BT Tag Writer is application that offers you way to add NFC pairing to your old Bluetooth speakers. NFC pairing allows you to pair, connect and disconnect the device just by tapping the NFC tag with your phone. This application is still under development and this thread can be used to request changes and new features for this application.

Hello everybody.
I have been now writing application for Android devices with NFC capabilities. It basically offers wizard interface for writing new NFC connectivity tags for your Bluetooth speaker(s)/headset(s)/etc. And software that will take care of the actual pairing/connecting, when you tap the tag with your phone. NFC pairing is something Nokia does with N9 and it's Bluetooth speakers, but it looks like Android still doesn't handle this well out-of-the-box. Also I still haven't found easy to use connectivity tag writers for any devices.
Sort demo of application in it's current state: Check youtube video kzoG5VM6VcU (can't have this as a proper link, as I only have less than 8 posts to this forum, sorry)
Before I release this software to market, I would like have some people testing it with their speakers and devices. I really hate alpha level software in market. If you have Galaxy Nexus, some sort of Bluetooth speaker(s)/headset(s) and hopefully some writable NFC tags, and you would like to help me to get this software tested: Please tell it here. I still have some small things to resolve before this is ready for closed testing. If you like to help me to get this tested please also tell what sort of Bluetooth device you have and what NFC tags you have available.
I will most likely release this software as free (gratis) and probably in open source (don't know the license yet). So I am not planning stealing your time and then making money out of it. Only thing I can offer to you is to add your name to application's thanks list.
Also if you know software that already does all this, please tell. If my software does not bring anything new, I have to redesign it little bit.
Thanks.
I'd like to test your app.
Got the same NFC-Chip like you (mi(d)fire or something like that I've bought for my old Nexus S) and a Nokia BH-504 Bluetooth Headset and for sure a Galaxy Nexus and a Galaxy S, too
Just tell me how I can help testing...
i would test as well buddy!

For now this is ICS software, do you happen to have some unofficial 4.0 image in those? I kinda would like to make this 4.0 only software, as all NFC devices most likely will get that update.

I'd love to test this. I've been using NFC Task Launcher to do something similar but it doesn't currently support connecting to a specific device. I'm running ICS on a GSM Galaxy Nexus and have several A2DP speakers I could test with.

I will fix few annoying things and then will put link to debug apk-file here (maybe Wednesday). I will try to see if I can make it run in 2.3.5+ too. Anyhow software will be limited to Mifare Ultralight tags (original and C versions). I have to buy other type tags to see what I can do with those, but that's later. Common Ndef writer classes does not work at all with Android or then I'm doing something wrong.
Android also really limits clean ways to do intents for more complex tags. So these tags software now writes are not proper connectivity handover tags. Just the core part of those is used and stored as single NDEF mime item and then this app is marked to handle those NDEF messages/records. Positive side with that is of course that information fits to smaller tags. Also PIN code storing will be probably done little hacky way to the first version.

So many different Mifare tags out there. Mifare Classics will not work (for now).
Anyway, pushed software to market after all. In few hours you should be able to find it from there. Offer still stays, if you can try it out and report issues here it would help. I had to drop headset support for now as it didn't work as well as I hoped.
Great! Will try it out today. Here's the market link https://market.android.com/details?id=fi.siika.bttagwriter

Missed that bit. I really must learn to read All the Mifare tags I have are Classic ones.
A couple of initial thoughts after myfirst use of the app...
1) Back when I was on 2.3.7 there was a Bluetooth A2DP widget I used (can't remember the exact name now) that, when you created the widget, would display a list of already paired devices that supported the A2DP profile. Once you'd picked one the widget would attempt to connect to it automatically.
I'd like to see your app do something similar rather than having to go through a pairing process with a device I've already paired with. It's a small thing to do I know, but I'd imagine most users will have already paired with their speakers before ever finding your app. I don't know if you can enumerate paired devices supporting the A2DP profile in ICS though.
2) When your app was scanning for BT devices it would find my speakers but would only display the BT address. It didn't display the BT device name after waiting for several seconds. This may be a BT stack problem though.
3) It looks very nice!

1. Yes my app does not trust the already known devices list. Have to see if I can get that too. Anyway my application does not pair devices that have been paired already. It simply is stupid to not offer those. I have to check if I can used paired devices list too. I have to add some indicator to list what devices are then old known and what are just found with discovery.
2. I have seen "no name" issue only once. But yes, that's "stack problem"... I hope
Anyway I think I have to try to add Mifare Classic support first.

