Is there a program to use BT headset as remote microphone spy?

Hi all....
I was thinking if is there a program for our Windows Mobile device wich can use the microphone of a bluetooth headset and simply listen to it, making it a ambient microphone spy ...

I don't have my bluetooth headset by me to test it out, but maybe you could use it as a microphone and record it to audio notes (or similar software). Or you could hide a 2nd phone that is connected to the bluetooth headset, call it, and listen in (greater range).

With audio notes I haven't tried... but calling another phone makes it expensive... so I wouldn't use it ...

No one knows?
I'm goung to try with audio notes...
But I was thinking if is there a way to listen in real time... That would be better !

That's hilarious that you want to be all 007. Are you a private investigator? This is an interesting puzzle to solve and I like puzzles.
I would recommend getting a cheap-o BT headset because they suck at cutting out noise anyway. Of course, you'll probably have to be within arms reach of the people you are trying to listen to. Then, use audio notes to capture the audio. Lastly, I would look for some software that will allow you to play around with the different ambient noise levels. I would try Audacity first because it's free and very robust with options.

[Q] Bluetooth Headset Audio?

Hi All,
I have a 16GB TF .. and it's been very good so far. However, I'm having an issue that I think is probably simple .. but google & xda searches don't find anyone else with the same issue.
I want to use Skype over the tablet, but with a bluetooth headset. Using the TF with just the internal mic & speakers is pretty speakerphon-ish .. and I'd like to use a headset.
I have a couple of BT headsets (one of them 2.1 w/ EDR), and I can pair any / all of them to the TF. Problem is, the audio doesn't come through over the head set, and I don't know how to force it to.
The TF (now running 3.1) acknowledges that the headset is connected (to phone audio it says) .. but the only options in the configuration is to remove it.
What am I missing? I see reviews all over the place where folks are using the tablet to play movies in the car, and piping the audio out via BT? I think I must be missing a config step .. but can't find it.
Thanks for your help.

Im kind of in the same boat but I dont think honeycomb has a "phone audio" functionality. Only "media audio," which is what you would use when piping audio to external speakers.
its the same on the phone, those headsets only connect to mono phone audio so if I was playing a movie or music its silent. So for right now I think you are stuck until they figure out how to make specific apps recognize the phone audio device.

Makes some sense .. so it knows there's a "phone audio" aspect to things out there, but we don't have any way to force the Skype audio to be phone audio and not media.
So if I had a stereo headset, would the system work with it and pipe the audio out since it would recognize it as a media audio system?
Where does the mic fit in all of this?

I have a BT combination headset/headphones which I paired with the Transformer, and from testing it I can say the following:
1. The transformer paris with the device and recognizes both the "handsfree" and "media" profiles that the headphones support.
2. The "media" profile (also called A2DP, stereo bluetooth, etc) works fine. I have listened to music in stereo though them and all of the controls like play/pause and previous/next work properly. If you want to listen to movies, music, or whatever else you should be fine.
3. I can hear Skype through the headphones, but testing revealed that Skype is using the Transformer's build in microphone rather than the one in my headphoens. It also doesn't respond to the call button. Thus, it seems to be using the "media" profile to deliver sound.
So, even though the Transformer can clearly recognize handsfree profile, it either isn't passing it to apps or Skype isn't asking for it.
It looks like as long as you plan to be Skyping with the tablet infront of you, you can get almost the same functionality of a handsfree/headset by using a BT headphones instead. As long as you don't plan to leave the tablet in one room and talk in another you should be fine.

hey so i tried Super BT Mono Free Trial and it actually worked. thought it was Froyo only and reportedly broken with gingerbread.
using Samsung WEP450 paired "handsfree" profile, turned on Super BT Mono and to my surprise audio from music player routed to the BT headset. sound is crappy, and so far can't get audio from BeyondPod to the BT headset.
rooted 8.4.4.11 with netformer 1.5 OC 1.6 ghz and juwe11 ram profile.

...
try jabra... coz jabra headset supports a2dp i had the same issues until i bought a jabra

hahaha just wanna keep answering those unanswered questions coz before i couldnt post here and i see a lot of questions left unanswered and i know how it feels just like to help out in anyway

Why aren't bluetooth microphones supported?

