Anyone else running this and having issues with BT?
Blue tooth enables fine, but will not detect any of my BT devices.
i know its just a beta, but it says BT is working.
i would post this in the CM7 forum, but not enough posts in general to be able too.
I had an issue with it accepting the pin codes. You have to type it fast!!! took me at least 10 attempts to get it to pair but it works just fine once the codes in.

Hi I dont you use bluetooth but you can forward this in the development section on this forum there is a cm7 beta 3 thread
http://forum.xda-developers.com/showthread.php?t=929666
or better still try Elelinux's rom base on cm 7 which I am currently using ... Just love it
http://forum.xda-developers.com/showthread.php?t=932377
its working fine now, for some reason the phone wouldnt detect any BT device (want trying to detect the phone with other devices) , but i thought what the hell, i enabled the discoverable option, and it started picking up other devices, even now that discoverable is turned off its working fine.
dont know if it was that, but thats the only thing different i did, and now it works.

I don't know which one is better, any suggestions between 2 ROM there?
Hey guys,
I was just thinking about that nasty little problem with cyanogenmod and our legends and since there was no meaningfull advencment, we could put some money on it. I think from 5 to 10€ for each doner would be enough or what do you think? Of course the developer has to give us an account to send the money to.
I would just like to use the FM radio and since it is working on desire for some time now, why not on legend.
So who is ready to do it?
would support that idea.
It is already stated waaaaaaaaaaayyyy before. The FM radio WILL NOT WORK on the Legend because of it's alien architecture. Don't ask me, I don't know ****. But if you're do want to make a donation then you can donate to Ali Ba which has been the sole reason CM is running on the Legend.
This is a good idea.

here on this link http://forum.cyanogenmod.com/topic/8260-fm-radio-support-for-legend/ ale baba himself says it is possible but that he hasn't got the time for it. So it is possible we just need someone who will do it. But first of all we need more people.
I'd consider doing development on this. I was wondering why there was no FM Radio app on CM7, LOL.
At the very least I can commit to finding all the info I can gather on this issue. I have no (satisfactory) employment at present and want to break into the Android specific field.
I have 14 years experience in embedded Linux development, including lots of low level kernel stuff. In a previous life (more decades ago than I dare admit) I did electronics engineering stuff, and I still love the low level nuts and bolts.
I'm pretty new to Android however, got my first cellphone (ever!) 17 days ago, first Android phone 15 days ago, and my Legend yesterday.
I think I can learn quick, I'm CM7 nightly, S-Off, new radio one day after getting it, LOL.
So my point is I, and this project, could use help in areas of Android specific knowledge.
Does anyone know if the normal FM radio app I've used before is proprietary Google code ?
Are there any generic FM radio apps that would work if standard drivers existed ?
My quick research on this is that only a driver might be needed. A V4L (video 4 linux) driver, which I have already had some experience with.
But there DOES seem to be a V4L driver already for Linux for the TI WL1273 chip apparently used in the Legend, and apparently a number of other phones. So in theory, this job might be as easy as integrating an already written driver in to the CM kernel, as a kernel module or 2. There MIGHT be some copyright issues with any chip firmware though.
Alas, some comments indicate using such a driver might interfere with Bluetooth functionality.
Interesting stuff about the 1273 chip is that it may support an FM transmitter, and it supposedly supports WiFi N. But who knows if needed hardware support might not be on the PCBs.
^ wow! where have you been all our android lives, bro? link on the post above yours answers some, if not of all, of your questions & covers a lot, i guess. cheers!

I've been reading that there IS an FM Radio app integrated into CM now. It comes from MIUI, a chinese group of some sort that also makes an Android ROM.
The app apparently uses /dev/radio* which is the standard V4L radio interface. I have these also on my Hauuppage PVR boards I used for HTPC before I went completely digital for movies, tv, etc.
So yes, what we need is integration of a driver into CM kernel, but coding may be needed to fix bluetooth driver interference etc. And of course who knows what else might be needed.
I'm reading that FM is much more important to those without data to stream. Not all of us live in wireless data dense cities and countries.
Would be interesting to see what frequency range can be received and maybe transmitted.
Would be MOST cool to stream from video camera to transmitter for local "pirate TV" type functionality, LOL. Actually can't imagine ATSC or even NTSC (or PAL etc.) encoding possible, but wireless streaming will do the job...

