ad-hoc network on my Styleflying GPAD G10

To get this working, you will first have to root your styleflying android tablet.

This tablet is not like other android devices which are easily connected to adhoc by editing the tiwlan.ini and wpa_suplicant.conf. In fact, there is no tiwlan file on the device. We will have to use an alternate method, however, we will still be patching our wpa_supplicant.

The first step is to make an adhoc connection from your phone, laptop or desktop and name the ssid as ‘droidhoc’ and make sure you do not use a WEP key (it causes unnecessary problems). Set your ip address to static and use 192.168.0.1 (or you can use dhcp, but sometimes this causes problems). If you set static, then make sure you use a static IP, like 192.168.0.2, on your device under advanced settings. Set the mask to 255.255.255.0 and dns to 192.168.0.1.

The next step is to connect the gpad with adb and I will assume you know how to do that.

now we will type the following:

su (for superuser mode)
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system (mount partition as writable)
cp /data/misc/wifi/wpa_supplicant.conf /sdcard/ (copy configuration file to sdcard)
exit (to exit out of adb)
adb pull /sdcard/wpa_supplicant.conf / (pull the file off the sdcard to edit it)

Now edit the file with your text editor and enter the following after the line ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system:

eapol_version=2
update_config=1
ap_scan=2

network={
ssid="droidhoc"
scan_ssid=1
key_mgmt=NONE
group=WEP104
auth_alg=OPEN SHARED
priority=99
mode=1
}

Place the wpa_supp file back and change owner, permissions and reboot:
adb push /wpa_supplicant.conf /sdcard/wpanew.conf
adb shell
su
cp /sdcard/wpanew.conf /data/misc/wifi/wpa_supplicant.conf
cd /data/misc/wifi
chown wifi.wifi wpa_supplicant.conf
chmod 777 wpa_supplicant.conf
reboot

Once your phone is rebooted, we will download the HydTech’s adhoc wifi app from the market and run it.(app costs only $1.99)

Enjoy your new adhoc connection!