I just assumed that I could use any bluetooth microphone for voip, voice recording etc. I currently do not have any bluetooth device but I tried 3 at a friends and they all paired for sound, but failed to work in using a voice recording app or a voip app. In a voip app the sound went strange (long sounds on the dial tone buttons) and then the sound resumed coming out of the tablet even though the headset device was showing as connected. Only a reboot solved this.
So I assume the bluetooth stack doesn't support recording, but why not? Isn't this a basic thing at this point? If I connect a bluetooth headset with mic that should be my input and output on sound for the time it is connected.
Or has anyone had success with a certain bluetooth model for recording?

No one can provide info on this? Is this the norm for tablets? I would assume even some ancient gingerbread phone would work with bluetooth headset/mic.
Does cyanogen team ever modify the kernel to include more functionality such as this?

I'd check other bluetooth threads around this section, but I've heard several people who've used bluetooth headsets with Nexus tablets. It may be a setting issue (particularly the device setting under bluetooth and the app settings concerning headsets).

Same here, Plantronics bluetooth headset works perfectly for voip calls using Talkatone.

Thanks for the info. I don't have the model names off-hand but I'll ask my friend what they were. I wasn't aware that once a bluetooth device was paried that there were any additional options. I was under the impression that it was simply pair and use. With the case of a headset/mic I assumed it was inherited as your sound output/input for all apps while paired. The voip I tried is csipsimple and a voice recording app. I'm glad to at least some models work but I hope it isn't hit and miss and you have to be selective of what bluetooth device you use but rather something I was doing.
I didn't expect there to be any settings as well because even with no bluetooth recording device paired, I don't see anywhere in the settings recording recording (like mic volume).

Can't get mine to work. Single ear set I don't even get sound. Just dead air all around. The Southwing SA505 stereo gets sound fine but no mic function and on Groove ip no sound or mic on single ear or stereo. I even checked the settings making sure bluetooth was selected.

I'm from Canada so I can't try talkatone as I can't get google voice. I now purchased a btheadset. It pairs fine and I hear audio in all apps but I haven't found one app yet that works with the bluetooth mic. I wanted a voip sip app. I've pretty much tried all the free ones and other users have posted comments of bluetooth issues as well. There are a couple of paid sip apps that claim to support bluetooth, but I don't want to buy them to only find they don't.
So yes, android supports bluetooth mics, my thread title is inaccurate, but it seems the vast majority of recording apps do not have proper bluetooth support. Can someone name any app besides talkatone, even a voice recorder that works with bluetooth so I can just test it?
I'm actually surprised it's this bad. Bluetooth audio isn't that cutting edge. It should pair and now act as your soundcard so to speak. I initially thought to blame the OS because I thought any app that requests to play a sound or record a sound, would be re-directed by the OS to now use the bluetooth device.
I'm pretty sure it works exactly like this on windows. Or for example, I have a usb headset on my pc. It shows up as a soundcard. I make it the default and every app now uses that. No developer had to code to use a usb headset/mic, it just works.
Again a little disappointed that it's been a little trying just to get a bluetooth headset to function properly. I tried 3 at my friends that all pair fine and work flawlessly on his playbook in all his apps, and now I bought 1 so it's hard to say all of these bluetooth headsets have quirks and don't work properly with android.

Still trying to get this working. It pairs fine, and shows in the bluetooth details as being connected with phone audio and media audio.
It's a Aluratek ABH01F which I've read great things about. It supports a2dp. I'm not too familiar with bluetooth and microphones so I'm not sure if there is anything else to check for android to support a bluetooth microphone.
I don't know why I didn't think of it before but I tried google's voice search and it doesn't work either. I can hear the audio fine, just no mic.
Can anyone confirm if google's voice search works with their bluetooth mic? You probably have to walk out of the room to verify it's not the units mic that is picking it up obviously.

I'm not convinced bluethooth mics work at all on the nexus 7. I could chalk it up to my headset just doesn't place nice with the nexus 7 but again I tried 3 bluetooth devices at my friends. I found this post on another site:
Well, I got around to testing a bluetooth headset. single earpiece, Avantalk AH28. Not the best, but it works fine with a phone. Paired with the tablet fine. I dialed on groove ip - dial tones came from the tablet, the ringing transferred to the earpiece, when phone was answered there was no sound transmission at all- not from the bluetooth earpiece, or from the tablet. Just dead air. Tried it twice.
2nd test- google music played from tablet- not into the earpiece.
I have a stereo bluetooth headset with mic that I can test with but will have to charge that one up first. Will get back to you.
************************************************** ****
Got to my stereo Southwing SA505 bluetooth test. It worked to play music from tablet beautifully. Did not work with groove IP- went in and made sure settings were set for bluetooth- Mic did not work.

