Wifi Display will be coming to Galaxy Nexus

Many of the people who had been wondering why Google chose to go with the OMAP 4460 as the processor for the Galaxy Nexus have gotten yet another answer to that question. The Omap4 series of processors are compatible with wifi display. as of right now, besides the Omap4 family the Snapdragon S4 is the only mentioned to be getting wifi display. It looks as if the Tegra 3 isn't going to support it at all according to http://www.androidauthority.com/wifi-display-to-make-your-life-easier-in-2012-47153/ . At this time it looks as though the OMAP4 is going to be the only current gen chip that will support wifi display, and of course with us having a nexus device we will most likely be seeing that update before anybody.

No problem. According to the androidandme article we're looking at a summer release. I am looking forward to this coming to our phones as I think it would be very useful for me. Often times I'll either connect a laptop to the TV or my cell phone and stream kid's shows from a particular site for my son. It would be very nice if I could do that without having to connect my phone directly to the television like I've been doing. I could sit across the room on my computer while he watches his show and still have my phone right next to me. That would be nice.

Is this WiDi?

From what I understand (and I could be wrong, so anyone correct me if I am) widi is an intel thing and it's for displaying your pc wirelessly to a television. Wifi display involves a "wifi direct" connection between two devices and is actually an emerging standard that the wifi alliance is backing. All in all I don't think it is the same thing was WiDi.

But we need tv that support this wifi display?
I don't have such tv.

That or just an adapter. Also, from my understanding it works with computers too, and any other wifi display capable device (not sure what other devices that would be).

Maybe it will work better than WiFi Direct? Has anybody managed to figure this crap out?
Maybe hardware supports it, but I think we will need software to handle this. I'm not sure that there is a permission for app to handle access to wifi radio (and any other hardware needed for this), so it will have to be implemented in the OS...

This technology is much lower latency than Intel WiDi, and it's also not proprietary. WiDi is good only for video, whereas WiFi Display is quick enough to support real-time gaming. And as an open standard that's cheap to implement, you can expect it to kill WiDi in short order.

Connecting two wifi direct devices isn't too difficult. For example, connecting a galaxy s2 to a Galaxy Nexus works fairly easily. That being said, you are right that wifi display will have to be implemented on the OS level. From what I understand they expect an update to come from Google some time this summer that will implement the feature. We've got something to look forward to this summer lol.

Could the WiFi display work two ways, buy a small 10.1" WiFi display with touch screen, connect to the Galaxy Nexus - instant Nexus Tablet!

I was wondering the exact same thing! That would be great if that turns out to be possible. There seems to be several different possible applications for this. I'm excited to see what the community comes up with for this.
Something off the top of my head is: Having software installed on the computer to remotely control the phone. Create a nfc tag that starts up wifi display to your tv and launches the computer remote controls. When you place the phone on the tag you will instantly be able to control the phone via the computer and have it displayed on the television. That's just an idea that came to my mind.

This is why i got a nexus

Is there any word on when we might be receiving this?

What I want to know is when we will see the technology on the TV side. Google updating doesn't do much good until we have devices to pair with.
On another note, I'd have trouble justifying purchase of a toggle or $4000 flagship Sony TV exclusively for this functionality. I wonder if we will see this technology utilized in entry-level smart tvs or rokus, google tvs, and xboxes. This feature will really become useful when it is available on most any wifi-connected display around you.

The demos from Texas Instruments I saw looked more appealing than the iPhone's method to me. The latency is also suppose to be much lower. I'm excited, that was the one feature of the iOS ecosystem I was very jealous of.

This is somewhat OT, but Samsung is also releasing a set of cameras with built-in WiFi direct capability. Your phone basically becomes a remote control/viewfinder for the camera and you can control most of its functions. I love where this technology is going.

