Hi guys,
Yesterday I was thinking about how to enable the NFC sgs2 not have this technology, so I thought that using bluetooth or wifi direct you might also enable nfc
Android is not a developer so I need someone who can create a program that "hijack"the signals that are transmitted via the nfc nfc chip to an external device via bluetooth or wifi direct, then I did this I will create a hardware device composed of the NFC chip and a receiver / transmitter bluetooth or wifi direct to hide behind the battery, you will be able to receive the signal and then sending it to the NFC chip.
Does anyone know how to help me?, I am completely new in the Android paronama.
I think nfc is a magnetic signal, very different from BT, or wifi, so I think this idea would take a whole notha level of brilliance to actual make happen

It should be possible in the future to use NFC with an SD-Card that has NFC integrated. I think a diy is fun, but possible more expensive due to your bt solution.
are we sure nfc is not inside first sgs2 ? how to check ? Maybe it can be activated in few times.....
NFC is very similar to wifi, and also by bluetooth it to communicate using a wireless frequency.
however, what is the story of the NFC in the sd card?
I really don't think its worth the effort involved. Reminds me of someone I know who spent thousands trying to make his bmw 318 into an m3. When he finished, it looked ****e, didn't work properly and could have bought an actual M3 with the money he spent. Sorry to put a downer on this.
There is no NFC in the Sgs2. Als new Sgs2 has been announced with tiny improvements and NFC os included.

You would be better with SIM based NFC tbh... You can't just randomly say "let's use wifi/bluetooth instead of NFC, as they both work on radio waves of some sort"
I still want to use the wifi / bluetooth nfc only to transfer the signal to an external hardware that transmits, via the receiver wifi / bluetooth, nfc signal to a transmitter.
the idea and the hardware is easy to do, but the software ... I do not know, but I think it's tough.
at least someone can tell me of the nfc in the SD card?
Just buy an nfc enabled phone if you want it that badly. Trust me, trying to do a DIY job will bea waste of your time and money and will all end in tears. LOL.
i'm not sure if it's asking this'd be dumb but how would i understand if i got nfc şn my phone? i bought my sgs2 yesterday but it's still grey market here in Turkey so i can't be sure if i got nfc or not..
NFC sticker can make SGS2 NFC enabled..

Wow, it's amazing how many people post without reading the first post where OP clearly states he wants to create a device that reads NFC and then transmits it to the phone via bluetooth or wifi :

Also, using an NFC sticker is not the same : It will enable you to use your phone as a payment or transport card, but it won't allow your phone to actually READ NFC tags and display some information, nor REWRITE NFC tags.
Anyway, I think it's a good idea but probably not worth your time and money with NFC enabled Galaxy S2 coming in a few weeks or months. Besides, even if my SGS2 doesn't have NFC, I'll probably have a new phone in 18 months or so when NFC becomes really useful.

Agreed here. Surely the most used function of NFC will be for payments until other phones catch up, and this is accomplished by a sticker anyway?
I'm all for modding and hacking, obviously, but I feel that it may just be needless in this case...

Anyone got the userspace nfc stuff, either from korean model, or the nexus s? That chip is the same as in the N S
not every model have the NFC chip on them samsung did say that some already do have it and they just need a software upgrade to enable it but i know none of the UK models have a NFC chip. Samsung also said that the one with it are slightly thicker phones than the ones with out it...
microsd nfc cards
Didn't someone mention here that Samsung had stated NFC was on the battery in enabled models.
Could it be one of the options here http://smartsim.info/products.html
Item 2 - special battery combined with carrier provided sim could mean even reader mode is possible retrospectively for a fairly nominal charge
At least for normal batteries. I now have 2 std 1650 batteries, a mugen 3200 and eyes on the new 2000 mAh options . Yikes.
Great News for the normal SGS 2 Users.
I just got an S3 and I'd like to ask if it is possible to listen to FM radio over Bluetooth.
i connect the standard headphones to enable the FM radio and the only option is to switch output between the headphones and the loud speaker.
I've seen cheap chinese android phones doing that, there should be a way.
Any help would be greatly appreciated, help me avoid selling my new toy
Sorry to say but it won't work. The reason (as the app itself already accurately describes in the error message) is that your headphone's cables are used as an antenna for the phone's FM receiver.
FM antenna's are actually quite big (at least compared to other antennas) even when using the so-called fractal design because they use a very slow (roughly 80 - 110 MHz, compared to e.g. WIFI's 2400MHz) frequency. To save space, Samsung moves them to the hedphones on all mobile phones I know of.
I don't know if it still works on S3 (never tried) but on the S1, if the station is broadcasting with enough signal strength, you could cut off the plug of old broken headphones and plug it into the phone to use the radio.
Afaik Spirit FM (now paid in all versions) can override the requirement but you'll need to press your finger to the jack so you can receive anything... pointless.
Alternatively you could use an app for internet radio such as TuneIn; most radio stations (at least all around here) provide web-streams for on-the-go radio listening. However you should make sure you got a decent internet flatrate, I managed to chew through nearly 4GB just with music streaming this month.
Most countries seem to have abolished mobile data flatrates.

