[Q] [XPERIA P] Configuring wireless adapter - Sony Xperia P, U, Sola, Go

Hi,
The goal of my project is to implement mobile ad-hoc network routing protocol(AODV).
My problem is that I need to reconfigure the wireless driver/adapter to be able to work in ad-hoc mode. This means receiving packets from other nodes and resending packets if 2 nodes which want to communicate are far away from each other.
I don't have experience with drivers changing and I'm noob in Linux.
For better imagination, I've got source code for the Nexus One and HTC Hero and this code should be able to change wireless drivers configuration on these devices.
Here's the code for Nexus One:
Code:
case 0: //NEXSUS
system("insmod /system/lib/modules/bcm4329.ko");
snprintf(cmd, sizeof cmd, "ifconfig eth0 %s netmask 255.255.255.0", ip);
printf("\ncmd: %s\n", cmd);
system(cmd);
system("ifconfig eth0 up");
system("iwconfig eth0 mode ad-hoc");
system("iwconfig eth0 essid nexusbac");
system("iwconfig eth0 channel 6");
system("iwconfig eth0 commit");
break;
And here for the HTC Hero
Code:
system("insmod /system/lib/modules/wlan.ko");
system("wlan_loader -f /system/etc/wifi/Fw1251r1c.bin -e /proc/calibration -i /data/local/bin/tiwlan.ini");
snprintf(cmd, sizeof cmd, "ifconfig tiwlan0 %s netmask 255.255.255.0", ip);
system(cmd);
system("ifconfig tiwlan0 up");
break;
I was wondering if you could give me some advice what commands to use.
My Sony Xperia P is Rooted and I'm using Honami Moonwalker V8 ROM.
It seems that command ifconfig is not working. If I try to execute e.g
Code:
ifconfig eth0 up
android shell throws this error:
ifconfig eth0 up
error: SIOCGIFFLAGS (No such device)
Thank you for your answers. I really appreciate the time you give to this thread.

Try wlan0

thanks ChikeD, it seems that wlan0 works fine for ifconfig but it seems that iwconfig binary is missing. Are there any alternatives for this shell command in Android?
I tried to use iwconfig binary from Android tethering project but using it throws an error like this:
Code:
[email protected]:/ # iwconfig wlan0 essid xperiaP
SET failed on device wlan0; Invalid argument

There is iw binary see what you can make out of that.

Thanks, this looks very interesting. I'll give some feedback later if I manage to make it work

You changing the driver source?

I just need to make it work in the ad-hoc mode. If think it's an IBSS mode. I just need to figure out, how to setup this type of connection

Assuming(thinking) is not an option.
From a brief look at the sources it seems the ad-hoc is not implemented.

Sorry for delay.
So you don't consider an IBSS mode as a true ad-hoc mode? Am I right? I thought that IBSS is like a synonym of the term "ad-hoc"
According to this website: http://en.kioskea.net/contents/804-wifi-modes-of-operation-802-11-or-wi-fi
It should be the same.
To my problem. I've made this commands to work:
Code:
/*Bring the interface up (an additional step like rfkill unblock wifi might be needed: ip link set wlan0 up*/
system("iw dev wlan0 set type ibss"); //Set the operation mode to ibss ):
system("iw dev wlan0 ibss join MyAdHocNetwork 2412") //frequency for channel 6: 2437, 2412 for channel 1...
system("ip addr add 192.168.1.2/24 broadcast 192.168.1.255 dev wlan0");
system("ip route add default via 192.168.1.1");
What do you think?
Thanks

Seems so, does it work?

I don't know yet. I seems that everything is set up. Now I need to buy at least another xperia p or similar smartphone to test communication.
I am now trying to run ad-hoc mode on HTC Desire and Tablet Prestigio Multipad 3270b. But it's pain, because they don't have iwconfig and iw binaries.

So what is the purpose of this?
Doesn't have to be a smartphone, you can do it with a wireless pc/laptop

Thanks for the links. The goal of my project is to run ad-hoc mode on android. I will definitely test this later using windows but I am running out of time, so I'm focusing mainly to at least changing wireless mode from managed to ad-hoc. That's the most difficult thing because right now I am not able to change wireless mode on HTC and Prestigio using linux system commands. Maybe there is a way to change wireless mode programmatically (Java or C) but I haven't found that information yet.
