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] 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).

I don't understand peoples who make things more complicated that can be...when u can find so many small wifi router even with mobile battery.in a wire LESS world u want to use meters of wires for what?it's a mobile phone not a desktop pc with so many wires.

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)

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?

[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.
