[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] BlueTooth & Cars

I've tried to connect my phone via BT to two different cars and have no luck. It will scan for devices but won't find them at all. Does this happen to anyone else with the SIII? Strangely enough, it finds and connects to my JamBox is just fine.

What ROM are u on ? Stock or rooted?
What kind of cars I know my Audi A8 will connect but I always have to connect manually and enter the 1234 paswrd.

Still rocking the stock and unrooted for the phone. I tried on a Lexus GS and a Scion xB but no results show up. How do you connect manually? I should try that

Phone calls and bluetooth streaming works fine in my 2009 Mazda 6 (GT, no navigation). My phone is stock + root.
I use Slacker Radio everyday, launched by Automateit Pro when the connection to my car is established.
IIRC, I had to input a PIN on my phone, then in my car to do the pairing, and after that, I had to connect the phone manually to the stereo, but only once. After that, it's automatic when I start the car. Watch out for the "Only visible to paired devices" setting on your phone. It must not be checked.

I too have major issues with bluetooth, my phone connects whenever it feels like. I had to flash to cm9 to be able to listen to music in my G37. No problems in my other car (it has aftermaket pioneer system).
PS Just flashed the CM10 since they finally figured out A2DP, but the image is broken. (Note to myself: "Read the thread before flashing") Will wait for the next nightly build.

Nissan's always had a horrid BT stack in it. I'm in an 09 Altima and BT just sucks. I know it's not the phone as I've tried multiple phones from multiple vendors and they all suck. Nissan won't fix it either.

[Q] Bluetooth issue with Cars
I have AKOP Rom and KT Kernel. My bluetooth connectin to Mazda Cx-5 is fine. However, the problem I have is a lot of phone information (Song title, Battery Status) I used to have on stock, now are gone. Previously, I can fast foward or Rewind a song, also, once BT is connected, the default music player will start automatically
Can someone suggest a BT manager app which can change and enhance BT setting?

I have a 2009 Mercedes B200. My phone connects to the car just fine, but no sound comes from the speakers and no sound goes into the microphone. Same thing with my car and the HTC One X, although that was fixed with a stock ROM update. Bluetooth on cars can be very hit and miss.

[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.

Must be the diesel, lol.

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]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.

I need help understanding how bluetooth works on these MTCB HU's.

I've searched and looked, and I can't seem to find a complete answer to exactly how the bluetooth works on these things.
As far as I can tell; there is the native bluetooth manager that's built into Android, and then a Bluetooth app. Seems like the app is used to make calls and stream from the phone?
I've also read that there cannot be an OBD2 sensor and a phone connected at the same time? I remember reading somewhere that's because Android doesn't actually handle the bluetooth itself, so if I were to get a bluetooth dongle, would that fix this?

FYI, I have a joying headunit and I have been using the Torque app w/ a Bluetooth ODBII adapter and received calls while both are connected. But yes the Bluetooth profiles that come with these units are very limited and basic.

What is your process in getting them to work together?

I remembered that I had another BT OBD2 adapter. I was using this one and couldn't get it to work, https://www.amazon.com/dp/B011NSX27A/ref=cm_sw_r_other_apa_F0mqxbPZDQSQ5
I then pulled out my old one, (not this exact one, but looks identical) https://www.amazon.com/dp/B00EQ57BE8/ref=cm_sw_r_other_apa_b8mqxbA6SEVRV and now they both are working together.

Is it possible to get DashCommand working on these units? I like it better than torque.

Sure no problem, and what I did is just buy a self powered USB hub and stick an additional Bluetooth dongle in there (android compatible, costs about $4) and pair with both.
Never had a problem with any of them

Hello,
The BT module in these devices are not an internal device, rather an external BT chip. There is no direct data line between device and BT chip. Basically they send commands and share metadata over serial port. Thats all about so dont consider it is a native bluetooth device.
