Nexus 7 as hands free bluetooth device?

I know that at the moment this isn't possible, but does anyone know if there is work being done on the Android bluetooth stack to enable a tablet to be used as a bluetooth hands-free device? A bit of searching shows that it is a regularly requested feature but I can't seem to find any info on any developers who are definitively working on this (except for one little questionable nugget that stated that the CM developers were playing with Bluetooth. Hardly enough to go on.).
I want to incorporate a Nexus 7 into my 370Z as a carpc but the lack of being able to integrate phone features is holding me back. Using data apps like grooveip are a no go for me as data connections around here aren't reliable enough for consistent daily use. Thanks in advance for any info.

I'm not to sure of what your asking, but if you wanna make calls from your tablet using BT this app allows you to do that as well as send SMS and MMS from it https://play.google.com/store/apps/details?id=com.apdroid.tabtalk hope that helps and is what you mean

I appreciate the suggestion but I don't think this will work. What I would like to do is mount my tablet in my car and use it as a front end for my phone to make/take calls the way an OEM bluetooth car system would normally work. My understanding is that your tablet must be paired as a hands free device, which android tablets currently don't do. I looked at Tablet Talk but when using that app from what I can gather when you accept a call on the tablet it actually activates the call on your handset. Ultimately I want to use the tablet as a hands free solution as I drive stick and holding my phone to my ear while driving is a no-no.
In the past I've used bt headsets but I lose them constantly and frankly I'm tired of replacing them. Oh well.

Well, good luck in your search! And you hit tablet talk spot on BTW lol. Oh and if you do find a solution, plz post it! This sounds like something I would love to use.

Thanks. I'll thinking I'll probably go the route of a more traditional carpc for now, but if and when this becomes a feature you can take advantage of with android tablets I'll have to reevaluate the situation.

This would be a great extension or compliment to the various apps that let you send/receive SMSs from your tablet via your phone. If I could at least receive/answer calls too, I could leave the phone elsewhere at home.

Just to let you know I've contacted parrot and garmin with regards to something like this.
I want a solution where I can make my nexus 7 a full media center with DAB radio and a good sat nav without needing a cellular link and hands free for my phone which includes the voice commands available through the tablet.
So hopefully they will get back to me and I'll post up here what they say.
Something I haven't solved yet either is getting all the antennae feeds into the nexus, I was thinking of getting a sharks fin antennae and wiring them into a raspberry pi to then blue toothing them into the nexus, I could also then attach a HDD to the pi to use it as a server to.
I want to do it this way so I can take the 7 otu and with me if I wish, rather than having it hard wired in. also if would allow for device upgrade.
Theres a nice thread on install and with references to the tasker app to get the tablet to work with the ignition and other functionality like that;

BT app
There is an app under development for this I think. play.google.com/store/apps/details?id=com.funkyandroid.phonelink
I'm thinking of dropping a Nexus 7 in my car but the lack of hands free bluetooth is kind of a deal breaker.

Did anybody ever get this working? I have my Nexus installed in the car, and would love to be able to use it as a speakerphone. I don't need to actually be able to make the calls via the tablet, just need to be able to use it as a basic bluetooth speakerphone / headset type of thing.
It sounds like it should be something fairly simple, but I cannot seem to find much.

I have been wanting this for a long time, I'd love to be able to take my older Android phone and re-purpose it as a car GPS/Internet Radio/Handfree, etc.
I know the Samsung Galaxy player has this functionality, I wonder if any of their devs could help out.

