Mofi

Latest revision as of 16:18, 10 July 2009

Mofi is one of the applications that runs on the Openmoko Phones. For a list of all applications, visit Applications

Mofi allows phone users to search for and connect to available wireless access points (APs).

[edit] Where can I download Mofi?

Mofi is available on the Openmoko forge at http://projects.openmoko.org/projects/mofi/

Download the latest package at http://projects.openmoko.org/frs/download.php/277/mofi_0.02_armv4t.ipk

or alternatively, get the source from http://projects.openmoko.org/frs/download.php/271/mofi.0.02.tar.gz

See #Installation for info on how to install Mofi..

[edit] More Information

Mofi is written in Python and uses the PyGTK library to create the GUI. Mofi stores AP passwords in a configuration file, scans APs within range and generates a wpa_supplicant.conf from the information found. The system then uses the wpa_supplicant.conf to connect to the first accessible AP.

The Gnome UI can be used to view available access points, and specify which access point is preferred.

Information on the project can be found on the Moko forge at http://projects.openmoko.org/projects/mofi/

An RSS feed is also available at http://feeds.feedburner.com/MofiProjectNewsOpenmokoProjects containing latest news for the project.

[edit] Using Mofi

One change enables the disconnect functionality in 0.03 beta, which greatly increases the usability of Mofi. Just add the following to the end of /usr/lib/mofi/disconnect.sh

killall wpa_supplicant
killall udhcpc

This makes it possible to (I believe) shut down the wifi to conserve battery. You should also be able to connect at home, use the wifi, then disconnect, take the phone to your local wifi hotspot, then connect again, without trouble (I'm using FSO, and have yet to test the hotspot theory, however).

[edit] Installation

[edit] Through opkg

just scp the ipk to your FreeRunner, then install using opkg:

scp mofi_0.02_armv4t.ipk  root@192.168.0.202:/tmp/

ssh root@192.168.0.202
 > cd /tmp/
 > opkg install mofi_0.02_armv4t.ipk

Or install the ipk directly via opkg:

opkg install http://projects.openmoko.org/frs/download.php/277/mofi_0.02_armv4t.ipk

To run on your FreeRunner:

from the main menu choose the Applications section then "Wifi Mofi". Alternatively, mofi can be run from the console by typing mofi

However, you may have the message " Cannot satisfy the following dependencies for mofi: python-pygtk python-subprocess python-threading python-core python-misc python-lang python-pygobject" displayed instead.

[edit] From source

You'll have to add some dependencies:

opkg install python-core python-misc python-lang python-subprocess python-threading python-pygtk python-pygobject

there are some more, but when you try to run these will be indicated.. please post the additional dependencies to the project bug list, cheers:

http://projects.openmoko.org/tracker/?atid=710&group_id=165&func=browse

run ./install.sh - this will set up the environment and move files to your freerunner. note you may have to change the value of FREERUNNER to point to the correct IP..

then to run mofi open the console on your FreeRunner and type mofi.sh

You can also download the nightly SVN tree snapshot from https://projects.openmoko.org/snapshots.php?group_id=165

[edit] Screen Shots

[edit] If Mofi crahes

Mofi sometimes crashes with:

Traceback (most recent call last):
 File "/usr/lib/mofi/mofi_gui.py", line 30, in <module>
   import gtk
 File "/usr/lib/python2.5/site-packages/gtk-2.0/gtk/__init__.py", line 82,
in <module>
   init()
NameError: name 'init' is not defined

If this happens, edit the file /usr/lib/python2.5/site-packages/gtk-2.0/gtk/__init__.py and change the call to init() on line 82 to _init().
