Cell phone as a modem via bluetooth connection solved

Post by carlos » Fri Sep 21, 2007 12:17 pm

I haven't search google yet, but I figure I would ask if anybody has tried to use a cellphone as a modem via bluetooth connection.

I've done this in windows and on a mac, but haven't tried it yet on linux. If anybody has had experience please post.

Yes. Sharp 770SH.

Done. All you need is a nice modern mobile phone which really really has a hardware modem built-in, i.e. it does not emulate anything via any bogus Windows-only software. If you can positively say 'yes' to this then it's relatively easy and Google will tell you the rest: Pair your phone with Linux so that your Linux thinks it has a modem device on a serial port (/dev/ttySxx) and then tell your Linux to do a PPP dial-up. If you feed your mobile phone with the right modem 'AT' commands it will even do EDGE/GPRS (= higher data rates) connections. All this can be Googled.

Would this apply to a USB connection (Sony-Ericson W700i)?
The phone has bluetooth I think but not my desktop
Want to be able to use it in case the phone line breaks
I just wonder if you know scorp - I get a bit ambiguous results in a quick google

Don't fix it if it ain't broken, don't break it if you can't fix it

Unfortunately no. The "Serial-Port Emulation over Bluetooth" is kind of a standard, so that even with Linux and Mac it is possible to do this. The USB connections however are mostly following proprietary standards and require a Windows software somehow. There are only very very few phones that will work tip top on Linux when connected via USB cable.

Buy a Bluetooth USB-stick ... they are cheap as dirt and most of those should work with Linux. I have a very old one from Acer. Works tip top.

There are better alternatives. I am considering to get myself a Huwawei E220 USB modem ... You can get 3.6 Mbps with it via HSDPA (= data link via UMTS).

One of our local Swiss GSM+Internet providers 'Sunrise' is offering those right now and I am seriously thinking of getting one. 3.6 Mbps via HSDPA is just f***ing awesome.

I know via Google that the Huawei E220 USB modem can be made to work with various Linux distros, incl. Ubuntu 7.04

If I were you I'd check if any of your providers in Sweden is offering something like this as well.

mobile phone modem

Post by daka » Sun Sep 23, 2007 1:56 pm

Hi

I have a lot of experience connecting with Huawei E220 and also with mobile phone as modem, as I live on a mountain with no phone line.

I have found bluetooth very problematic.

Best to disable the pin by putting the card in a phone and disabling it

With mobile phones many people are connecting quite easily with a USB cable. The "modem" is recognized as "ACM0"

Here is my wvdial.conf file that I use to connecta Nokia N80 and Nokia 6234:

[Dialer Nokia]
Phone = *99***1#
Username = vodafone
Password = vodafone
Stupid Mode = 1
Dial Command = ATDT
Modem = /dev/ttyACM0
Baud = 460800
Init2 = ATZ
Init3 = ATE0V1&D2&C1S0=0+IFC=2,2
ISDN = 0
Modem Type = USB Modem
Init5 = AT+CGDCONT=1,"IP","ac.vodafone.es";

--- so I end up connecting by opening a terminal and entering: wvdial Nokia

**** very simple with the cable.... and I use Feisty
___________________________________________________________

With the Huawei E220

wvdial.conf file looks like:


[Dialer hsdpa]
Phone = *99***1#
Username = vodafone
Password = vodafone
Stupid Mode = 1
Dial Command = ATDT
Modem = /dev/ttyUSB0
Baud = 460800
Init2 = ATZ
Init3 = ATE0V1&D2&C1S0=0+IFC=2,2
ISDN = 0
Modem Type = Analog Modem
Init5 = AT+CGDCONT=1,"IP","ac.vodafone.es";

But the Huawei is not automatically recognized and you have to enter, in terminal:

sudo modprobe -r ehci_hcd

then re-start computer..... open terminal.... enter wvdial hsdpa .... and you are connected
(again this is in Feisty..... it is more complicated in previous distros

Good luck

Daka

That highly depends on the brand. It seems that Nokias do a considerable better job at this. Other phones, such as my otherwise brilliant Sharp 770SH, will do nothing if you connect them via USB to a Linux system.

Excellent. This surely will be useful for people searching for config examples. Thanks :D

Just to post here that I got my HSDPA/UMTS modem .... but it's not a Huawei E220, it's a Novatel "Ovation MC950D" ... It looks like a black USB-stick.

Basically you can follow the instructions given here (although this stuff is for a different model, the instructions worked perfectly !!):
http://www4.sprint.com/pcsbusiness/down ... _Guide.pdf

Only minor difference: The product ID is '0x4400'. So when the instructions in the PDF tell you to issue commands such as "sudo modprobe usbserial vendor={ID} product={ID}" then these are the correct values:

Code: Select all

sudo modprobe usbserial vendor=0x1410 product=0x4400
This thing works almost instantly. I am using it right now. :D
