[REQ] Phone --> Bluetooth Speaker

Ive been searching around but cant seem to find any apps that would do this. seems to me like it would be quite simple to do. anyone know o something similar to able to quickly put something together?
Main reason at the moment is that i currently have a long wire diagonaly across my room to connect my laptop to my speakers. I just thorght it would be realy good if i could plug my phone into my speakers and then send music to it via bluetooth. Im sure other people have been in this situation where an audio cable has not quite been long enough.
Might be a bit harder but possibly this could work over wifi too and would be able to work from room to room. I expect this would require a pc client though..
any thorghts?

I would love to have something like this. The phone would behave like a bluetooth speaker or headphone (A2DP). This would be fantastic. I was looking for something like this a year ago, I thought I would find a software which helps me do this, but I was unable to find anything then. Maybe we can find something now.
I could try developing such a software if there is not anything of this sort already available. I would be glad if any experienced developer can provide us some starting points, keywords, etc., which would speed up the initial activities.

Use UPNP media server
the simpler solution is to use unpn media server over wifi networks
like twonkys media server. or xmbc
basically the computer where the files are stored will server the files to any network attached device including HTC through webbrowser.
I have my dish tv /Satellite decoder connected to home pc using vlc and watch the tv on my HTC HD using VLC
for sound files i directly load them over network disk

Bluetooth Audio Receiver
I've got a TV which supports bluetooth headphone. With such a software, I'd be able to use my HTC HD2 as a bluetooth headphone. This should turn the phone into a bluetooth audio reciver, rather than a transmitter.
I've been looking for this software for ages and appreciate any ideas.

yea this would have been good. was halfway through downloading xmbc when i realised it wont work in my case.. im at university and the wireless has some security issues that wont let it connect to my phone
also wireless drains quite a bit more battery than bluetooth and would probably have to plug in the phone each time you do this.
some great links though, now we need some bluetooth ones!!!

Is this what you need?

Let's see if I get that right:
You want to send BT stereo audio from your BT-enabled laptop to your phone, and plug your phone into speakers for audio output. Right?
Might be easier to get a bluetooth receiver for your speakers. There are some for your home audio system (e.g. at amazon).
What I did was get a stereo bluetooth headset receiver. You can use it as a bluetooth headset (in your car, on the bus, wherever) OR you can simply plug it into your speakers. Just be sure to find one with a 3,5mm plug (and not wired-on headphones) so that you can use your own headphones or plug in your speakers. There's a choice of fine receivers from
Nokia (BH-214, BH-500, ...)
SonyEricsson (HBH-DS205, HBH-DS980, ...)
Jabra (BT3030, ...)
or you can try and get a cheap but great one from the itech clip series.

no, I dont think so. thanks for the suggestion though!
we arnt trying to get sound from the phone to a bluetooth speaker but instead turn the phone itself into a speaker whcih can recieve audio from other bluetooth devices.
for example if watching a film on my laptop, i would like to plug my phone into my speakers, connect up the bluetooth, and watch rather than running a cable to the speakers which are a long way away.

Nik, you bet me by one...

to be honest ive actualy already ordered this:
http://shoponspot.com/bluetooth-20-a2dp-avrcp-stereo-music-receiver-and-handsfree-black/
I still would like to see this app developed as i can imagine future situations where this happens and i dont want to have to carry this around everywhere.
also people with bluetooth tvs im sure would prefure not to have to use another device all the time and occasionaly you get bluetooth headset transmitters in public places where this might be useful.
hope it is possible!

ooo wow! im a senior member now!!

well i received my bluetooth headset but unfortunatly it charges through the 3.5mm headphone jack so i am unable to leave it there to just work
Ive also tried plugging in a headphone splitter but it realy dosnt like that!! so that means every time i leave my room i will have to put the reciever on charge and every time i return i will have to turn it on and plug it in.
does anyone know if it would be possible to get the phone to work as a bluetooth audio reciever? seems like something it should be able to do

I'd like to bump this because I've been searching for ages for exactly this. I'd personally like to go one step further and have a client that would support A2DP and the handsfree protocol. The latter I would like to allow me to answer and initiate calls to my work mobile using my HD2 as though it was a bluetooth handsfree kit. Then I could use one phone for all my calls.
I can imagine a wide range of useful applications that other solutions like wifi audio streaming or a dedicated bluetooth audio receiver wouldn't match.
I wish I knew how to write software... Maybe if I ever have a few hundred hours of spare time on my hands I'll learn and write an app to do this.

i also want this.
please anyone help.

