Hi,

Did anyone had success connecting to a Wii console using a PC? (Instead of an android device.)
Did anyone check if it's possible to connect with the Jelly Bean?

I wrote two programs trying to connect to the Wii, one of them is for jailbroken iDevices, the other is for PC.

The PC program starts by deleting all other SDP entries, and puts the Wiimote entries, it clones the output
of "sdptool browse" and "sdp records --tree" nearly perfectly, the only thing it misses is a sdp record with handle 0x00
(I guess the SDP's server own sdp record), since it's a special handle, and I couldn't add it like the others...
Despite cloning bluetooth sdp record so good, the Wii still fails to connect... =/

Both programs are a bridge between an UDP connection for Dolphin Wii emulator (http://forums.dolphin-emu.org/Thread-patch-udpwii-use-iphone-as-wiimote-new-nunchuck-and-ir-support) and the bluetooth connection for the real Wii. They can already connect to the Dolphin emulator faking a real wiimote (i.e., through bluetooth, and not UDP).

If anyone manages to connect a Wii to a PC, please let me know, I would love to see an android device controlling a Wii, even if a PC is necessary as a proxy. As I said, I already have a program that implements the protocol, all I need is to make the initial connection.

I developed an Android application working with UDP, using Dolphin:

Hi all,

If you're interested, here is my work I've done one year ago. The aim was to connect a Wii Balance Board to an Android device in order to display your weight. I didn't have time do finish it, and I had no more motivation since it didn't work on Samsung an HTC ROMs. Actually it works on all devices using a custom ROM based on Google stock ROM, like CyanogenMod. But on the Android Market, the main users don't use such custom ROMS.

The fact is I access to the bluetooth library throught the linux kernel, using Android NDK to make a dll linked to libbluetooth.so. This libray is modified on Samsung and HTC ROMs and it doesn't work, but I developped it on a HTC Hero with a CynogenMod ROM and it works.

This was my first project on Android, so the code might not be good at all and I didn't return on it since I abandoned. Maybe it doesn't even compile...

The code to understand is in jni\androidWiiBridge.c interfacing with WiiUse library [sourceforge.net]

and src\com\droidprod\wiiweight\WiiboardManager.java to have a Java API.

It can work with Wiimote, you just need to adapt the code.

I hope it can help.

The real question is, why would you want to? Unless your plan is to use it like a faux Wii U, I don't see any point to it.

This stuff is great for parties, especially for nerd gamer, moneyless college students like myself. Imagine if people didn't have to bring extra controllers, so long as they had a (like most everyone) smartphone.

If you guys get this working, hunt me down please, as I would love to get a few tricks working in here that would let the Android device have more complete Wiimote functionality.

Well clearly these people do seeing as this topic is four pages long, which is quite lengthy for this forum. No one would force you to use it, you don't need to express an opinion on every thread you read.

For those keeping score, IceCreamSandwich did not improve the Bluetooth API. I've also tried the Bluetooth reflection hack on both my Xoom (4.0.3) and Galaxy Nexus (4.0.4). No luck. Here's looking forward to JellyBean! Or CM9 perhaps?

technologiclee - I did create an .apk, but it only tests a device to see if the Bluetooth reflection hack works on it.

Re: Use android device as remote for the WII

Is there an .apk that I can work with?

Re: Use android device as remote for the WII

I hope that IceCreamSandwich makes things easier :/

But great to hear that you guys are not going to give up!

nope, nothing new. :) I was thinking about installing Linux and compiling me a custom Cyanogenmod kernel. no time right now, maybe when it gets colder. can't wait to pick things up again. don't worry rikmer, I know where to find you!

Hey Greg! Any new infos regarding the project. Always looking forward to help out.

Well, I created the socket and attempted to call bindListen(), that's as far as I ever get before an exception gets thrown. That brings up an interesting point though...if we do get bindListen() to work without throwing an error, the next problem we may encounter is calling accept().

Re: Use android device as remote for the WII

Hi,

I tried to open the L2CAP Server Socket with Reflections. (I have HTC Desire) :

Class ss_class = Class.forName("android.bluetooth.BluetoothServerSocket");

Constructor ss_constructor = ss_class.getDeclaredConstructor(int.class, boolean.class, boolean.class, int.class);

ss_constructor.setAccessible(true);

BluetoothServerSocket serverSocket = (BluetoothServerSocket) ss_constructor.newInstance(3, false, false, 12);

Log.v(TAG, "ServerSocket is null: " + (serverSocket != null));

while(running){

BluetoothSocket socket = serverSocket.accept();
}

...

