Getting ad-hoc mode on Android

The german page android-hilfe.de describes quite nicely how to get ad-hoc mode running on the Samsung Galaxy.
For the non-german speakers here is a summary:

The trick is to use the wpa-supplication settings file to force the driver to go to ad-hoc mode. By the default the tiwlan cmd line utility does not understand ad-hoc mode.

1. turn on Wi-Fi and start the adb shell
2. go to wpa_cli command shell:
   su -c "/system/bin/wpa_cli -p /data/misc/wifi/"

3. scan_resultsshows you the existing networks.
4. add_networkadd a new network. Shows a number. Here the number is "2"
5. set_network 2 mode 1
set_network 2 ssid "olsr.freifunk.net"
set_network 2 bssid 02:ca:ff:ee:ba:be
set_network 2 frequency 2457
set_network 2 key_mgmt NONE
enable_network 2


6. ap_scan 2
7. select_network 2
8. if this did not work, then try again:ap_scan 2
9. This is now what you get:
   
   su -c "/system/bin/wpa_cli -p /data/misc/wifi/"
   wpa_cli v0.5.10

Installing Olsr

For the Samsung Galaxy you can use the following file: pre compiled samsung android version of olsrd.
You might have to edit thedata/local/etc/olsrd.conffile to suite your needs.

Starting olsr

From the Terminal or adb shell:olsrd -f /data/local/etc/olsrd.conf -d 1. You should see some routes in your kernel routing table if you are connected to an ad-hoc network which has other olsr nodes.
