This provides access to the nokia e90 memory using the obex protocoll. The memory is mounted like a usual filesystem. Bandwith when accessing via bluetooth is 23kbyte/sec. Dunno what the bottleneck is there, i/o to the memory is it not (becaus e usb-transfer is faster), its also not the bluetooth-throughput (because internet-usage from a pc via bluetooth is faster).

Accessing the e90 via wlan with opexftp (-n option) didnt succeed here, apparently the obex-service is only provided via bluetooth and maybe irda. Using the usb-cable and mounting the e90 as usb-storage-device is the fastest way.

1. compile a kernel with CONFIG_FUSE_FS as module or build in
2. modprobe fuse
3. apt-get install obexfs obexftp # or get, compile and install it from http://dev.zuckschwerdt.org/openobex/wiki/ObexFs
4. activate bluetooth on the e90
5. hcitool inq # scan for the e90, get the bluetooth-address
6. sdptool browse 00:1A:89:C1:21:A6 # can be used to look for the phones services

$> obexftp -b 00:1A:89:C1:21:A6 -l # this looks for a channel on your device providing obex-services. Example
Browsing 00:1A:89:C1:21:A6 ...

1. mkdir /mnt/e90 # create mountpoint
2. obexfs -b 00:1A:89:C1:21:A6 -B 11 /mnt/e90 # lets mount it. The nokia e90 is now accessable under the mountpoint.
3. obexfs -b 00:1A:89:C1:21:A6 -B 11 – -d -f /mnt/e90/ # this could be used for debugging. Wont detach from console.
4. fusermount -u /mnt/e90 # use this for umounting
5. extension for automounter is possible ofcourse
