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.

[Q] Micro USB to Ethernet Port Adapter for Galaxy note 2

Just wondering if there anything out there that would work? Is there drivers within Jelly bean that would allow me to do this? Any help would be appreciated.

Could you use a otg cable and a normal usb to ethernet adapter? Don't know if something like this is supported though.

But why u want something like that while u have wifi and kies air? What thinga u canot do through wifi?

I don't want to use WiFi because i don't. Simple as that.
Have anyone found something to solve this problem?

Yeah,
That would be a welcome feature if possible. Can't get wifi everywhere.

Yea, I just tried it right now as I just received my usb-on-the-go and did not work. Its the same usb to ethernet dongle that I've used on my Transformer. (http://www.amazon.com/gp/product/B003VSTDFG)
I am hopefully getting the dock for this thing and wanted to use this as a full blown computer with ethernet. Hopefully someone can get it to work.

It might work but might have to be built right in the kernel...hmmm...looks interesting though.

My Note 2 will actually light up the USB Ethernet adapter and show a link to the network switch, but there doesn't seem to be any 'Ethernet' connection usage option with the Note 2 as of yet. I was under the impression by default Ethernet functionality was part of ice cream sandwich and jelly bean, but it appears Samsung has removed it.

My experience has been exactly the opposite. Most Android kernels (and almost all stock ones) do not come with drivers that support most Ethernet chipsets, even kernels that support OTG. While these drivers are usually easy to find in Linux source code, very few flashable kernels compile them in (It's not hard if the kernel builder chooses to include them in the build tree).
I have two inexpensive USB Ethernet dongles and have had a very hard time making either work. While waiting, I have resorted to getting a small traveller's portable Ethernet hotspot/router such as the TP-Link WR3020. That works fine and has the benefit of supporting multiple devices off one Ethernet drop without needing a switch.

There are still many hotels and offices that use wired Ethernet and don't have wifi. So if you want to replace a laptop with an N2, sometimes you need to be places where there is an Ethernet drop, but no wifi (and either your SIM card doesn't work where you are, or roaming is horrendously expensive).
If you travel frequently, it can happen often enough that you need either an Ethernet network adaptor, or a small wifi router.
Also: even if not travelling, you can't break into a wired connection quite as easily as a wireless one. Wired is often faster and certainly more secure.

I need this Ethernet-over-USB functionality. I believe it is called CDC-ECM. When I have built a Linux kernel in the past it was included with option "Multi-purpose USB Networking Framework"
Does anyone know of a kernel for Note2 (N7100) that supports this?

I asked the same question. http://forum.xda-developers.com/showthread.php?t=2115186&highlight=ethernet
And no one answered. I need this functionality too. It seems nobody can help.
It`s only way to ask ROM builder to add these features to their products, i think.

up for this thread.. i need this functionality also

To confirm the above:
Yearsterday I received USB to RJ45 LAN Ethernet HUB internet Adapter (ebay.com/itm/USB-to-RJ45-LAN-Ethernet-HUB-internet-Adapter-for-google-Android-Tablet-pad-Tab-/250894821624)
It does not work with my Note 2 (GT-N7100, Omega v12 - XXDMB2), although it works great with ASUS PadFone2 and with desktop (windows7 64).

Micro USB to Ethernet Port Adapter for Galaxy note 2
Hi folks
usb to ethernet seems to work on Android for some, I guess hardware and operating system (embedded drivers?) have to match this device
For my Asus Transformer I can use their ethernet adapter by simply plug it in.
On my Samsung Note 2 JB 4.1 nothing happens...
Would rooting help?
Anyone managed to have it work?
I know that wifi is a much easier method but it's good to know it doesn't work on this device :laugh:
Sorry for my bad english, I'll try to improve
these items works on the Transformer with JB 4.1

I don't understand people, who think: if i don't need it, nobody need it.
I bought note to use it on work. Ideally it should be used instead of a laptop.
The problem is that I am not allowed, for safety reasons, to use wireless link.
And actually it interesting to make it work.
But thanks for the tip, in other way it can be useful.

As discussed above it did not work with N2.
I think Renthal (message #8) and el56 (message #9) are right.
We need kernel for Note2 (N7100) that supports this feature.
But still nobody has found the ROM or Kernel for GT-N7100, which correctly work with USB Ethernet adapter.
Only root will not help.

I have a second device, a Nexus 7, which (unlike my N2) is rooted. The stock kernel in the Nexus 7 does not support Ethernet-over-USB, and many third-party kernels also do not. However, I did find one kernel -- "Bricked" -- that did. Since installing that kernel, that device now works very well over wired using a $2 OTG cable and a $4 USB Ethernet adaptor (both bought on eBay)
(That setup actually worked in a real-world situation - a hotel in Beijing, that has only wired Internet - in which a Wifi Ethernet router didn't work because of post-connection login requirements.)
This experiences confirms the contention that the drivers for Ethernet-over USB are *available* for Android kernels, but that stock kernels (and most auxilliary ones) have chosen not to implement them. The answer for Note 2 users is to convince Samsung (or, more likely, custom kernel builders) to enable Ethernet drivers that already exist.

