Android as bluetooth headset and/or headphones - Android Software/Hacking General [Developers Only]

Hi All,
Is there a way to make my Android phone (whatever it is) as an bluetooth headphone/headset?
I'll try to explain it in other words. I want for example route all my PC AUDIO STREAM (IN/OUT) to my Android via Bluetooth and manage it from Android.
So the end configuration would be an Android as an headset able to stream the audio from Android's Mic to my PC and to receive an audio from PC.
Same thing as between two Android Phones.
I mean, when i'm receiving a call, it would be nice to forward that call to another Android phone via bluetooth because the other Android phone will be like a Bluetooth headset.
I'll really appreciate all kind of suggestions.
Thanks
Francesco

i was actually thinking of the same idea last night..but i couldnt find any app that could stream audio from my pc to the phone..
may be i didnt searched enough?

I am also searching for something like this.
Did you find an app that could do it?

I did some searching both online and in the market myself and couldn't find anything related to these purposes. I would like an app for this so that I can lay in bed and watch a movie without disturbing others with the audio. I could just listen to headphones through my Droid X.
The most likely software developer to develop something like this, and has yet to make any smartphone appearances is Soundflower. I love Soundflower on my mac and it makes so much sense that they would develop an app for something like this.

i'm looking for app that will enable my phone to call(and make conversations) trough other phone via bluetooth.did anybody come across such app?

Hi, digging up, I was looking for this kind of feature to watch movies fullscreen VLC on my desktop computer from my bed, without having to buy meters of extra headphone cable or a wireless headphones.
I came accross Jamcast which uses wifi network instead, but it's much too complicated, laggy, and expensive shareware.
Bluetooth is the way to go, but we need to be able to use android as a bluetooth headset.
Anyone got news ?

I'm also interested with doing this. Found any app for this purpose?
I've searched for a while, and found none.

BUMP. this could save me from buying expensive headset which can't even last 1 day!!!

Someone custom-implemented the needed Bluetooth role
It looks like some Android device has custom implementations of both A2DP sink role and HFP hands free unit role. I can't post links yet. Google this:

[REQ] Phone --> Bluetooth Speaker

Ive been searching around but can't 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. I have also discovered that many people have TVs supporting bluetooth headsets who would love to be able to listen through their phone.
there is wifi option: twonkys media server. or xmbc which i have been pointed to however I have discovered I am unable to connect to the wireless due to security issues. battery life would also suffer more.
any thorghts on this?
Been a while, but did you have any luck?
I'm looking for a way to deploy my WinMo phone as a Bluetooth Audio Sink, i.e. receiving stereo music on it & relaying that through either its speaker or connected headphone.

Question: Can a Bluetooth phone be used as an A2DP receiver?

I am too cheap to buy a bluetooth headset. So,
"Is it even possible to stream audio from a laptop or any other music source to winmo phone over bluetooth or wifi, so that I can use my current kickass wired mobile headphones"
Ive been trying to get something similiar to work myself, any progress from other members would do well posted here lol

Did you get any progress with this? I would like to play my laptop (Ubuntu) music on my phone whilst I go into the kitchen (for example) and I can't be bothered taking me laptop down. If not, I may have to find some wifi solution (though I'm not being too optimistic).
Yes it can work - but - you need a A2DP source that can transmit to the phone...
There is a product that nokia do that I have which is a A2DP gateway box which can either act as a receiver or transmitter to an A2DP phone - but I am not sure what protocols it needs to work... I assume, but dont know, that it works with general A2DP because it will receive from my S710 & Touch Diamond phones - although I have tried the transmit part of it yet the documentation clearly states it will transmit...
the device has phono stereo input & output ports which can be rigged through to whatever sound source you have in mind...
As I say though I havent personally tested the A2DP transmission facility but I very much doubt Nokia would say it worked if it didnt...
Hope that helps...
Well, if I already have an A2DP source, how would I go about getting the phone to recieve it?
news about it please?
I was about to start a new thread for this lol
I want to stream music from my macbook to my phone, and hook up my phone to my home stereo. That way i dont have to waste money on a a2dp receiver when my phone has the capability.
Is there an app for that?

