BT ouput on handsfree

Hi Everyone,
I had a strange thing happen to me in the car the other day and I was wondering if anyone had any views on it. As my phone linked up to the cars BT hands free kit the radio cut out as if I was making a call.
To get the radio on I had to turn BT off on the phone.
Interestingly enough when this happened I had Audio manager running. And right enough I played a track and it came out on the cars speakers. This would be quite useful only I havent managed to repeat it yet.
Certainly I get a bit of music in the 'gaps' when I make a call if audio manager is running but that is it.
Cheers,
Andy
!!! come on guys !!!! someone give me some feedback !!!

BUMP
Anyone ? Please ...

i believe theres is a program called bttoggle or btcicle, which routes audio to bluetooth on running it, i use it to route audio thru my bt headset once in a while, a simple search for bttoggle or something like that should sort it, i wonder if i can upload it here... mods if this file is not allowed please delete...
oh the way i use it is i just kept those files on my storage card and put a shortcut for the btaudiotoggle in the programs folder...thats it..click to turn on audio to bluetooth, click again to turn off..

You might want to check if your Wizard is paired with the car BT using A2DP in addition to handsfree mode. If so, that could explain it -- to fix it, just turn off the A2DP pairing on the Wizard, then re-establish the connection when you want to use the Wizard as an audio player.

No A2DP
Nah just a parrot hands free kit in the car. just wanted to be able to play through it as well as making phone calls.

Audio over bluetooth like other HTC phone?

I have had a HTC (I-mate) Universal for years now and still think it was HTC best phone. That being said it was time to move on and I now have the Dream. One thing I loved about the Universal is I could play my music through my bluetooth receiver. I am sure it was some kitchen I had but my question is with the current state of the bluetooth API is there any other way to redirect the signal to work. I am not even sure once google release the bluetooth section if this is possible to create or if its hardware too. Thanks

well i have been listening to music on my g1 while i drive for the last couple of days.. i have a bluetooth enabled car stereo instead of a head set i 've noticed that when i receive a phone call and my stereo switches to my phone i hear my music before the call picks up and after my call is finished and before bluetooth turns off i have my music streaming again. so it should just be a software issue

That was a program on windows mobile that allowed you to listen to music through a normal bluetooth headset. At this point there is nothing out there. Google has said that the bluetooth api is unfinished and will be finished in a future update. From what I understand is the bluetooth api is not available to the public but once it is Im sure someone will make an app to support that.

[Q] Use bluetooth headset mic instead of phone mic

I've searched around on the forums for an answer to this but could never find anything that seems to match up to my issue.
I have a A2DP enabled headset and want to use it with apps such as Team Speak 3 beta, Vent, and other apps. But for some reason although phone media happily plays over onto my headset. My phone continues to only use the mic built into the phone instead of the bluetooth headset mic.
Any apps designed to use the headset specifically work (ie. normal phone calls, skype, vlingo) but otherwise apps ignore the headset mic.
I already tried using apps like BT Mono and Super BT Mono Froyo but they seem to only pipe audio to the headset, but don't do anything at all with the headset mic.
Does anybody know how to get the headset mic to be selected by apps instead of just the built-in mic?
My device is a Sumsung Galaxy S II ( I9100 ). Both Stock and CyanogenMod Gingerbread

good good good

Still hoping someone may know how to get the Galaxy S II phone to use a bluetooth headset mic instead of the built-in mic on the phone.
I'm really stumped on how to do this.

I still haven't seemed to have any luck finding a way to forcefully map apps to use the headset mic. I'm beginning to wounder if it's possible with the Android OS.

I have the galaxy s2 as well and I've retired several different things and have been unsuccessful with anything I've tried so far... Really difficult to drive and use vent without a headset.

Yeah I'm wanting to do the same thing.. I don't spose you've found a way in the last couple of months? Surely it can be done - may need to get a dev to write something for it though..

Sorry Lilfellabob, still no luck. I find it odd it's so difficulty to remap audio settings.
Even in Ice Cream Sandwich I can't find a way.

The app would need to be written to accept it. Its not a matter of your phone. Its the apps. Think about it for a min. If it works on apps made to use it but another app doesn't work then where does the problem lay?

The thing is, typically other apps should be able to re-route the app to use the headset mic. Alike how there are apps that can force other apps to use bluetooth audio instead of the phone speaker, even if the phone/headset can't use a2dp.

Only if the code is there for it to do it. If they don't code it in then it doesn't work.

I'm having a similar problem but slightly the opposite.
I pair my phone to a Bluetooth device that lets me hear phone output on my car's speakers. However, the phone tries to use Bluetooth for the microphone when none exists. I want to force it to use the on-phone microphone. I can talk and talk but no one can hear me, unless I set the phone output to speaker or handset, which implies setting the phone input to amplified built-in mic, or just built-in mic, respectively.
In the Bluetooth settings I can set to use the Bluetooth device for music or phone, but ideally I would want "Phone" to be separated into "Phone output" and "Phone input" so I could uncheck input (and thus use the built-in mic.) This should be implemented at the Android level so that the setting can apply to all apps.
The same problem occured when I wired (2-stripe phone-to-car audio only, no mic) my Palm Pre directly to my car. I just tried with my GNex and it was smart enough to use the built-in mic when a microphone-less plug was connected.

wrong. its in the kernel. the new firmware on the android is is capable to transmit Audio Steam to Headset device as Audio only. i wont go 100% against coding to force it to but if they wanted to theres have to be some kind of exploit to do so. lets say if skype were to find that exploit or code it, it would be probably violate android policy.