if this work in linux so i think can work on android
Hi to all,
i been looking for this "bluetooth role" for long time. I have read a lot of forum and the entire XDA posts about this..
it seems that this is the definitive question like "what is the answer to life the universe and everything" simple 42
and it seems that is the paradise for all want to make a carputer/droid/tablet/**** car radio replacement... so... i'm one of you
this post is for some devs (i'm a dev too) i'm asking for help ....
the problem is: which android version do you want to use?
why this question? simple: from the android 4.2 google has decided to trash the bluetooth bluez stack and reimplement the wheel with bluedroid...
i read the documentation about bluedroid at this site:
https://source.android.com/devices/bluetooth.html
and there was written that there are some profiles actualy implemented but not the Bluetooth Hands-Free Profile server.
Ok it's not a problem, taking a look to the template of other profile i can implement it.
now the question is HOW DOES IT WORKS?
so i searched and bum this is how:
version 1.5
version 1.6
ok and now? and now i tried to find some similar implementations and...
after another night of search i found this....
HFP For Linux
where there is the downloadable source code.
now I think we have all the necessary to make this possible...
BUT there are some problem that i haven't resolved yet for a lack of knowledge of course.
it seems that the hfp override any other profiles on that example, it's not bad, in a system that i want to use i need only a HFP profile and AD2P togheter all the rest is useless
i think that this at the end is a fork of the standard android project and how I/we can put it into a rom or a patch and who want to add to a rom/kernel? how it can be done? is a patch better ? a new kernel like franco's or better to submit to google?
I hope to have intrigued someone with this post and I hope that somebody can link me to some documentation to understand how to put all the information I have together.
ps. i have tried to reply into this thread:
[Q] Android phone as bluetooth headset?
but of course i have to few posts to make my suggestion there

I may be out of line here but try reading about the gmate+ device.
I got one paired with my Nexus 7 32gb right now and currently using it as a phone. I believe there are other similar gadgets out there, as I've done some researches before I actually got mine to work. I have yet to try it with a bluetooth headset paired because I lost mine just on the day when I was about to try it out.
Anyway, one problem here is, the app for the device is currently not updated so there are a lot of things that need tweaking and one major issue for me is the ringtone. As I have posted here before, sine N7 does not have native ringtone, there's no alert tone for incoming calls. As for text messages, the notification alert tone works. I know there's also GPRS for it but haven't tried it out yet.

Try these options...
As far as an option for a Nexus 7 you may want to try a sip dialer like 3cx or linphone or zoiper and establish a free sip account at iptel.org or something. As long as you have wifi or a 3g connection which some tablet have you should be able to make and receive calls, or try ""Blue Fi" from the play store. it may work.

I just got a new Nexus 7 for the same purpose of replacing my vehicles head unit with a tablet.
I am digging into the BT stack since I believe that I should be able to implement (or port) the profile on top of Android 4.3 assuming that the SCO data is available through the raw BT connection. There is an open source HFP implementation on sourceforge for Linux that migh be close enough to do the trick and save a bunch of coding time. It's going to take a while for me to get the time to dive too deeply into this one, but if I succeed or come to the conclusion it can't be done, I will let folks know.

Hello guys.
I am going to buy Nexus 7 for my car for the same purposes, - navigating, internet.
But mainly is for the Hands Free function.
Unfortunately, people saying nexus can't use it. But it's lol...I don't believe nexus7 doesn't support hands free.
Gentelman, tell me any way to make nexus 7 works hands free.
Thank you in advance.
P.S. if you ask wham am I mean when saying "hands free", so there is an example http://www.youtube.com/watch?v=ZEFjDKtlao8

Use some Motorola MotoActiv Bt code?
I have a Motorola MotoActiv running watch... Features gps tracking for running and biking, MP3 player and Bluetooth... The Bluetooth is mainly used for wireless headphones, but if you have a Motorola Phone, the watch can display text msgs from the phone and you can use the headphones/mic through the watch to take calls. (the idea being that you can leave the phone in a pocket or backpack while you're bike riding, I guess, and still take calls.)
The device runs Android (I'm sure someone's rooted it on here). Maybe that code can be dissected and repurposed for what were all looking for??

Just an update on something I said in my previous post... I was looking at my MotoActiv watch today and it says you have to have an "Android phone" not a Motorola phone as I said in my previous post. So I'm wondering if the phone audio over Bt can be reverse engineered from the Motoactive watch for other android devices.
I actually decided to root my watch today just for the fun of it... it would really make the perfect "Car Head Unit" as it has Android OS, MP3 capabilities, FM Tuner, Bluetooth and Phone audio over Bluetooth built in... if only the screen was larger than 1.5".

Looks like the Nexus 4 and Nexus 7 2013 are getting some love in this area with a new custom stack:
http://www.bluez.org/bluez-for-android-status-update/
Looks like you need some compiling skills, but I think this is what you are looking for.