[Q] Pairing Tablet as Bluetooth Receiver?

This topic is pasted all over the net and it doesn't seem to be getting much attention, however I think it should be brought to a better light.
The idea is simple: Enable your Android Phone or Tablet to become a bluetooth reciever(to replace a headset or bluetooth speakers) and broadcast audio to the device and broadcast microphone from the device.
This could be used in several different applications:
1. Using an Android Tablet as a Car Stereo Interface
(Connect Phone to Tablet Via Bluetooth and use it as a hands free speakerphone, or aux out to your stereo)
2. Multiple Android Phones
(Have a business and personal phone? Answer all your calls from one.)
3. Phone or Tablet as Bluetooth Speaker/Mic
(Skype, PS3, Xbox 360, TV, Google Voice)
I would use several of these options on a daily basis, and would most definitely pay good money for an app like this.
So my questions are:
1. Is this possible?
2. If it is, how hard would it be?
3. If it isn't that hard, why hasn't someone done it yet!?
Bump if you want this too!
Just wanted to bump this because we need to put our heads together here and get this done. I need this capability for number 1 on your list of potential uses. I also would pay good money for an app that enabled this. Phones and tablet are rooted and ready to modify whatever is needed. Ii've bumped a couple other threads today as well.
I would also pay for this!
I have been looking for this for a while. I use an old LG Eve in my car and my Captivate's Wifi connection for GPS but I would love to have it work for calls and music too.
I would pay as well.
bumping this just to say that I'm going to research the rules and process for starting a bounty. obviously the smart people we need to work on this need motivation lol
Sent from my GT-P6210 using XDA Premium HD app
Hi there,
just wanted to leave an incentive kind of post to say that I've also been looking for exactly the same thing.
My hunting on Google play just stopped after finding this post on XDA.
It's a kind of confirmation that there isn't a solution yet.
Since our rooted androids are more than capable of acting as a Bluetooth receiver, whether they may be based on new or older hardware, this seams like a very logical step in their lifecycle instead of getting forgotten in a drawer full of old and unused electronic waste.
Some doubts:
is a2dp required for this?
Is a2dp hardware related or simply a software feature?
Personally, I could live with a simple one way communication from a phone with mobile network (sender ) to the receiver. The used mic could still be the one on the sender side.
Wouldn't even need to have the receiver in a visible place as I would just connect a stereo cable from its headset output to an aux input on a hifi or a car stereo to hear music or acting as a hands-free system.
Hope this gets some real attention.
Cheers
In one year, nobody found a solution??
I can't beleive there is STILL no progress on this. Maybe I'll try asking a dev that has made similar apps the feasibility of this. There are so many practical uses for this that I cannot beleive no one has capitalized on it.
This would be a killer app if done right. Who here doesn't have an old phone laying around gathering dust? This could start off small; simply enabling the phone/tablet to be essentially a Bluetooth speaker, but then gain features and an interface using A2DP, which would evolve it into a killer way to make any car (with at least a tape deck) able to have full Bluetooth integration and control. I really hope someone can do this!
Bump
Bkb -> p -> PC (either wifi/blu/usb)
yeah so a spare bluetooth phone that connects between a keyboard and PC. Acting like a BT dongle. No way I'm spending 10 bucks for that. if an app...maybe a buck but would prefer free.
looking for this too. Wanting to turn this old phone into a bt audio receiver
Wow, endless searching and now this thread and still nothing :/ i need it for the first idea you listed, did you ever find something?
https://android.googlesource.com/pl.../java/android/bluetooth/BluetoothHeadset.java
Currently the Android Car Multimedia receives Bluetooth Stereo Audio from Phones (Andoird/Apple), how they do it?
Any news?
So many years and still nothing?
May be this is not the right way to do.
I know this is a crazy old subject but others have commented so I don't feel so bad.
I want to make my own android system for my car. I have everything I need for it (hardware/software-wise) except for this one thing.
A few years back there used to be an app called Tablet Talk, it's not exactly what we want but I'm still willing to settle for something like that. The way it works is phone->tablet->handsfree Bluetooth speaker. You could make and receive calls (including seeing the contact names/phone numbers on the tablet) from the tablet itself, then the audio/microphone goes to the handsfree device. Another added feature was when a call is happening the app stops all audio coming from the tablet until the call is done.
Like I said before, it's not perfect but at this point, I don't ever see it happening any other way. I found the app a few days ago, it doesn't exist on the app store anymore, unfortunately, I could get it to run. It just kept crashing.
If anyone knows of something then please let us know.
Years later, found just this thread: I want to do similar thing: Use a private phone (for my sake rooted with custom fw) as a hands-free bt device with an unrooted business phone (non-rooted and secure managed with company tool). I also don't want call forwarding or similar. Just do and answer calls, use phone book and call list via bluetooth like my car radio do for years.
Is there still no solution?