[REQ] Kernel: usbaudio.o

is this what you are looking for? I can make that happen...
Audio Gadget (EXPERIMENTAL) (USB_AUDIO)
CONFIG_USB_AUDIO:
Gadget Audio is compatible with USB Audio Class specification 1.0.
It will include at least one AudioControl interface, zero or more
AudioStream interface and zero or more MIDIStream interface.
Gadget Audio will use on-board ALSA (CONFIG_SND) audio card to
playback or capture audio stream.
Say "y" to link the driver statically, or "m" to build a
dynamically linked module called "g_audio".

This migth be a noob question but what exactly dose this do?
Sent from my SGH-T989D using XDA

To put it simply, a usbaudio.o addition would allow USB host to recognize a generic USB audio device, be it a set of USB speakers, USB car audio, USB sound card or USB headsets.
A few reasons for wanting such a thing would be that you would:
1. Bypass internal sound amplification and digital-analog conversion, so you get cleaner sound if you have the gears to support it,
2. Use USB headsets, speakers, car audio and whatnot, the same way that you would've used them for Win/Mac PCs, now on your phone,
3. Not having to be tied down to the single 3.5mm output as you can now hook your phone to a USB sound card that can get optical out even, and this is more portable than doing so with a laptop or having to resort to a dedicated music player.
@thederekjay: I'd be really grateful if you can implement this in your kernel man. Cyanogenmod 7/9 seem to have this prepackaged, but you can't exactly take Cyanogenmod kernel and slap any random rom on it.

Yep, the big thing that makes me want it is greatly improved sound quality. The Yamaha chip in the T989/Skyrocket is pretty bad, even supercurio (Voodoo Sound) won't touch it. Turning my phone into an über music player will allow me to easily use things like Pandora and the upcoming official BBE player (currently only available on iOS, but I talked to a developer and he said it'll be coming in late spring/early summer for Android devices) while maintaining audiophile-grade sound quality. For a completely portable solution I have the Fiio E7 amp which has built-in USB audio and doesn't drain power from the connection (a workaround for devices that do require power from the USB connection is to use a powered USB hub in-between). However, with this feature you could just as well hook it up to a $10,000 sound system that has driverless USB audio and *still* have audiophile-grade sound quality because it's a purely digital signal.

Now that the T989 ICS source has been leaked I just wanted to remind developers to please consider adding this in. Thanks!

Android 2.2 6,5" CAR Device
There is an Android 2.2 800Mhz 256MB 8GB 6,2" TFT CAR DVD on sale (800 USD to door in Russia) that I have bought recently and after some software installations it does deliver what I have wanted to have in the car.
Nevertheless there are a few major complaints to its performance: http://www.youtube.com/watch?v=cx53a6N7_ws
As well there are several other minor things that would be great to change if possible.
If there is someone interested and able to cook a custom ROM for this device - I can send this device for free as a gift and for experiments. We really want a good ROM for this CA-Fi Car Stereo and the guy's in China don't seem caring enough.
I will check this thread once in a while and provide contact details for anyone interested in developing this device. It is very close to being a great thing for a CAR!
I have updated my email in the XDA profile so you can as well use this option to contact me.
PS
I Have a ROM update file (192MB) that came from the device vendor (dealer). I can send it out for revision.
The way to install this rom on the car stereo is to extract files to the root of a microSD card, insert it, switch off the device, then, while holding the screen tapped, power on – the device starts an install mode. When finished it asks for screen calibration and restarts with a new rom as after a hard reset (erases everything).

And there is the Parrot as well.

i've gone down the route of car pc etc, it was running win 7.
to be honest, they're wayyy to much fuss and aggro.
the sound quality sucked, the screen was **** (it was cheap - £250 "cheap") and broke shortly after a year of having it.
a decent head unit, with either apt x bluetooth dongle plugged in, or just the 3.5mm with hox is much much better. sound quality is way better, and i don't have to put up with some slow 800mhz cpu when all i want is to be driving whilst listening to music
just a fyi for those considering, its a huge cost, for not actually that much benefit (unless you live in your car)