Thanks for joining in, great highly appreciated. If there is any time left it would be nice if you could look into the GPS problem with CM 7 it is currently not addressed.
Anyhow thanks for your participation and contribution.

@mikereidis
So are you going to try and port it?? If you will and you'll succeded then you will be the legend in Legend community!

I can keep my eyes and ears open to GPS, but best to concentrate on one issue at a time.
What is the GPS issue ? I thought it didn't work on my phone after new ROM but within a few hours it was working OK for whatever reason. And now I see 2 metre accuracy compared to the minimum of 5 on my Optimus Chic.

I'll do whatever it takes.
The userspace FM Radio app shouldn't need any porting work AFAIK. It seems to already be in CM 6.1 ROMs for the Nexus One (any others?). So I'd guess installation would just need to be enabled for other phones.
The tricky part is getting a device driver working that creates a /dev/radio interface for the MUIU FM radio app to use. There IS already a Linux driver for the WL 1273 the Legend uses, but it might need some modifications to run on the Legend.
But there is some complicating factor regarding bluetooth drivers, so it may not be too straight forward. For initial testing at least the bluetooth drivers could be disabled.
What about HTC's kernel source. As I told in cyanogenmod forum the drivers should already be in HTC's kernel source. If the code is there it should be easy to put it into CM7 kernel and use HTC's FM Radio app. Or what do you think?

Yeh, thats the problem. GPS is working on some devices and on others not and nobody knows why. As a matter of fact when I'm running CM 6.1 its working great. Flashing CM 7 no change to get it working. As mentioned others are reporting the same issue with CM 7 on some its working on others not.

When I get tired of Google maps seeming to take forever to figure out my GPS location, I've downloaded and run the "GPS Test" and "GPS Status" apps. I did so and for some time the status color on one of those showed yellow, meaning no GPS fix, but power on.
Anyway sometime later it was working. One of those apps downloaded data to make cold starts work faster and that may have helped. A few things to try for anyone interested anyway.

The problem with running the HTC FM radio app on CM is that it, like many other HTC apps, uses the HTC framework with Sense UI. So CM can't run it, although stock or modded Sense ROMs should be able to.
IMO right now the MIUI app is the way to go, and it's open source so anyone can modify/fork it.
Yeah I think a /dev/radio is likely in HTC source, but it's possible it's something different and/or kind of proprietary.
The Chip manufacturer, TI, and their partners who make RF modules based on the chips, DO have android /dev/radio drivers. So they are definitely out there somewhere.
I think, as usual that "In Theory" this should be a simple matter, in reality there is usually some problems to solve. Otherwise we'd have FM already in CM.
A few pointers:
TI 1273 has a few interfaces for communication. One of them being a (standard) serial via bluetooth, the other one I2C.
HTC did not use I2C because they already had to use the serial interface for bluetooth and it's a lot cheaper that way (that's what all manufacturers do, by the way). The wl1273 driver in the Linux kernel does have support for the FM capabilities, but unfortunately via I2C only.
So basically we already have all the drivers we need in place (tiwlan_drv, sdio), no kernel stuff needed. What's missing is valid documentation about how to enable radio, route it to the headphones, seek/tune, etc.
You could reverse engineer /system/bin/btipsd, which does bluetooth and FM communication in original HTC releases.
Once you are able to control FM stuff (with bluetooth turned on) write a nice summary and I'll ask cyanogen how to implement it. Won't be that hard, given the fact that currently all supported devices use the serial interface via bluetooth.