Sorry for spam, but finally this will be mine 8th post
Request to list already paired devices is now added to Market version (0.3). So no need to turn already paired devices to pairing mode when writing tags.
Support for other than ultralight Mifare tags might take some time. Thanks to keys etc those tags are not ideal for this use. I think I will try to add headset support first.
Just to confirm that 0.3 is listing my paired A2DP devices

My unofficial NFC tag type list (from memory, might have mistakes)
Mifare Ultralight C is my recommendation. If you plan to use this for this, or for example: storing your contact information, storing some url, storing application starter information etc.... Simple, cheap and easy to use alternative.
Mifare Ultralight (non C) is too small for almost anything. You can use it anyhow with my software (limited features) and you can fit sort URL to it.
Mifare 1K, Classic, etc... these are for more secure needs. Or if you really want to store a lot more information to the tag. For non secure usage (e.g. my app) the secure features are just annoying extra that makes things more complex. Key based security so if you mess up with key, then you can't read or replace that data anymore. Also kinda "proprietary alternative".
Felicas are Sony's alternative for all these. Probably not easy to find outside Japan. Topaz is good alternative for Ultralights, but I don't know how well Android supports those currently (haven't tested). And if Broascom/Innovision still makes these? Not too easy to find anyway. And then there are many more... it's a total mess and maybe the main reason why it's so hard for NFC to break big time.
But for the most of use cases: I assume Mifare Ultralight C is the best alternative.
NFC Tag store examples:
TagAge - I'm using this, but mainly because I live in Finland.
NFCDog - is one UK alternative.
And many more, Google search is your friend. And this message has't been paid by either of these stores

I have a Samsung Galaxy SIII and just made my first NFC-steps using some Samsung TecTiles tabs.
After trying a few NFC apps from the Google play, I have a few basic questions.
While basic functions like p.ex. switching Bluetooth are available in all apps, other functions like p.ex. showing a pop-up, text-to-speech or calendar functions are only available in only in one particular app.
Is there a predefined set of nfc-functions for any given android version or the app-author is basically free to program any function he can think of?
I tried to import a tag in one app which i previously have written with another app. This didn't always succeed. I could understand that there is a problem with importing special functions which are unknow to an app, but at least the basic tag and the basic functions should be recognised by all nfc-apps.
As the nfc-apps progress, will we see new functions/possibilities or will it stay about at the present level as the available functions are limited by android?
My device is locked, mainly because it was mandatory by a VPN installation.
Is there a way to unlock it 'automatically' thru NFC? I know this can be a security issue, but it would be so handy just p.ex. to put the phone in the car-holder and it would automatically go to the home screen or the car screen, and also during driving its annoying when the device has a time lock and needs to be unlocked in the middle of an intersection......
What is the power consumption of the nfc-module in the S3?
Thanks for your input.

There is a set of predefined nfc-functions, (like open a webpage, vcard, open an app..) but this set is very very limited and even the mentioned Bluetooth function is not included .... in fact, bluetooth needs a little hacking, because the official api does not support to turn on bluetooth without asking the user .....so basically a developer can (/ has to!) implement every function he wants, but in reality a lot of functions are blocked on non-rooted devices, because android defined them as security related....
I tried to import a tag in one app which i previously have written with another app. This didn't always succeed.

As mentioned the basic set is very limited.... it´s based on the nfc forum specifications and using nfc to control your device, is something these guys never had in mind ....so, sure you could use some standard nfc writer and write a webpage on a tag..... and this should be something every nfc device (not only android, but also blackberry, windows phone etc...) could handle .... but if you want to control your device, you need a more sophisticated app .... and there is no way to import a tag from one app to another ...
As the nfc-apps progress, will we see new functions/possibilities or will it stay about at the present level as the available functions are limited by android?

The functions are limited by android .... and my feeling is, that with every android update it get´s more limited! --> on Gingerbread, nfc was enabled while screen was off --> a function they skipped with ICS (ok, again, on a rooted device you could change the NFC.apk, to re-enable it) ... the last JB update declared the airplane modes as a security feature ... so no luck with airplane mode since 4.2 ...only to mention 2 examples ...don´t get me wrong, I don´t think it will stay at the present level, but it´s definitiv not in googles focus yet .... personally, I have a lot of new functions and use cases on my ToDo list, so I would say it´s just the beginning

yep, but again some hacking is envolved ... root your phone, change the nfc.apk, etc. ...I think there are several threads regarding this topic available ....