This would be great.. i currently have an nvidia shield tv and I can plug my normal wired headphones into the nvidia shield's bluetooth remote. The problem is the remote's battery life only lasts a few days when used like this. I would love to be able to use my mobile phone as a back up for when the nvidia remote battery dies. For some reason the nvidia remote won't charge unless my head phones are unplugged.

Car Stereos with USB

Does anyone have a car stereo with a USB port? If so can you elaborate on what that is like to use? I am purchasing a new unit and that feature is one I do not truly understand. A few questions I have are listed below, but feel free to add anything else you think might be useful in making this decision.
1: Does the phone charge while connected to a USB port on a stereo?
2: Can you use the file system and player controls through your stereo or do you have to control the music and other audio through the phone itself?
3: Does the audio work from all sources with a USB connection(for example phone calls or turn by turn), or will it only play music player audio?
4: If you do have access to the file system from your stereo, will it display song titles and artist info etc? How cumbersome is it do control this way?

It would be helpful to know what actual head unit you're getting. But I will try to answer most of the questions as best I can since I have a fairly new Pioneer HU.
1. Yes, but it only charges on "USB" mode, not "AC".
2. Yes and no. The Pioneer HU that I have does NOT support MTP mode (which is what Jelly Bean, and I believe ICS) uses. Basically MTP is the protocol for storage on the Galaxy Nexus. If you can find a ROM or Kernel or any way to change the mode to "Mass Storage", then you'll be able to browse the file system.
3. Only music (or whatever else is inside your MP3 file). When you connect to your HU through USB, your phone basically turns into a flash drive. From there you have to navigate to your "Music" folder and tell it what to play. The only way to do calls, navigation and music at the same time is to use Bluetooth or a 3.5mm cable with an inline mic.
4. It displays what is inside your ID3 tag inside the MP3 file. So basically, if you have all the info filled in, then yes, it will display it. As far as how cumbersome it is, it takes some getting used to, but not to bad (on Pioneer, I have no idea on any other brand).
Short answer: Unless your stereo support MTP or you can find a way to force "Mass Storage" (which I'm not familiar with a way how), your stereo will only charge your phone. It sucks, but that's the way it is.

Pioneer has the app radio which will control your phone and also allows you to use Pandora on the actual H/U. That said I have never used it nor do I plan on it as its a dual din and I am just happy using bluetooth.

I have a JVC unit that works great with my nexus running linaro aokp jelly bean. The unit is x50bt. It will not play through USB only charge. However it is Bluetooth enabled so it can play anything including you phone calls through your car stereo. I have it setup so that my phone auto connects and plays Pandora automatically. The head unit displays song title and artist and also allows u to thumb up or down using the remote conyrol. I also have playlists set up in power amp for my MP3s. The built in equalizer in power amp along with the equalizer in the head unit work well together. I have the USB cable in the rear USB port so it is hidden in my CRZ. The tiny Bluetooth adapter is in the front and does not look out of place.

Per your suggestion, I purchased the X50BT. I am not disappointed. As you said, it does not support MTP, however I have a tiny 32gb Flash Drive(about the size of the Bluetooth Dongle) inserted in the front and the audio quality is simply breathtaking. I have my phone set to auto-connect via Bluetooth, which it does seamlessly. It even connects for audio however the BT audio stream sounds terrible when compared to the USB audio from the flash drive. I don't know if that's a limitation of my phone, the technology or the unit but it hardly matters since I can fit all of my music on the USB drive anyway. I just have to use Bluetooth or the 3.5mm jack for Pandora. Thanks for the suggestion, I really love this head unit!

If you're rooted, you have to tweak the Bluetooth sound profile using voodoo or DSP manager for example (which one your kernel allows).
You could add some "gain" amp or reduce the "Mids" and raise the "Bass"..
I have a different sound presets for the:
-Phone speaker (added some mids)
-Headphones (optimized for my Sony headset)
-Blueooth (lots of bass and "Rock" setting, sound is pretty good)

I just wanted to point out that even if you found a way to force USB Mass Storage, it is unlikely that your radio would be able to read the filesystem. Most radios will only read FAT file systems, while the Nexus uses EXT3 (I think, could be 4). So Bluetooth/AUX are really your only options.