Thanks ali ba ! Yes I know about cheap manus, I've worked for a few, LOL. Linux VOIP and security appliances mostly though.
By "The wl1273 driver in the Linux kernel" do you mean the TI provided W1273 driver in the CM7 ROM ? I had thought that driver was for WiFi only, or perhaps WiFi + Bluethooth. Or does my seeing an rfkill device mean FM radio is in there too ? Would it create a /dev/radio device ? There are some FM init BTS files that may enable FM.
My understanding is that the WL1273 WiFi driver in the mainline Linux kernel (not the Android kernel) is WiFi only. There's a guy from Nokia trying to get WL1273 FM radio only driver into main Linux kernel but not there yet. That driver will be separate from WiFi driver even though they may both have WL1273 in the name.
I've been finding some HCI commands usable with hcitool to do audio routing stuff at least. RevEng has been a specialty of mine, so I think if it can be done, I have a good chance.
Quickest route to a working FM radio on Legend is to find an existing app for another phone that works.
Phones with the WL1271/1273/1281/1283 chips include original Moto Droid, Droid 2, Droid X, Motorai, Nokia N800 (or N900?), N8 (?), B&N Nook Color.
There's a thread here on XDA about Droid 2 phones using the Droid X FM radio app with success. I tried that app but there seems to be some problem launching the fmradioserver.
I saw a logcat message that may indicate I need to "adb install" the APKs instead of just copying them to /system/app. I tried but got the error that indicates the UID does not match the signature. I guess that's not an issue on Droid 2 (or motorola phones in general?)
Does anyone know if/how to mod/repack an APK to avoid the UID signature issue ?
A few more of my findings for anyone interested. BTW should I or someone create a thread in the dev section at this point ?
As mentioned above a guy from Nokia is trying to get a V4L2/dev/radio driver for WL1273 into mainline Linux kernel. That driver could be integrated into our kernel, but it might take a bit of work. And as mentioned that driver is not in kernel yet and may have lots of changes still coming in the next several months at least.
But TI also has a driver, and it's meant for Android. I haven't been able to grab source code for that driver yet. I think TI driver references WL1283, the biggest baddest version with GPS too. But driver is supposed to work on all 4 variants, down to WL1271.
TI has a command line app for testing fm radio, I think called fmapp if memory serves. It's possible this test app could at least help with exploration.
Unlike the poor original Droid owners, we are lucky that we know our FM receive antenna is connected, since stock Legend has FM radio. But there seems to be a different pin for FM transmit so it's possible we will never be able to transmit FM more than a few inches. But Tx would just be a bonus, but a potentially wonderful bonus.
And, ya know, I'm not even sure if MIUI FM app works with /dev/radio. I was looking at some source and it seems to be hardcoded with Broadcom chip specific stuff.
Oh, and my understanding is that even if we ever managed to get Wireless N working (with a new or improved stack perhaps?), that it will likely kill batteries quickly enough to be effectively unusable. Would be interesting though.
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.
Trying to connect the N4 to a car Bluetooth audio (2012 model car, relatively new, only 9 months old).
(1) I had a very hard time getting the two paired: lots of "connection failed" attempts until they finally connected.
(2) The phone does not send artist/track info which is surprising as I have an older LG phone running Android 2.3.4 and that sends all the info.
(3) Without any music being streamed to the car audio, if I make a phone call via the car bluetooth, when the call ends the music player on the N4 starts automatically. This is very annoying, not sure if it's a problem with the car implementation sending a "play" command at the end of the call or the N4 doing something weird. I tend to blame the N4 as two other phones, an iPhone and the older LG mentioned above do not do this.
(4) The car has a play/pause toggle that it can send to the bluetooth player. Pause works, the player on the N4 pauses, but then play doesn't work, I have to hit play on the device.
(5) After I use bluetooth on the N4, I find that sometimes the widget toggle can no longer turn bluetooth on/off until I reboot the phone.
(6) After I use bluetooth on the N4, the phone sometimes randomly reboots. Not sure if it's really related or just a coincidence. Given (5) above I suspect something is going on.
Anyone else having such a hard time with the bluetooth part? Potential hardware issue or simply buggy software that we can hope to get addressed at some point?
I have experienced the issue with track information not being sent. Also random changes in volume during playback. Seems there's still some work that needs to be done in 4.2 regarding blue tooth.