CA-Fi Android Car Radio
I understand you if you only need to have music playing while driving, as well as some people who still prefer using monochrome cell phones. This is a matter of needs.
Regarding the sound quality of this particular CA-Fi device its surprisingly fine. I use its 4x45W out lines conneted directly to car OEM speakers (its a Chrysler PT) and the subwoofer RCA out channel connected via a 1KW Kenwood amplifier to a large Polk Audio woofer. With the available in this device GEQ and Bass/Treble settings the unit provides perfectly sharp and clear sound in the high+mid ranges for the OEM speakers that in company with the powerful sub make a really impressive rich and clear sound scene with no distortion at any volume.
This sound setup is very easy and efficient. Honestly, to my hearing it is not lacking comparing to my previous JVC Mosfet 192/24 DAC car stereo that was routed through amplifiers for all channels to Focal speakers instead of the OEM... That was too much trouble for the gained advantage. Again, depending on the needs. Trully - the sound of this Android Radio is fine, a sound of a branded Hi-Fi car stereo.
And if you had a Win7 Car PC setup that is quite complicated to arrange you should agree that this easy one-box Android PC solution is a great idea. It provides the music and all the tablet PC advantages. It's really nice after switching on the ignition to hear from your car that you have a new e-mail arrived, and enjoy other goodies like that.

yes, I considered the Parrot, but found it limited for modifications and with a too small screen. There is as well a Clarion at present under development, but it does not appeal to me neither. It is a concept from the Clarion Malaysia division and most likely will be limited for modifications; if it will ever be released at all:
http://www.youtube.com/watch?v=xNQC56S5NFI
http://www.youtube.com/watch?v=N1TFiy2Dsdg
I really have spent some plenty of time on the web before selecting this CA-Fi device and I couldnt find anything better. To be honest I even went trough a mistake and loss of money by ordering an Android/WinCE dual OS device first (by the way its refferted to above in this thread). Result - I installed it into my dad's car (its better than his OEM 2003 Mercedes device anyway). But that one is wierd. My advice: be aware not to get one of those by mistake. For example, mine had GPS only in WinCE and 3G only in Android - so I couldnt have the Navigation system working along with traffic updates.... this spoiled everything for me.
PS
Important to know that CA-Fi offer a few dozens of versions of the same model with different front panels to match many of original car dashboards without the need of modifying the panels - the device fits in as a replacement for the OEM unit! As well for those who think that there are many different Android car stereos to choose from - this may be the same model with different front facing.
Like theese are the same device:

It'll be clearer if you check out the link in my previous post. Gnex contains a Samsung SWB-B42 BT 4.0 Dual Band Wlan FM Tx/Rx chip so the hardware is there. The thing is the driver that is currently installed on our gnex only has BT3 coded in. And even if the driver utilizes the phone's BT4.0 capabilities, Android in itself doesn't have native APIs to allow developers to take advantage of the new features.

Sorry if i didn't read the whole link but i was at work so, you can understand... Thank you for the very clear explanation, however it's really really strange this behaviour by google...

Will Google/Android ever get BT4/BLE working on the GNex? Or shall we move on to another device if we need/want it?

[Q] What is the state of Bluetooth Low Energy support for Galaxy Nexus GSM?

I remember reading sometime back that Galaxy Nexus has hardware capable of supporting both Bluetooth 4.0 stacks, but that BLE (Low Energy profile) was not enabled via driver/SDK. I wonder if there was any progress in this direction or at least clear indication from Google on the support. There is a binder full of BLE devices getting on the market in Q1 that jump on support from iPhone 5 and some of them are extremely attracting but I would hate to get rid of my Nexus if I could.
Is there a ROM that can provide compatibility?

Ive been trying to post everywhere and anywhere about this topic but noone seems to care. More and more devices are being launched use BLE and developers wont make an android app because android doesn't support BLE at the moment. I dont know why more websites are making this an issue yet..phones are being launched saying they are 4.0 capable..which is correct but we cant use that technology. Its sad because i want the new FITBIT flex band but they are only making the app available to sync with the S3 and note 2 because samsung is helping then with the Bluetooth drivers for the app.

In addition to your post, a ton of devices are coming with AVRCP 1.3+ on stock devices. However only a select few ROMs have it enabled at all.
