Wireless Android Auto - PCM audio or Bluetooth? - Android Auto General

Hello,
When one uses Android Auto over wireless does it stream audio with PCM (44Khz, 16bit) like a cabled connection or does it fall back to Bluetooth? I haven't been able to find a clear answer on this one.
Thank you!

Does anybody know of an alternative/more suitable forum I could post this question?
Thank you.

stream stereo bluetooth without A2DP or any accessories

Has anyone been able to play music on their car's speakers through bluetooth specifically lexus with navigation, LEXUS GX 470 with tilt?
I've tried lots of things to get this working and the only thing that works is the calls but the music doesn't stream over.
Ive read and read everything on here the only advice i see going around is buying more accessories, I want to make this work
without having to buy any bluetooth adapters like jabra or jawbone, i have so many different accessories that i can build a spaceship
and don't want or need anymore. Thanks in advance
Does your lexus support A2DP? If not, then no, it won't connect for streaming stereo audio. Looking at the Lexus web site implies that only HFP is supported.
You can look at the JETWare BT Extention driver.
Tried a lot of different things and hasn't worked isnt there a way to make the phone transmit the music as if i was on a phone call, there has to be software out there that does this.
nope.. havent tried it with that.. but works perfectly with a BMW 528 i flawlessly
( check the kaiser pic thread to see what i mean )

tried with the above mentioned Lexus..
i own a BMW 528i so i can speak from experience when i say that it connects flawlessly.
and the thread im speaking about is just a picture thread dedicated to pics uve taken with ur kaiser..
but if u must.. http://forum.xda-developers.com/showthread.php?t=371647&page=15
I must be a dunce but i don't understand what the picture thread has to do with it.
EDIT------
Oh that you actually own the BMW, you could of just linked me to your post. http://forum.xda-developers.com/showpost.php?p=2275428&postcount=145
That's a pretty big thread which would have been hard to find without the exact name.
BMW and lexus are different cars, your probably has A2DP (does it?) where as mine doesn't. Anyway your car is newer.
Check your car user manual. If it says Bluetooth 2.0 (or at least 1.2) with A2DP, then the answer is YES; otherwise, you're wasting your time.
I have RX350 and its bluetooth is 1.0; not sure if Toyota are so generous that they install bluetooth 2.0 w/ A2DP on GX470
You know its funny if you google "LEXUS GX 470 bluetooth a2dp" without the quotes this thread is #2 & #3 right after the lexus website, and you responded literally 2 minutes ago, google sure is working fast.
I don't have the manual, and i don't think it has A2DP anyway.
I'm going to try 2 more programs let you know how it works out.

Well Blue music didnt work. But i did hear my music ringtones. Bummer. All I got left is Chartcross Bluetooth Audio Router.
http://www.teksoftbluemusic.com/
Bluemusic is the only software available that offers Voice-over-Bluetooth combined with 100% phone support. People all over the world are now familiar with the expression "Music is wireless!". Starting with version 2.0, not only music, but anything related to AUDIO playback goes WIRELESS with Bluemusic! Make sure you get your own copy today!
It should work according to their website quoted from FAQ page.
3. Will BlueMusic work with the A2DP profile of my Stereo Bluetooth Headset?
BlueMusic is not intended to be used with stereo A2DP headsets, but with the mono bluetooth model headset. The reason is that with the stereo headset you can listen to music from your mobile device by default, but with the cheaper, mono headsets used only for phone calls you can't. So BlueMusic only offers missing functionality for that type of headsets and would be useless for the stereo A2DP. Still, feel free to download the trial version and try it on your device.

how to "speed up" a2dp / bluetooth. HELP!!!!!

I need some serious help please.
Situation: My car has bluetooth for phone but not music. So i bought an A2DP FM transmitter. I am trying to use both in the car. one for phone, other for music. problem is, when both bluetooth devices are connected, the music SKIPS horribly.
I've tried a bunch of different roms and radios and tried the a2dpfix and everything I could find.
Basically, when i disable the car bluetooth, the skipping stops.... so it's the radioload or the workload on the tilt that makes the music skip.
So......
1) what can i do to increase bluetooth performance or general system performance?
2) what is the best rom or radio for bluetooth performance?
3) what is the best setting for bluetooth performance in registry? bitpool? framerate? jointstereo?
4) what is the music player using the least amount of resources?
THANK YOU. Please help with knowledge, not speculation.
also, any thoughts on prioritizing bluetooth devices or signals to give higher priority to a2dp?
overclocking?

Most likely. Several people have reported that issue. A2DP needs lots of bandwidth and realtime availability, if a second connection needs to be maintained at the same time it's very likely to cause interruptions.

What I did to fix this problem was to purchase the new Motorola FM transmitter - it does BOTH on one device - it transmits music to the radioo and gives you hands free for phone - really works well - much better than the Parrott that was in the car to begin with.
Bill
I saw the Motorola FM Transmitter but decided to go with my Satechi model because 1) it starts up automatically with ignition and 2) I can hide it away in the glovebox instead of having it attached to my visor.
so the best set up was to use both at the sametime but i'm not sure if i can anymore.
anyone know how to dedicate more resources to radioload or set priority in task manager?
THANKS
No.
A possibility, which depends on your Satecho thing, is if possible not to connect it to the Kaiser (leave it on, paired, but don't expressly connect to it when getting in the car).
That way there's no active BT connection between teh 2 so you shouldn't get skips. When you receive/place a phone call, the Kaiser will search for a present known handsfree and connect to it automatically anyway.
how do i pair it and not connect? when i get in the car, the car handsfree connects automatically.