Is this an issue that can be addressed by flashing a custom ROM or perhaps using a different music player than stock or is there more to it, deep down in the bluetooth drivers and it would need a fix from Google in the form of new drivers?
Yeah I have had a few issues too. My track/artist/album names do not send where my S2 sends them. Also the headunit I have has buttons for shuffle and repeat and these do not show up at all (I assume because it detects they aren't supported). I haven't taken a call yet or tried turning BT off after streaming but I'll give it a shot and see.. My nexus 4 also randomly shuts down for no apparent reason sometimes (rarely atm). I think it's just 4.2.1 problems - I doubt a different music app will fix it (I tried one), custom ROM may work though..
My N4 is paired with an Alpine 135BT and it's worked very well so far. I initially had some trouble connecting but once they were paired I didn't have any additional connection issues. The N4 does automatically play as soon as it connects to the unit. I've got BeyondPod and Spotify installed and for whatever reason it always defaults to BeyondPod instead of Spotify even if I had BeyondPod closed and Spotify open. Not a big deal to me though.
Are you running the stock rom or a custom rom? I had my EVO LTE hooked up to the same head unit. It worked perfectly on the stock software but gave me all kinds of trouble when I started using custom roms. Otherwise, it could just be that the N4 and your particular head unit just don't play nicely together.

Trying to connect the N4 to a car Bluetooth audio (2012 model car, relatively new, only 9 months old).
(1) I had a very hard time getting the two paired: lots of "connection failed" attempts until they finally connected.
(2) The phone does not send artist/track info which is surprising as I have an older LG phone running Android 2.3.4 and that sends all the info.
(3) Without any music being streamed to the car audio, if I make a phone call via the car bluetooth, when the call ends the music player on the N4 starts automatically. This is very annoying, not sure if it's a problem with the car implementation sending a "play" command at the end of the call or the N4 doing something weird. I tend to blame the N4 as two other phones, an iPhone and the older LG mentioned above do not do this.
(4) The car has a play/pause toggle that it can send to the bluetooth player. Pause works, the player on the N4 pauses, but then play doesn't work, I have to hit play on the device.
(5) After I use bluetooth on the N4, I find that sometimes the widget toggle can no longer turn bluetooth on/off until I reboot the phone.
(6) After I use bluetooth on the N4, the phone sometimes randomly reboots. Not sure if it's really related or just a coincidence. Given (5) above I suspect something is going on.
Anyone else having such a hard time with the bluetooth part? Potential hardware issue or simply buggy software that we can hope to get addressed at some point?

(1) Haven't had any connection issues so far on my vehicle or my wife's.
(2) Currently stock Android uses AVCR v1.0 which only only allows you to control via Bluetooth (play, pause, etc) but not send track info. Other manufactures that customize Android (LG, Samsung, etc) will sometimes use v1.3 that supports track info. That's why your old phone did it.
You could install a custom Rom that has v1.3. I think cm10 does.
(3) Again, not happening on my two cars. The only time the music starts after a call is if it was playing before the call. I'm wondering if you have another music/podcast player that is taking over Bluetooth controls and causing problems. I use the stock player and Player Pro. If I don't disable the headset/BT controls in Player Pro I have control issues.
(4) I have the same issue. To get around this I cheat and push the track advance button on the radio to play the next track.
(5) This is an issue I've had on all of my previous android phones. I haven't noticed I my N4 because I never toggle off Bluetooth anymore.
(6) Not having this problem but maybe try solution in (3).

got the sony mw600 for bluetooth audio.. no id tags on display.. on every musicplayer (play music, poweramp, cm musicplayer..) the same.
dont know why, but today even the start/stop, forward and prev. buttons didnt work! the only thing i can use is volume control..
anyone an idea?
Any luck with this?
I want to buy one but couldn't find it in Sri Lanka so planning to order one via ebay & need to check if it works. Running cyanogen mod 10, heard that the bluetooth stack was updated on CM which supports most of the features since stock rom only has older stack version which can have issues!

Wow, maybe I'll wait for a few weeks & see if it works out for you..

Well.. Sound and controll works.. even headset-function works for telephone calls.. only thing not working now is id for tracks
Awesome! Thanks for the reply! I hope it worked out soon!