Again, I hear audio fine via bluetooth, so I wonder if some of you were thinking the bluetooth mic was working but it was actually the unit's mic.
This app called tapemachine specifically states it has bluetooth support. It fails for me when I change it to bluetooth in the settings, can someone else try it?
https://play.google.com/store/apps/details?id=com.samalyse.free.tapemachine&feature=nav_result#?t=W251bGwsMSwxLDMsImNvbS5zYW1hbHlzZS5mcmVlLnRhcGVtYWNoaW5lIl0.
So I'm starting to think my thread title is correct. If I am, I'm hoping there is a way to hack some file changing the available audio profiles. I've read others doing something similar with different devices when the manufacturer disable those audio profiles. I would find it doubtful that google/asus would do this though.
Anyway, if anyone can try that app, or confirm that say grooveip is using the bluetooth mic and not the device. An easy test is tap on the unit mic while recording and see if you or the person you are talking to hears that.

No one? I know a couple of you said it worked, but are you sure grooveip is actually recording via the mic? I can hear phone calls using various sip apps with bluetooth, but I know the mic isn't recording. One of the headsets my friend has is a Motorola MOTOROKR S9 Stereo Bluetooth Headphones. Link here: http://www.amazon.com/Motorola-S9-Bluetooth-Headphones-Packaging/dp/B0017KTOJK.
I've only tried stereo headsets, so maybe that is the issue. The Motorola HS850 is a single ear piece, I'm not sure what plantronics set you have.
I'd really appreciate if someone else can verify if bluetooth is working. If bluetooth recording in fact works with the nexus 7, I must be really unlucky with 4 headsets that don't, which I find highly unlikely or nexus 7 has poor bluetooth support. The only thing left is my bluetooth hardware is broken which I find even more unlikely. Aradreamer, you say you've seen several posts saying bluetooth works, but I haven't found one post explicitly stating bluetooth recording works. I found more post on other forums clearly stating it doesn't work.

odd odd ...
first off i have the Nexus 7 16g with it rooted.
heres what i did first i bought the samsung HM1200 didnt thoroughly test that 1 because i figured it just wouldnt work with the device ( or was broken ) once i started to get all this screeching out of it... i heard sound momentarily then all it did was the screeching at different levels. returned it yesterday. then i added a couple more bucks ( about $27 total ) and got the plantronics M20 took it home and crossed my fingers. got it all it paired up and what not and ended up with the same condition except now the mic is working perfectly. i tested this thoroughly now over and over inside and outside and also away from the N7 to be sure the mic is working. this is great BUT i cannot hear any sound at all coming in to the N7 except the same screeching at constantly varying levels. this is with both grooveip and talkatone. i also tried uninstalling beats audio and rebooting but i read somewhere this wont change the drivers back to the originals and i still have the same condition. i just got the N7 about 3 weeks ago and the store where i bought it has a price guarantee so i am today planning to return it and get the N7 again but this time the 32g version. ( they got 2 left so i will be going ASAP. ) so almost all the work i put into setting this thing up is about to be wasted. still i am going to do it anyways. to me its just the point of getting the best i can with my available budget/resources and i can easily see this thing be full and kicking myself in the butt for not doing it. this time around i will test all of what i mentioned here BEFORE i root it. in fact i will only install the necessary apps ( grooveip/talkatone etc.. ) during testing. its a real pain in the butt but it is a MUST i have this thing working as a phone with BT asap. thanks for the input and i will report back later.
update: actually in a more quiet room i was able to hear myself on the BT headset but very very low and in the background behind the screeching. still will report back later with the new unit.

