A2DP Connect - Multiple devices - General Questions and Answers

Ok, perhaps this exists already and I'm just blind to it-
I'm trying to find a way to make initiating an A2DP connection between multiple headsets easier.
No, I don't mean at the same time- My goal is perfectly rational and rather simple: I have multiple A2DP receivers (headset, home stereo receiver, 2 car stereos), and I want a simple way to connect to them from the phone.
Normally, one has to click through a staggering number of screens to accomplish this.
Start-Settings-Communication-Bluetooth, select headset, press-and-hold for context menu, hit "Use as wireless stereo". This should be a much simpler process, especially since standard feature phones can do this in a few clicks.
I thought that perhaps A2DP Toggle was the answer, since it claims to be able to toggle A2DP/Speaker from the today screen.
The problem is, A2DPToggle only supports one headset.
In other words, it only reconnects to the last device it was used with. If I just used BT Stereo in my car, when I get my wireless headphones and hit the Toggle, it will sit trying to connect to my car instead of finding my heaphones.
Eventually it will give up and timeout.
What I want is an app that is easily accessible that will either A) display a selection of previously paired headsets that the user can pick from, or B)cycle through a list of headsets, trying to find one that is nearby and on (I understand that this may prove more complicated and less reliable than option A).
That being said, is there an app that does this, or something similar, already? If not, anyone want to help me develop one?

Moved to Q&A

why don't you suggest this option to the creator of A2DP Toggle.. maybe he'll add it.

I've tried already, mentioned it a while back and got a "maybe in the future" sort of response. I posted on his thread again a couple of days ago, and started this thread in case he's still not interested.
I'm honestly pretty surprised no one else was interested in this before me- am I the only person who has more than one a2dp receiver paired with his phone???

I don't use it at all.. but I can see why someone would
as it seems nothing like this exists.. maybe you can change the thread's subject to [REQ] to request an application.. maybe another developer would like to work on this.. tho.. sometimes people demand some money for it.

Jabr BT250v Bluetooth Troubles

I'm having trouble with my Jabra BT250v and my Fuze. The Jabra always worked perfectly with my Nokia phone so I don't believe it's a problem with the unit. The first oddity I noticed is that it paired automatically without asking for a code. After researching this I found out that the new Bluetooth driver does this by design with non secure items like headsets and such by trying a series of commonly used codes like "0000", "1234". That's all good and well, and it does seem to pair up, but I've read that other devices have trouble being bombarded with codes like that and even though it shows up as paired, it doesn't work. I'm not sure if this is the cause of my problem or not, but is the only obvious thing I could pick out.
I've tried putting the ear piece back into the charging cradle to reset it before trying to pair it. I've tried the standard pairing procedure by turning the device on by holding the power button for 8+ seconds until the light goes solid. I've tried the alternate method of holding both the power and volume up button to pair it in the handsfree mode. I've manually set it to handsfree mode once the device is listed on the phone. I'm really out of things to try to get this going.
Basically it pairs and all looks good but I don't get any sound out of the unit and trying to initiate a call or redial does nothing. The phone just keeps going as if it never paired up at all. I'm hoping someone has some more ideas I could try as I would really like to get this working. I wasn't sure if there was a way to just re-install the Bluetooth stack, or even an alternate Bluetooth driver I could try. If it does have something to do with the auto-pairing feature, does anyone know how to disable this? I'm willing to try damn near anything that can help me pinpoint the problem. I haven't been able to locate any Bluetooth troubleshooting tools and even looked at the service manual, but they just put it through a simple test and it doesn't delve into anything deeper.
Lastly I should mention that I am able to use Active Sync over Bluetooth with my laptop and it does ask for a pairing code so I'm really stumped. I guess it is a possibility that the Jabra is messing up since I last used it with my Nokia about 2 weeks ago, it just seems highly unlikely. Any help would be greatly appreciated.
Many Thanks,

bluetooth carpc wm program - cdma

Ok, I really didnt know exactly what to put for the title of this because its a pretty strange request.
A little backbrief: I have a CarPC setup with a 7" touchscreen in my dash, a computer in the trunk, a bluetooth module, a microphone, runs through the car speakers, and running a front end called RoadRunner.
Basically what I'm looking for is:
1) The ability to call out and answer phone calls through the CarPC (full computer). - Using the RoadRunner program there are some interupts built in so that it will automatically stop the music and switch to a screen that has the phone "skin", but I'm not sure what it all entails to make that portion work yet.
2) It must connect through bluetooth
3) The ability to read through the phone's address book and/or store the phonebook in the CarPC.
4) Speach activation would be nice, but not a 100% must have necessarily
5) The ability to read/write text messages would also be nice, but not required
Essentially the skin should be similar to this link:
http://www.mp3car.com/vbulletin/road...oadrunner.html
But the problem with that particular skin is that there is no support for WM devices, that is unless you have another piece of software called phonecontrol.net, but that software is now discontinued, so there's nothing for WM devices.
Now, I'm not asking someone on here to build something for me necessarily (even though that would be nice) but I am not sure what phone protocols there are to connect the bluetooth and use it, or if they are specific to the bluetooth adapters (bluesoiel, microsoft stack, etc) or if its all in the phone, and whatnot. I've got a good coding background, so its possible I can develop something, or modify something to work, but since there is a wealth of knowledge on this forum I figured someone on here might have some know how and ideas.
Thanks

[Q] Truely Hands Free Bluetooth

Hello Forum,
I have been searching the net for everything related to a true hands-free bluetooth headset and cannot find one. I am looking for one with a2dp technology, voice-dialing, voice-answering, and the ability to connect to multiple devices at once.
The best that I have found are ones created by BlueAnt however it requires that you hit a button on the headset to activate the voice dialing feature.
I even found a switch that could be added onto the bluetooth but it cost around $300, which is ridiculous.
I am looking for something completely voice-activated as I am in a power wheelchair and hate having to stop driving to either call somebody or answer a call. It is hard for me to reach for my ears. I even tried looking for a combination of app and bluetooth but to no avail. I have the HTC Evo running android version 2.3.3.
Hope somebody can find me a solution.
Thanks,
What you are looking for may be hard to find because while our tech has jumped by leaps and bounds in some places (voice recognition for instance), it has stayed relatively the same in others, namely battery tech. Your phone and your bluetooth device, could it be found, would die very quickly were they both to be constantly listening to and interpreting voice commands.

[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?

Multiple Bluetooth devices connected to HTC U11

Similarly with the phone call you may select different devices without disconnecting, or simply select pickup on the preferred device. See url below from the lg v10 manual.

I have no idea, it works, but why in the world are you posting in any random thread about the operating system? Start your own thread maybe and leave us to talk about the OS?
Went a bit off topic in the slice of pie thread. Rightly directed to create a new thread.
So basically in summary, the HTC phone is the first phone I have that does not seem to be able to handle multiple bluetooth devices well. In other words you have to disconnect the headset on the HTC to use your car phone. With my other phones you can select which bluetooth headset you wish to use, or when you receive a phone call the first device you press answer on you can use. With the HTC you can only answer the call using the device connected. Wonder if there is a fix hidden in the settings? Even my older phones could handle this.
