Manipulate a cell phone's filesystem using obexftp. +ObexFTP Virtual FileSystem for Midnight Commander. Author: Oleg BroytMann . Copyright (C) 2004 PhiloSoft Design. License: GPL. +Manipulate a cell phone's filesystem calling obexftp binary. This is a complete +user-mode solution, no kernel modules required (unlike SieFS or such). The +script implements all commands of Midnight VFS, except for undocumented "run"; +but there are no runnable files in the cell phone. The script is written in +Python because I love Python, the best of all languages, and I need to parse +XML directory listings from obexftp. + The script requires Midnight Commander 3.1+ (http://www.ibiblio.org/mc/), -Python 2.2+ (http://www.python.org/), OpenOBEX 1.0.1+ (http://openobex.sourceforge.net/) +Python 2.2+ (http://www.python.org/), +OpenOBEX 1.0.1+ (http://openobex.sourceforge.net/) and ObexFTP 0.10.4+ (http://triq.net/obexftp). -Edit the full path to the obexftp binary (see below). Put the file to the -/usr/[local/]lib/mc/extfs, and add a line "obexftp" to the -/usr/[local/]lib/mc/extfs/extfs.ini. Then create somewhere a file called -"irda", "bluetooth" or "tty" to connect to the device using IrDA, Bluetooth or -TTY transport. +Edit the script, and correct the shebang path, if your python is not in the +/usr/local. Edit the full path to the obexftp binary (see below). Put the file +in the /usr/[local/]lib/mc/extfs, and add a line "obexftp" to the +/usr/[local/]lib/mc/extfs/extfs.ini. + +Create somewhere a transport file. The transport file can have any name, and is +expected to be a text file with at least one line defining the transport to +your device. Other lines in the file are ignored. + +First word in the line is a transport name - Bluetooth, IrDA or TTY. The name +is case-insensitive. -For the "bluetooth" put there a line "CP:AD:RE:SS channel", where CP:AD:RE:SS -is the hardware address of the device you want to connect to, and channel is -the OBEX File Transfer channel; you can discover the address and the channel -for your device by using commands like "hcitool scan" and "sdptool browse". -Other lines in the file are ignored. +For the Bluetooth transport put there a line "Bluetooth CP:AD:RE:SS channel", +where CP:AD:RE:SS is the hardware address of the device you want to connect to, +and channel is the OBEX File Transfer channel; you can discover the address and +the channel for your device by using commands like "hcitool scan" and "sdptool +browse". -Put a device name like /dev/rfcomm0 into the "tty" file. +For the TTY put a device name: "tty /dev/rfcomm0". -The content for the "irda" file is ignored. +For the IrDA: just put "IrDA" in the file. Now run this "cd" command in the Midnight Commander (in the "bindings" files -the command is "%cd"): cd bluetooth#obexftp. The VFS script use obexftp to try -to connect to the device and list files and directories. Plese be warned that -opening the VFS for the first time is VERY slow, because the script needs to -scan the entire cell phone's filesystem. Often obexftp fails to list a -directory, and the script retries after a second or two timeouts, which don't -make the scanning process faster. Midnight Commander caches the result. +the command is "%cd"): cd description#obexftp, where "description" is the name +of your file.
