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.

I'm just hoping for an adapter box that outputs HDMI.

Looks like the Galaxy SIII is going to beat us to it.

Can't wait to see the first demos of it. Perhaps it's like with iphone.

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.

Bluetooth 4.0 Low Energy and NFC?

I've been hearing great stuff about Bluetooth 4.0 LE ((B)LE), like paring heart-rate sports gear almost without battery draining.
Afaik Bluetooth 4.0 doesn't necessarily mean LE functionality, and the only mention thus far I could find was APT-X is included.
Right now I'm confused on whether or not this is supported on the One X. Does anyone know?
Here's a link with a chart that should explain compatibility between new Bluetooth devices, but I really don't get it
And what about NFC implementation? I haven't seen any mention of Sense 4 using it, while Sony's Experia S has those coins with nice software implementation to let the phone know it's next to your bed and needs to be quiet, is in your car and needs navigation etc.

http://www.cellular-news.com/story/53379.php
According to this site it is Smart Ready. As I understand it: It should be ready for the LE-devices.
NFC ist atleast in the Settings:
Look at 2:40: http://www.youtube.com/watch?v=a-478p9v7T8

Thanks for those links Noneus! Seems like the device is BLE ready while Android 4.0.3 isn't. I really hope xda devs can help with this into the One X roms, however, I guess the wait is for nvidia to update their drivers mostly right?

Not necessarily. Most of the time the OS is lacking the Bluetooth features. Not the driver.
Here is a good diagram: https://sites.google.com/a/android.com/opensource/projects/bluetooth-faq
From http://developer.android.com/sdk/android-4.0-highlights.html :
Android 4.0 also introduces built-in support for connecting to Bluetooth Health Device Profile (HDP) devices. With support from third-party apps, users can connect to wireless medical devices and sensors in hospitals, fitness centers, homes, and elsewhere.

Any chance we might see an FM radio tuner app for nexus 7 ?

According to here: http://www.ubmtechinsights.com/google-nexus-7-teardown/ there is an
AzureWave AW-NH665 chip which is endowed with an FM radio tuner. It would be really awesome if some talented soul could develop an app for that!

It depends on whether or not the bcm4330 chip actually sends power to that module. I haven't seen that module fire up in dmesg. That could mean that we simply need a driver for it. The fm framework is already out there. I'm not really a hardware guy but just some thoughts.

On another note, I have been playing with Samsung & HTC modules & drivers for the 4330 (Vivid & Captivate Glide) & I am getting 5Ghz wireless-n working sporadically. Just as HTC has added the capability to newer roms, it would also be possible for it to be supported quite easily by Asus as well. Would be great for streaming.

I would love to see this as I'm sure many would who wish to use the FM Radio for and N7 in a car install, I would gladly pay into double figures for this feature, any devs wishing to take it up there is a big market for getting fm radio working on the n7, do it and watch the £££ fly in ........

I doubt if a driver without an antenna would work - and I saw no sign of an FM antenna in the teardown.
5GHz support would be sweet... Antique adapters in the house really keep me speed limited on 2.4GHz (54MBS)..

That really sucks about the antenna. sometimes I like to listen to the football games out in the yard. Guess I'll have to use my phone.

I think perhaps the most definitive answer to this would be from Mike Reed, who I believe has a Nexus 7 and is also the author of the Spirit FM app. In this post it looks like he thinks it'll never happen.
Too bad... I use the FM Tuner in my phone all the time as well.

I just use Tunein Radio Pro. Was a FAOTD on Amazon. Used the free version before that. Gets the local stations I like...

Exactly. We got a hurricane bearing down on us right now. The last time this happened, We were without power for 3 weeks, and 3g was a laughable dream because all the cell towers were down. We NEED FM radio.

Your Nexus battery isn't going to last 3 days. If this is for disaster situations, just get a regular FM radio or one of the ones where you can power it with a hand crank. Either way we don't NEED to have FM on the N7. It would just be a nice perk.

Most mobile devices utilize a headset as the antenna. I wonder if this could be as simple as porting a FM tuner app from a device that has the same chip set with working FM tuner app?
Sent from my Nexus 7 using Tapatalk 2

I was wondering if anyone had any success? I was thinking about integrating a Nexus 7 as a car stereo replacement. Mount it in the dash (trimmed to make my GM Double DIN space a little wider), and route a line out into an EQ, which then would feed into a couple amps. ~$50 for a used 7-11 band EQ, ~$200 for the Nexus = a pretty kick butt deck if you don't need CD. But I would still like FM for traffic, news, games, radio contests, etc....

Last time I checked there need not be an internal FM antenna, most devices with tuners in them actually use the ground lead of your headphones. This is also why radio apps often fail without headphones or powered speakers attached.

Lol, are you serious? I don't know about you but I had my N7 under clocked at 900mHz with WiFi on, bluetooth off, and display all the way down, and I got a week on my battery. A Nexus 7 is a tank when it comes to battery you could EASILY get 3 days off a N7 battery.

You can have FM on your Nexus 7 now
Just get one of those cheapy RTL2832U based USB DVB-T dongles (they can be as low as £5.60 from eBay - http://www.ebay.co.uk/sch/i.html?LH_BIN=1&_fcid=3&_sacat=0&_from=R40&_clu=2&_nkw=RTL2832U&_sop=2)
Then download SDR Touch - https://play.google.com/store/apps/details?id=marto.androsdr
You don't even need to root your Nexus 7.
You might want to have a powered USB OTG cable in order to make it last for longer, since the tuner and the SDR decoding on the CPU is quite a battery eater. Another downside is that you can't charge your tablet while having something plugged in the USB port.
FM Stereo and even possibly RDS are features that will appear in SDR Touch soon enough
An added bonus is that you can now also listen to police frequencies or analogue TV sound while you drive as well

[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.

Thanks, I am personally waiting for these devices (StickNFind, BluTracker) to hit the market in March and April respectively and I more and more inclining to get an iPhone because of the better support there. For Newtonfb, did you look at BodyMedia FIT LINK Armband? This is what I use and it has all the same features plus more of Fitbit and is fully supported on GNEX via regular Bluetooth.

I'll look into that. Thanks.

Apparently the issue is not with the chip, it's with the kernel. In order to have BLE you need to have the kernel bumped up to 3.4. From what I've read there are instability issues on the GNex with 3.4, possibly due to the fact that TI isn't doing anymore work on the OMAP processor line. So unless google figures out a way to release a stable, then we're out of luck. Or if a kernel developer figures out a way, but from what I understand it's a bit of an undertaking to accomplish.

Is it possible for the debs to actually make it work. If it's I would jump on that.

Hmm... I hadn't heard any of that info. I guess I just assumed that any devices that have BT 4.0 hardware, and get a 4.3 update, would support BLE. When you are saying 3.4, I assume you mean 4.3? Don't the new stock 4.3 images for the nexus devices come with an updated kernel for 4.3? Hopefully this gets worked out...
Ah... I know what you mean by 3.4 now... You are referring to the kernel version.

There is always a weak link, if the OMAP is really not compatible with Kernel 3.4 then it'll be very hard if not impossible for the devs to fix....

Well, that was my speculation earlier in the thread :]. Thing is that a module could be included in whatever kernel there is. Google Glass for instance uses the same chip and CPU as GN, but was certified for BT 2.1 only in April. Why are they're not bringing BLE on there is a mystery, because it's certainly a type of device which would benefit a lot from that functionality.
It may also be that Broadcom doesn't release the proper support for it. Chip vendors can be show stoppers because of politics (they develop new chips all the time, remember).