Since I haven't found a thread concerning this and just discovered this myself yesterday, I thought I'd share:
The rSAP for Android app has been compatible with the Nexus 4 for quite some time now. The dev found out that all phones using a certain broadcom stack can be made compatible.
You can find more information on his website
http://www.android-rsap.com/
and grab the Installer (ROOT Required), Trial app and Full app at the respective links.
9€ may not be cheap but for me being able to use my Nexus 4 with my VW Infotainment system again is huge especially since there are only a
few android phones (namely Samsung and some older HTC ones) that support the rSAP profile. The dev also takes this seriously and maintains
communication via the forum on his website, accepting logs and trying to fix stuff that doesn't work.
Cheers
Hi,
Sorry, I had already posted this on another section but I think this one is more appropriate and can't delete other post.
I have a Joying JY-NL124 android car radio, which does not have an accelerometer. I bought the Yocto 3d V2 http://www.yoctopuce.com/EN/products/usb-position-sensors/yocto-3d-v2 to see if I could get it to work with torque and other android apps for the track but although android sees the device the apps do not. I am not a programmer, but is there a way to get the apps to recognize an external accelerometer like some do for an external GPS?
Very interesting. I would like to know as well. It might also be usefull in navigation to get a faster direction orientation.
I was reading up on this again and this bit means someone with the know how would probably need to code something
The main advantage of this solution is that you don't need to install a driver to communicate with a Yoctopuce module, as the HID layer is always present. You only need to add our library, that we provide in source form, to your driving software for it to be able to directly talk to Yoctopuce modules.

Uff, sorry for the late reply. Life has a way of getting in the way of interesting projects. I'm about to restart this project since I'm using the car a lot on the track. It's weird that the units don't come witha compass, gyroscope, accelerometer, etc, considering they are meant to be used in moving vehicles.
Definitely post up if you figure it out.
It would be nice to get it to work with Android as a whole. If that's the case you might need to talk to one of the ROM developers to see if it's something they can do ROM wise or even a custom kernel.(the kernel bit might be a little harder)
Did anybody get this right. It would be cool if these usb accelerometer could work in the apps

I'm very interested to understand whether this is possible as I am thinking about a similar setup. You tried the three Bluetooth tips in the roll up thread?
https://forum.xda-developers.com/an...roll-joying-2gb-sofia-mtcb-mtcd-tips-t3555249
"Bluetooth Tethering & BT Settings", "Difficult to pair BT devices" and "Modified stock bluetooth app to allow connection to all devices"
Have you tried external GPS for higher refresh rates or is the Head Unit gps refresh good enough for the track?

Sorry....USB not Bluetooth... Also discouraging. I was hoping USB would be an alternative to BT for track add-ons...
I too have an Android head unit and do track days, and have the exact same interest as you. I use Harry's Lap Timer. I have the Pumpkin AE0273B head unit. It too lacks the compass and accelerometer. I too found this to be a very unfortunate omission.
I have developed apps actually so I do know Android program to some degree (although I am sortof a hack, not a pro). I have apps on the Play Store (since I can't post links just search Play Store for developer JimRoal). I saw the Yocto stuff. When I get some time I will look into this some more.
Any update on this? Would also like to add a compass / accelerometer to my joying.
Also interested. But on a newer 10.0 unit. Something I am going to look into.

Sad that over 4 years after I first posted this we still don't have a unit with these features. I finally gave up and bought an AIM Solo 2 DL.
I'm looking for a newer radio though, since mine is older than this thread
Still waiting as well.
Looking forward for solution, we have also WIMOTION sensors in the market with sample android apk but I'm not a developser so, put things together is hard for me !
I think the hard job is try to mock the sensors in Android AS IF external accelerometer was factory embeeded (allowing apps to recognize it)
Nothing new about this project / idea ???

Once you've figured out how to modify the kernel, you should be good to go!
Another option could be sensor to serial over USB, via a compatible adapter, write an app and there you go. Of course it won't be standard Android though.
Drivers are here
https://elixir.bootlin.com/linux/v4.14.133/source/drivers/iio/imu/st_lsm6dsx
The problem is adding them to kernel !
You dont need to add them to the kernel. You will need to implement an Android HAL that can read the values of these sensors. Its not a trivial task but also not very hard if you have access to the source code
Can anybody point to a bracelet with documented set of bluetooth commands? I want to use it's sensors and power saving features, but all required logic is expected to live on my android device (actually smart watches). If there's already is a similar thread it would be nice to have a link to it. If there's no such thread then may be here we can discuss issues with the bracelet based sensors and smart device based logic system.
Out of luck

Hello
I've just asked the very same question. It is a huge market outside for that kind of devices, but it seems that nobody cares. I'm really curious what is the REAL reason...