I also have the track name issue. This is a massive let down. I like to just get in my car and flip through tracks with my phone in my pocket. My iPhone did this, my s3 did this. Why not the nexus 4? Come on Google. Sort it out

my impression is that almost nothing involving Bluetooth functions as it should currently on the N4. I can't even get a mouse to work. what a shambles! it's not as if BT is some new technology. this all better get sorted out in 4.2.2.
If I'm not mistaken Google moved to a new Broadcom b/t stack. Yeah, good move! And I agree, b/t has been around for like what at least 10 years now? You'd think that getting track info should be a given by now. I have a crappy old LG phone running Gingerbread and it has no issues at all.
Bluetooth
When I got the N4, I connected my helmet headset to it and everything seems to work fine. My headset supports ad2p music and phone. Both connected and both worked, including play controls. Not sure about the audio quality, I didn't test it long enough After I flashed Jellybro (CM 10.1 Kang) Music connects, but phone goes on a connect/disconnect loop. Audio needs further testing, can't tell if the left side is off because of the bluetooth or not. Controls work most of the time, every now and again playback will decide to pause itself and sometimes the play command doesn't work. Haven't had a chance to flash stock CM 10.1 nightly yet either.
Play/Pause Works Inconsistently
Has anyone had this issue?
I am on stock 4.2.2, I connect with my car stereo no problems. I use to be able to just hit play/pause on my car stereo and it would just play music from Google Music. Now, sometimes when I hit the play/pause button on my stereo, it won't play. I have to manually hit play from my phone. After initially doing that, then I can hit play/pause and the control is there. I haven't had the problem since I got my phone on Nov 14th, this issue just started to happen. I notice this after installing Light Manager, but I have uninstalled it and still the issue is there. It is inconsistent, but the issue is more often than not.
Thanks in advance for your input.
Just reiterating, stock Android does not show artist/track info, it is not in the protocol, but you can skip tracks or go back to previous tracks. If it is important to you, you should root and get a custom ROM, not sure which ones for N4 has it though, been too happy with stock to root.
About time, Google:

Is anyone else having problems wit Bluetooth audio streaming in car? My music sounds like it's speed up a tiny bit. Kinda like chipmunks voices. Is this a ROM issue?

Hey guys
I'm using my nexus 7 dashed in my car. (Kinda!)
And i'm using tablet talk to connect my phone with it.
Also i have a bluetooth keyboard connected to my tab.
When i have a text, i can answer it easily. But when someone calls me and i accept the call the sound doesn't come from my car audio and my sound doesnt go through my tablet's mic. They bouth go through my phone!
So i have to use my n7 as a bluetooth headset for my phone. Is it possible?
Can anyone guide me?
No one? nothing? no helps? no ideas? cool!!! :|
For God's sake!!!
guys, this will be great. pleeeaaaase, consider developing or sth.
Cool it, seriously. The forum hardly revolves around this one post.
Given the way the Bluetooth radios are set up, it's not really an easy hack and you'd probably have better luck using a dedicated app over Wi-Fi direct or something (of course, such an app would have to exist as well in the first place). I remember looking into this for the iPod Touch a while back and didn't see anything either, but hopefully you'll have better luck.

Well it WAS an easy hack, It's just a case of setting the configuration files up correctly. You get the N7 to advertize the Headset service and an Roberts your father brother as they say. I just about had it setup a couple of months back...... I want to control the full telephony service through the N7 show incoming calls and all the fun stuff.... As a first step I got the voice routing through the N7 Microphone through a handset and onto the caller. However I stopped there because that was using android 4.1.1 and I want to be using the latest build... Which is where your right out of luck because 4.2 onwards is a different beast,
Google decided to replace a tried and tested well documented fully implemented Bluetooth Stack with something that's not quite finished yet whose documentation is the source code. That's why there's no Low Energy stuff on Android yet..... It could and should have been implemented last year, anyway I digress. So the options are
1. Use a rom prior to 4.2 - In which case the Bluez is well documented and this sort of problem has been solved multiple times on the linux desktop and the same ideas can be applied to Android, Google is your Friend
2. put the old stack back in and work with that, There's patches that do that but they are all a bit brutal and would be a nightmare to maintain.,
3. Wait for the Missing Code to be added, which could be tomorrow but It could be never
4. write the code yourself..... Fine if you're an expert in that area but the learning curve is inclined shall we say.
or,
5. You could spam XDA daily with requests .
Personally I put this project to one side because my nexus 7 is out on loan to my brother after he decided to bathe his HTC OneX in Lucozade for an hour...
