10 Manipulate a cell phone's filesystem calling obexftp binary. This is a
11 complete user-mode solution, no kernel modules required (unlike SieFS or
12 such). The script implements all commands of Midnight VFS, except for
13 undocumented "run"; anyway there are no runnable files in the cell phone. The
14 script is written in Python because I love Python, the best of all languages ;),
15 and I need to parse XML directory listings from obexftp.
17 The script requires Midnight Commander 3.1+ (http://www.ibiblio.org/mc/),
18 Python 2.3+ (http://www.python.org/),
19 OpenOBEX 1.0.1+ (http://openobex.sourceforge.net/) and
20 ObexFTP 0.10.4+ (http://triq.net/obexftp).
22 Edit the script, and correct the shebang path, if your python is not in the
23 /usr/local. Edit the full path to the obexftp binary (see below). Put the file
24 in the /usr/[local/]lib/mc/extfs, and add a line "obexftp" to the
25 /usr/[local/]lib/mc/extfs/extfs.ini.
27 Create somewhere a transport file. The transport file may have any name, and
28 is expected to be a text file with at least one line defining the transport to
29 your device. Other lines in the file are ignored.
31 First word in the line is a transport name - Bluetooth, TTY or IrDA. The name
34 For the Bluetooth transport put there a line "Bluetooth CP:AD:RE:SS channel",
35 where CP:AD:RE:SS is the hardware address of the device you want to connect
36 to, and "channel" is the OBEX File Transfer channel; you can discover the
37 address and the channel for your device by using commands like "hcitool scan"
40 For the TTY put the device name: "tty /dev/ttyUSB0".
42 For the IrDA: just put "IrDA" in the file.
44 Now run this "cd" command in the Midnight Commander (in the "bindings" file
45 the command is "%cd"): cd transport#obexftp, where "transport" is the name of
46 your transport file. The script uses obexftp to connect to the device and list
47 files and directories. Please be warned that opening the VFS for the first
48 time is VERY slow, because the script needs to scan the entire cell phone's
49 filesystem. And there must be timeouts between connections, which don't make
50 the scanning faster. Midnight Commander caches the result so you can browse
51 and manipulate files and directories quickly.
53 Please note that manipulating the filesystem using your phone's internal
54 filemanager in parallel with the VFS leads to disagreement between the VFS
55 cache and the phone. It is not very dangerous but inconvenient. There is no
56 way to clear the VFS cache in Midnight Commander and reread the filesystem.
57 You have to exit the VFS (cd /, for example) and return back using cd
58 transport#obexftp command. Sometimes even this doesn't help - Midnight
59 Commander shows the same cached VFS image. Exit Midnight Commander and
62 If something goes wrong set the logging level (see setLevel() below) to INFO
63 or DEBUG and look in the obexftp-mcextfs.log file. The file is put in the same
64 directory as the transport file, if it possible; if not the file will be put
65 into a temporary directory, usually /tmp, or /var/tmp, or whatever directory
66 is named in $TMP environment variable.