I remember seeing patches for Honeycomb stock kernels for numerous devices that add alot of drivers. It maybe feasible to compile the kernel modules and insmod them, if we have kernel sources. Do we have them? Hellllllooooo?!
And I'd like to have this functionality. To all people wondering why one would need to use such *cough* ancient *cough* technology as wires:
At my workplace there is no 3G coverage (hell, it struggles to connect to EDGE, falling back to GPRS, voice calls also suck), and we're not allowed to use any kind of WiFi or Bluetooth or any other radio, including wireless mouse/keyboards (corporate industrial network sucks all the channels, anyway), but we're supplied with wired, unfiltered network going straight to internet, just for sake of having internet on our devices (my work consists of cycles 1-2 hours of intense coding, and 1-2 hours of empty waiting for tests), so we won't get bored to death. So.... I want my ethernet dongle working! http://freeware.info.pl/software.html

Yeah, I really need that feature too.
I have 2 young daugthers and my wife doesn't want to hear about wifi or 3G at home, cause of health concerns.
And in addition, I work in a company where wireless connections are not allowed for security reasons.
So Ethernet connection through USB adaptateur is almost the only option for me.
But isn't it possible to install drivers on an androids smartphone, as we usually do on PC ?
(Sorry for the newb question)

Thanks. The reason I ask is that I saw this on Wikipedia. It states that it is Bluetooth 4.0 hardware compatible. 2nd reason is I bought those Bluetooth speakers with Bluetooth 4 and apt-x support. I just want to maximize it to it's full potential.

Wait wait wait, one moment, i don't understand. The hardware inside GNeX is bt4 but it has driver that doesn't support that but only bt3, is this what are you saying? It sound really strange to me, maybe that statement on wiki means that GNeX can use other hardware with bt4 even if it's bt3 but not at full power, am i wrong?

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?

Do I have issues with my 10.1-2014?

Hi all, I have had my P600 since Christmas and it has been good. I am running ML1 firmware, no root. It shipped with MJ2.
I have noticed a couple of problems. Firstly, I have occasional bluetooth keyboard disconnects. They really infrequent but definitely occur. They just don't seem to be anywhere near as severe as people have been describing in other threads.
Secondly, this tablet just can't detect my 5GHz wifi connection. My Note II on the table next to it has no problems finding and using that connection. I am downloading MK1 firmware now to see if it is ML1 that is the problem, as I *think* that the tablet originally detected both 2.4 and 5GHz connections. I didn't really take note though. I have noticed this now mainly because I've been trying to turn wifi on and off to test what may be happening with bluetooth.
Thing is, I've never really had a good BT experience in my life, but I need to get this keyboard and a mouse working to use this tablet the way I intend to.
Is the 5GHz failure an ML1 thing, is there some other cause, or is it a hardware fault? Any tips?
Cheers,
Jason

Running ML1 as well. No comment on the BT keyboard since I haven't used mine enough yet, only for a few minutes here and there to test, not long time.
I have a dual band Asus RT AC-66U and I can use both my 2.4 and 5 Ghz networks. Only thing is that the 5 Ghz network gets poor reception from the tablet across my house (to be expected I suppose).

Thanks for the reply. It prompted me to look further and I realised it's a channels thing. Changed the channel on my router and the Note can see 5GHz now.

I agree. It is stressing me out. I feel a little trapped because a good test would be to install cleanrom 1.1, which at least one person has said fixed bluetooth, but I can't do that without sacrificing my warranty.
I am not even sure whether I have a hardware problem or bluetooth is just a dubious technology.

Hardware difference between FLO and DEB

I have been searching for a teardown of DEB but cannot seem to find one. Does anyone know the differences in the hardware between FLO and DEB besides the obvious, one has a sim card and one doesnt.
Is the LTE capability integrated into the SoC on DEB but not FLO? If not, is the LTE chip located on the main board with the SoC or is it on the daughter board at the bottom of the tablet where the sim-card plugs in? Any help is appreciated.

It's my understanding that Deb is relatively the same as Flo with the exception of data and full GPS capabilities. Many have flashed Flo ROM's on Deb devices and they will work but will not have data and full GPS capabilities, which defeats the purpose of having a Deb. An actual Deb teardown I have not done though.

I don't remember seeing it anywhere, but can I flash Deb roms on my flo? Theoretically, it should be fully functional (the flo, that is...), but I haven't had the guts to try as yet.

I don't actually care to try...I was just curious. Curiosity isn't enough of a reason for me to run that risk.

I've flashed deb roms onto my flo in the course of doing testing: yes it will flash and boot fine.
I forget if it would work without bugs (testing mainly consisted of making sure it boots and nothing major is broken, like wifi, screen, or touch)
Obviously you wont magically get cellular support, it'll be like how it already is: the rom will simply see a radio that cannot connect/sense any type of network.
The biggest hardware difference is obviously the lack of the modem, it's an external module like on all S600 devices.
Software wise there isnt that much major differences:
They use the same bootloader
They use the same kernels
At launch they had the same basebands (flo's never gets updated though info on wiki)
The actual drivers and roms are not identical though, at the very least they're built in both 'deb' and 'flo' configurations, at the very least they have different names inside the drivers

My experience is that some ROMs will work between the "Deb" and "Flo" models but others won't. Some are even advertised as being bisexual. :silly:
It's entirely possible for the hardware on both models to be exactly the same, with some deeply rooted firmware switch to activate LTE. I'd think from a manufacturing and inventory management point of view, it'd be cheaper to build one version due to less tooling and inventory holding costs.

Regardless of if the modem is in flo or not, there's no sim card tray on flos.
They could hypothetically use deb boards that otherwise work 100%, except somehow recieved a faulty modem chip,
but without a sim tray you wouldnt be able to do much with just that.
Many old tegra 2 based tablets had a PCI-E mini slot (PCI-E mini can do either PCI-E and/or usb, only the latter was actually available and that was what was used) where the modem went, you could likely solder in a slot on the wifi model and get the same modem elsewhere, but you'd need to also get a sim slot and tray to actually make it useful.