Actually, what's going on is Skype is using the 'bluetooth device' hook of some sort, just like other apps that support piping audio to the bluetooth headset. However most apps don't use the bluetooth device API/hook and just dumbly send their audio to 'default output device' and 'default input device' blindly and let the OS or Kernel decide where to send it.
The OS or Kernel when it senses a bluetooth device with the 'media' profile on it is present, it changes the default output device to the headset, but it doesn't seem to bother doing the same for the bluetooth mic for the default input device.
Because apps like Teamspeak 3 just blindly use default audio device because it doesn't use bluetooth APIs in the app itself, I have no way to make it use the headset mic.
I wish someone could make a mod or app that will allow mapping the default input to a bluetooth mic when present.

As far as I know, Skype has problems using the BT mike as well. In fact, they took a user survey regarding the issue for android and iOS users. However, I cannot find the results of that survey / study, and Skype recommendations thereof.
User choice to use BT mike seems so BASIC to me, I wonder how it was overlooked...!

Rooting will crack open the full power of your Android device!

Rooting the device would give apps or the user permissions to modify system audio controller's (idk if it is anything like ALSA or anything..) settings to make app use the audio channel for the bluetooth headset... an example for the Galaxy s2 i9100 i have is the radio app "Sprit FM" has a "volume control stream" setting which allows the user to select what volume "control" will control the volume of the app's audio output
anywho... i hope it helps a little

rwong48, I have now the same problem that you have described. Have you solved it with any app for Andorid?
Thanks!

Solution
I found an app that solves this problem on android devices, it's called btmono and you can find it in the Google store. I tried to post the link but I don't have enough posts under my belt...
Anyways, pair your device, open the program (such as ts3), connect to your server and then turn on btmono. Voila!
Well, I tried to delete this after I saw that you had already tried btmono, but I couldn't figure out how so just disregard this message.

I already tried btmono, sadly although it works for the output audio, it does *not* work with the headset mic. Programs like TS3 will still keep using the phone's built-in mic, not the headset mine despite using btmono. The only thing btmono does is pipe the output audio to the headset only.
Thanks for the suggestion though

I can't believe they haven't fixed that yet. It is so basic...

Hey guys I'm going through the same issues with my note 2. Svoice was the only one that works but its painfully slow and inaccurate.
Anyways I've tried utter! robin and aivc. Aivc works pretty good but at least it uses the mic.
Utter is really promising but no Bluetooth mic. The devs have acknowledged it though. So hopefully soon.
Update: AIVC has one downfall. The app can't open if the screen is locked like utter and svoice can when prompted from bluetooth. Also, it only listens automatically the first time. If you close it without killing the app, you'll have to press the mic icon manually every time (which takes away from the purpose of handsfree).

Howto AutoUse BT Pair for Media Audio?

I've touched on this question before but I may have been using some wrong terminology.
On my S3 I have successfully created a BT pairing with a BT Audio Device use which has a steroe out fed into my car's head unit's Aux In.
So, it is Auto-Paired. That is, when I step into my car and turn on the ignition thus powering up the BT Audio Device the paring is available to be used for Media Audio.
However, in order for my phone to route audio to the BT Audio Device I must enter the phone's BT menu and tell the phone to connect to the Device for Media Audio.
I can either do this through the notification pane to see pairings then tap the pairing to use for Media Audio or I can go through settings->BT and do the same thing.
Either way, it's a huge PITA to do this every single time I get into my car.
There has got to be a way to have the phone automatically route Media Audio through this BT Audio Device upon detection. My previous two phones had nowhere near the ability of my S3 but they had no issues whatsoever with automatically pairing and routing audio to this BT Audio Device.
Is the S3 really this stunted in the BT department? If so, is there an app that fixes this stupidity with grace and non-intrusiveness?

I feel ya, in the past, all I had to do was toggle BT on and go, now there's two or three extra steps which almost defeats the use of a toggle.
I just started searching for some answers and am honestly surprised no one else has made a big deal about this. If I find something, I'll post it up... For now, going to take a look at some system files and build.prop stuff, but it's not really my department.

Got some NFC tags and NFC Task Launcher hoping I could circumvent the BS with a hardware hack. But no, the best this does is auto toggle the BT radio and open the device selection screen where 2 more taps are required to actually use the device for media audio. Any new insight out there? Considering Tasker app but it is rather expensive and no free version to see if it does the trick.

My Bluetooth Auto Corrects Just fine to my cars Bluetooth... Toggle on and go. Running AOKP currently but it worked properly on stock, stock rooted, and Synergy as well.