The OP understands that the phone needs the cord to act as an antenna. I think what they simply want to know is if the phone can then route the sound to the bluetooth device instead of through the speakerphone or the headphones.
Sent from my MB860 using XDA
d4fseeker I understand that the headphones should be connected since they serve as fm antenna. What i want is to listen to fm stations through bluetooth while the headphones are connected as bigb25 says.
TuneIn is not a solution for me since some stations I want are not available and cause I am a hiker internet is not always available where I go.
Maybe there is a fix or a different radio fm app?
OK quick test... plugged in 3.5mm - 3.5mm jack lead into headphone socket to act as the FM antenna and started the radio, selected sound to speaker and all worked fine. switched on Bluetooth headset no sound in headset, switched off sound to speakers still couldn't hear anything. Unplugged patch lead (this ends radio anyway) played an mp3from music player and sound returned to BT headset.
So unfortunately the answer is no you can't, as soon as you plug the anything into the headphone jack it cuts out the sound to any other device.
This may well be a mechanical switch within the headphone socket and so unlikely that there's a get around in a custom rom....but then I know nothing about roms

The latest Free version of Spirit can always be found at the top of post 1 of my Q&A thread. See my sig.
My cheapest ($80) test phone gets good audio AND RDS with no antenna. Ironically it's the best of 12 operational test phones I have. It's a Samsung GT-i5500 with the great, sensitive new Broadcom 4330/20780 family of chips.
But yeah, my Galaxy S and S2 don't do very well with no antenna. My Galaxy Note does better. Haven't heard from anyone with an S3 yet. They all have the Si4709 FM chip, which has positives and negatives. Internal circuitry etc. makes a difference too.
And I can thank the very positive sales response I've had from S2 and Note owners for being able to buy these expensive devices for testing. I'll do everything I can to make Spirit run well on S3 and hope to buy one soon.
I have yet to find a phone that does FM over BT, except for a strange very low quality mode I have working on some BCM 4325 based devices.
If the FM can be done in the digital domain, instead of the more common analog, then in theory it should be possible to do FM over BT.
But then again, in theory the Galaxy S and S2 hardware are capable of FM record (digital). Yet the audio libraries don't seem to support it, and I think it'd be a major/infeasible job to hack the libraries for it.
The Note and I think the S3 can do FM record with stock audio libraries. So I think FM over BT on these devices is feasible, at least with stock ROMs and/or using stock libraries.
But on non-stock ROMs like CM9, the Note seems incapable of FM record.
Basically, if the stock ROM and stock FM app don't support FM over BT, then I think it's not EASILY possible.
If it could be made to work, there's no reason why a phone couldn't have a wired earphone plugged in at the same time that FM goes over BT. This might "confuse" the audio system though, which usually sends audio over a wired headset if one is plugged.
Then again, it's also possible to have a plug that's partly inserted (or maybe even wired creatively). Enough for antenna but not enough to push audio through the wired headset.
Thanks mikereidis.
I tried the free version, it plays only when the headphones are connected.
Do you think you could look at the possibility to send output to bluetooth?