For some reason the Bluetooth headset profile on the n7 is totally broken. I tried MANY headsets and none of them work. It is either the drivers, the hardware or the kernel. I hope it fixable in the 3g version.

yep i am sitting here now with the 32g N7 and the first thing i did was try the BT unrooted and its the exact same thing screeching like mad can hear myself on the mic perfect from the other phone and can hear the other phone low in the background of the screeching on the N7 ugh
i have a temporary solution that should work till its sorted.... i need a new headset for my computer anyways so ill just make sure to grab one that is USB then when my OTG cable arrives i am pretty sure that should work. it will be corded but at least i can use the phone somewhat normally for free. ill let you know. now im off to rebuild the whole thing back to where i had it in the 16.

Bummer. Hopefully they fix it with 4.2 or with the 3G version.
It also seems that if you try to toggle speakerphone / BT headset in various voip apps the tablet will crash and restart.
I tried with GrooveIP, Talkatone and the build in phone app (After changing the framework-res.apk file).
I also noticed i had better luck getting the BT headset to fully (and randomly) work when doing outgoing calls. It never worked on incoming calls.

Any progress on this?
I've noticed the same problem and just returned a BT headset due to the problems in GrooveIP & Talkatone
As a side note I was able to get the BT headset to work as a MIC with the google voice commands by using the following..
- Soundabout
- Under BT settings set it to force mono BT mic
- Set audio to wired headset
Just as ref, I'm using my N7 in my car, so my setup may be a bit different.
But this worked, I was able to tell my N7 commands and it would read out the response over my car speakers.
Anyone had success with a USB mic? Curious if that will work.

I'm very interested in this thread too.
I have a 32GB nexus 7, rooted and unlocked. I have a Platronics M100 bluetooth earpiece. My goal is to be able to dictate to Evernote through the BT earpiece. It is pairing and under the connect settings it is showing up as "phone audio". But when I speak into it nothing is happening in Evernote. I also do not get media audio through the earpiece.

My Sony xperia Z accepts audio from bluetooth microphones, but only during a phone call.
When the call is terminated the paired bluetooth mic becomes inactive and the phones built in microphone takes over. I have tried many apps but none will accept audio from a BT mic.
I have tried a number of headsets and speakerphones and they all behave in the same way. Sound is not a problem as the BT speaker simply replaces the phones internal one when paired.
The xperia Z has a setting which claims to: " record audio through bluetooth headset if available", but this setting does nothing. I keep retrying the setting at every android update, to no avail. Currently at 4.2.2.
When I plug in a wired headset, the speaker and mic simply replace the ones in the phone. Why doesn't bluetooth behave in the same way?
This issue has been raised in many forums, in relation to many android devices, but never answered.

Nexus 4 hands free problems

First post here, so apologies and let the flaming begin but I am trying to determine if my Nexus 4 "issues" are unique to me or normal for this phone.
1. Issue #1 - Bluetooth functions only for numeric dialing, no voice (say name phonetically) dialing or other voice actions seem to work. You can speak the numbers you wish dialed and that's about it. Maybe others can confirm whether this is unique to me. Android ver 4.2.1. Using with a Sena SMH10 bluetooth motorcycle headset
2. Minor issue, but also related - I can not use a stereo headset with my phone and expect the handset mic to work. Something that simply works in every other smart phone I've owned. You plug in a stereo headset (3 conductor earbuds only, not 4 conductor with mic for example) and the phone ideally recognizes the lack of 4th conductor and sends output audio to headphone while using handset mic. So, if you wish to make a call, you can do so. And if you wish to communicate with your phone using verbal commands you may do so as well. You may get "some" functionality using a 3 conductor headphone, however try making a call to someone and it simply doesn't work.
I don't think my phone issues are unique, but perhaps I got a lemon? Nexus support can't seem to confirm whether or not its a known issue.
Anyone else have these "features"?
Thanks in Advance.

Issue #1. Confirmed hands free dialing works over Bluetooth using blue ant s4. In fact I was excited they actually reworked the voice dialer to be accurate!
Sent from my Nexus 7 using Tapatalk

Well that's certainly weird. The headset I am using lists the following profiles:
Key Specifications:
• Bluetooth v2.1+EDR, Class1
• Supporting profiles: Headset Profile, Hand-Free Profile (HFP), Advanced Audio
Distribution Profile (A2DP), Audio Video Remote Control Profile (AVRCP)
The Settings tab of this headset in my Nexus say it is paired for:
-Phone Audio
-Media Audio
I have paired/unpaired and reset bluetooth device to factory.
This headset worked flawlessly with my previous phone, an HTC MyTouch 4G running Android 2.3
When i attempt a call, I get a prompt from the phone "Voice Dialer" that says:
"Say Call, followed by a name or a number"
If i speak the numbers to dial, it works perfectly. If I say the name of any person in my google contacts list, it balks and exits right away, sometimes saying "Sorry, I didn't catch that"

HF Dialing has been horribly broken in Android for some time. You might try disconnecting it from A2DP to see if that helps. For me, since I use a moto headset, I went with Motospeak and it works pretty well.