It must be work... Or not?
Hello guys!
I'm thinking on a same project for a while. It doesn't matter if not work for me, but would be great if yes.
I found something 2 days ago:
Parrot Asteroid Smart
This is an android base head unit/navigation, and the bluetooth handsfree is working on it. How it's possible? Any chance to port it into the Nexus 7?

solution
So i had an idea today and decided to call my carrier (Cricket). They told me it is possible to purchase an extra sim card and they will program the imei# to match my phone. This will enable me to make and receive calls on my tablet as well as my phone using the same number. Also i will have full access to my data.....problem solved with only 15 dollars. I hope this helps somebody.

Mota smartwatch on groupon 2/3 $50

Anyone know how this handles incoming text messages. Does the watch vibrate and are texts easy to read in day light or nightime? They seem to get, unlike many reviewers, that one killer app is not having to take your phone out of your pocket to answer calls. That function is also important to anyone bombarded with incoming texts. It is odd that Mota's description makes no mention of text messanging. This is the main way I use my current device, an ancient sony liveview (given new life for reading incoming texts by excellent openliveview software).
Given pricepoint, novel functionality and stylishness clearly deserves its own thread.

I would steer clear of this device. Very, Very limited functionality, poor build quality- my battery was DOA, When I finally reconditioned the battery, it had constant connection issues. Got rid of it quickly.

Guys, this look any other cheap $40-$50 bluetooth bracelet I have seen being sold on ebay, amazon, or chinese retailers (like dx.com) for the last 2-3 years. Its just a bluetooth caller id notifier that vibrates on calls, shows who is calling, and plays music from your phone like a remote bt speaker. It's no different than this $40 feature watch I reviewed here (http://forum.xda-developers.com/showthread.php?t=2435751) but in a bracelet format.
If you ask me, this is no different than all those scams trying to sell already existing products on KS or IGG lol!!! They just got clever and doing it through Groupon to attract more suckers, I mean buyers
This is not a smartwatch, it doesn't show emails or txt msg or anything else, and it only supports BT 2.0.

Thanks for info
Thank-you to the previous posters for saving me some money.

[Q] Help! Flylink s18 Smartwatch

Hey, I just bought a nice S18 smartwatch. The guts are the same as the LEMFO and ZGPAX models so I guess at least someone has tried this device. I quite like it - The display is nice and sharp and it's comfy to wear. However, I just CANNOT get this thing to connect to my LG G3. It pairs straight away but that's as far as I get. The box gives a username and password to a website that does supply apk downloads for all their products - except the s18. There is a download for a U8 device, which I gave a go but to no success.
Can anyone help? This fairly decent smartwatch is looking very likely to end up in a drawer next to my old nokias, digi cameras and earphone nests.

Just ordered this watch. I have an LG og pro. 7-10 days and I'll post how I make out.

I believe the Flylink S18 (ZGPAX S18) is a standalone phone. I don't believe it supports smartwatch (called Smart Bluetooth Sync by ZGPAX) functionality in terms of pairing with a phone to get notifications. The ZGPAX S12, S15, S28, MQ588, and S19 support Smart Bluetooth Sync.

That's the case. No sync. But calls are clear. Text are a pain but work. Guess next ill put some music on it.

Smartwatch for cycling.

I have a question. If I would like to use the SmartWatch following situation: I'm going on a bike, on hand SmartWatch (without SIM in slot), in a backpack or pocket smartphone HH6 (with SIM) paired with a watch by BT. Someone calls me, I answer a call on the watch and lead the conversation by saying to the hand on the steering wheel. At this time, simultaneously goes GPS and Endomondo. It is feasible that equipment? Such a test network I have not seen, and the only excitement is that you can let go of a game or film. Which to me is a complete misunderstanding, taking into account the size of the display and battery.
I thought about d5 but there probably is not possible to carry on a conversation by saying to watch when the SIM card is in your phone.
Can the new K18 (2016) would give this advice? Is K18 and K10 the same thing?
Wysłane z mojego H60-L04 przy użyciu Tapatalka

