Howto do nice things with your Nokia 6125 and Linux
On this page you will a find a short guide on how to get most from your Nokia
6125 mobile phone in connection with Linux.
The aim of this page is to provide up-to-date information in one place for
this phone since there is hardly any information at all on the 'net.
All comments, suggestions etc. are welcome. Please contact me at firstname.lastname@example.org.
After several years I had to buy a new cell phone since the replacement keypad
of my S55 disintegrated. So I decided to get a Nokia 6125, in particular
because of all the nice possibilities to connect it to other hardware.
Setting up the Bluetooth Connection
Start bluetooth on the mobile phone (in the default menu order: 4-8-1)
Set Bluetooth to 'On' and Visibility to 'Shown to all' / 'Permanent
Don't forget to switch back to 'Hidden' after finishing the setup.
For the basics (kernel, packages etc) please refer to the
Pairing phone and computer
The first thing that is new (and finally works again) is the process of pairing the phone with the computer running Linux.
Do the following as user root:
# cd /usr/share/doc/bluez-utils/examples/
# gunzip passkey-agent.c.gz
Install the following library if it is not installed yet (with apt-get, if using debian/ubuntu):
# apt-get install libdbus-1-dev
Compile the passkey-agent:
Run the passkey-agent with the PIN 1234 (not needed every time when connecting
in the future):
# ./passkey-agent --default 1234
Then connect the computer with the phone via bluetooth. Either use rfcomm or
rfcomm connect rfcomm0 00:16:BC:00:00:00
or obexfs -b 00:16:BC:00:00:00 -B 10 /mnt/
(replace the hardware address with the one of your phone you found out with
hcitool scan and choose another mountpoint instead of /mnt/ as
the phone displays
"Dial-up connection with <nameofthecomputer>-0"
"Exchange data with? <nameofthecomputer>-0"
Pairing with <nameofthecomputer>-0
Paired with <nameofthecomputer>-0
Allow this device to connect automatically?
After confirming the last question you don't have to run the passkey-agent
application any more and neither enter the passcode in the future (of course
only for this one phone).
Here I want to describe shortly the most useful applications for this phone. If
you have recommendations for other programs I haven't found yet don't hesitate
to send me an e-mail.
rfcomm / minicom
After connecting to the phone with rfcomm as shown above you can use the device
/dev/rfcomm0 lika a normal modem with ppp.
For testing purposes I recommend using minicom.
ObexFS is a great program. It allows you to mount the memory of the phone into
the normal Linux file-system so you can copy files to and fro in the shell,
with midnight commander or with any file manager.
You only have to run # obexfs -b 00:16:BC:00:00:00 -B 10 /mnt/
If the connection is lost, you have to unmount the device before being able to
reconnect: # umount /mnt; obexfs -b 00:16:BC:00:00:00 -B 10 /mnt/
With this program you use all the possibilites of the phone.
For details consult the man-page and the website.
Here are my settings in the file ~/.gammurc (works for me at the
moment only via Infrared connection):
VERY nice program to read the different kinds of data (contacts, messages etc) from the phone, export it to file, import it, write it to the phone.
IMO much more useful than the recent version of the Nokia data suite, the only
purpose of which is a full backup, for every other task you have to buy
programs of third party companies.
Theme editing with midnight commander / mc
You might wonder why I list a simple file manager application here. It is
because you can very comfortably edit the themes of the phone in midnight
The .nth-files are zip-archive-files (which are recognized and opened in
midnight commander by simply pressing <enter> on the file). In the
.nth-file you can find a file named theme_descriptor.xml in which
all data regarding the theme is listed. The file format is pretty
self-explaining. You can edit all colors in the usual RGB scheme and image
files. The files have to be copied into the zip-archive, of course.
I would suggest that you choose one of the existing theme files, make a backup copy and have a look at it and start playing around.