I just installed an Alpine HU, It is also does not support MTP. I really like using the Bluetooth but have found that I have to reboot my Gnex and or restart my car to get the Bluetooth to sync correctly. USB does charge but it is slow. One thing to look for is Bluetooth Parrot.

I am finding that it is more of how my HU looks at my blue tooth. Thus restart car. I am wondering if it has something to do with Android BT. My gnex has worked this way with multiple roms and BT enabled HU.

I bought a cheap stereo from Wal-Mart a Dual stereo with Bluetooth, takes a SD card, front and back inputs and satellite compatible. It has the USB plug that charges but like the others, doesn't read the memory on the phone. I stream through Bluetooth all of the time with Spotify. My son's Galaxy SIII can connect too if I turn mine off without changing anything. It was a great investment. It is a convertible and the microphone works great at 70mph with the top down. For $118 I am very happy.

I don't believe the Galaxy Nexus will work with the USB of many head units since the Nexus uses MTP instead of UMS.
Hopefully someone can come up with a UMS for the Nexus.

I think the better way would for HU to be able to connect like they do to Apple products and have MTP support.

HU
I know that JVC / Ken-wood have apps for android. Looked more like a HU controller rather then playing from android. Never tested.

I think I figured why my USB isn't connecting from the AVH 4000 NEX to my galaxy note 3 SM-N900. It's possibly due to the MTP mode. I believe if the was a mass storage mode that will work, kinda like a USB stick. I don't think the firmware in my HU is properly picking up MTP, all it does is charge the phone. You need a kennel that has UMS enable for mass storage however the international note 3 SM-N900 currently does not have such kernels. There is only 3.... To my surprise. Maybe the last time I ever go with international models again. If anyone finds away around this let me know thanks.

My car does not have USB or card reader, but aux line!.
So I decided to go cheap and buy a Vieta FM Car Transmitter and BT Handsfree unit, and I does a decent job.
Perhaps in a future I'll go for a Parrot...

[Q] Car Stereo Unrecognized By S4 When Connecting Via USB

O-for-two...<grumble-grumble> :crying:
Upgraded my factory cassette car stereo to a new one with usb port (no bluetooth), thinking I could both stream the phone's audio and charge the battery via usb.
Well, the battery's levels actually decrease when plugged in, and more to the point, the phone isn't recognized in usb mode in the stereo and quickly goes to radio mode and the phone displays the following message (please see attached screenshot)...
...my phone is stock, not rooted. Stereo is not bluetooth-enabled, and I would prefer to stream via usb than the aux port.
-> Can anyone advise any tweaks or apps that would enable the phone's streaming audio to be played via the stereo's USB mode?
Thanks in advance!

Thanks for the reply.
It's a 4Runner.
Hoping to focus here on how to get the devices to recognize one another...

That's weird. Maybe a driver issue with the stereo? Does it have a hard drive? Never used stereo with usb port. I think my wife's suv has one.

I have a similiar radio. No bluetooth but a usb on the front and an audio input on the front. As I understand it the stereo itself can't access the phone this way. It doesn't have drivers to recognize the Samsung phone. Think about it. you plug your phone into your computer by usb but you have to download and install drivers for the two to work together. Mine from the looks of it has Iphone drivers built in but nothing for android. You can probably plug a thumb drive in loaded with music and it'll play. What I do is use a stereo cable from headphone output on the phone to the audio in on the stereo. If I need to charge it I have the standard car charger for that.

Youre doing it wrong
The reason the battery is decreasing is the amount of current drawn from the device. Either the radio is not strong enough to supply the right current or the phone is recognizing it as a computer and limiting the draw to 500ma. My rough estimates show that the phone uses closer to 750ma while in use just to run. You can verify how much power it is drawing with this simple application https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
You could try to install a kernel that allows you to override the amount of power drawn from the port. I was the first to request the feature and Ktoonsez was nice enough to implement it into his kernel. Now you can set the AC and Computer USB draw to any amount you like.
Secondly, why did you think you could play audio through USB in the first place? I guess it would be possible if the radio supports MTP but then the phone would be acting more like a USB stick and you would have to choose the files manually on the radio itself.
If you really don't want to use an Aux cable then I suggest buying a bluetooth dongle and connecting it to the rear AUX inputs on the radio. They are relatively cheap and you can install it inside the dash never to be seen again.

Yeah, not sure why I thought I could stream via usb either, must've been mixing up the functions of that and the aux cable.
-> So I'm familiar with a bluetooth dongle that connects via usb (...think that would work properly in a car stereo too?) - but you're recommending a dongle that connects internally? Know where I'd find that for sale?

