[Q] Maximum simultaneous bluetooth connections

Anyone know how many bluetooth connection the GNex can handle at once? For example, I'd like to play GTA3 using my PS3 controller via Sixaxis and listen to the audio using a BT headset.

Just give it a go.. If it works or not report back to us

Nope, doesn't work. Turning on Sixaxis kills other BT connections.

i've been always under the impression that bluetooth only allows one connection at a time. only support i have was connecting my nexus one in my dads car listening to music, and then trying to answer a call with the bluetooth headset. apparently the headset had disconnected when i connected to the car.

[Q]A2DP on CM 10.

I'm curious as to how to set up bluetooth audio. My car supports it (Jetta TDI 2010). When I connect with bluetooth I can't seem to figure out how to use it. This is my first android phone and I've never used bluetooth audio before.
Just looking to be pointed in the right direction. Google hasn't been too helpful.

I believe cm10 has ad2p, I know AOKP does.

I'm not sure I understand what your problem is?
You can't figure out how to use bluetooth in what way, exactly?

When my phone is connected to my car via bluetooth, I cannot get the phone to stream audio, nor can I get the car to recognize that the phone has A2DP capabilities (I know my car works, I have the bluetooh audio connection and my friend used it with his droid)
I'm just not sure if I'm missing some small important piece to get the audio streaming.

So the phone call bluetooth works but not the music bluetooth?
Go into the bluetooth settings for your phone. And make sure both checkmarks are checked, one for phone and one for audio. You'll do this by editing the bluetooth connection to your car.

[Q] Bluetooth Auto-Connect?

Quick question whether there is an app, mod, or even build.prop edit that would allow my Note II to automatically try to connect to my car's single din Kenwood KDC‑BT952HD. Only thing the head unit tries to do when connected is re-download contacts, but it turns on as soon as my car turns on and it'd be a lot faster if my Note automatically attempted to connect to the head unit instead of the bluetooth popup with listed devices, which I don't even have considering I'm running Whompasaurus V2.9. so if there's any way I could even get the pop up that'd be great too!

I use Tasker to turn on Bluetooth and connect to my earpiece. But I need a trigger and I need to turn on my earpiece. The trigger I use is activating my map app.
So without a trigger, I don't know how to do that.

I'm new to tasker and I'm not sure how to enable the auto-connect through tasker.

I am new to Tasker too.
Task / Net / Bluetooth
will turn on/off/ toggle Bluetooth
Task / plugin / Secure Settings (separate app) / BT Connect
Will connect to your chosen Bluetooth device.
My best advice is to play around. Also, here is the first of a 3 video series on Tasker.

maybe I'm missing something here, so may suggestion by be complete off.
Maybe leaving BT tunred on your GN2 before you get in your car. Or turned it on before you get in the car. I'm assuming the ROM you're using has a BT toggle. The thinking is that your headunit will try to automatically connect to any paired BT devices. If so, the GN2 should automatically connect when the deck does it's search.
This works for me when I try connecting to Jawborn Big Jambox or Jawbone Era or other BT devices I have paired on my GN2. It may be worth nothing I'm on a deoxidized stock rom. But I this also worked when I ran AOSP roms on my Evo 4G such as CM.
If the headunit does not do a pair device search and connect when it turns on, then I would definitely try suggest above. I have no clue, and that's better than nothing.

no autoconnect on GN2
Once you had a BT connection with your car and leave it at the gas station e.g. it won't reconnect when you're back!
Sad, but since then I tried the mighty Tasker and similar apps, but was happy with the app called "Bluetooth Auto Connect".
You can define the simple trigger, when display on....
So whenever I get back into the car, I hit either the menu or start button, that's it. Without unlocking you are back connected.
The only other annoying thing that you might be able to fix with Tasker is, that right after the A2DP establishes the connection the player starts playing the last song, which I obviously don't want most of the time.
Also Play Pause Next etc over BT doesn't work too well on android.

I have a Alpine head unit and as long as my bt is on before I start the car everything syncs automatically.

I have a Kenwood Dnx6980, and my experience has been that once my phone has been setup to sync ... The Kenwood will talk to it automagically.
This is using AOSP or non stock roms. Ofc.

Guys I have a Chinese brand double din...MobileVision...or something like that and using Tasker along with Bluetooth autoconnect worked for me. The posts above describe exactly how to set it up and it worked for me.

Bluetooth autoconnect's main feature works for my xperia pro (turn on bluetooth, connect to your selected devices in automatic)
Bluetooth autoconnect's tasker plugin is not working for me. I can use it, sort off, but it does nothing. Like, "Press the button, but there was no reply!"

Well that is odd. I have a Pioneer unit and my phone connects to it as soon as it detects it in range. Even if I turn off BT and then power it on, the phone automatically connects to the head unit without any intervention on my part. Sounds like an issue with your stereo.

