Buetooth signal range :(:(:(:(:(

Hi,
i have a very disapointing situation with my NOKIA HS-12W. I have this gadget from 2 months, and now everybody started to complain, that they cant understand our conversation when i am using my headset. It is only 70 cm from my device when i am driving, it is in th holder. But the sound quality is good only when there is less than 20 cm between the device and the headset.They said, that the sound is noisy and they hear only parts of the words. Do you have the same experience, and is there any solution for that? Or i should reconsider the value of the bluetooth feature of this devce.
Many thanks for any help

jep same situation here. got a t-mobile Rom installed and also using Nokia HS-12W. only the first week i reached the +- 9 till 10 meters distance. I have changed some registry settings and now it doesn't work any more. just 20 cm for stereo sound and a lot of stuttering.

i get almost 30 feet from my HT820 and i-take bluepro headphones. i haven't tested my Jabra250, but it's probably pretty good.

Yes, i tought the same, that i have made some registry changes which caused this. But now, after a hard reset , without any registry changes i have the same problem

same here... I've set my registry setting to medium quality so I've reduced the stuttering when it's on my side on my belt. When it's in headset mode I can move further but I can not move as long as 10 meters... s..cks.
Other choice was the SE HBH with the same design I think a 'normal' headset cannot be worn on the streets...

I have the Sony Ericsson stereo bt headset (simliar hang-around-the-neck style as the Nokia). When listening to music, I can't move the phone any further than my belt-clip without having the sound break-up.
So, in my experience, the maximum effective range is 10-20 cm. :x

wich ROM versions does everybody using?
Mine is: UNI_TMNL_130115_130233_11003_WWE_BL101_Ship
this is the latest T-mobile Rom what i know.

I am so sad. Until this i was so proud of having tis device.Today i talked with the QTEK service here in Hungary, and what they told, made me disapointed.They told, there was no solution for that.The Bluetooth antenna is too small, and there is nothing to do. So what is in the specification is a big lie. And they knew it. All we could do it to sue them . This device is to big for using as a standard phone.But with this bluetooth feature there is no other option

The Bluetooth Antenna on the Universal is fine, I can use Bluetooth ActiveSync to connect with my PC and it keeps signal even if I stand in the next room - so the problem is probably your Bluetooth headsets having a weak antenna, not the Universal...

I also have no problems with the bt range for transering files & synching. I also was satisfied with the range & quality with mono bt headsets for telephone calls. However, for bt stereo the range has been quite disappointing.

hello where in the registry did you change those setings ?.. i want to try it out

me too wanna try this.

Having issues with BT on a Lightspeed Zulu (aircraft headset)

To my knowledge, this is the first aviation headset that allows a BT connection to a phone you can talk on the phone hands free while flying. I can get it to connect and make/receive phone calls without a problem, but there is a semi-obnoxious hum/high pitch/static noise and I can't seem to make it go away, and also a ticking sound that increases and decreases volume at random. I've read about other pilots having great success with the BT portion, but I'm wondering if maybe the Tilt is only "compatible" with certain BT devices. Anyone have any thoughts/knowledge on the selective compatibility issue, or have heard of similar issues with BT in general? This is an incredible headset worth the money with it's MP3 input, noise cancelling, and everything. I'd hate to have to consider taking it back because I can't use the currently exclusive BT feature.

BT is comprised of a series of standards defining each individual interface type. I would wager that the problem is with the headphones more so than with the way BT is implemented in the phone.
That said, you can confirm the performance by swapping headsets or phones to see if the problems shifts.

Crackling bluetooth

Hi all,
I have the Plantronics Discovery 975 bluetooth headset which has never given me problems before on previous HTC phones, but I now hear crackling whenever someone speaks...
Are there other bluetooth headset users with the same problem?

+1 voyager pro sametimes cracle sometimes no
Sent from my GT-I9100 using XDA Premium App

We bought two SGS2 and two Plantronics Discovery 975 Bluetooth headset at work. I got one of the phones and one of the headset and I'm having the exact same problem as you have. My other colleague who were happy enough to recieve the other phone does not have any cracking noise which is rather weird.
I even tried my headset connected to his SGS2, i had to make sure my head wasn't messing up the signal or something lol... and it worked fine, so it's something with the phone i guess.
In this thread they talk about KE7 having a new sets of Bluetooth profiles and what not. Perhapes Samsung recognized there was some bug and changed things around.. But i'm only guessing here.
In case anyone is wondering:
Yes, both phone and headset was fully charged when tested.
Yes, both phones and headsets were tested in the same room around the same time so it cant be interference from external sources as it didn't bother the other SGS2.
I'm using KE2 over here. I forgot to check what version my colleague is using but we got the phones the same day from the same store so I bet he is using KE2 as well.

Did both phones have WiFi enabled or disabled?

Come to think of it, I think i had it enabled on mine but not on the other phone. I'll try compare them again and this time have wifi off on both phones.

I had a 975 for about two weeks before I returned it. I wasn't getting consistent performance on either my G2 (HTC), G2X (LG), or Vaio P (Sony). I replaced it with a BlueAnt Q2 and didn't have any problems with the same devices. It works really well on the SGS2 for phone, media, and Voice Talk. The 975 also wasn't A2DP and I like to listen to music and audio on my headset sometimes.

I tried disabling the wifi, not sure if its just now or not but, it seems to be working better. I still hear the crackling noise every now and again but not like before. However i think i will keep using my SE MW600. It delivers more solid performance and the sound quality is better as well. Maybe it's because the MW600 supports A2DP.. i cant really tell.