Howerver, bindListen doesn't throw the acception, but serverSocket.accept() does....

Somehting more, as I was browsing the bluez code I saw this thing:

if (type == BT_IO_L2RAW) {
g_set_error(err, BT_IO_ERROR, BT_IO_ERROR_INVALID_ARGS,
"Server L2CAP RAW sockets not supported");
return NULL;
}

in ../external/bluetooth/bluez/src/btio.c : Line 1264

So, Greg, are you sure you opened the L2Cap ServerSocket !?!!?

Re: Use android device as remote for the WII

FelixL — Sat, 14 May 2011 13:56:44 +0200

Did you update your Xoom to 3.1 yet? And did you read my email concerning the source-code off the test app?
Thanks!

Re: Use android device as remote for the WII

Greg — Sat, 14 May 2011 01:40:27 +0200

Not much new on this end. I tried the test app on my Xoom, didn't work there either. Not a surprise.

Re: Use android device as remote for the WII

Anything new?
I have tried to compile the kernel for the Blade, but didn't work, CM7 was no problem to compile, but has a prebuilt kernel. I will ask some guy from the UK for help this weekend.

Re: Use android device as remote for the WII

rikmer — Mon, 18 Apr 2011 14:27:35 +0200

Just for the info: Test App also works on HTC Desire with Android 2.2 Stock Sense.

Also found something in the bluez stack which could be the problem. It is in btio.c in function l2cap_bind(). In Android stock bluez implementaion it reads:

static int l2cap_bind(int sock, const bdaddr_t *src, uint16_t psm, GError **err)
255 {
256 struct sockaddr_l2 addr;
257
258 memset(&addr, 0, sizeof(addr));
259 addr.l2_family = AF_BLUETOOTH;
260 bacpy(&addr.l2_bdaddr, src);
261 addr.l2_psm = htobs(psm);
262
263 if (bind(sock, (struct sockaddr *) &addr, sizeof(addr)) < 0) {
264 ERROR_FAILED(err, "l2cap_bind", errno);
265 return -1;
266 }
267
268 return 0;
269 }

and in HTC Desire bluez:

static int l2cap_bind(int sock, const bdaddr_t *src, uint16_t psm)
{
struct sockaddr_l2 addr;

memset(&addr, 0, sizeof(addr));
addr.l2_family = AF_BLUETOOTH;
bacpy(&addr.l2_bdaddr, src);
addr.l2_psm = htobs(psm);

return bind(sock, (struct sockaddr *) &addr, sizeof(addr));
}

I have communicated my findings to thalamus_ and am waiting for his opinion.

The thing is that even if this is the problem that it will depend on the mobile producer if it is implemented. So the easier way will always be through the kernel because this part is much more comfortable to exchange, if the mobile is rooted.

The chance that Google will change this part is, I suppose, rather small. But I could be wrong. At least we should try to contact them an tell them about.

Before anything we have to wait if the this change will produce the wanted behavior.

Nice!!! That is some awesome detective work rikmer! But these kernels are device specific correct? When you say "mainline kernel", do you mean for the Desire? Or for stock Android? I'm not very familiar with all this really low level OS stuff. I guess I'm just trying to figure out what to do with this new info. Do I need to find someone who can compile me a custom Droid kernel?

It is the mainline android stock kernel.Unfortunately it means that you have to find somebody who compiles you a custom kernel. But there should be some guys at xda-developers who could provide you with one. I am communicating with thalamus_ at the moment because he found out that the main problem really is in the bluez stack. What we can do about this issue I don't know right now. I will post infos as I get them.

EDIT: It does not depend where the kernel comes from but it is device and rom specific.
@Greg: At least you would need a rooted Droid and modified kernel appropriate to the used rom.
@FelixL: Looking forward to know if this modification also works on the Blade (it should).

Re: Use android device as remote for the WII

FelixL — Sat, 16 Apr 2011 23:08:39 +0200

Great news :-)
I'm reinstalling Ubuntu at the moment to get it work on the Blade.

Edit: Greg, you need either someone who can do this for you or a Linux distribution, some time to download the kernel source and little skills in using a command line.

Consider this problem solved!!!