A colleague has it and I tried it just now and the quality is superb. And it is much cheaper comparing to the 730 Euro I gave to buy the SIII (greek retail price 32 GB version)
Actually this was the reason I switched from IOS to Android I mistakenly thought it was a default option in Android.
Also my ancient HTC diamond could do it with the help of a bluetooth utility but it woud often crash and quality was not good.

I have one person reporting success with my app on GS3 on CM9 June 19 now.
It only works one time though, then requires a reboot for the 2nd time.
This was with an experimental release I haven't made public yet.
I hope GS3's will be coming down at least $100 over the next month. $700 is pretty darn steep, even if it's got a leg up on the One X and One XL I bought recently for 570 and 500.

That's very interesting; thanks for the info.
There are a variety of relatively inexpensive Chinese devices that have unique qualities, such as FM on an Android tablet, or digital TV tuner, or FM transmit I think.
But these devices are not widely available, or popular I think, in most Western countries. Information, source code and custom ROMs can be difficult to impossible to find.
As for Android: the audio systems can be kind of a big complicated mess. I don't think I've ever seen a single phone with an audio balance setting, among other things. But at least some Androids have "over the air" FM, whereas iPhone's have never had FM, despite years of rumors.
i am thinking of using one of these dongles though I doubt about the quality

Kind of a drag to have a dongle hanging off though, in addition to the wired earphone for antenna.
There's been a lot of praise for the Sony MW600 Bluetooth stereo headset with built-in FM the last few years. Under $40 on EBay now.
I just ordered the apparent successor, the MW1 for $120 plus shipping the other day. It even has a music player built in, besides the FM and BT 3.0 support.
I need the A2DP headset because I think I'll be able to support FM over Bluetooth on some devices in the next few months, and I need something to test with.
MW1 seems interesting with many features but the price is ....

Not an exact solution, but you can get bluetooth headsets with built in FM radio.

The headphone jack has a part that senses when a headphone is inserted (the metal
in the headphone plug shorts it. It seems like you could make a plug that connects
to the metal of the ground pin (for the radio antenna) but isn't "inserted" so the phone
won't disable using BT.
Anyways, only i9300 will support FM, there is no way to get FM working with the Broadcom
chip in the US S3's. http://forum.xda-developers.com/showthread.php?p=31576462#post31576462
I use a sony ericson bluetooth headset that has built in fm radio works well.
Model MW600havent priced them in a while,should be under $50 by now.

Hi guys,
i found this in an article:
http://news.cnet.com/8301-1035_3-57389687-94/the-power-of-bluetooth-4.0-itll-change-your-life/
One-tap hookup
Another convenience newer forms of Bluetooth brings is compatibility with NFC chips. Both Bluetooth versions 3.0 and 4.0 can talk to NFC hardware in phones and laptops to make pairing a simple process of tapping the two devices together. So you can imagine configuring Wi-Fi settings on mobile gadgets just by resting them on NFC equipped routers or hooking up headsets with tablets and phones in the same manner. For example, Motorola's new Elite Sliver headset already has this NFC pairing ability. Frankly the idea setting up a gadget this fast gives me goosebumps.
What Exactly does this mean??? can we pair our desire x with NFC phones??
Or am i totally in the wrong direction??

for pairing with nfc devices you need a NFC sensor in the phone which can interact with NFC enables devices like portable speakers or laptops to be put in simple words NFC just removes the troublesome pairing problems in bluetooth or wifi and helps in data transfer via bluetooth or wifi which ever is available and is faster (in most cases its just wifi but relating to this article and practical life Bluetooth also comes in the picture)
hope this clarifies your doubt
I already know what you said. I'm just trying to understand the article. He says Bluetooth 4 can pair with NFC. How ?

Bluetooth devices with A2DP profiles can pair with nfc devices which is seen Bluetooth headsets and speakers usually which is missing in our dx so technically you can't connect with nfc
Edit - tried to pair with my friends xperia p with nfc with A2DP profile from an app failed
I think Bluetooth is just used as a way to trust the NFC partner.