1st, my assumption is you're rooted...?
If no=Boohoo... Root or buy stereo with Bluetooth.
If yes= install this app... https://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler
Open it, grant it root privileges, click the "mass usb" (I think its called), and profit!
*Music must be on external card.
<-- my thank you is over there

Do you have an auxillary input option on the stereo? 3.5mm jack...
The advantage is that it's guarenteed to work.
The disadvantage is that you can't control the song selection from the stereo. You have to do it from the phone.
Also, could it be there you store the music? If it's on an external SD card I can see where that would fail. Maybe if it was on the internal memory? Remember the car stereo probably isn't real bright. If it doesn't find what it's looking for where it expects to find it, it won't keep looking.
You might have to have it stored in a specificly named directory on the phone too.

"Internally" meaning it goes inside the dash, behind the radio. Its just a bluetooth receiver with an audio output (either a headphone jack or RCA cables)
If you want listen to music over "USB" you can get certain touch screen radios that will mirror your phones display

There is a mod that allows your phone to emulate a usb storage device that would allow you to play music stored on the phone through the stereo you installed, however there would be no controlling any of the sounds, etc via the phone. All the controlling has to come from the stereo itself. Volume, tone, selection, etc. You also need to check the format that the stereo "expects" to see in order for it to be able to function.... Such as Folder size, (files within the folder - how many) How deep the folders are allowed to be set as like in subfolders, etc. What the storage media format is able to be accessed, etc. It gets a little technical and the results are a bit disappointing in the end...
The best I can recommend is a display screen unit that supports using the phone in the USB input. I just installed a Pioneer AVH-X4600BT that works with my (GS4 rooted 4.2.2 Stock ) in my Wife's Subaru Outback. We can plug the phone's USB cable into the stereo (via a Mirrorlink add-on) and run the PHONE using the touch screen of the stereo. You'd be able to run Pandora, answer/make calls, answer/create e-mail and Texting, listen to the music on the phone, watch video that is stored on the phone or DVD's, and most important, NAVIGATION on a 7 inch screen!. All of that though, is dependent on the phone you have. As of yet, the Mirrorlink supports the iPhone, GS3, GS5, and with a hacked app in the phone, it also supports GS4. There is a free app on the market that is called Drivelink which interfaces your phone and the stereo.
You might want to research other stereo devices that have the Mirrorlink application support. I believe Sony has some, but I didn't go past the Pioneer unit. Bottom line, BE SURE TO DO THOROUGH INVESTIGATION ON WHAT YOU WANT TO DO AND THE CONNECTABILITY OF YOUR DEVICES. I know you just bought the unit recently so you just might be having to live with your setup for a while. That's o.k. though, next time you purchase something like that, you will be armed to the gills with knowledge and get something you'll really enjoy.
On my test bench after testing, and was ready to be installed....
Good Luck, and Aloha!

It's doing that because your phone uses MTP as the Media Transfer Protocol. Basically, it kind of mounts like an MP3 player or camera and the new DIN you installed doesn't know what to do with it. The real trick is to get your phone into UMS, USB Mass Storage mode. There's a UMS app in the play store, BUT you have to be rooted to use it. It basically mounts your phone like a regular old thumb drive. Do that and your new DIN will see it no problem. Only thing is, like a USB drive you'll have to navigate into your folders to play your music. This was what I threw in my car and it's been awesome!

One of the things that drives me nuts is that most cars with USB ports have audio playback support for Apple devices because of Apple's dock interface that let's the docking component control and navigate the audio. Unfortunately (and it drives me crazy) Google hasn't created a similar interface for Android so there are no Android Docks. Android devices like the S4 in your car rely on on AUX to send audio. It really sucks and Google has committed to addressing it this year in the car but I don't know if they're fixing the underlying problem of a uniform audio interface in android; meaning one where you plug in a dock and it recognizes your phone and how to access your music and playlists. Again, Take a look at this if you need a quick fix. I know you were hoping your new stereo would do it, but you could easily hide this:

1st, my assumption is you're rooted...?
If no=Boohoo... Root or buy stereo with Bluetooth.
If yes= install this app... https://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler
Open it, grant it root privileges, click the "mass usb" (I think its called), and profit!
*Music must be on external card.
<-- my thank you is over there

I don't understand, am I missing the post where u said u did this and it didn't work?
This is what u need to do... period. If this app won't work with your rom, find an app or place in the settings to enable "mass storage". The above linked app works for me and many others.