Use Windows PC as handsfree/speakerphone for calls with Android phone

I am referring to attached screenshot which is from a tutorial on Youtube, at https://youtu.be/q2_Q_m7hGxs (at 02:54)
In the tutorial instructions are given for making calls with a mobile phone (presumably Android since the model shown is an HTC EVO) through a PC's microphone and speakers. So in other words, instead of using the phone's own speaker and mic, or a connected headset, all audio goes through the PC.
Note the option "Headset and speakers" in the screenshot.
I have tried to replicate this with my Windows 7 Pro and Xperia Z4 to no avail. No such option is available.
Does anyone here know what the missing part is? Does this functionality depend on the Bluetooth stack installed on the PC? If yes, does anyone know any stack that offers this functionality? If it isn't the bluetooth stack, then what is it?
Thanks.
For posterity, in case anyone else needs this information. I found a solution slightly different from what I first wanted but which may be even better. Details below. But first a word on the original solution I was attempting. Android does not support this. Nevertheless, some Bluetooth stacks on Windows implement this, somehow fooling Android into believing that the connection is to a bluetooth headset, not to a PC. The stack that was mentioned here and there is the one from Widcomm. I tried installing this on my PC but failed.
And here is the solution I settled on eventually. Instead of messing around in Windows, I bought a bluetooth hands-free device designed to be used in cars. Only that I also use it on my desk. And even in the kitchen when I'm busy there. The model I bought is the Jabra Freeway but there are others. Works like a charm. Why it's better than what I wanted: because I can use it everywhere, including in my car where I also listen to podcasts and YouTube talks on the thing. And also because it allows me to conference parties on Skype (on my existing PC setup) with parties that call me on my phone, the traditional way.
I've combined this with a software called Just Remote Phone to control my phone from Windows. Perfect! (www.justremotephone.com)

Help using a tablet together with a phone in a car

Hello!
I hope getting some help & ideas for a new idea I'm trying to use in my car.
I have an old Volvo, with next to no modern entertainment options, meaning a factory built-in radio (neither DIN nor Double-DIN), with no bluetooth or anything fancy. A good radio with a really good sound and equalizer (DolbySorround), but that's it. And a seperate navigation system with no online connectivity or recent updates what so ever (last update is from 2014 for a nice 300.-€).
My idea would be:
Tablet (in my case a Fire HD8, unlocked, rooted and with LineageOS 14)
Phone (Xiaomi Mi Mix2, as well with LineageOS, but LOS16)
Bluetooth receiver from Aukey (that I can wire in with the equalizer)
So far, so good. But here comes the problem:
I want to do some things on the tablet, like navigation, music streaming and calls. Is it possible, to connect phone and tablet in a way, I could start the music (Amazon, Google and my own Nextcloud) from the tablet, where in reality the phone makes the connection and "sends" the sound to the tablet (and from there the tablet to the BT audio receiver) or directly to the BT audio receiver, as long as I can control that from the tablet. Or the navigation (tablet) can use the internet connection from the phone. And last thing, I want to make or receive calls on the phone, but I would like to control that from the tablet as well.
I think you get the idea, what I'm trying to do here.
I'm really not sure how to start, the hardware is already here, but I'm willing to buy other stuff, as long as it works afterwards.
Any ideas or input is very welcome, I'm a little stuck here. Thanks a lot in advance!