I would say a yes - sort of... There are considerations which would affect your scenario that would impact *any* device regardless of who manufactures it. If the phone is in a backpack and the watch on your wrist, there there will probably be issues with BLE signal quality between the devices. However, if the phone is on the side where you're wearing the watch, then there will less drops/glitches. This of course is *before* we talk about the quality of the wrist device itself - in how well its microphone/speaker might work, etc.
With all of that said, I have a similar setup with several devices. I just received the No.1 A10 (mainly for swimming but also for general use when out-and-about) and the K9 3G (more for 'civilized' situations) each of which I pair with my HTC one M8 when in-use. I also have a SIM in my K9 3G, both as a backup for my phone and for SMS (I've been involved with the SWApps Link app roadmap since early stages - so I test its failover from BLE to Push and SMS) and for tethered use/notifications from the phone. I'm not sure if that helps you, but it should give you some 'color' on the options that are available.
I think just about *any* device will promise to do what you suggest. But there's bad news: the real world. The little bit of time I've spend with the A10 as a transponder (phone calling **** Tracy style, but the call is to/from the mobile phone in my pocket with the A10 as mic/speaker) has been bad enough that I pulled the phone from my pocket and took over the call. I'll spend more time experimenting with it and the K9, but I'm not sure if the technology is really ready for the real world, if the hardware I've selected is actually up to the task - or - if my standards are simply too high.

I thinks all you need it an Android wear/ or Original Android to connect with your phone and also can run Endomondo. To answer the call, I think it will be better if you use a bluetooth headset, It will better for music, voice training and call.
Now I'm using a D5 with backup sim with a mi bluetooth headset to track my running. I let my phone home and set an automatic app to send a sms for someone who call my phone to call to my backup number in necessary case. And it just works fine with me (I try and D5 can run almost all running apps quite good. But for see the map when you run, looklike Runkeeper and Endomondo is the best)

So at the moment is not fully good watch, which can be used for making calls, if your SIM card is near the inside of the phone?
I care not to insert every time the SIM card from my phone to watch and vice versa. I also do not want to run another SIM number.
Are D5 offers such a possibility at all? In the movies on YT people call from the watch, in which is placed SIM card. I have not seen anyone talking on his watch and the SIM card in the phone.
Are currently in the Chinese market is something better than D5 in price to approx 150$. I mean similar or better functionality. I mainly depends essentially on the good battery life, protection against light rain, GPS and the communication with the phone, about which we speak. Maybe M8? There is battery 600mAh.
Are K18 for example, would not be better? There is probably the SD card slot.

You confusion is well founded. My two examples, the No1 A10 and the K9 3G are to show examples of *completely* different device setups.
A10 - Bluetooth connection to phone only - no SIM. It has a microphone and speaker for using like a bluetooth headset for answering calls, except it's on your wrist. The No1 A10 can be found online for $50-60US.
K9 - It can *both* function as a bluetooth extension to the phone like the A10- - AND - also operate on its own with a SIM chip inside the watch itself. Depending on how your carrier operates, you *may* be able to set up the SIM on your wrist to look/act/feel like the SIM on your phone (presenting the same number, receiving calls, etc) so that the experience is relatively seamless. But aside from the technical hurdles as to whether the telecom/mobile carrier actually allows this function - there's the cost. I paid $124 for the K9 3G and you can find it for prices in that range at various outlets online. The cost of running a second SIM and related hassles vary widely.
The D5 is more similar to (and perhaps even exactly the same as) the K9 3G though I don't know the D5. I chose the K9 because of the 1900 support that allows me to use it on T-Mobile in the US.
These two different device profiles give different positives and negatives. One the one hand, the K9 is a much "smarter" watch, with more capaiblities - being that it runs full Android 4.4.2. On the down side, it burns through battery very quickly when in heavy use (such as running Google Fit to track steps/location via GPS during workouts) - and it isn't fully waterproof. The A10 is water "resistent" and presumably more able to handle the rough-and-tumble world, and the battery last several days without a charge - but - it has no SIM, no memory to speak of, and relatively limited functionality.
That is a very, very long way of saying YMMV (your mileage may vary).

Best cheap smarwatch? (20 USD)

I would like watch with decent autonomy and notifications, not really interested in being standalone.. A site says the best is gv18 but i would like to hear your experience

Mine?Mine is a standalone watch D6. full functioning.
I know very little about other watches.If you like this watch,you can search it on this forums.