HTC HD2 Tmobile USA I am also having serious crackling problems...to the point of contacting Plantronics to replace my Voyager Pro and pay $49 for refurbished headset. Distance to phone 2 feet and only getting 1 bar on bluetooth strength. Any sort of obstruction like moving head between headset and phone still at 2 ft away...noticeable crackling and 1 or less BT signal strength on phone. With Wifi enable crackling increases. Connecting to a linksys router just 3 ft away is quite fast but still only 3 signal strength. Turning off bluetooth causes a rise in wifi signal strength but zero bars if more than 10 ft from router. I hard reset but problems still existed.
Extensive research on the problem came across issues about bluetooth and wifi electronics on circuitboard are side-by-side and has something to do with the negative affect on each other.
Anybody have similar "crackling" audio or crackling sound and / or LOW signal when close to phone or wifi routers. I welcome any suggestions at this point.

Jawbone and bluetooth crackling
Hi,
I have a Jawbone Prime which I used for my iPhone 4, which was crystal clear, now I've used it a couple of times with my S GS2 and so far I'm struggling to get a clear call quality.
I thought it was the headset but I have tried it with a friends Advantax speakerphone and that happens the same, every 10 sec's it goes quite and crackles to the point that it's impossible to actual have a conversation!
My phone is only 3 weeks old is it worth exchanging it or will I get the same problem if its a software issue??
Help please
BTW I have just spoken to a lady from Samsung about this issue, to find out if it is a handset issue or software. After being passed around saying it was the headset, though I explained I have tried another 2 headsets, she now said my headset is not compatible.
When I asked her for a list of compatible headsets she put me on hold and then came back saying 'Please go to an accessory store to find out'.
I don't like being fobbed off but I believe Samsung are doing that to me and everyone else! I asked if they were fixing this issue, as there are other forums of this issue, she couldn't answer that question funny enough!
I'm now going to try another handset with my sim and the headset as I work in CPW, finger crossed!

I don't know if I am having the same issue as you guys. You are describing it as "crackling"? My connection falls into a state where the audio sounds as if the bandwidth is REALLY low. So the other person's voice is choppy - really fast choppy - I don't mean intermittent sound.
If I briefly transfer the audio to the phone and then back to the handsfree device again it clears up.
This happens in my car which has a Parrot CK6100 and also our BMW mini built-in bluetooth system.
I have a UK Orange branded SGS2 with KE2 firmware.
Could someone try doing the above and see if it clears up the audio?
As a side issue, stereo audio over a2dp works without problems so it is not a signal strength issue.

Better with wifi off, but still crappy sound.

I have been having a problem with my bluetooth crackling in my car for a very long time now. I did a search and found this very old thread. I wanted to bump it up to see if anyone else is having a problem like this and if there is any known troubleshooting steps we could take. As previous people have posted, stereo bluetooth works fine, its just on calls with my car that it intermittently crackles. I can toggle the connection to my phone and back to my car to clear it up, but who wants to do that? This happens nearly every call. I thought it was my car so I ignored it but I recently tried my phone in a different car and had the same issue. Ironically, I never have this issue with regular bluetooth headsets, only with cars. Anyone else have a problem like this?

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.

[Q] Bluetooth audio quality

Is there any way to fix the bluetooth audio quality other than switching to a CM-based ROM?
My old phone over bluetooth sounds fine. My S4 via a wired connection sounds fine. My S4 over bluetooth sounds like everything was sampled at 32 kHz. All other equipment is the same, so I'm relatively sure it's a bluetooth-specific issue. My girlfriend's S4 does the same thing.
So, any fixes? I'd really like to avoid switching to an aftermarket ROM right now.

Random guess: Could this issue be caused by the adaptive sound feature? I'm not a true audiophile, but I haven't noticed a problem through my receiver in the car or at home.

Try playing something with cymbals and a lot of treble. Turn the volume up a bit higher than normal while still maintaining a reasonable level. The cymbals sound like someone is smacking a plastic grocery bag with a stick instead of being crisp and clean like they should be. I can then disconnect the S4, connect my old phone, and play the same mp3 without any sound distortion. Or I can play the same mp3 from the S4 via aux and it sounds fine.
Try it on both bluetooth and aux. If you truly don't notice a difference, I guess it must just be my phone. If it does do it however, you definitely don't need to be an audiophile to hear it.
My old phone had the exact same problem until I moved to JB on a CM build. The problem there is well-documented as existing on the S3 (try looking up bitpool settings), but I kind of figured they would have fixed it by now. I'm coming from the world of HTC, so I was hoping there is a fix for Samsung.

Sorry to revive this thread, but I have an update.
My car has built-in bluetooth for phone only, so no a2dp. I have a third-party bluetooth adapter that I'm using for music.
I've found that when both of these are connected, the audio quality (especially on trebles and guitars with distortion) is absolutely terrible. That was the point of my original post. Since then, I've determined that this happens ONLY when I am paired with both my car and my third-party bluetooth. I can actually pair and unpair from my car in real time and hear the audio quality immediately get better/worse. The quality gets worse immediately when it pairs, even if the car bluetooth is not in use (but still connected).
I've verified this is the case with both my phone and my girlfriend's S4. Can anyone with such a setup verify this does or does not happen for them? I'm thinking this is a bug with the bluetooth stack, and it'd be nice if it could be fixed. If anyone can try pairing to two different devices and confirm my problem, I'll start a bug report with Samsung. Otherwise I'll try another bluetooth adapter for a2dp.