I haven't gotten a chance to try this yet but I probably will tomorrow.

I haven't had any trouble with bluetooth devices reconnecting to my phone as soon as I power them on. I'm running cyanogenmod 10 rom.
Also you can get free trial of tasker from here tasker.dinglisch.net/download.html

It seems the issue may be primarily with BT Audio Gateways. I don't have this issue with my laptop at all and I'm imagining car head units rarely see this problem.
That said A2DP Volume App fixed this issue for me. Once configured I did have to manually set the device to use media audio one last time before A2DP Volume started doing it for me. I configured NFC Task Launcher to kill wifi, enable BT and launch A2DP volume when it contacts the tag in my car and it works perfectly. Since NFC Task Launcher front ends into Tasker and Tasker has the A2DP force connect plugin available I'm seriously considering getting Tasker for all the other cool features it can do besides scratching this particular itch.

You can fix this relatively easy by getting the app Tasker. I use it to do things like automatically start the music player I want when headphones are plugged in, to turning up the brightness automatically when I am getting an incoming call, etc. I am fairly certain you could set up the program to do whatever you want via bluetooth if you fiddle with it.
Gluck!

LOL, if you had only read the rest of the thread...
Yeah, Tasker cannot do this OTB but with the A2DP Connect Plugin it can. Or you can just run the A2DP Volume app and do the same for free.
That the A2DP Connect code is GPL it would be super sweet if our developers incorporated the magic into the ROMs so that a base install didn't need apps to do something so simple as automatically route media audio to BT gateways.

This happens to me when I use the wrong settings in my cars head unit. My Toyota gives me the option to pair as a multimedia device, a phone or both. If you set it up as just a multimedia device then you won't have some functionality. Check your head unit manual and try to re-pair. You might have to delete the existing pairing for it to work right.

Yeah, it's not a head unit, it's an audio gateway that basically is just a BT receiver with a stereo out and no interface so it is what it is with no configuration options. This issue with the S3 appears to be primarily related to these types of devices.

Oh okay. When I look under the bluetooth menu in CM10 I have a paired connection that I named Car Multi-Media and if I look at its settings I see profiles called Phone audio and Media audio. I'm guessing you just have a Media audio profile. Not sure how to help you there. Sorry.

Route Notification Audio through Bluetooth

I have a Sony Bluetooth Car Stereo BT MEX 3600U. If I get a call the stereo will change the CD or FM Radio to the ringing for my phone, I would like to do this with Notifications as I need to know when I get a text. I'd like to also be able to do the same when I am using Google Maps Navigation. If anyone has any suggestions I would love to know. I may also use it for part of my Software Development Degree.

I second this. My Honda Civic's bluetooth does the same thing. It notifies when you get calls while listening to the radio, but you have to change input to bluetooth audio to hear message notifications and GPS. I would love to hear turn-by-turn GPS while using the radio.
Though I feel like it's something on the car's side that has to change.

IDK, I would have thought that you could merely spoof the phone into thinking its recieving a call or it may even be a simple case of channeling the Audio through a different output. I can't see much detail online but hope this thread may get some answers.

Been researching. Sounds like the car stereo has to be bluetooth stereo audio and hands free compatible. But most car stereo are only hands free compatible.

Possible answer but not fix. I know it's for an iphone but it seems like it's the same problem.

In order to overcome the "handsfree mode only" you can use the BTMono: https://play.google.com/store/apps/...t=W251bGwsMSwxLDEsImNvbS5iZWRvaWcuQlRtb25vIl0.

hmmm thats very interesting but it seams like I just need to force the Audio not to pass through A2DP and instead Use the Phone protocol.
If someone has an APK of the BTmono App It would be very helpfull as Google has locked me out of my account on Playstore

It seams the exact same problem as my stereo will play my phone music if it it set to BT Audio Input. However, It will Always play phone call ringtone.
Edit : After a little research, My Head Unit utilises A2DP for Music, and HFP (Hands Free Profile) for Phone and ringtone.
If I can Modify the route the Notification is sent, from A2DP to HFP then it will work perfectly.

Why has this gone dead !!!!

I've gotten a new stereo about a month ago and everything comes thru my radio even when I have it on Pandora mode it dims he music and my navigation thru the phone comes thru plus my notifications and ringtones that I have set in my phone its a JVC kd-s79bt... Is there anything I can offer to help solve I'm running venom 1.20 and zrboz newest kernel... You can control the head unit thru an app called smart remote its for JVC or kenwood decks with Bluetooth maybe the apk can offer some insights???

That's interesting I might have to see if It is worth buying one of these for my car, Far less effort

You guys are right.. I connect my phone to my ford sync focus and my phone rings but no notifications... Making an app would hurt would it

therion0, I think it would be possible but I am not a dev so if any one could help make this a reality, this thread needs to have a few developers on board.

Microsoft Windows Phone 8 can do this
My friend has a Nokia Lumia 920 running Microsoft Windows Phone 8 and his phone does this. His car actually says "In Call" when his phone reads notifications to him (and then waits for spoken commands to act upon them).
Why can't Android?