This works fine for me. I've used it a number of times in the car, where I have a stereo cable to an FM transmitter, and I just tested it with a no-microphone set of headphones: my voice went through the phone microphone with no problems.

I understand your frustration. Hands free dialing is a feature I don't like to do without. After jumping to jellybean from ICS on my fascinate handsfree was horrible.
When I set up my blue ant with any phone it goes through a "transferring contacts" part of the setup. Perhaps this is why it can recognize the peoples names and not just the numbers.
Does your headset "transfer contacts" like the S4?
Sent from my Nexus 7 using Tapatalk

No, the headset is strictly a phone headset as far as that goes. Not a sync device like some cars, etc. In that case, it might work since dialing could be handled by the Bluetooth device?
I'm no expert, but relying on the nexus dialer seems to be the issue. What baffles me is that when not using Bluetooth and using the Google voice search, it actually works. If pressing the "pickup/hangup" button actually launched Google voice actions... It would solve the problem as well as give me further hands free operations such as nav and music control.
Anyone know how to make that action occur with Bluetooth button?
As for #2, I actually called nexus device support, and while speaking to the rep plugged in my skull candy ear buds. He confirmed that mic sounded extremely garbled and not understandable. These same ear buds world fine on my old my touch and my girlfriends iPhone. Both of those phones recognize them as basic stereo headphones and keep the handset mic intact.
I'm going to call them back and just get a replacement today. Screen has done the flicker/vertical lines thing now at least once too.

I'm having bt issues with my car stereo. It's after market that worked fine with my GNex. I can pair it with the N4 and it shows Phone Audio, but then after a few seconds disconnects. Could bt be bad on my N4? I normally have the headphone jack plugged in through aux and can take calls that way, but I'd like to get bt working again.
Update: after powering off the stereo and powering it back on it seems to be connecting ok

Just checked... Blue ant uses its own voice recognition to pair contacts with numbers and thereby bypasses phone voice dialer. That's why it works for you.

I just got a SMH10 as well. I am able to voice dial okay as well as use google music, what I don't like is no access to Google Now without handling the phone (which would require me to stop and get my phone out of my pocket). Not sure if this is an issue with the SMH10, or with android 4.2.x.
I know it's been over a month since you posted in here, curious about your usage and if you have found any tricks to get google now to work in place of the voice dialer only. Since google now should handle voice dialing I am hoping to get that to work so I can also use the navigation when needed.
Sending a note to Sena as well to see if they have a solution as well.

Hands free out-calling issue
As of last week the bluetooth hands free calling feature was working fine on my Nexus 4. A couple days ago I went to call out using the hands free, and the display on my car stereo went blank for a few seconds and came up saying 'Not Supported'. I can receive calls fine, but for whatever reason the hands free voice recognition doesn't want to open when I ask it to now. Anyone have a similar problem?

I've had exactly the same thing happen. Weeks and weeks of working voice dialing through my Blueant S4. Now, it doesn't work at all. Incoming calls can be answered, but I can't dial out by voice.

[Q] Multiple Audio Inputs

I'm trying to remove my car stereo and mount my nexus 7 (2013) in the dash. Certainly not a new idea. Making phone calls seems to always be a hurdle for these projects. Tablet Talk allows you to control a bluetooth headset (like a Parrot) for making and receiving calls, but it cannot control the call volume. No one seems to have a good solution other than use the Parrot volume controller or just go VoIP.
One option is to pump the Parrot's output into the mic on the tablet and then use Mic to Speakers, but then I lose Android's voice recognition, which is not acceptable.
Anyone know of a way to have 2 inputs so I can get the Parrot output into the tablet and still keep the mic available for Android?