After browsing the kernel source and writing an email to a guy at qualcomm who did a lot of the bluetooth programming ( I found his address directly in the .c files) a guy at xda-developers ( my personal hero now) named thalamus_ ( a lot of credits to him) compiled me a custom kernel with the appropriate changes to make this work. Here is the changelog https://github.com/thalamus/kernel/commit/bc2fe51d09917b1d6dbe5d6caad1e4031799d278 . You only have to remove this function in /net/bluetooth/l2cap.c, compile the kernel and the test app is working on my HTC Desire ( Oxygen 2.0.3 ).

The deleted function is in the mainline kernel so it is not the best solution to only delete it. thalamus_ is looking into the HTC Desire HD source to find how they realised it. At least we know how to solve the problem for now.

so long ....

Erik

EDIT: As soon as the official HTC Desire Sense 2.3 is out I will test it with this system. If it works then there are at least some more devices where the WiiMote could work.

Hey!

I wonder if somebody has tried to test the app on a HTC Desire HD with CM7. If it won't work than we can be sure that it has something to do with some HTC customisation. Would be at least very interesting.

I tested it on my HTC Desire with Oxygen 2.0.3 (custom Gingerbread ROM) and it didn't work. I also tried to install a RIL from the HTC Desire HD but it didn't change anything. So I think that it is highly probable that it is a kernel issue.

I think I will try to reflash the original ROM onto my Desire to see if it will work under this circumstances and if I am not too stupid also try to compare the bluez source codes.

I will post my results if any.

Re: Use android device as remote for the WII

Greg — Mon, 28 Mar 2011 21:05:06 +0200

The Nexus One not working is not surprising. That is a Google Experience device and HTC probably did not do anything custom. Interesting pattern has emerged though, HTC's customizations seem to make a difference. I have access to a Droid Eris, I'm going to try the test app on that device and see what happens.

Thanks for the update Felix!

Re: Use android device as remote for the WII

Trrrriple post!

I've made a post in a german android forum to get more devices tested:
[www.android-hilfe.de]

You can find the results in the first post, so far only the HTC Desire HD (which is an Evo 4G without the 4G ;)) and the Galaxy S have positive results! On the other side, not even the Nexus One did work. What I think: the bluetooth architekture shows that bluez has a kernel-part and a userspace part.
[source.android.com]

Samsung and HTC have most likely replaced at least the kernel-part, or changed something there.
(Just saw that Greg mentioned this already:
"The problem is someting really low level is not allowing it. Perhaps something in bluez is disabling L2CAP??"
)
Could somebody have a look at the bluez-source-code for the HTC Evo and compare it to the source-code of a device where it doesn't work?
[developer.htc.com]
Maybe we could even compare the kernel parts of bluez, since all kernels are open source? I think it's more likely that this is hidden somewhere in the kernel part, since L2CAP ist positioned there in the picture above.

CM7 on the ZTE Blade: JavaIOError, permission denied.
Honeycomb on the Blade: no working Bluetooth, yet.

Re: Use android device as remote for the WII

FelixL — Thu, 10 Mar 2011 18:30:13 +0100

No problem, as you may have noticed the same happened with the message you sent me :D
And no, there seams to be no option for notifications on pm.

Thanks for the app!
I will try it with cm7 and with honeycomb on the Blade.

Sorry guys, I just realized all the private messages you've been sending me have been sitting in my wiibrew inbox. I guess there is no email notification, or the emails are getting swallowed. Anyways, I'll send out that test app later today!

Hi Greg,

good to hear that there is at least one device which throws no error. Could you please send me your test app and perhaps also your source code. I sent you a private message with my email address.

so long ...

Re: Use android device as remote for the WII

Greg — Sun, 06 Mar 2011 00:16:34 +0100

I have tried a variety of ROMs, including a nightly build of CM7. The only device that did not throw an exception on binding the server socket was a stock Evo 4G. Surprising considering that HTC devices are supposed to have crappy bluetooth support. Of course all my test all does is open and bind the socket. I have yet to make a connection to the Wii. And since the Evo was not mine, I can't develop with it. I'll keep installing my test app on devices and see if any others look promising. I'm also waiting for a stable build of CM7.

Re: Use android device as remote for the WII

Hi Greg,

I found a reference (http://code.google.com/p/android/issues/detail?id=719) to an app (http://d.hatena.ne.jp/esmasui/20100330/1269982062) which is supposed to apply a working workaround to bind L2CAP sockets. Also the whole sourcecode is provided. I am not that much into java programming that I understand it but perhaps you could have a look. Would be awesome if that would help our cause.

Here is another link to a zip with the source [db.tt] .

so long...

EDIT: Regretfully it seems that this method is also only for client sockets and not for server ones.