No stereo issue. On some of the touch wiz based roms bluetooth DOES NOT auto connect. On most (if not all) aosp roms bluetooth DOES auto connect. Currently on ma7 stock with root and it auto connects. When I was on whomp, jellybombed, and labrats

Bluetooth Connection
Hi Guys,
Im glad i found this thread, im wondering if anyone could help me out.
My scenario is, my bluetooth is connected to my car radio playing files. When a call comes in, i need it to disconnect from the car radio and connect to my bluetooth headset, all without turning off bluetooth ( preferable )
My possible solutions are:
1 ) By using automagic, ive managed to get alot done with this app, but this seems beyond it.
2 ) Getting automagic to start an application when a call comes in which will force bluetooth connection to a specific bluetooth device and disconnected from other devices.
Anyone got any suggestions?

not sure of your rom, but both TW and CM allow you to set whether each connection is Media or Phone. put your headset to phone and your car to media only. when you answer the phone the headset should take over.

Could you share how you did this? I am completely confused by the interface.
I am wanting the same setup but also for music player and Pandora
I haven't found an example to follow that even comes close.

Still not sure how to set the trigger however.

The first few minutes of that video answered my questions.

[Q]Connecting to multiple Bluetooth devices

I just started going back to the gym and I use Bluetooth headphones with my note 2. I'm debating on buying a Bluetooth heart rate monitor to use with a couple of workout apps to track my calories being burned.
I'm wondering.. will I be able to connect both devices simultaneously?

In the car I connect to my head unit, cobra iradar and obd2 scanner. So I don't think you should Have a problem

how....as far as i know....one connection can be made at a time; as soon as you connect one BT, the other got disconnected.
just like wifi and hotpost; your phone either is on wife mode to get internet connection from other or your phone is on wifi-hotpost mode to provide internet connection to others

You can simultaneously connect and use the devices only if they use different BT Profiles. For example, I routinely connect the Note2 to my car's BT receiver for phone calls (Hands-Free Profile, HFP), MP3 playback to the car's speakers (A2DP), and navigation using an external GPS device (Serial Port Profile, SPP). Works fine.

[Q] Bluetooth issues in a vehicle

Hi everyone,
Got my black Z1c yesterday, love it so far!
However, when I try to use it in my car (Audi A6 2008), I cannot place a call if it was initiated from the car's interface.
The phone connects to BT no probs and shows my car in the devices list as a headset. Incoming calls are reflected on the car's display, and connected to the speaker's/mic of the car. When I place a call from the phone itself - same deal, all works as expected. But when I use the car's controls to dial a number, the car's display shows "connecting", and nothing happens...
Tried to pair/unpair many times, no success. Tried other phones, like iPhone 5, Samsung Ativ S (WP8), Samsung Galaxy S4 Active, HTC One - all work seamlessly. My old Xperia Z was working fine, until I sold it to get the Z1c... I would never expect Z1c to behave like this...
Anyone has similar issues?

Yes mine is the same (ford sync)

Bluetooth is a wireless protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks.
There are two important parameters of Bluetooth devices - class and supported profiles.
"Class" signifies the distance at which a Bluetooth connection is possible. Most mobile devices are Class 2, which means they have a range of up to 10 m. Class 1 devices are rare and have a range of up to 100 feet.
A "profile" is a type of Bluetooth connection. The most common are the Headset (HSP) and Handsfree (HFP) profiles that enable the device to connect to a wireless headset or handsfree.
Some other profiles are OBEX (OBject EXchange) which allows transfer of files, contacts and events; A2DP, which adds support for streaming of stereo sound and AVRC, which allows remote control of playback.

try clear caches. All kinds of caches. When I say all kinds, I mean all caches that you can clean. Retry what you want to do. If it does not help, try factory reset and retry your bluetooth connection. if it still does not help, try flash firmware. I guess this is the solution you can count on.

Thanks, will try. The phone was just outta box when I was trying it in my car... The car was the first BT device it has ever been paired wtih...

Phone calls work fine on mine.
BUT while we're on the topic of vehicle BT, has anyone got working song info via bluetooth? I thought it was supposed to support avrcp 1.3, but in my car (2013 Ford SYNC) I still get no info about songs I'm listening to and also the voice commands for playing artists or albums don't work.
/Daniel

I use it with my new Golf and the phone functions works as expected but the song info does not show. But they never do with Android phones. My 5s works of course

In my Toyota Auris 2013 model song info always worked with Walkman app assuming you have tags filled out correctly.
I know there were some issues with tag info in Poweramp I prefer to use but they got that fixed recently. Advanced options to display song info on external BT device is just buried deep in app's settings though.

Everything works fantastic on my BMW F10 (2012) with Navigation Professional, Bluetooth Music with Song Info, Phone with contact pictures (! Didn't even know that was possible until I got the Z10c) and full Message Access Profile with historic E-Mail and SMS access.
The In-Car integration is the main reason why I am torn between iPhone 5s and Xperia Z1c.
The iPhone has the Advantage of "BMW Apps", which allow using Webradio, Facebook, RSS Feeds etc. through the Navigation, as well as iPod Control and Coverart Display.
The Z10 can't do those things, but it can do Bluetooth MAP which is rather important to me also. Webradio can of course be streamed via BT (and controlled on the phone).
