Hints and tips

Adapting DoDWAN Apps to your Android smartphone

During startup, DoDWAN Apps tries to configure the Wi-Fi interface in ad hoc mode. For this, it needs to know the name of the interface and the name of its driver (kernel module). A wizard is included in the application that can find this information for a few common smartphones. But the wizard may fail, resulting in a message “Your smartphone is not supported yet”.

After a first (unsuccessful) launch of the application, you can provide the necessary information in the file /data/data/casa.dodwan.android/wifi.cfg. This is a text file that can contain commented lines (starting with #). The first uncommented line should be a white-separated list of 3 or 4 fields (the 4th is optional):

name of the interface
name of the kernel module
absolute pathname of the kernel module file
extra arguments for module loading (eg for firmware specification, empty in general)

For example, on a HTC Wildfire S, the wifi.cfg file has the following content:

# Info on Wi-Fi module and interface.
# interfaceName moduleName moduleAbsoluteFileName ExtraInsmodArgs
#
eth0 bcm4329 /system/lib/modules/bcm4329.ko

Try to relaunch DoDWAN Apps after having saved the file.

Verifying that the Wi-Fi ad hoc mode is set correctly

Once all necessary information on the Wi-Fi interface is obtained, DoDWAN Apps tries to put the interface in ad hoc mode. The icon showing a D sending radio waves should appear highlighted in the status bar. You can verify the ad hoc configuration parameters via the Setting menu (tab “More…”). The Wi-Fi status is shown at the bottom of the screen (scrolling may be needed to see it). You should see that the Wi-Fi interface is in “Ad-Hoc” mode and that the SSID is “DODWAN-ADHOC”.