[Q] Car stereo with USB and bluetooth for Android tablet navigation

There are so many options that I don't know where to begin.
In fact, I'm rather lost as I can't really tell if a combination of tablet + car stereo will work for what I want to achieve.
Here's what I want to do:
I am using a Samsung Galaxy Tab 3 8" as a satnav with Sygic.
I currently have an old Pioneer car stereo which works perfectly fine for mp3 CDs and radio but I want to change it to a new unit that would accept a small USB drive as storage for my mp3's. I don't care if it will accept CD's or not (even better if it doesn't).
What I want is this new unit to allow me to play music or radio as normal and, when instructions come from the Sygic App (turn left, turn right etc) during navigation, to get the music interrupted and the instructions heard from the car's speakers. After the instructions are over, the music then start back automatically.
The only thing I managed to sort out is that, for this whole thing to work, both devices (tablet and car stereo) must support the A2DP protocol. The Samsung Galaxy Tab 3 8" does indeed support A2DP for Bluetooth (according to specs) but I'm lost as far as car stereos are concerned.
Instead of looking the specs of every single car stereo available on the market today, I thought I would try asking here first.
Does anyone have anything similar working?
Thanks in advance

You may try the "Dynavin Car Stereo"

Separate audio output, only with USB sound card? Anyone used?

Hi,
My receiver has no hdmi, so I have audio put to it from tv. Sometimes I would like to listen to internet radio without having tv on, so direct connection to receiver would be great, even analog one. Do I need USB audio card or there are some other options? If yes, anyone uses something worth mentioning? Anyone tried USB cards on Shield?

I use an external USB dac. Works out of the box and mutes the hdmi sound output too so you will not be able to have it connected all the time for when you want the hdmi to output sound.

That's worse, but maybe I can live with it, maybe I find one with power switch, thanks

I am using a HDMI video / audio splitter. Works well.
Best part it doesn't need to be powered separately.

Does audio go through hdmi and separately? Analog audio or digital? Or maybe can you post name of the splitter?

I have mine setup to do this through bluetooth, where with a combination of apps i simply press and hold 2 on my third party remote, and my shield connects to my bluetooth a2dp reciever which in turn is connected to my stereo speakers, i simply disconnect the bluetooth connection when i want the sound to go through the tv......which i had setup through tasker to disconnect when i long press 2 again, but i think i broke this messing around with this particular task .....that reminds me, i gotta get round to fixing this
I can do this without even having to turn the tv on or even having bluetooth on, as the remote is a RF 2.4gh/IR remote
To take it a step further, i could potentially create a scenario where i press or long press my chosen button and have the shield wake up > unlock display > turn on bluetooth > connect to a2dp > open media app > emulate media play.......and have my music playing without having to turn on the tv.......the remote having media control and volume control as standard........assuming the app supports the media standards i.e. youtube app doesnt
Apps used
Xposed
Xposed additions (can map the remote/mouse/keyboard buttons to something else or have it initiate chosen tasker task i.e. long press 2 initiates "speakers on" task)
Tasker + plugins
Anyway, thats another avenue

I will buy this converter www.goo.gl/VqOvFB

that's what i've been using since my Chromecast to send audio to my speaker bar. I just swapped the hdmi when i got the Shield.

has anyone managed to get 5.1 audio out of the shield via USB soundcard? I bought one but it seems that its sampling down to a stereo sound. I have set in settings 5.1 sound for USB.

I also bought a 7.1 xonar u7 usb dac but no output on surround channel only in left and right. I aready set the USB to 5.1 surround and tried all the video applications. Maybe the shield only supports usb pass through and PSM stereo.

USB Auidio Works with class compilant devices only, but not entirely sure what that means in this case.
What apps did you try and what audio/video source files did you used for your tests?

Same problem here, any progress since September?

im currently using this: https://www.amazon.co.uk/LiNKFOR-Ex...8-1-spons&keywords=hdmi+audio+extractor&psc=1
I connect the toslink to my sound bar so i can chromecast my spotify from my google home and not have to have the tv on. the audio still passes through to the tv, there also is a 3.5mm jack you can switch to.

I use the Audioquest Dragonfly DAC and it sounds amazing. I combine it with the Jitterbug. It's a little pricey (90-100) but I'm running to studio monitors so it's easier to tell the difference in quality.
