Installing OpenOBEX

To manage files on your mobile phone, you'll need two applications: OpenOBEX and ObexFTP. You can either try to install it using your package manager (yum, apt-get etc) or, download the sources from Softpedia: OpenOBEX and ObexFTP.

If you decide to install them from sources, you will need to have the following packages installed on your system: gcc make automake1.4 autoconf libusb-dev libtool.

Finally, follow these steps: OpenOBEX:

code

$ mkdir ~/usbobex
$ tar xfz openobex-1.3.tar.gz
$ cd openobex-1.3
$ ./configure --prefix=$HOME/usbobex --enable-apps
$ make
$ make install

ObexFTP

code

$ bzip2 -cd obexftp-0.20.tar.bz2 | tar xf -
$ cd obexftp-0.20
$ ./configure
$ make
$ sudo make instal

Set UDEV permissions

- Open a terminal and type lsusb. - Look for a line similar to this: Bus 001 Device 005: ID 0421:0428 Nokia Mobile Phones - In this example, 0421 is the VendorID, while 0428 is the ProductID. - Add the following line to /etc/udev/rules.d/40-permissions.rules in Ubuntu: BUS=="usb", SYSFS{idVendor}=="VendorID", SYSFS{idProduct}=="ProductID", GROUP="plugdev", USER="yourUserName" - Replace VendorID, ProductID and yourUserName with the correct values.

Using ObexFTP

- Open a terminal and type:

code

$ ~/usbobex/bin/obex_test -u

Your should see something like:

code

Using USB transport, querying available interfaces
Interface 0: Nokia Nokia 6230i (null)
Interface 1: Nokia Nokia 6230i (null)
Interface 2: Nokia Nokia 6230i (null)

Listing directories: (Run command as normal user with Ubuntu and as root with everything else)

code

$ obexftp -u 1 -l

-u 1 connects to interface 1, while -l will list directories and files in the root directory.

Downloading files

Let's say we want to get 011.mp3 from the Music files directory:

code

$ obexftp -u 1 -c 'Music files' -g 011.mp3

Uploading files

To upload file.txt from Desktop to Documents directory on the phone:

code

$ obexftp -u 1 -c 'Documents' -p path/to/Desktop/file.txt
