(Work in Progress)NFC for all SGS2 - Galaxy S II Q&A, Help & Troubleshooting

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...

What about /dev/pn544?

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.

GPSRecorder settings found in HTC Touch Dual

Guys,
I have found another settings
Go to Program File -> DopodScv, you can find the "GPSRecorder.exe" file
The program runs under Traditional Chinese character, you may try it out
surely this only works if you have a dopod touch dual?
as your going into dopod scv
Yeah, have it but can't use . Is this another sign that HTC dual has GPS?
It seems like HTC has disabled Wifi, GPS & FM Radio on Touch Dual
Anyway, i'm selling my Touch Dual within these few days... Good luck to everyone
I wish that my finding helps you guys in investigating the Touch Dual, especially the Wifi & GPS
GPS: Why do we need it IN the dual - I much prefer the battery life dividends that my Bluenext GPS receiver brings me. 25+ hrs (quoted) continuous... if it was in the Touch surely it'd be a real battery drain?
WiFi is different though. I respect it's also a battery drain, but I wouldn't have minded that for the occasional use. There's no bluetooth wifi adaptors out there?
Just my take

Hi there Guys i know you have all stressed that there is no antenna for the GPS in the touch dual but i would just like to bring to attention one note, in the uk T-mobile happen to offer the touch dual , with a preinstalled navigation software called Copilot live7 which usess the intetrnal GPS, i have also visited the copilot website and they have confirmed compatability with HTC touch dual. so so so anyone got anything to that?
It's true, sort of
Built-in sat nav
With the CoPilot® version of the T-Mobile Touch Plus, you get live satellite navigation with on-screen and audible turn-by-turn directions. CoPilot� is powerful satellite navigation software for your mobile which performs just as well as a dedicated or in-dash navigation system. When your mobile has sat nav you save on two counts - you won't have to pay for a separate device plus you'll save yourself from ever getting lost again.

[Q] FM radio over bluetooth

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.

If I use a special NFC enabled microSD card with my RedNote 4, will it have NFC?

If I use a special NFC enabled microSD card with my RedNote 4, will it have NFC?
Will it help to install Cyanogenmod/Lineage OS?
Has anyone tried this?
Did not realize this phone would lack such a basic feature like NFC. I need NFC to get to work. Would hate to have to use my old Samsung Galaxy S3 for this and carry two phones around, like an idiot.
Regarding the SD card, I'm thinking of somethin like this: Professional-MicroSDHC-Hi-Speed-Lossless-Certified on amazon. (can't post link, as I'm a new user)
As the sd card ist installed in the sim card tray, maybe the NFC would be negatively affected by the aluminium?
I think it's not possible to get NFC on this device. Like you already said the aluminum body would interfere with the signal of NFC. To my knoledge there are no external NFC devices for OTG use. NFC enabled SD-Cards are additionally readable by NFC but dont act as NFC device for Android.
Side note: the Kernel of the Redmi Note 4 would need to support NFC wich it doesn't
Sorry

Yes a custom ROM would supply it's own kernel but the developer of this ROM would probably not include NFC drivers because the device doesn't have NFC. You would need to build your own kernel for your device and aside from that you would still be in the need of an external NFC device.
NFC is kind of a hardware so phone won't be NFC enabled whatsoever.

Silly question :) (NFC)

is there any way to add NFC on the xiaomi redmi 5 plus?
I recently upgraded from Samsung galaxy s6 and I missed the NFC
is there anyway with soldering and mods to do something or not?
NFC is not a software feature that could just be enabled, rather a hardware dependent option that requires a nfc receiver and beamer at the back of device, generally present in the back battery cover
So if your device is nfc enabled i.e has a NFC chip then it can interact with other devices and read/write nfc tags etc , otherwise you're out of luck and there's nothing you can do
Nfc dead trend
Is there anything like NFC dongle or something that can be attached to my mobile that works exactly like nfc in mobile ?
I'm pretty sure this phone doesn't have NFC, since the people in China prefer QR Codes in apps like WeChat over Google Wallet.
Unless you want to do stuff with NFC tags or use it to pay without your credit card, it's not really that much of a loss.

Tab 7+5G and no factory NFC

Hi all, as we know the Tab7+5G has no NFC (Near Field Communication) hardware or software/firmware installed
by Samsung, while I know this is not a mobile phone it has everything else that a mobile phone can do, so
I don't understand why Samsung would leave off such a cheap production add on, maybe something to do
with their flat magnetic Keyboard/Cover installation to the back of S7 Tablet?
Anyway, for the expert members (I have looked around and googled) is there anyway I can
install an aftermarket removable NFC Dongle into USB C port and perhaps run an appropriate
App to activate so I can get working NFC on this S7 Tablet, or is it impossible or non-existent.
Thanks from this old guy, sorry to ask such a question but I cant find clear answers.
Yes, it's true, this tab lacks NFC. When I bought it, I just assumed that it had it, and was surprised that it doesn't.
It also doesn't have a proximity sensor, which is more important to me, but not a deal breaker.
Another thing that really ****ing peeves me is that you can't get the 256/500GB variant's if you also want LTE/5g. For some retarded reason, they restricted the carrier versions to 128gb only. Why can't I have 500GB AND 5g compatibility in the same tab? The WiFi only/carrier version's of the Tab S7+ are exactly the same size, there's no technical reason why the carrier versions can't have the larger sizes too.
Who are we lowly users to question the design decisions of Samsung?
