[Q] New Bluetooth Stack in 4.2 - Samsung Galaxy Nexus

New Bluetooth stack
Android 4.2 introduces a new Bluetooth stack optimized for use with Android devices. The new Bluetooth stack developed in collaboration between Google and Broadcom replaces the stack based on BlueZ and provides improved compatibility and reliability.
Does anyone know what the exact improvements are? I remember in ICS there was an issue with degraded audio quality when you had two bluetooth devices connected (ex: hands free car speaker, and audio streaming device).
My car only has phone support (no A2DP) over bluetooth, so I am looking into buying this in order to stream music. Ideally the phone can know when to send a call to the car and music to the aux plugin.

New BT apps allowing streaming HighQ MP3 towards BT headsets

I own a Bluetooth Motorola headset HS810.
I also own:
- a MDA compact
- a MDA III and
- a XDA II
I see that recently someone was able to USE BLUETOOTH NOT ONLY for receiving phone calls, but also for listening to MP3 and other sounds or musics (via Windows Media Player).
My GOAL IS TO USE my BT headset and HAVE THE SAME QUALITY THAT I CURRENTLY HAVE USING STANDARD HEADPHONES.
Now what about quality? I heard about ADSP, a new bluetooth stack which allow much higher sound quality, quasi-stereo quality.
My questions are:
1. can somebody please summarize what is the current development status? Can somebody clarify this subject to unprofessional and amateur users like me who are eager to use BT headsets and listen to MP3 (not only pick up phone calls)?
2. If this new BT stack (widcomm or toshiba or microsoft ?) is already available, then in which units can be implemented? MDA compact? XDA II? MDA III?
3. Supposing this new BT stack already exists and it enables Windows Media (or similar applications) to stream sound for BT heeadsets, THEN can I get “quasi Hi-Fi” sound quality with my current Bluetooth Motorola headset HS810 or shall I need a replacement, a better BT headset a new generation one?
Thanks for your kind suggestions

[Q] WP7 Bluetooth Support

Just wondering what bluetooth services people are seeing on there WP7 phones.
I have a HD7 on T-Mobile USA and it's only advertising the following to my Windows 7 computer:
A2DP
Headset Audio Gateway
Remotely Controllable Device
Thanks
a2dp as a service for the phone? not sure, but my friend bought the hd7 on my recommendation and he can't get audio for video files through a2dp and its killing him
hopefully wp7 has some cool tricks up its sleeve based on what you got there
I'm interested in four bluetooth profiles, if and how they are compatible and work.
- A2DP
- AVRCP
- Handsfree
- Bluetooth HID for Keyboard
any news mostly about the BT HID Keyboard?
I found this on Microsoft Support site:
Windows Phone 7 supports the following Bluetooth user profiles:
Advanced Audio Distribution Profile (A2DP 1.2)
Audio/Video Remote Control Profile (AVRCP 1.0)
Hands Free Profile (HFP 1.5)
Headset Profile (HSP 1.1)
Phone Book Access Profile (PBAP 1.0)

This is the first device I have seen that supports SMS over bluetooth. If you have a Ford product with SYNC, you can use SMS over bluetooth. It also works with my Kenwood head unit. Basically, you can see incoming messages and, in the case of SYNC, send canned replies from the head unit. On my Kenwood, there is actually an on-screen keyboard to send any message you like. Cool stuff really!

same problem with my htc trophy. audio for video files only plays through the loud speaker and not through the bluetooth headset. I tried the blueant q1, jabra stone and jabra extreme with the same results
i have a Samsung Focus and i am having the same issue with no BT audio from videos. i tested the HTC Surround and LG Quantum at the ATT store with the same results. i am using a Jabra BT3030 which worked perfectly on my Microsoft KIN, audio streamed and play controls (Play/Pause/FF/RW) worked.
A2DP
Does anybody know if an A2DP video fix is coming up in the NoDo update? I'd say it's way more important than copy-paste, but regardless of importance, it is an important feature.
Any news?
noone knows outside of MS as far as i'm aware. we only know about copy/paste and app performance improvements because they told us. only time will tell if they actually fixed the issue.
hands free car kit and voice activation
When my LG is linked to the Bluetooth hands free car kit (Landrover) the voice activation doesn't work.
It opens but it doesn't "hear" anything
Since this is about the only time i actually need voice activation it's a bit annoying
Anyone have any ideas?
I totally agree about this bug. Who the F cares about copy and paste? How about turn-by-turn navigation for Bing Maps like was released last year for WM6.5 ?

Bluetooth version & BMW music streaming

I wondered if anyone can help with my query regarding getting music streaming to a BMW 320ED via Bluetooth?
The good news is that I can get my Galaxy Nexus (GSM 4.1.1 stock software) to pair with the car and I can get music playing via Bluetooth, but I can't see the artist information. The car screen informs me that the device doesn't supporting sending track information, or something along those lines.
What frustrates me about this is that my friends iPhone 4S does stream the track information as well as the actual audio. I Googled to see what Bluetooth version both phones use, apparently the iPhone 4S is Bluetooth 4.0 and the Galaxy Nexus has 4.0 capable hardware but only 3.0 features are available due to software limitations.
Is this true? Is once of the differences between Bluetooth 3.0 and 4.0 the ability for track information to also be shared? I was using Google Play Music if that makes any difference.
I've done some more research about this and thought I would update my post, just in case it's of help to anyone facing a similar issue. Turns out the Bluetooth protocol/profile AVRCP is responsible for streaming music tags to the car stereo, but only AVRCP 1.3 and above. Unfortunately the Galaxy Nexus only supports 1.0 by default but CyanogenMod 10 has built in support for 1.3 since roughly the 14th September nightly.
Should be able to test it out next week at some point. Why are Google so bad at supporting the latest Bluetooth features? I've always found this with Google experience devices to lack in this area where other manufacturers support the latest Bluetooth features.

iphone bluetooth receiver with apt-x

i have a mini cooper, and it supports Iphone docking. it also supports msc drivers, but with newer android phones, MSC isn't really available.
anyway, i just realized there are devices that basically (Bluewave Bluetooth Audio Receiver) that emulate the iphone, but gets it's signal via bluetooth. so i can pair my phone to it, which would in turn relay the audio to my car...and hopefully, my car would think it's an iphone, and all the corresponding features would still work.
has anyone had any experience with these? would i be able to control my phone audio via my car's control? would the headset display song titles?
anyonw know one that support apt-x?

Best bluetooth support AOSP rom?

I'm currently using AOKP and am having issues with stability when using Pandora over the Pioneer link to my new head unit. It works, but if I try to skip a song, my phone freezes up and eventually reboots itself. I'm pretty sure its because of issues with these protocols support so I was wondering if there was an AOSP rom that has really good bluetooth support. The protocols it needs is:
A2DP profile for audio streaming.
AVRCP profile for audio control (track metadata available on 2013 and 2012 AVIC and AVH models with AVRCP 1.3).
SPP (Serial Port Profile) for full, on-screen control of Pandora® internet radio and Aha™ Radio (for Navigation receivers)apps when installed on Android device. Please check the owner's manual of your Pioneer receiver to verify compatibility with the Bluetooth SPP profile.
Does any of that make sense? Would I have better luck with just standard CM10?
