[Q] Improved Bluetooth Stack? - Miscellaneous Android Development

I'm using a 7" tablet fully integrated in the dash of my car. i have made my own launcher that suits my needs of an infotainment system in my car. I have navigation, music streaming, video streaming, integration with the cars CANBUS so buttons on the steering wheel works, etc. and it is all working perfect. However I lack bluetooth handsfree. I'd like to be able to answer and make calls (from my phone paired by BT) directly from the tablet. There are several chinese car infotainment systems that can do this. Parrot also does an android "radio" that does this. What do I need in order to support it on my android infotainment (basically just a 7" tablet), I recon I need a new Bluetooth stack?
The tablet is an Ainol Fire 7" running a CyanogenMod 11 rom.

Bluetooth CAR radio with HTC TP

Did anyone try this? I'm thinking of buying a new radio WITH bluetooth..
IF the bluetooth radio stuff works, then tomtom/music could go via my HTC which would be awesome... or is it possible to play MP3's via an USB outlet, or have some auxout to my htc?
A few months ago, I bought a head unit (Dual XHD6425) that has front panel aux out, usb, and bluetooth. I originally got it for its 3.5 mm auxillary out for my ipod, but I then bought the add-on bluetooth module and started using my cellphone and now my Fuze. Bluetooth audio streaming (A2DP) is much more convenient as there are no wires to deal with. The TF3D music program supports AVRC so you can use the unit's fast fwd/rewind/stop buttons to control playback. Tomtom also routes its audio through the bluetooth interface as well. Of course, you also get hands-free calling, which is great as I usually forget to put on or turn on my bluetooth headset when I enter my car.
My head unit could also play music from USB sources (name hard drives, etc, but strangely not ipods). The unit was able to read from the Fuze since it can mount itself as a storage drive providing access to the microsd card. However, in this mode, I'd have to scroll through songs using the unit's interface, which was not very easy to navigate. Still, I can use the USB port to charge/power devices if I needed to do so.
^^^Ditto what he said^^^
My Xterra has a Pioneer single din headunit with built-in Bluetooth. A2DP streaming works great, but sometimes sounds a little tinny or washed-out. If you have added a subwoofer to your vehicle then get a headunit with an independent subwoofer level control. Some songs will be very bassy, while others will need some added punch...this can be adjusted very easily especially with a remote-mount bass level knob.
You can also sync your contacts over to the BT headunits and set speed dials as well as picture dials in some cases. My Pioneer replacement will be a double din 7" touchscreen dvd player with BT. Make sure it has plenty of audio controls/adjustments...digital time correction is a nice feature to help balance sound and set stage.

Bluetooth audio for car?

Bluetooth audio questions - probably rookie-level
I want to stream music/podcasts from my phone (Samsung i907) through my car system. I have installed an AUX RCA setup, so I can now do this with a cable and it's pretty solid.
My question is - are the Bluetooth audio receivers out there - usually relatively cheap - compatible with this setup? Is it as simple as plugging a little BT receiver into my RCA jacks, pairing up my phone, and hitting play?
Any advice/recommendations on receivers/etc. is appreciated. Thanks!
It would help if you state which car / car system.

[Q] iPod USB Emulator... possible?

I am curious to know it if would be at all possible to develop a USB mode to emulate an iPod's USB connection. It'd be a tedious reverse engineering process to see how the iPod pairs with stereos, docks and such, however the outcome would be great considering how Android has no love in the stereo market right now. Perhaps the JVC receiver that will be coming out soon will change this... (http://ceoutlook.com/2011/12/05/jvc-mobile-gets-android-and-gesture-control/)
An ideal application would be to pair with your car stereo, just plug in your phone to the stereo and select the iPod emulator and voila, you can browse your music, play your music, etc. from your car stereo.
Yes, we have bluetooth, but as far as I know you're unable to browse your device on your car stereo using this. The audio quality is probably not as good as a direct connection to the stereo. Just recently I've become aware that it can transmit the song information to the receiver. The problem with this is finding a receiver that supports it, and for a relatively low price tag. Most low-end receivers already have iPod hookups, but if you throw in HD Radio, SiriusXM, Bluetooth, Navigation, or anything else the price will quickly double. You can also just get a simple receive that allows calls via Bluetooth but not A2DP for a lot less.
We also have an audio jack we could connect to, or audio through USB, but you still don't get interfacing as an iPod would (such as skipping tracks, browsing music, play/pausing)
Yes we need android connectivity just like the iPod. Why hasn't this happened yet?
i also was searching for this.
now i use this solution

This is needed
Old thread, I know, but this is an excellent idea. I had thought about such an emulation over the last few years, but had been happy to use DAB radio in my current car. We get a new car this weekend that doesn't have DAB, so I'm left with the old iPod USB connection issue.
I'm no coder these days, but is some reverse engineering of the USB signals not possible? Using bluetooth audio is *some* sort of solution, but doesn't go as far as to allow browsing tracks, albums, artists, playlists etc from my car's interface.
It seems like this is the obvious solution that no-one has thought of.

I've been wanting to do this for years, ever since iPod control in car stereos became commonplace (2006-ish?). That is, build a little box with a female iPod dock connector and a USB port. Plug any USB flash drive or hard drive into the box, and it reads the MP3 files on the drive and emulates an iPod. The iPod protocol is serial and seems to be hacked and documented on the web.

My problem is I don't have the programming ability to write the software for the little iPod emulator box.

[Q] enable a2dp metadata?

Hello,
today I bought a bluetooth module (Alpine KCE-400BT) for my in-car Headunit (Alpine CDE-9882Ri). The device, which apparently uses "parrot" technology is A2DP and AVRCP compatible, streaming music and controlling playback is possible from the Headunit and working fine. However, the phone seems not to transmit metadata to the bluetooth module as the headunit always displays "ARTIST" "ALBUM" or "SONG". I have noticed the same issue in a few of my friends cars, whereas their phones (Sony Erricson, iPhone) transmitted the metadata just fine.
Is there some registry key that enables transmission of metadata? WP7 apparently has support for AVRCP v1.3 (according to http://support.microsoft.com/kb/2449475/de) which has this feature, as does the Bluetooth module, but why is this disabled?

Using a android tv box as a bluetooth player

Hello,
I have a question with which you can help me. Can I use an android TV box (MiniX Neo X8) as a bluetooth receiver (like the Logitech's bluetooth audio adapter). Does it exist any app which let do that?
I currently have the Logitech adapter, which is a very easy and nice way to listen Spotify music from my smartphone, tablet and laptop. Lately, I have been thinking about buying an android box and it would be awesome if I can use it as a media player for the TV and as a bluetooth adapter. In this way, I wouldn't need to be switching the wire of the speakers from the android box to the bluetooth receiver.
In the other hand, is it possible to leave the android box switched on always?
Thank you!