Hi there, it's the first time ever I'm creating a new thread. Pardon me if I mess up. I have two cell phones, one is Nokia 5230 pretty old feature phone which I'm using for the company and my personnal phone, which is a Note 2.
In addition of this, I'm using Sync in my car, obviously.
I'd like to have both phones connected to Sync but that's not possible at the same time. I had an earpiece which did that, but my car doesn't.
Now I'd like to control my Nokia remotely with my Note 2 the same way my Sync controls my Note 2 (place call, answer call, forward the voice). I'd like to use my Nokia only to have a line.
I know computers can do that (I could have my laptop control my Note 2 and getting the voice) so I'm quite sure my Note 2 could do the same with my Nokia 5230. On top of that, I'd really like my Note 2 to get the calls of my Nokia and redirect them to my Sync, this would be heaven!!
If someone has a solution, he/she's my angel!!

i need a replacement for my jaybird x2 but dont want to get the X3 now that bluetooth 5.0 is available. Or does anyone know of a good headset that will be release soon with bluetooth 5.0?
is it because your x2 doesn't work with the S8 ? because it doesn't work with mine either .

it works fine just the battery is getting old. and itll be nice to have more range with 5.0
I am also wondering if there are any Bluetooth 5.0 headphones anywhere yet. I can't find anything.
Also looking for BT 5.0. Still using the original Bluebuds x ! Battery only lasts me about 4 hours.
This is driving me nuts--there are some pretty legit reasons for wanting BT 5.0 headphones, and I don't really want to buy a replacement pair that DOESN'T have BT 5.0 because that'd be silly now that my phone supports it . . . blech. There has to be someone out there making them, right?
I searched pretty hard online this weekend and found NOTHING, not even articles/teasers of soon to be released 5.0 headsets.
I'm turning up similar amounts of nothing at all. One wonders why Samsung wouldn't be more interested in playing this up as a feature and thus driving stories about it. Maybe they're too focused on the AKG earbuds they're bundling with the phone, and the fact that the s8 has a headphone jack and the iPhone doesn't? That's my best guess . . .
BT 5.0 is pretty new. The S8 is pretty much the first phone to have it, and I believe it will take a few months until we see some better quality BT5.0 headphones on the market.
But no one's announced plans at all??? Finding the same nothing others are finding - and the silence is deafening.
FYI, X2 and X3 work just fine with the S8 and S8+.
I guess I will continue to wait. I actually really like my BT headphones, sound/battery wise, but they tend to cut out when my phone is in my pocket and I turn my head, which is just annoying.
The biggest issue with making devices that are BT 5.0 is that there is no backwards compatibility. So a set of headphones with 5.0 would not work on a device(Phone, tablet, computer,etc) that didn't come Bluetooth 5.0 capable. Sure they could add BT 4.2 to it, but that would require an additional bt radio. Increasing price and size
My Plantronics edge batteries are about shot. I'd love to buy another Plantronics edge like headset but I'll try to wait BT 5.0. Even if I weren't waiting for BT 5.0 I wouldn't buy another on the chance I'd buy a new headset that has been sitting around for 3 years.

Do you have source on this? I havent seen any articles that says it's not backward compatible. If this is true then it could be a while until any manufactures will release new headsets with 5.0 if the only device currently that can use it is the S8.
I'm not sure why you'd think they weren't backwards compatible. I've gone through every previous generation of BT and to the best of my recollection if you use a newer gen with older gen the only issue is you don't get all the benefits of the new gen but they certainly communicated with each other.

Look at the Bluetooth website. Or any other website talking about the technical specs. After I did research I tried looking up any devices that are 5.0, besides just headphones and sadly couldn't find any. 5.0 will be phenomenal, just gonna be a bit before it's implemented widespread sadly

I think you're mixing up what I'm saying. The s5 doesn't have bt5. But receiving devices that have bt5 are not backwards compatible with transmitting devices that aren't bt5. Majority of devices that transmit (phones, tablets, etc) will have bt5 and down installed in them, such as the S8, because doing that is simple. As a receiver has to implement all the things that come with higher BT qualifications and standards. Broadcasting BT is much more simple and convenient than having to receive everything connected to that signal.
I'm just relaying information from the bt5 specs though. I have not tested any of this in real world applications
That was a typo, I meant S8. Swype keeps using my old dictionary.
Here is the link I'm referring to as the FAQ:
