Bluetooth GPRS Modem Success (Nokia, AT&T, wvdial)

[togume]

I was able to connect my laptop running 7.10 to the internet using my Nokia E70 using bluetooth through AT&T's network after putting together information found on various websites and posts. As always, I hope this will be useful for others as well.

First, make sure you have bluetooth utilities:

sudo apt-get install bluez-gnome bluez-utils

(I installed these a long time ago, please correct me if I'm missing something)

First, find the MAC address of your device:

togume@togulaptop:~/Desktop$ hcitool scan
Scanning ...
        00:12:D2:0A:XX:YY       Togucell

Then, find the channel used for dial up networking using the MAC you just found:

sdptool browse 00:12:D2:0A:XX:YY
...
Service Name: Dial-Up Networking
Service RecHandle: 0x1002e
Service Class ID List:
  "Dialup Networking" (0x1103)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 2
Language Base Attr List:
  code_ISO639: 0x454e
  encoding:    0x6a
  base_offset: 0x100
Profile Descriptor List:
  "Dialup Networking" (0x1103)
    Version: 0x0100

In this case (and for Nokias) it's channel 2. This will be used to configure the bluetooth connection. To do so, open up /etc/bluetooth/rfcomm.conf with your favorite editor.

rfcomm.conf:

rfcomm0 {
bind yes;
device 00:12:D2:0A:XX:YY;
channel 2;
comment "Dial-up networking";
}

Next, restart bluetooth services:

sudo /etc/init.d/bluetooth restart

Now the final part is to configure wvdial. Again, open up /etc/wvdial.conf with favorite editor. The following is the configuration I used for AT&T. The name of the dialer is what will be used with the wvdial command later on.

wvdial.conf:

[Dialer E70BT]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=, ,"wap.cingular"
Modem = /dev/rfcomm0
Phone = *99***1#
Username = WAP@CINGULARGPRS.COM
Password = CINGULAR1
New PPPD = yes
BAUD = 460800
Stupid Mode = 1

Now, try out wvdial:

sudo wvdial E70BT

The first time I did this, the phone asked for a passcode, I entered anything into the phone, and then the laptop asked for the same. After this I did not need it again.

That's it. You should see something along the following:

togume@togulaptop:/etc/bluetooth$ sudo wvdial E70BT

To exit, ctrl+c.

A couple notes:

1. I set my laptop as a trusted device on my phone, that way it does not ask for permission when the connection is initiated.

2. When testing this out, make sure other connections are disabled. The first time I tried it the packets went nowhere because I had my wireless turned on and disabled it after making the bluetooth modem connection.

3. This should also work with ISP@CINGULARGPRS.COM, however, I don't believe I have that plan. Make sure you have unlimited data, though, or the bill might be something worth fighting about. I pay $20 for unlimited data.

Best,

Tomás

It works very well and excelent tutorial, Worked on Fluxbuntu 7.10 using a standard bluetooth adaptor and a samsung a737 on the new AT&T network

Thanks Thomás!!

I tried this and I was able to connect to the phone etc. But when I start wvdial, I get " No Carrier! Trying again." for ever.

sudo wvdial E70BT
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

NO CARRIER

I am trying to dial to ATT using a samsung A737. Any idea why I am getting this ?

I get the exact same error. I make to the point of dialing the number ATDT*99***1# it pauses for a few minutes then I get the msg about no carrier.
I am using a Moto Krzr with the unlimted Data package