Did you happen to do any registry tweaks to maximize the performance of the A2DP BT Stereo performance in the past by increasing the Bitpool and MaxSupportedBitPool DWORD. I found on my Vogue that I lost simultaneous BT connection when I altered those settings from default. I now leave the registry A2DP settings at default and have not had problems with simultaneous BT connections (hands free, BT stereo and BT GPS puck).

Have we got the possibility of Bluetooth

from the G1 running webradio (WiFi) to a BT monaural headset?
i can't seem to find out if this is possible with this equipment yet or not. i understood it to be possible when i bought the phone, but am still trying to find out how.
Any help would be really appreciated. Have a great morning!

Mono headset? As in a telephone headset?
Not likely, unless your headset supports A2DP.
A mono telephone headset is different from an A2DP headset, and isn't compatible with music playback. This is a limitation of your headset and not of Android. If you have some other phone where this *does* work, then that device is in violation of profile specifications -- it is NOT supposed to do that.
O.K. My bad. Thanks for the info. What i have is a plain ole BT. It seems to work o.k. with the phone but i'm trying to find out if i can get the G1 to broadcast the music coming from a WiFi station instead of the phone's speaker.
Have a great afternoon!

[Q] Bluetooth - A2DP missing.

Hi all,
I have just bought a Bluetooth car kit/audio streamer. It pairs o.k. but is only showing up as a car kit - suitable for answering the phone only. Is there any way to add the A2DP profile to this device? I know A2DP is setup and working o.k. because I have already one device that works just fine for streaming audio. I have deleted this just in case it was conflicting but this did not help.
Anyone got any ideas what to try next ... Google is not much help on the matter?

[Q] DIY Car Project

Hi Everyone,
I've been looking all over the net for some answers for a DIY Project i'm trying to do.
Basically I want to have buy either ChromeCast or EzCast and connect to my cars AUX double din head unit to mainly mirror Pandora from my Android Mobile (Sony Xperia Z).
The questions I'm hoping to have answered are the following;
1. Can I use ChromeCast or EzCast in my car without being connected to a wireless hotspot or network? Being a car setup, I wont have a hotspot in my car, unless a LTE/4G Dongle, which I don't intend to.
- Will they work by just directly from my Mobile to the Cast dongle?
2. If mirroring Pandora, will the music or the head units display stop when I turn off my Mobiles display? (I dont want to constantly have my display on as that will drain my battery)
3. Which is better EzCast or ChromeCast Dongles?
If someone would be so kind as to answer the above questions for me, I would be greatly appreciative. :good:
Thanks
Not Chromecast - Chromecast requires Internet connection because it's designed to pull content from the Internet.
No. In the cast of Chromecast, Chromecast itself is the device requesting the stream and playing it. Your controlling device is only a control and can be rebooted, disconnected, turn off, etc.
In this case, given your requirement of not having a hotspot/Internet, I would say not Chromecast. I don't know if EzCast is appropriate, so I'll leave that to others.

THIS!
He would be much better off just getting himself an LTE Nexus7, finding a way to mount it that is convenient and wiring it into the Audio system Aux Connection directly or installing a BlueTooth Audio Access point to that aux input that the Tablet or phone can connect to.
Many of today's better Car stereos have an Aux input that will override the input currently selected on the AV unit for use with GPS when it detects an audio signal.
And by dong this you can use the Tablet as a GPS unit as well!
More expensive but you will need the tablet or phone to control the CCast anyway doing what you want to do....
You could just buy a mount that is wired correctly and use your current Phone or Tablet to do this.
Or buy a tablet specifically for this purpose.

Thank god! Cheers guys for the helpful responses, you just saved me alot of time!
Thing is I have an Alpine INA-W900BT head unit, it has bluetooth, it has GPS, it plays videos(not that I've ever used it lol), reverse camera video and the main thing is it sounds amazing! As an amplifier it reproduces great audio. A tablet can't give you that sound clarity and control with the cars audio system/sub.
Annoying thing is BT audio stream though AUX leaves me with a blank display, so I figure i'll try to "cast" it. Atleast this way I should be able to see pandora on the screen.
Maybe the next car i'll do the Tablet DIY similar to this fellow, don't want to spend to much cash on this right now;
https://www.google.com.au/url?sa=t&...xXpXfPR6d9YTlrC62eKMkGw&bvm=bv.69411363,d.c2E
For now, just want to mirror or local cast somehow. You're right though, end of the day I'm still going to have to control it with my phone...
Maybe get a Android Smart Box hmmm....
Does anyone know if Ezcast requires a hotspot?
Why don't you use MHL?

Well unfortunately that unit is made more for Apple not Android....
If you have an Apple device and plug it into USB I believe it will display video for control of the device to the screen. But it seems to be limited to iPod and Music storage and makes no mention of things like Pandora. It would appear from the description that plugging in via USB turns the iPod or iPhone into a storage device that the AV unit then loads files from into it's native music player.
This seems to suggest that no matter what you try to use, you will not get control or anything but a blank screen when streaming it as it will all have to plug in via the Aux (even if you don't go BT).
The limitation is really how do you get the audio into the AV unit..I'm sure it has no HDMI ports on it,
And any Audio Breakout you use is going to connect to an Aux port.
This unit you have appears to be just a generation before mobile data in the car was expected....

Contrary to what has been said, this can be done, or say at least I did it and I am waiting for someone to reproduce my results and confirm.
You can stream from your phone directly to your chromecast, provided you activated the mobile WiFi hotspot of same phone (no need for an external router).
