l /dev/ | grep rfcomm0
crw-rw—- 1 root dialout 216, 0 2009-08-08 15:14 rfcomm0

And this my connection error:

# wvdial Nokia
–> WvDial: Internet dialer version 1.60
–> Cannot get information for serial port.
–> Initializing modem.
–> Sending: ATZ
ATZ
OK
–> Sending: ATQ0 V1 E0 S0=0 &C1 &D2 +FCLASS=0
ATQ0 V1 E0 S0=0 &C1 &D2 +FCLASS=0
OK
–> Sending: +CGDCONT=1;”IP”;”internetmas”;
–> Sending: ATQ0
OK
–> Re-Sending: +CGDCONT=1;”IP”;”internetmas”;
–> Modem not responding.

I don’t know which is the problem. Can someone help?

Thanks for all and best regards.

I cannot get wvdial to see my modem. I get the following.

[root@localhost andrew]# wvdial vodafone
–> WvDial: Internet dialer version 1.60
–> Warning: section [Dialer vodafone] does not exist in wvdial.conf.
–> Cannot open /dev/modem: No such file or directory
–> Cannot open /dev/modem: No such file or directory
–> Cannot open /dev/modem: No such file or directory

I edited the files as stated and although I am with O2 in Germany I thought I would leave your text as is to see what happened before trying to make changes.

It seems that the modem file is missing and having searched my system I find a file called modem.conf but looking through it I cannot see anything relevant.

What file should I be looking for in /dev/modem?

I can browse my phone via bluetooth and have done hciscan to determine the mac address and rfcomm channel..

I am working on Mandriva 2009.

wsjunior:
You might want to find out if the phone is locked with a PIN, or refer to http://www.shapeshifter.se/2008/04/30/list-of-at-commands/ for a list of AT+CGDCONT alternatives. Try AT+CGDCONT=? to find out if your modem supports “IP” as a protocol type.

You have made a little typo; the first init string must be ATZ+CPIN=”xxxx” where xxxx is the PIN code.

Bonus: If you want to use this configuration with Vodafone in Spain, you must change “ac.vodafone.es” for “airtelnet.es”
